附录Hydraulic SystemHydraulic presser drive and air pressure drive hydraulic fluid as the transmission is made according to the 17th century, Pascal's principle of hydrostatic pressure to drive the development of an emerging technology, the United Kingdom in 1795 •Barman Joseph (Joseph Barman, 1749-1814), in London water as a medium to form hydraulic press used in industry, the birth of the world's first hydraulic press. Media work in 1905 will be replaced by oil-water and further improved.After the World War I (1914-1918) ,because of the extensive application of hydraulic transmission, especially after 1920, more rapid development. Hydraulic components in the late 19th century about the early 20th century, 20 years, only started to enter the formal phase of industrial production. 1925 Vickers (F. Vickers) the invention of the pressure balanced vane pump, hydraulic components for the modern industrial or hydraulic transmission of the gradual establishment of the foundation. The early 20th century G • Constantia scofluctuations of the energy carried out by passing theoretical and practical research; in 1910 on the hydraulic trans- mission (hydraulic coupling, hydraulic torque converter, etc.) contributions, so that these two areas of development.The Second World War (1941-1945) period, in the United States 30% of machine tool applications in the hydraulic transmission. It should be noted that the development of hydraulic transmission in Japan than Europe and the United States and other countries fornearly 20 years later. Before and after in 1955, the rapid development of Japan's hydraulic drive, set up in 1956, "Hydraulic Industry." Nearly 20 to 30 years, the development of Japan's fast hydraulic transmission, a world leader.Hydraulic transmission There are many outstanding advantages, it is widely used, such as general industrial use of plastics processing machinery, the pressure of machinery, machine tools, etc.; operating machinery engineering machinery, construction machinery, agricultural machinery, automobiles, etc.; iron and steel industry metallurgical machinery, lifting equipment, such as roller adjustment device; civil water projects with flood control and dam gate devices, bed lifts installations, bridges and other manipulation of institutions; speed turbine power plant installations, nuclear power plants, etc.; ship from the deck heavy machinery (winch), the bow doors, bulkhead valve, stern thruster, etc.; special antenna technology giant with control devices, measurement buoys, movements such as rotating stage; military-industrial control devices used in artillery, ship anti- rolling devices, aircraft simulation, aircraft retractable landing gear and rudder control devices and other devices.A complete hydraulic system consists of five parts, namely, power components, the implementation of components, control components, auxiliary components and hydraulic oil.The role of dynamic components of the original motive fluid into mechanical energy to the pressure that the hydraulic system of pumps, it is to power the entire hydraulic system. The structure of the form of hydra- ulic pump gears are generally pump, vane pump and piston pump.Implementation of components (such as hydraulic cylinders and hydraulic motors) which isthe pressure of the liquid can be converted to mechanical energy to drive the load for a straight line reciprocating movement or rotational movement.Control components (that is, the various hydraulic valves) in the hydraulic system to control and regulate the pressure of liquid, flow rate and direction. According to the different control functions, hydraulic pressure control valve can be divided into valves, flow control valves and directional control valve. Pressure control valves are divided into benefits flow valve (safety valve), pressure relief valve, sequence valve, pressure relays, etc.; flow control valves including throttle, adjusting the valves, flow diversion valve sets, etc.; directional control valve includes a one-way valve , one-way fluid control valve, shuttle valve, valve and so on. Under the control of different ways, can be divided into the hydraulic valve control switch valve, control valve and set the value of the ratio control valve.Auxiliary components, including fuel tanks, oil filters, tubing and pipe joints, seals, pressure gauge, oil level, such as oil dollars.Hydraulic oil in the hydraulic system is the work of the energy transfer medium, there are a variety of mineral oil, emulsion oil hydraulic molding Hop categories.The role of the hydraulic system is to help humanity work. Mainly by the implementation of components to rotate or pressure into a reciprocating motion.Hydraulic system and hydraulic power control signal is composed of two parts, the signal control of some parts of the hydraulic power used to drive the control valve movement.Part of the hydraulic power means that the circuit diagram used to show the differentfunctions of the interrelationship between components. Containing the source of hydraulic pump, hydraulic motor and auxiliary components; hydraulic control part contains a variety of control valves, used to control the flow of oil, pressure and direction; operative or hydraulic cylinder with hydraulic motors, according to the actual requirements of their choice.In the analysis and design of the actual task, the general block diagram shows the actual operation of equipment. Hollow arrow indicates the signal flow, while the solid arrows that energy flow.Basic hydraulic circuit of the action sequence - Control components (two four-way valve) and the spring to reset for the implementation of components (double-acting hydraulic cylinder), as well as the extending and retracting the relief valve opened and closed. For the implementation of components and control components, presentations are based on the corresponding circuit diagram symbols, it also introduced ready made circuit diagram symbols.Working principle of the system, you can turn on all circuits to code. If the first implementation of components numbered 0, the control components associated with the identifier is 1. Out with the implementation of components corresponding to the identifier for the even components, then retracting and implementation of components corresponding to the identifier for the odd components. Hydraulic circuit carried out not only to deal with numbers, but also to deal with the actual device ID, in order to detect system failures.DIN ISO1219-2 standard definition of the number of component composition, which includes the following four parts: device ID, circuit ID, component ID and component ID.The entire system if only one device, device number may be omitted.Practice, another way is to code all of the hydraulic system components for numbers at this time, components and component code should be consistent with the list of numbers. This method is particularly applicable to complex hydraulic control system, each control loop are the corresponding number with the systemWith mechanical transmission, electrical transmission compared to the hydraulic drive has the following advantages:1. a variety of hydraulic components can easily and flexibly to layout.2. light weight, small size, small inertia, fast response.3. to facilitate manipulation of control, enabling a wide range of stepless speed regulation (speed range of 2000:1).4. to achieve overload protection automatically.5. the general use of mineral oil as a working medium, the relative motion can be self-lubricating surface, long service life;6. it is easy to achieve linear motion .7. it is easy to achieve the automation of machines, when the joint control of the use of electro-hydraulic, not only can achieve a higher degree of process automation, and remote control can be achieved.The shortcomings of the hydraulic system:1. as a result of the resistance to fluid flow and leakage of the larger, so less efficient. If not handled properly, leakage is not only contaminated sites, but also may cause fire and explosion.2. vulnerable performance as a result of the impact of temperature change, it would be inappropriate in the high or low temperature conditions.3. the manufacture of precision hydraulic components require a higher, more expensive and hence the price.4. due to the leakage of liquid medium and the compressibility and can not be strictly the transmission ratio.5. hydraulic transmission is not easy to find out the reasons for failure; the use and maintenance requirements for a higher level of technology.In the hydraulic system and its system, the sealing device to prevent leakage of the work of media within and outside the dust and the intrusion of foreign bodies. Seals played the role of components, namely seals. Medium will result in leakage of waste, pollution and environmental machinery and even give rise to malfunctioning machinery and equipment for personal accident. Leakage within the hydraulic system will cause a sharp drop in volumetric efficiency, amounting to less than the required pressure, can not even work. Micro-invasive system of dust particles, can cause or exacerbate friction hydraulic component wear, and further lead to leakage.Therefore, seals and sealing device is an important hydraulic equipment components. The reliability of its work and life, is a measure of the hydraulic system an important indicator of good or bad. In addition to the closed space, are the use of seals, so that two adjacent coupling surface of the gap between the need to control the liquid can be sealed following the smallest gap. In the contact seal, pressed into self-seal-style and self-styled self-tight seal (ie, sealed lips) two.The three hydraulic system diseases1. as a result of heat transmission medium (hydraulic oil) in the flow velocity in various parts of the existence of different, resulting in the existence of a liquid within the internal friction of liquids and pipelines at the same time there is friction between the inner wall, which are a result of hydraulic the reasons for the oil temperature. Temperature will lead to increased internal and external leakage, reducing its mechanical efficiency. At the same time as a result of high temperature, hydraulic oil expansion will occur, resulting in increased com- pression, so that action can not be very good control of transmission. Solution: heat is the inherent characteristics of the hydraulic system, not only to minimize eradication. Use a good quality hydraulic oil, hydraulic piping arrangement should be avoided as far as possible the emergence of bend, the use of high-quality pipe and fittings, hydraulic valves, etc.2. the vibration of the vibration of the hydraulic system is also one of its malaise. As a result of hydraulic oil in the pipeline flow of high-speed impact and the control valve to open the closure of the impact of the process are the reasons for the vibration system. Strong vibration control action will cause the system to error, the system will also be some of the more sophisticated equipment error, resulting in system failures. Solutions: hydraulic pipe should be fixed to avoid sharp bends. To avoid frequent changes in flow direction, can not avoid damping measures should be doing a good job. The entire hydraulic system should have a good damping measures, while avoiding the external local oscillator on the system.3. the leakage of the hydraulic system leak into inside and outside the leakage. Leakagerefers to the process with the leak occurred in the system, such as hydraulic piston-cylinder on both sides of the leakage, the control valve spool and valve body, such as between the leakage. Although no internal leakage of hydra- ulic fluid loss, but due to leakage, the control of the established movements may be affected until the cause system failures. Outside means the occurrence of leakage in the system and the leakage between the external environment. Direct leakage of hydraulic oil into the environment, in addition to the system will affect the working environment, not enough pressure will cause the system to trigger a fault. Leakage into the environment of the hydraulic oil was also the danger of fire. Solution: the use of better quality seals to improve the machining accuracy of equipment.Another: the hydraulic system for the three diseases, it was summed up: "fever, with a father拉稀" (This is the summary of the northeast people). Hydraulic system for the lifts, excavators, pumping station, dynamic, crane, and so on large-scale industry, construction, factories, enterprises, as well as elevators, lifting platforms, Deng Axle industry and so on.Hydraulic components will be high-performance, high-quality, high reliability, the system sets the direction of development; to the low power, low noise, vibration, without leakage, as well as pollution control, water-based media applications to adapt to environmental requirements, such as the direction of development; the development of highly integrated high power density, intelligence, macaronis and micro-light mini-hydraulic components; active use of new techniques, new materials and electronics, sensing and other high-tech.---- Hydraulic coupling to high-speed high-power and integrated development of hydraulic transmission equipment, development of water hydraulic coupling medium speedand the field of automotive applications to develop hydraulic reducer, improve product reliability and working hours MTBF; hydraulic torque converter to the development of high-power products, parts and components to improve the manufacturing process technology to improve reliability, promote computer-aided technology, the development of hydraulic torque converter and power shift transmission technology supporting the use of ; Clutch fluid viscosity should increase the quality of products, the formation of bulk to the high-power and high-speed direction.Pneumatic Industry:---- Products to small size, light weight, low power consumption, integrated portfolio of development, the implementation of the various types of components, compact structure, high positioning accuracy of the direction of development; pneumatic components and electronic technology, to the intelligent direction of development; component performance to high-speed, high-frequency, high-response, high-life, high temp- erature, high voltage direction, commonly used oil-free lubrication, application of new technology, new technology and new materials.1.

The hydraulic pressure support development with first gazes [ Key word ] hydraulic pressure support; Control; Intellectualization1 hydraulic pressure supports developmentThe hydraulic pressure support is take the high-pressured liquid as a power, by certain hydraulic pressure part (cylinder, pipe accessory) one kind of strut and the control roof mining coal working surface equipment which becomes with some steel work combinations. Has the intensity high, the travelling speed quick, support the performance good, safe is reliable and so on the characteristic. Since the 20th century 50's, the hydraulic pressure support has gradually become the mining coal working surface core equipment, in the world mainly produced the coal country to invest the massive manpower physical resource and the financial resource carries on the research development to it. At present, support tends to take the hydraulic pressure support as the main body maturely, in the world has produced makes several hundred kind of frames and the up to ten thousand kind of models hydraulic pressure support, meets each kind of coal bed mining support need. On the century 60's, our country once has also developed 10 kind of hydraulic pressure supports, because all sorts of reasons have not obtained the promoted application, the hydraulic pressure support is in the development, the experimental stage; The 70's successively from England, Germany, Poland, former Soviet Union and so on mainly produce the coal country to introduce several 10 sets of hydraulic pressure supports. After the unceasing exploration, the use, the digestion and the summary, make each kind of type the support, it is the beginning which the domestically produced hydraulic pressure support develops; The 80's hydraulic pressure support research and development is in the innovation to enhance the stage, develops 30 kind of new frames one after another, makes the ZZ series, the XY series, the ZD series and so on the different specification, and widely uses in the state-owned large and middle scale coal mines, obtains the good economic efficiency; 90's special hydraulic pressure support development obtains the rapid development, the mechanized shop net support, the water granulated substance fills the support, the reason support, the force support, puts goes against thecoal support and so on to be published one after another; This century along with the computer technology, the automated technology popularization and the application, the hydraulic pressure support control obtains unprecedentedness to progress, gradually to the procedure control, the numerical control, the remote control and the automated control makes great strides forward.2 domestic and foreign hydraulic pressure supports differenceThe domestically produced support in the manufacture technology, the material quality performance, the processing craft, the control system and in the sealing property compares with the overseas advanced countries has the very big disparity. 2.1 processings manufactures aspectAccording to the related synthesis picks the engineers and technicians to reflect that, the domestically produced hydraulic pressure support craft technology, the service life, the operational performance, use the material quality so far not yet to achieve in 1979 introduced 100 sets of supports the technical levels. If structural material: Germany uses the ST52 material it yield strength is 500 MPa, but our country uses 16 Mn material yield strength is only 350 MPa; Valve class: Overseas always uses the copper alloy valve shell and the high strength stainless steel valve core, our country is the 45# steel adds surface heat processing; In processing craft: The overseas cylinder endophragm is duplicate plates, the domestic product for does not plate, causes the column premature to appear the spot in the use process, scratches and so on the seal leaks the fluid phenomenon, affects support the effect. The domestically produced hydraulic pressure support and the overseas production hydraulic pressure support compares the average to reduce 2 ~ 3 a service life.2.2 control systems aspectThe domestically produced hydraulic pressure support control system research and development is at backwardness condition, seriously restricted the support to move supposes the speed the enhancement and the synthesis picks the economic efficiency the display. In the world several mainly produce the coal great nation throughout to enhance the support control system achievement the synthesis to pick the economic efficiency the important method, the 20th century 60's use manuallystraight control the operating system; The 70's use the forerunner control system, along with it England first proposed the development electrohydraulic control system, the eighty's tends to maturely; The 90's ladders company develops the entire working surface electrohydraulic control system, follows closely after that Wister to cut down the advantage Asia - shell Switzerland special company to develop more advanced P - M3, P - the M4 electrohydraulic control system. Presently country and so on US, Germany, England, Australia basically all is the programmable electrohydraulic control, but our country still used the hand control system.2.3 hydraulic pressure parts aspectThe hydraulic pressure part research and development speed lags by far to the hydraulic pressure support need to develop. The hydraulic pressure support reliability mainly relies on the hydraulic pressure part reliability, the hydraulic pressure support in the coal mine production applies whether succeeds, the key lies in the hydraulic pressure part the technical performance whether does meet the requirements. Overseas at present uses the great current capacity safety valve, the fluid much controls the cone-way valve, the cut-off valve, initially supports the strength maintenance valve and the column quickly returns at once the fluid valve. To the hydraulic pressure part structural style, the geometry size, the choice of material, the heat treatment method and the surface treatment and so on various aspects have conducted the thorough research and the development. Develops one batch of sealing property well, the sensitivity high, enters the row of fluid ability to be big, the anti- impact load strong each kind of hydraulic pressure part, adapts the hydraulic pressure support operating performance request. But our country kind of hydraulic pressure part research and development lags regarding this, at present still continued to use the century for 80's the product, has not formed the hydraulic pressure part universalization, the seriation, the standardization3 hydraulic pressure supports prospects for development forecastIn view of the fact that the science and technology high speed development, new technical, the new craft, the new method, the new material unceasing application and the computer technology unprecedented expansion, the hydraulic pressure supportfuture development will have the extremely attractive prospect.3.1 designs ideas renewal, the hydraulic pressure support develops a revolutionMust consider the environment in the hydraulic pressure support design the attribute. Because the hydraulic pressure support working condition is bad, the person, machine the environment reciprocity question appears importantly. The green design is the choice of material, the product structure, the technique, the outward appearance modelling and the color matches according to the certain rule, adopts artistic the method to perform ingeniously to fuse, fully manifests the man-machine environment system the harmonious unification. The unwieldy hydraulic pressure support image safe, reliable, is been easy to service, lowly to consume energy, the high efficiency, the modelling artistic substitutes. This kind of green design, it not only Filtersthe environment and the resources both must meet the economical development needs, and must meet the human survival development needs, is the humanity sustainable developmental strategy in support design manifesting. For example: The hydraulic pressure support uses the multi- goals fuzzy design in the design process, requests to support the strength in a big way, moves a speed quickly, weight light, the timber wood are few and so on, each goal determined a function, namely many designs objective function, then the combination optimizes, determination preferred plan.3.2 will adopt the pure water hydraulic pressure technology, the hydraulic pressure support becomes the green machineryThe pure water hydraulic pressure technology is the hydraulic pressure domain development front. It not only has good anti- burns the nature, the radiation, moreover the price also cheaply, does not have the pollution, since the long-time hydraulic pressure support in Surfaceunder has worked, because the use actuating medium is the emulsion, and has many chemical additives (emulsifier, guards against rust medicinal preparation, antiseptic, partner mixture and so on), the micro environmental pollution is extremely serious to the surface below, therefore, the hydraulic pressure support use pure water hydraulic pressure technology, to reduces the coal mine the production cost, protects the environment is beneficial, and may greatly improve the mine pit the work and the security condition. Unceasingly progresses along with the society, the people had a higher request to the dependent survival environment, hoped has asecurity, the environmental protection, the highly civilized green environment. The time request summoned the hydraulic pressure transmission (to origin in 1605 discovered the Pascal's law) this ancient brand-new technology resurfaced, and received the world the attention. At present, the western nation concentrates the strength to study this technology, and makes the unprecedented progress. For example: The lubrication attrition question, reasonably selects rubs the vice- material, has the engineering plastics, the structure ceramics, the high polymer material, guards against rust anticorrosion coating and so on. The structure ceramics have the resistance to wear, the anti- cavitation performance is good, the good chemical stability, characteristic and so on lower friction factor, prepares is favoured. Replaces the partial metals material in the hydraulic pressure part with the structure ceramics, big improvement its performance. In brief, the new material success develops and applies, precisely processes technical the unceasing progress, as well as each kind of new structure hydraulic pressure part making, all will become the hydraulic pressure support to use the pure water hydraulic pressure technology to enter the strict non- pollution domain, will provide the extremely attractive application prospects for development.3.3 high tech applications, the hydraulic pressure support tends to the intellectualizationThe advanced science and technology application is mutually seeps each kind of technology, mutually unifies in the foundation mutually assists, mutually promotes and the enhancement, fully uses each kind of related technical the superiority, enhances strong points and avoid weaknesses, after causes the combination the overall function to be bigger than the composition whole sum of each part of function comprehensive interdisciplinary studies.. The many kinds of technologies unceasingly seep to "the mechanical parent substance - hydraulic pressure support", including technical and so on machine, electricity, fluid, light, magnetism servosystem. Specifically said that, is the strength, the speed which outputs by the hydraulic pressure support are a goal, constituted from has output to the input closed-loop system, was involves sensing the technology, the computer control technology, thesignal processing technology, the mechanical drive technology, the hydraulic transmission technology and so on. Because fast operating speed, formidable memory function and keen logical judgement function, thus has realized the man-machine dialogue, causes it operation maintenance conveniently, the entire machine function to be strong. The hydraulic pressure support application function unceasingly expands, unceasingly strengthens to the mine pit coal bed geology condition compatibility, production benefit to equipment dependent degree increasingly big, the operational reliability is more important. The breakdown diagnosis technology (including signal examination, breakdown judgement, failure detection, content and so on fault analysis) along with the high tech development theory (for example wavelet technology, nerve network, artificial intelligence and so on) will enter the hydraulic pressure support the early diagnosis, the prevention and the reduced accident occurrence, service blindness and the maintenance time, will lengthen the support service life, will enhance the production efficiency.4 concluding remarkIn summary, the hydraulic pressure support at present develops the main tendency is: Two columns shields type, enhances the hydraulic pressure support intensity, the design factor, moves a speed, the improvement individual part structure (overall top-beam, width center distance and so on), hydraulic pressure pipe accessory seriation, standardization, universalization, high working resistance, redundant reliability, with micro electron technology realization machine electrohydraulic integration digital gathering, operating mode monitor, breakdown diagnosis and automatic control.Hydraulic pressure support battery solution controlengineering research and applicationKey word:Hydraulic pressure support;Battery solution control system;Design applicationA coal mining technology significant innovation. At present,The battery solution control technology in synthesis and so on US, Germany picked the technical leadingcountry to obtain the widespread application,But our country then only then gradually the necessary use battery solution controls the technology in recent years on some hydraulic pressure supports1 battery solution control technology basic principle and main composition1.1 Battery solution control technology basic principle（1）Bidirectional neighbour control system.The synthesis picks working surface each support has the frame to control the box,The operator controls the box choice neighbour control mode through the support frame,Then sends out the corresponding control command according to the instruction (to produce electrical signal),Causes electro-magnet or micro electrical machinery movement which on neighbour corresponds,Let the electrical signal transform as the hydraulic pressure signal,Controls the host to control the valve to open,Supplies the fluid to the support hydraulic cylinder,Realization neighbour support corresponding movement. The support working mode active status feeds back the frame by the position transmitter and the pressure transmitter to control the box,The frame controls the box to decide the support again according to the sensor feedback signal the next movement.（2）Bidirectional becomes the group control system.Arranges the working surface support is certain groups,In on this group of in first frames presses the frame by the operator to control the box the start key,Sends out an instruction,Neighbour presses the pre-set sequence movement,After moves the frame to complete automatically sends out the control signal to control the box for next,Next starts the movement. Infer from this,In realization group support automatic control. （3）Entire working surface automatic control system.The function consummates battery solution.The control system is equipped with the main control console, the infrared installment,Can realize the support and the coal mining machine linkage entire working surface automation control. Its principle is:On each support frame controls the box with the main control console networking,Whenthe support infrared receiving device receives the position which the coal mining machine infrared launcher sends out to believe.After number,The feedback gives the main control console,The main control console sends out the instruction according to the feedback signal,Causes the corresponding support movement.1.2 Main constituent（1）Battery solution controller (SCU).The battery solution controller is a control system department.Series "heart",It by microprocessor, the intelligence transmission unit, operates the keyboard and the data receiving device and so on is composed. The battery solution controller has two aspects the functions:On the one hand is defers to the operational order and the pre-set sequence completes the solenoid valve group to open shuts,Then control support column, hoisting jack movement;On the other hand it receives the condition data which on the support obtains (including pressure, displacement and so on) and performs to analyze the judgment,Then controls the support the movement,And demonstrates the support state variable and the support breakdown.（2）Battery solution control valve group (FZ).The control valve group is one kind of multipurpose control hydraulic pressure solenoid valve,May replace the fluid cycle selector valve,This kind of valve assembly has causes the support movement the valve group and the surveillance support working condition pressure switch,Opens or the closed valve passage according to the controller instruction.（3）Central control bench (MCU).Whether the system does use MCU,Must the working surface automated horizontal height which determined according to the user decide. Only installs the battery solution controller,Even does not need to install the ground master control room (MCU1) and the mine shaft control room (MCU2),Also may realize the entire automation. The lowest level control system is a bidirectional neighbour unicontrol,What at present is commonly used is "as soon as controls four" the system,Then expands to the automatic arrangement, becomes the group to control, tobecome the group to pass and the combination function and so on,These all do not need the central control bench.（4）Periphery accessory.The battery solution control system has can surveyCondition, And transforms the hydraulic pressure parameter into the electronic signal original part pressure transmitter,The reflection passes the hoisting jack travelling schedule position contact sensor as well as uses for automatically to start the coal mining machine long-distance control hydraulic pressure support battery solution controller the infrared receiver and so on. All sensors all have respective output signal,Thus may discover the position which the line severs,And is distinguished by each support battery solution controller. If the system matches in the mine shaft working surface or the ground control room Has the central control bench,Has the breakdown cable line or the sensor can demonstrate on the key station screen,Like this very easy definite breakdown position battery solution control flow like chart 1 shows2 、battery solutions control the support the meritBelow this support and the hand control system compare has the merit（1）The support travelling speed is quick.At present the domestic hydraulic pressure support is es the hand control,It passes the speed besides to receive the system current capacity and the hydraulic pressure part has flowed the ability the limit,The worker also has the direct influence in the bay travelling speed to it,This kind of influence appears the outstandingly in the thin coal bed. The battery solution control support work process may automatically circulate carries on,Sped up moved a speed form eight to ten mintenuse,This speed can follow form13113 to 1315m/Min coal mining machine speed,Shan Taibeng current capacity 400 L/Min,Needs 2 to pump the simultaneous working. Satisfied the high efficiency coal mining machine fast to cut..（2）Improved the roof to support and protect the condition.Because uses to press every timeNiu operates,May enable the support to follow close on after the coal mining machine carries on supports andprotects,Moreover,Must act the support requests its two sides the support fastening to support and protect the roof,This characteristic and the correct strut unify,The guarantee forms a firm protecting band along the working surface.（3）Guaranteed the hydraulic pressure support fixed initially supports the strength.Battery solution control system.The passable excess pressure sensor feedback signal or lengthens the control electromagnetism the pilot valve on time realization at the beginning of support to support the strength self-preservation first. Guaranteed fixed initially supports the strength,Reduced the column to increase anti- needs the time,Enhanced has supported and protected the efficiency,Also the entire working surface at the beginning of support supports the strength evenly to be consistent,Improved the roof control（4）May have the pressure to move the frame.Uses the battery solution control system,Is moving the frame.In process,Easy to realize the belt pressure to move the frame,Reduced the working surface roof to have the frequent impact load to the hydraulic pressure support,Protection roof adjacent formation stability,Lengthens the hydraulic pressure support the service life.（5）Improved the working surface straight line.With manual operationcompared to,The overwhelming majority battery solution control support all is pusher type,This meant the conveyer pulls the phenomenon to be few,Causes all supports by the biggest displacement quantity to abut in a working surface conveyer armored cable side,Maintains a straight working surface. Moves a step of distance to be accurate,Cuts the crest line to be neat,Improved has supported and protected the effect,And causes the scraper conveyer and the entire working surface straight line. The nature is good,The coal mining machine truncation depth is accurate. Improved the scraper conveyer and the coal mining machine operating mode. Moreover at the same time the multi- frames pushes slides,Slowly causes the scraper conveyer to be curving,Avoids the chute attachment point having the oversized stress. （6）Improved the support operator's working condition.Battery solution controltechnical application,Has realized the hydraulic pressure support remote control operation,But indirect maintenance,The worker workcondition and the labor intensity have the enormous improvement,Because uses the computer automatic control,Reduced worker's misoperation.（7）The operation flexibility is big.Supports and protects the system the support operation sequence is very easy to change,May act according to the different mining condition,Is suitable specially for the thin coal bed and inclines anxiously the coal bed,Also may use in the drum coal mining machine working surface,Also may use in the coal plow working surface;Also may use in promptly supporting and protecting (moves first frame boosts slides) supports and protects the way,Also after may use in lags supports and protects (pushes first slides moves) supporting and protecting the way.（8）The system can realize the long-distance procedure control.The operator may the root.According to coal mining machine coal cutting choice of direction best position,Has avoided operator's casualty,At the same time also reduced the dust to the body the harm.（9）The battery solution control system may and the coal mining machine and the scraper conveyer.Automatic control system coordination linkage,Realizes the entire automated synthesis to pick the working surface. The support and the coal mining machine running status and the data may transmit to the tunnel in the main control console and the ground central control center,Is advantageous for the realization entire mine pit automated management.3、domestic and foreign development surveysAt present US, Germany and so on walk in this technology in the world front row,Its hydraulic pressure support battery solution control technology disposition has the breakdown to diagnose the early-warning installation,May realize the hydraulic pressure support and the coal mining machine, the scraper machine linkage and the long-distance control. Our country develops the hydraulic pressure support battery solution control system start to be late,Has developed successfully the first entire working surface hydraulic pressure support battery solution control system since 1995,Also has the many kinds of models the battery solution control system hydraulicpressure support to be published. But our country produces battery solution control system hydraulic pressure support also not in mine shaft promotion use,Many high production highly effective working surfaces use the battery solution control system hydraulic pressure support also to have from the overseas import. The support battery solution control system develops which from our country looked,Still was in Shan Jia and becomes the group procedure to control.System initial stage. In the system does not have the main control console,Support and coal mining machine linkage entire working surface automatic control system also in development stage. Zhengzhou coal mine mechanical group limited liability company in the last few years through and German DBT Corporation, emperor fragrance Bach company and so on cooperation,The overseas advanced battery solution valve the hydraulic pressure support which will produce with this company necessary,Takes the lead to put into the use in the Jincheng coal industry group,Has met the design requirements completely,Has coal industry group 6 syntheses successively and so on the Jincheng, god China picks working surface nearly 800.The battery solution control hydraulic pressure support already or was going to put into the use. ZY4400 /9 /21 thin coal bed coal plow working surface battery solution control hydraulic pressure support and the ZY8640 /2,515 /55 manufacture domestically picks the high shield type hydraulic pressure support through to have the product appraisal in pairs greatly which four Chinese Academy of Science academicians participates (appraisal),The appraisal thought these 2 kind of supports overall performance achieves the world advanced level. Moreover,Corporate design manufacture Chinese god China localization battery solution control hydraulic pressure.Support ZY7600 /22 /45/The world is highest 612 meter two columns shields type battery solution control hydraulic pressure support ZY9400 /28 /62 has all represented the domestically produced support maximum level,Achieved or approaches the world advanced level.Above two articles originate from Elsevier the ScienceDirect periodical液压支架的发展与前瞻[关键词] 液压支架; 控制; 智能化1液压支架发展概述液压支架是以高压液体为动力,由若干个液压元件(油缸、阀件)与一些金属构件组合而成的一种支撑和控制顶板的采煤工作面设备。

Hydraulic Station and the development ofhydraulic components ProfilesHydraulic Pump Station also known as the stations are independent hydraulic device.It requested by the oil gradually. And controlling the hydraulic oil flow direction, pressure and flow rate, applied to the mainframe and hydraulic devices separability of hydraulic machinery.Users will be provided after the purchase hydraulic station and host of implementing agencies (motor oil or fuel tanks) connected with tubing, Hydraulic machinery can be realized from these movements and the work cycle.Hydraulic pump station is installed, Manifold or valve combination, tanks, a combination of electrical boxes.Functional components :Pump device -- is equipped with motors and pumps, hydraulic station is the source of power. to mechanical energy into hydraulic oil pressure can be.Manifold -- from hydraulic valve body and channel assembled.

Which, hydraulic industry in the early 1950s from the machine tool industry production of fake Su-grinder, broaching machine, copying lathe, and other hydraulic drive started, Hydraulic Components from the plant hydraulic machine shop, self-occupied. After entering the 1960s, the application of hydraulic technology from the machine gradually extended to the agricultural machinery and mechanical engineering fields, attached to the original velocity of hydraulic shop some stand out as pieces of hydraulic professional production. To the late 1960s, early 1970s, with the development of mechanized production, especially in the second automobile factory in providing efficient, automated equipment, along with the Hydraulic Components manufacturing has experienced rapid development of the situation, a group of SMEs have become professional hydraulic parts factory.1968 China's annual output of hydraulic components have nearly 200,000 in 1973, machine tools, agricultural machinery, mechanical engineering industries, the production of hydraulic parts factory has been the professional development of more than 100 and an annual output more than one million. an independent hydraulic manufacturing industry has begun to take shape. Then, hydraulic pieces of fake products from the Soviet Union for the introduction of the product development and technical design combining the products to the pressure, Hypertension, and the development of the electro-hydraulic servo valves and systems, hydraulic application areas further expanded. Aerodynamic than the start of the industrial hydraulic years later, in 1967 began to establish professional pneumatic components factory, Pneumatic Components only as commodity production and sales. Sealed with rubber and plastics, mechanical seals and sealing flexible graphite sealing industry, the early 1950s from the production ordinary O-rings. rubber and plastics extrusion, such as oil seal sealing and seal asbestosproducts start to the early 1960s, begun production of mechanical seals and flexible graphite sealing products. 1970s, the burning of the former Ministry, a Ministry, the Ministry of Agricultural Mechanization System, a group of professional production plants have been established, and the official establishment of industries to seal industrial development has laid the foundation for growth.Since the 1980s, in the country's reform and opening up policy guidelines, with the development of the machinery industry, based mainframe pieces behind the conflicts have become increasingly prominent and attracted the attention of the relevant departments. To this end, the Ministry of the original one in 1982, formed the basis of common pieces of Industry, will be scattered in the original machine tools, agricultural machinery, mechanical engineering industries centralized hydraulic, pneumatic and seals specialized factories, placing them under common management infrastructure pieces Bureau, so that the industry in the planning, investment, technology and scientific research and development in areas such as infrastructure pieces Bureau of guidance and support. Since then entered a phase of rapid development, has introduced more than 60 items of advanced technology from abroad, including more than 40 items of hydraulic, pneumatic 7. After digestion and absorption and transformation, now have mass production, and industry-leading products. In recent years, the industry increased the technological transformation efforts, in 1991, Local enterprises and the self-financing total input of about 20 billion yuan, of which more than 1.6 billion yuan Hydraulic. Through technological transformation and technology research, and a number of major enterprises to further improve the level of technology, technique and equipment to be greatly improved. In order to form a higher starting point, specialization, and run production has laid a good foundation. In recent years, many countries in the development of common ownership guidelines, under different ownership SMEs rapid rise showing great vitality. With the further opening up, three-funded enterprises rapid development of industry standards for improving and expanding exports play an important role. Today, China has and the United States, Japan, Germany and other countries famous manufacturers joint ventures or wholly-owned by foreign manufacturers to establish a piston pump / motor, planetary reduction gears, steering gear, hydraulic control valve, hydraulic system, hydrostatic transmission, hydraulic Casting. pneumatic control valve, cylinder, gas processing triple pieces, mechanical seals, rubber and seal products more than 50 production enterprises, attracting foreign investment over 200 million U.S. dollars.Second, the current situation(1) Basic ProfilesAfter 40 years of efforts, China hydraulic, pneumatic and sealing industry has formed arelatively complete categories. a certain level of technical capacity and the industrial system. According to the 1995 Third National Industrial Census statistics, hydraulic, Pneumatic seals and industrial 370,000 annual sales income of 100 million yuan in state-owned, village-run, private and cooperative enterprises, individual, "three capital" enterprises with a total of more than 1,300, of which about 700 hydraulic, Pneumatic seals and the approximately 300 thousand. By 1996 with the international trade statistics, the total output value of China's industry hydraulic 2.348 billion yuan, accounting for the world's 6; Pneumatic industry output 419 million yuan, accounting for world No. 10.(2) the current supply and demand profilesThrough the introduction of technology, independent development and technological innovation, and high-pressure piston pump, gear pumps, vane pump, General Motors hydraulic valves, tanks, Non-lubricated aerodynamic pieces and various seals of the first large technology products has increased noticeably. stability of the mass production may, for various mainframe products provide a level of assurance. In addition, hydraulic and pneumatic components of the CAD system, pollution control, proportional servo technology has scored some achievements, and is already in production. Currently, hydraulic, pneumatic and seals products total about 3,000 species, more than 23,000 specifications. Among them, there are 1,200 hydraulic varieties, more than 10,000 specifications (including hydraulic products 60 varieties 500 specifications); Pneumatic are 1,350 varieties, more than 8,000 specifications; Rubber seal 350 species more than 5,000 specifications have been basically cater to the different types of mainframe products to the general needs, complete sets of equipment for major varieties of matching rate was over 60%, and started a small amount of exports.1998 pieces of homemade hydraulic output 4.8 million. sales of about 28 billion (of which about 70% mechanical systems); aerodynamic pieces yield 3.6 million. sales of about 5.5 billion (of which about 60% of mechanical systems); Seals output of about 800 million. sales of about 10 billion (of which about 50% mechanical systems). According to the China Hydraulic Pneumatic Seals Industry Association 1998 annual report, hydraulic product sales rate of 97. 5%, pneumatic 95.9%, 98.7% sealed. This fully reflects the basic marketing convergence.My hydraulic, pneumatic and sealing industry has attained a great deal of progress, but with mainframe development needs, and the world's advanced level, there are still many gaps, mainly reflected in the product variety, performance and reliability, and so on. Hydraulic products as an example, products abroad only one-third, life for half abroad. In order to meet key mainframe, and mainframe imports of major technology and equipment needs, every year a large number of hydraulic, pneumatic and sealing products imports. According to customs statistics and the analysis of data, in 1998 hydraulic, pneumatic and seals in the import about 200 million U.S. dollars, Hydraulic which about 1.4 billion dollars, aerodynamic nearly 030 million U.S. dollars, sealed about 030 million U.S. dollars. compared with a slight decline in 1997. By sums, currently imported products on the domestic market share of about 30%. 1998 pieces of the domestic market demand for hydraulic total of about six million, the total sales of nearly 40 billion; aerodynamic pieces of the total demand of about 5 million, with sales more than 700 million yuan; Seals total demand of about 1.1 billion. total sales of about 1.3 billion.Third, the development trend of the future1, affect the development of the main factors(1) product development ability, and the level of technological development and speed can notcompletely meet the advanced mainframe products, major equipment and technology imported equipment and maintenance support;(2) the number of enterprises manufacturing technology, the level of equipment and management standards are comparatively backward, coupled with a strong sense of quality, resulting in low levels of product performance, quality, Reliability poor services in a timely manner, lack of user satisfaction and trust of the brand-name products;(3) industry specialization of production low, scattered strength, low repeat serious, between regions and enterprises of convergence products, blindly compete with each other, driving down prices, the decline of enterprise returns, lack of funds, liquidity difficulties, product development and technological transformation is inadequate and seriously restricted the industry to improve the overall level of competition and the increase of strength;(4) The internationalization of the domestic market and the increasing degree of foreign companies have entered the Chinese market and participate in competition with the domestic private and cooperative enterprises, individuals, foreign-funded enterprises, such as the rise of state-owned enterprises due to the growing impact.2, the development trendAs the socialist market economy continues to deepen, hydraulic, pneumatic and sealing products in the market supply and demand and there is a greater change, long ago to a "shortage" of the seller's market has basically become a "structural surplus" of the characteristics of the buyer's market place . Overall capacity, is already in oversupply situation, in particular the general low level of hydraulic, pneumatic and seals, the general oversupply; and the host of urgent high-tech high-parameter, high value-added high-end products, and they do not satisfy the market needs, only dependent on imports. China joins the WTO, its impact may be even greater. Therefore, the "15" during the growth of the output value of industry, must not depend on volume growth and the industry should address the structural problems of their own, increase the intensity of the adjustment of the industrial structure and product mix, is, we should rely on the improvement of quality, and promote technical upgrading of products to meet market demand and stimulating, seek greater development.CALLS西文期刊目次数据网液压站及液压元件的发展概况液压站又称液压泵站，是独立的液压设备。

中文3840字英文原文Powered supportsPowered roof supports are used to support the roof at the face.They work in several steps mostly in the immediate forward support (IFS) type in order to support the newly exposed roof as soon as possible. In normal supporting condition the canopy of the support is set tightly against the roof strata,by the supporting resistances of the hydraulic legs. When the cutting machine cuts and passes several support units beyond the support in question, the support legs are lowered and pulled forward for a distance equal to the width of cut (web) by retracting the hydraulic advancing ram. The advancing ram acts against the face conveyor panline, whose position is held unchanged by the advancing rams, forces of the supports that are set on both sides of the support to be advanced. As soon as the support has been advanced to the designed position, the support is immediately reset against the roof. Finally, the advancing ram of the support in question is extended to push the conveyor forward and becomes ready for the next cut.The sequential steps described are for the advance of an individual support in the direction perpendicular to the faceline.But along the faceline direction, the conveyor cannot be advanced in a sharp step immediately after the shearer has passed it, due to the rigidity of the panline. Thus the fourth step is usually sometime after the shearer,s pass, resulting in a curved or snaked section.During panel development the panel entries are roof bolted as usual. But in the tailentry one or two rows of cribs are erected to supplement the roof bolting. During retreating mining, the roof at the headentry T-junction area (up to 500 ft (152m) outby the face) is generally reinforced with supports of some type to increase support density to cope with the moving front and side abutment pressures.Modern longwall mining employs hydraulic powered supports at the face area. The supports not only holds up the roof, pushes the face chain conveyor(AFC), and advances itself, but also provides a safe environment for all associated mining activities. Therefore its successful selection and application are the prerequisite for successful longwall mining. Furthermore, due to the large number of units required, the capital invested for the power support usually accounts for more than half of the initial capital for a longwall face. Therefore both from technical and economic points of view, the powered support is a very important piece of equipment in a longwall face.Classification of powered supportsThe application of modern powered supports can be traced back to early 1950s. Since then, following its adoption in every part of the world, there have been countless models design and manufactured in various countries. But unfortunately, there still is no uniform system of classification.In this section a simplified classification is used. Since a powered support consists of four major components (i. e , canopy, caving shield, hydraulic legs and props, and base plate), the ways by which they are interrelated are used for classification. In this respect, two factors are most important: (a) presence or absence of caving shield- if a caving shield is included, the support is a “shield” type, otherwise, a frame or a chock; (b) number and type of arranging the hydraulic legs- since support capacity is generally proportional to number of hydraulic legs, it is important to specify the number of hydraulic legs that a support has. Furthermore, the way the hydraulic legs are installed is important; for example, a vertical installation between the base and the canopy has the caving shield has the least efficiency in supporting the roof.Based on this concept, there are four types of powered support, that is, the frame, chock, shield and chock shield, in order of evolution of their development. However, it must be noted that the trend of development in each type is such that it becomes less distinguishable in terms of application.The four types of roof supports can be obtained for either longwall retreating or advancing systems, and they are available in standard, one-web-back, and immediate forward support (IFS) versions.With the standard system, the wining machine takes a cut or a slice, and the armored face conveyor is pushed over by the hydraulic rams that are fixed to the support units. The support units then are advanced sequentially to the conveyor. With the one-web-back system, a support is set back from the conveyor by a device that automatically keeps the leading edge of the support at a fix distance from the conveyor. This allows easy access though the face and employs the standard method of advancing; i. e , pushing the conveyor first, and then advancing the support.With the IFS system, the support units is advanced to the conveyor immediately after the cutting machine has passed, and the forward canopy of the support units is long enough to the support both the recently and newly exposed roof sections. After the supports have been advanced, the conveyor is pushed over.FrameThe frame support is an extension of the single hydraulic props conventionally used underground. Thus it is the first type developed in modern self-advancing hydraulic powered supports. It involves setting up two hydraulic props or legs vertically in tandemthat are connected at the top by a single or two segmented canopies. The two segmented canopies can be hinge-jointed at any point between the legs or in front of the front leg. The base of the two hydraulic legs may be a circular steel shoe welded at bottom of each leg or solid base connecting both legs.Generally, a frame support consists of two or three sets of hydraulic legs. The set moving first is the secondary set, the set moving later is the primary set. There is a double-acting ram installed between each set. The piston of the ram is connected to the secondary set and the cylinder to the primary set. During support advance, the primary set is set against the roof while the secondary set is lowered and pushed forward by the piston. Having reached the new position, the secondary set is against the roof while the primary set is lowered and pulled forward by the cylinder. The distance of each advance ranges from 20 to 36 in.(0.50 ~ 0.91m)The frame support is very simple, but more flexible or less stable structurally. There are considerable uncovered spaces between the two pieces of canopy which allows broken roof rock to fall through. Consequently, the frame support is not suitable for a weak roof. Frames have become seldom used because they are less stable and require frequent maintenance.ChockIn a chock support, the canopy is a solid piece and the base may be either a solid or piece or two separate parts connected by steel bars at the rear and/or thefront ends. In both cases a large open space is left at the center for locating the double-acting hydraulic ram which is used to push and pull the chain conveyor and the chock in a whole unit, respectively, a distinctive difference from the frame support. This setup is also used in the shields and chock shields.Again, all hydraulic legs are installed vertically between the base and the canopy. The number of legs ranges from three to six, but the four-leg chocks are by far the most popular ones. The six-leg chocks are designed for thin seams with two legs in the front and four legs in the rear, separated by a walkway. For the six-leg chocks, the canopy is generally hinge-jointed above the walkway. Most chock are also equipped with a gob window hanging at the rear end of the canopy. The gob window consists of several rectangular steel plates connected horizontally at both ends.In most chock supports, there are hinge joint connections between the legs and the canopy and between the legs and the base. But in order to increase the longitudinal stability, it is reinforced mostly with a box-shaped steel frame between the base and each leg. A leg restoring device is installed around each leg at the top of the box-shaped steel frame.The chocks are suitable for medium to hard roof. When the roof overhangs well into the gob and requires induced caving, the chocks can provide access to the gob.ShieldShields, a new entry in the early seventies, are characterized by the addition of a caving shield at the rear end between the base and the canopy. The caving shields, which in general are inclined, are hinge-jointed to the canopy and the base making the shield a kinematically stable support, a major advantage over the frames and the chocks. It also completely seals off the gob and prevents rock debris from getting into the face side of the support. Thus the shield-supported face is generally clean.The hydraulic legs in the shields are generally inclined to provide more open space for traffic. Because the canopy, caving shield, and base are interconnected, it can well resist the horizontal force without bending the legs. Thus, unlike the solid constraint in the frame/ chock supports, the pin connections between the legs and the canopy , and between the legs and the base in a shield support make it possible that the angle of inclination of the hydraulic legs varies with the mining heights. Since only the vertical component of hydraulic leg pressure is available for supporting the roof, the actual loading capacity of the shield also varies with the mining heights.There are many variations of the shield supports. In the following, six items are used to classify the shields , which enables a unified terminology to be developed for all kinds of shields. The types of motional traces of the canopy tip, leg positions and orientation, number of legs, canopy geometry, and other optional designs and devices can be clearly specified by the terminology .Types of motional traces for the leading edge of the canopy.This is the most commonly recognized way of classifying the shield. Based on this criterion, there are three types, lemniscate, caliper , and ellipse.Lemniscate. This is the most popular type. The caving shield and the base are jointed by two lemniscate bars which have a total of four hinges. As the hydraulic legs are raised and lowered, the dimentions of the lemniscate bars are selected such that the leading edge of the canopy moves up and down nearly vertically , thus maintaining a nearly constant unsupported distance between the face-line and the leading edge of the canopy .This is a feature that is widely considered most desirable for good roof control . There are clear limits of mining height within which the leading edge of the canopy moves nearly vertically. These limits are strictly controlled by the dimentional and positional arrangements of the canopy, caving shield, lemniscate bars, and the base. Beyond these limits, the edges will move rapidly away from the face-line creating a large unsupported area.Caliper. In a caliper shield, the caving shield and the base are connected by a single hinge .When the hydraulic legs are raised, the leading edge of the canopy moves in an arc away from the face, thus increasing the unsupported area. This is considered by most users the least desirable feature of the caliper shield .But in practice if the seam thickness varies little, the dimentional and positional arrangement of canopy, caving shield, and the base can be so designed that the distance change of unsupported area will not be significant. On the other hand, when the legs are lowered, it reduces the unsupported area.Ellipse. In this type the caving shield and the base are so connected that when the hydraulic legs are moved up and down, the leading edge of the canopy follows an elliptical trace. This type is seldom used.Chock shieldThe chock shield combines the features of the chocks and the shields. As such it possesses the advantages of both.If all of the four or six legs are installed between the canopy and the base, it is called a chock shield. There are regular four or six-leg chock shields in which all legs are vertical and parallel. Others form V or X shapes. Some canopies are a single piece and some are two pieces with a hydraulic ram at the hinge joint. The chock shield has the highest supporting efficiency. They are suitable for hard roof.Common elements of powered support sThe modern powerd supports, regardless of the types ,consist of the following five common components:( 1 ) Load-bearing units. These include the canopy, base plate, caving shield, lemniscate bars, and joint pins.( 2 ) Hydraulic rams. These include the hydraulic rams for ( a ) pushing the chain conveyor and advancing the powered support, ( b ) operating the front canopy or face guards, ( c ) balancing or limiting the position of the canopy, and ( d ) operating other auxiliary equipment such as leg recovering devices and side shideds, and above all, operating the legs.( 3 ) Control and operating Units. These include internal control valves such as check and yield valves in the hydraulic legs, unit control valve, and high pressure hydraulic tubings.( 4 ) Auxiliary devices. These include support advancing,leg recovering, gob windows, face guards, base-lifting, lighting, and so on.( 5 ) Hydraulic fluid. This is the emulsion for operating the powered supports.中文译文液压支架液压支架被用来支护工作面顶板。

PrefaceAs the important pillar industry of national economy rapid growth in China, the industrialization process of petrochemical industry has been constantly intensified with continuous and rapid development* Chen sining. Tel.: +086-010-********; fax:+086-010-********. E-mail address : chensn@;.1877-7058 © 2011 Published by Elsevier Ltd.doi:10.1016/j.proeng.2011.08.89915 48182 Chen Chen sining sining/ Procedia Engineering (2011) 4814000–000 4815 of national economy, so that the production of dangerous chemicals has been constantly increased, thescale of production has been increasingly enlarged, and hence the production and storage device has been increasingly large-scale to constitute more and more major dangerous sources due to more and moredangerous chemical devices with high energy and high toxicity.The occurrence and development of science has been determined by the production since thebeginning. Without exception of the development of dangerous chemical intrinsically safety, it has beengradually established and developed in recent decades with the industry development needs of high-riskindustries such as petrochemical industry.On the basis of the existing intrinsically safety technology research in both home and abroad, a numberof research institutions and device manufacturers has conducted studies for inherent explosion-proofsafety technology solutions and relevant equipment design for oil storage and transportation device,including the research and development of novel explosion-proof material and device, probe on theprocessing skills and installation technology for novel materials, proposal of installation technologystandard and construction specification for novel explosion-proof device, so as to provide the basis andsolutions for the storage safety of the inflammable and explosive liquid (gas) dangerous chemicals. These extensive studies, aiming at the intrinsically safety of inflammable and explosive dangerous chemicalsduring storage, have been conducted to build a safe and convenient space for national production andsocial activities in this field[1-5].2. Mechanism research on explosion-proof technologyBroadly speaking, the explosion-proof technology is to use the explosion-proof device to block theflame or explosion inside the equipment regarding the danger during oil storage & transportation andusage, so that it has no way to spread or disperse to other devices through pipes. The explosion-prooftechnology has been widely used in various fields of production and life such as mining, chemical,machinery and power, for example, prevention of mine gas explosion, fire-proof and explosion-proof foroil pipe and oil storage, prevention of food dust explosion, pipe network explosion-proof for inflammablegas in furnace, explosion-proof for combustion engine exhaust system and so on. According to thedifferent mechanism of explosion-proof technologies, they may be divided into such two kinds asmechanical explosion-proof and chemical explosion-proof technology; the explosion-proof device mayalso be divided into many kinds such as industrial flame arrester, active explosion-proof device andpassive explosion-proof. Therefore, the coverage of the explosion-proof technology in broadly speakingis various.However, the explosion-proof technology discussed in this paper refers to the proprietary technology toprevent the oil storage devices such as oil (gas) station, oil (gas) truck, oil (gas) tank and oil depot fromfire or explosion disasters; this technology is to fill or install the mesh or honeycomb metal (non-metal)material inside or outside the devices such as oil tank, oil storage and refueling truck of transportmachines (plane, automobile, ship, etc.).The explosion-proof technology is to utilize special material with honeycomb structure of high porosityto block rapid dispersion of flame and abrupt release of energy according to heat transfer theory as well asthe basic conditions to cause combustion or explosion; this technology utilizes the surface effect ofmaterial to absorb large amounts of energy, which destroys the explosion condition for combustionmedia, so as to block the occurrence of combustion or explosion; it can effectively prevent the storagecontainer and device for inflammable and explosive gas or liquid dangerous chemicals from combustionor explosion due to accidents (such as open fire, electrostatic, welding, shooting, collision, mistakenoperation, etc.), so as to ensure the intrinsically safety for the inflammable and explosive gas or liquiddangerous chemicals during storage and transport.Chin sining/ Procedia Engineering 00 (2011) 000–000– 48184816 Chen sining / Procedia Engineering 15 (2011) 4814 3 The explosion-proof mechanism of blocking explosion-proof technology may be separated into suchtwo parts as physical mechanism and chemical mechanism; the physical mechanism includes flameretarded effect and heat transfer effect, while the chemical mechanism includes the wall effect andcooling effect.2.1. Physical mechanism(1) Flame retarded effect:The flame propagation of inflammable media is very similar to the law of fluid flow. The flamedisperses all around according to certain speed of propagation and it is the resistance of propagation toinfluence the speed of propagation. The explosion-proof material has highly porous structure so the poresof material can decompose the propagation energy of flame, and simultaneously, the highly porousstructure can greatly increase the resistance of flame propagation, therefore, the pore size has decided the resistance of flame propagation and speed of propagation. Larger pore size means faster speed ofpropagation and smaller pore size means slower speed of propagation, so the flame propagation may bestopped when the pore size is decreased to certain limit. This flame flow explosion-proof porous blockingeffect is called as the blocking effect of material, which can directly influence the explosion-proof effectof material.(2) Heat transfer effect:Inside the container of oil storage and transportation, the inflammable gas or vapor mixes with air toform combustion and explosion space, where is filled with blocking explosion-proof material. When the concentration of mixed gases is within the explosion limit, combustion will occur in case of open fire; theflame produces great heat during propagation, due to the superior heat transfer and surface effect ofexplosion-proof material, the energy is rapidly absorbed and dispersed by the material with large specificsurface area, which can destroy the explosion condition of combustion media, therefore, the flameintensity decreases during propagation and the energy also decreases until extinguished.2.2.Chemical mechanism(1) Wall effectMixed explosion is radical chain reaction. The reaction speed is restricted by the number of radicals inunit volume, whereas the free radicals can be absorbed by the wall surface impurities and wall materials,and thi s kind of “wall absorption” has decreased the number of radicals in unit volume, if larger thesurface area, more chances of being absorbed, therefore, the less of the number of radicals in unit volume.Since the number of radicals contributing to combustion is decreased, the combustion and explosionspeed has been controlled until the reaction is interrupted.According to chain reaction theory, during chain explosion, the active center of chain reaction spreadsto the surrounding space until wall surface and extinct at wall surface. The wall surface extinct number ofchain is dependent upon effective number of collision, which is related to the shape of collision wall,because the collision wall with different shape has different effective collision factor K.Rectangular: K＝12D／d2Cylindrical: K＝23D／d2Spherical: K：40D／d2Wherein, d is the shell diameter; D is the dispersion factor. The spherical outer wall reflects larger pressure.Therefore, the unique hexagonal honeycomb structure is selected for the blocking explosion-proof material, which greatly increases the collision number of chain and hence realizes the purposes of anti- explosion.(2) Cooling effectThe heat produced by combustion can further improve the reaction temperature and accelerate the reaction speed until the explosion occurs. However, the superior heat conductivity of metal blocking explosion-proof material has the heat dispersion and cooling effect, which has controlled the temperature rise and acceleration of reaction speed within the combustion and explosion space, and hence restricted the occurrence of explosion.3. Current research focuses and research method3.1. Research on novel explosion-proof materialThe explosion-proof material is the explosion-proof body with mesh highly porous structure developed according to the explosion-proof mechanism of blocking explosion-proof technology, used in solving the intrinsically safety of inflammable and explosive liquid (gas) dangerous chemicals during storage. The explosion-proof material is the carrier of explosion-proof technology, which is the most direct form to reflect it. There are three hot topics in this research field, including:(1) According to the characteristics of existing oil products and the operation conditions of storage & transportation device, the relevant performance indexes for the explosion-proof material have been determined;(2) The substrate for the explosion-proof material has been screened to develop novel explosion-proof material regarding different oil products such as regular gas, methanol gas and jet fuel.(3) Research on the processing technology of novel explosion-proof material.3.2.Research on explosion-proof reforming technology based on existing oil storage deviceBecause most of the storage tanks in internal oil (gas) stations are buried, there are large amounts of fuel media preserved in the tank, and the reasons to result in combustion or explosion accidents include:(1) Outside of the storage tank on fire causes the combustion or explosion of storage tank itself;(2) Explosion of empty or “half-empty” storage tank due to electrostatic;(3) Combustion or explosion due to accidental trench leakage of oil transmission pipe;(4) The buried storage tank is arranged in underground tank pool (the tank pool is concrete pool in general). In the tank pool is filled with sand so that there is no combustion or explosion space between the tank pool and tank body, which has the explosion-proof effect. In practical construction, however, it is often not operated according to the specification. Therefore, the potential safety hazard of buried storage tank is very outstanding, in spite of the safety management of gas station and strict regulations on the surrounding environment, which can ensure to some degree the decrease in the occurrence of safety accidents. However, only the reformation of storage tank itself may realize the intrinsically safety, so as to fundamentally eliminate such accidents as explosion of storage tank.Thus, it is necessary to research the explosion-proof technology reforming scheme and installation technology for typical oil storage devices such as gas station buried storage tank and refueling truckChin sining/ Procedia Engineering 00 (2011) 000–000– 4818Chen sining / Procedia Engineering 15 (2011) 4814 5 storage tank, as well as the implementation process of explosion-proof technology reforming for typicaloil storage devices.4. ConclusionWith the increasingly mature existing technology of the explosion-proof technology as well as thepromotion of a series of new achievements, the implementation and application of explosion-prooftechnology has also been greatly promoted. At present, the explosion-proof technology has begunpromotion and application in many fields such as gas station buried storage tank, oil (gas) truck, large oil(gas) depot or spherical tank. The oil products involve gasoline, diesel, and methanol gasoline, all overthe country.With the rapid growth of petrochemical industry, on the one hand, the application field of explosion-proof material will be wider and wider and the scale will be larger and larger; on the other hand, thetechnical development of the users of the explosion-proof material in oil, chemical and dangerouschemical industry have proposed higher requirements of technology, quality and variety for theexplosion-proof material, which has promoted the research and development of novel high qualitymaterial, from single explosion-proof material developing to safe, green, environmental, longevity andenergy-saving multifunctional material.AcknowledgmentThis study was supported by the National Natural Science Foundation of China (No. 50804042).References[1]J.

外文资料Development Status and Trend of Hydraulic Press1 PrefaceWith the progress and development of nearly 50 years of science and technology, hydraulic technology has become a modern machinery and equipment technology of the important basic subject and basic technology, hydraulic machine is a by liquid pressure to transmit energy, to achieve the various processing of machine tools. With the application of new technology and new technology, the application of hydraulic press in metal forming and non metal forming is more and more widely.2 Application areas of hydraulic pressHydraulic press is suitable for almost all process of pressure processing. At present, the main application of hydraulic machine in the following areas: 1. Deep drawing sheet metal forming technology, mainly used in forming automobile and home appliances industries metal cover; the metal parts forming, mainly including pressure molding, metal profiles extrusion, cold forging, hot forging process and free powder; products such as magnetic materials, powder metallurgy etc.; the non pressed metal material forming, such as SMC molding, automotive interior parts molding and rubber products; hot pressing the wood products, such as hot pressing processing plant fiber board materials, profiles; the other applications such as pressing, correction, plastic, stamping process.3 Main structural forms of hydraulic pressAccording to the form of the structure classification, hydraulic machine mainly includes single column hydraulic press, four column hydraulic machine, frame type hydraulic machine and other structures of the hydraulic machine. Single column hydraulic machine can be divided into two structures of whole body and combined frame, single column hydraulic machine at work, due to the deformation of the body and the slide block and the work bench will produce a certain angle, so they are usedin applications to the precision request is not high, such as: pressing, plank pressure type, straightening technology [3]. Four column to beam connected by the four column hydraulic machine, and the slider of the activity crossbeam rely on four column guiding, the machine has has the advantages of simple structure, low manufacture cost etc..Therefore, the most widely used. Welded frame column instead of cylindrical column four column hydraulic machine for frame type hydraulic press, the slider guide rely on to guide with high accuracy, advantages of anti partial loading capacity is large, but the manufacturing cost is higher than the four column hydraulic machine guide rail fixed on the upright post conducting. In many higher requirements on accuracy of occasions, such as sheet metal stamping, precision metal forming process. The above three kinds of hydraulic machines accounted for more than 95% of the total number of hydraulic press. According to different needs, in addition to all other special structure of the hydraulic machine, such as: multi column, multi type, horizontal, gantry type structure of the hydraulic machine.4 Current situation of domestic hydraulic machine industry4.1 In production capacity and market, domestic hydraulic machine, the annual output has great growth rate, which in 2004, sales of domestic hydraulic machine about in 10 billion yuan, in 2005 reached 1.3 billion, the first quarter of 2006, the hydraulic press production enterprises of the annual orders has been basically saturated. In 2006, sales revenue, domestic breakthrough billion yuan enterprises have more than three, such as Hefei Metalforming Machine Tools Co., Ltd., Tianjin day forging press Co., Ltd., Xuzhou pressure Machinery Co., Ltd., which Hefei Metalforming Machine Tools Co., Ltd., Tianjin day forging press Co., Ltd. in 2005 sales revenue has exceeded 200 million yuan. Comparison of domestic hydraulic machine from the output value and sales income and foreign developed countries, also does not have the advantage, but from the production units and total tonnage compared in international, our country hydraulic machine production in leading position. Domestic hydraulic machine in the domestic market share of more than 90%, the output value of exports accounted for less than of the total output value, less than5%, only a small number of enterprises have export conditions, mostly exported to the third world countries. Domestic imports of hydraulic machines for some special hydraulic machines, most of the Japanese products, European and American products less.4.2 On the technical level of the product, the technical level of the domestic hydraulic press has reached the international medium or advanced level. Some hydraulic machine production enterprises through the introduction of technology or cooperation with the domestic and foreign industry, technology development is very fast. But in some high technology content of the hydraulic machine. Some key technologies, such as hydraulic and electric control parts, but also through cooperation with domestic and foreign enterprises or research institutes, high-end hydraulic components and electronic components also rely mainly on imports. At present,domestic hydraulic machine product or as a stand-alone or stand-alone consisting of unrelatedproduction line, mainly rely on artificial material, with automatic feeding hydraulic machine units is less than 3%, consisting of multiple machines, automatic line basically is still in initial stage. From the point of view of product distribution, low hydraulic machine mainly concentrated in the small tonnage, the units possession of more than 70% of the total but the value does not exceed 30%, generally small tonnage column or single column hydraulic machine. With certain technical content of mid-range frame type hydraulic machine output more than 50% for special occasions of quite advanced in the control of high-grade products output share about at around 15%, this kind of hydraulic machine generally use the advanced electro-hydraulic proportional technology, to improve and achieve certain special functions.4.3 In the quality level, with the continuous improvement of product quality requirements, the domestic various hydraulic machine manufacturers pay more and more attention to the quality of products. Because the technology of domestic hydraulic press is the first time that the Soviet Union was introduced and absorbed,the domestic production of hydraulic press is far superior to the products of Japan and South Korea in the rigidity and strength, and the products are quite. And foreign products compared our products in terms of quality still exist the following problems: in terms of reliability, failure rate is still relatively large, mainly concentrated in the hydraulic system, mostly because of hydraulic and electrical components of the low reliability caused by; II the problem of oil leakage is more common in domestic hydraulic machine; and the processing quality of 3 key parts still need to improve; (4) in appearance and aesthetic aspects and a foreign company's products comparison and certain gap. Generally speaking, domestic hydraulic machine in quality and some of the more well-known company's products and certain gap, but with the improvement of domestic manufacturers of quality continuous attention and management level, the quality of domestic hydraulic machine will close to and catch up with international level.5 development direction and trend of hydraulic press5.1 Equipped with automatic feeding device of the hydraulic press or automatic production line will be the future direction of the development of hydraulic press. At this stage, due to the cost of labor and technical problems, domestic enterprises to use artificial up and down. But in some developed countries, in the last century sixty or seventy's automatic production line has been basically popularized. In order to enhance the image of enterprises and improve production efficiency, and now the domestic enterprises have begun to use and procurement of automatic production line and automatic up and down material of the hydraulic press. Some enterprisesalso began in the raw material on the production line of the hydraulic machine and the transformation of the robotSemi automatic production line.5.2 The demand for hydraulic machines will be greatly increased. Due to processing equipment, technology and other reasons, the domestic multi position hydraulic machine is not a lot of. Multi station hydraulic machine has many advantages: multi-channel processes in a hydraulic machine in different stationcompleted, reducing the hydraulic units, thereby reducing the occupied area of equipment; (2) reduce the equipment to send material procedure and operating personnel; (3) to improve the production efficiency; and (4) to reduce the investment cost. Now some large hydraulic machine production enterprises in the processing and technology has been equipped with a multi station hydraulic machine design and production capacity. Over the next ten years, the domestic multi station hydraulic machine will be widely used in certain industries. In the United States, there are 70% stamping lines for multi station press, Japan's press line in the multi station press also accounted for 32% of the number of bus, and in the domestic stamping line almost no multi station press.5.3 Fast, high speed hydraulic machine in mass production can be multiplied to improve efficiency. If the hydraulic machine can improve the efficiency of one times, then a production line can replace two production lines, in the case of a small increase in the user's investment can be replaced by a line of two lines. General general hydraulic machine and the speed of the return speed of only 100~200mm/s, and now the rapid hydraulic press has been as high as 450mm/s. Some foreign high-speed and small hydraulic presses every minute of the number of strokes to reach hundreds of times. Due to the birth of rapid hydraulic press, 2000 years after the new automobile press line adopts hydraulic proportion has reached more than 60%, and in the 1990s before the automobile press line, almost all the mechanical press. There is a great potential to improve the speed and efficiency of the hydraulic machine, the manufacturer should be to strengthen research and development in this area, in conjunction with automatic feeding device based on, to achieve efficient work.5.4 Relying on electro hydraulic proportional technology, sensors, electronic, computer, network, etc. to improve the performance of hydraulic press. Rapid development since the last century 80s electro hydraulic proportional components, the application of proportional valve and proportional pump in the hydraulic machine make the function of the hydraulic press can through the electric to control the hydraulic press hydraulic control system has undergone a qualitative change, proportional pressure, proportional speed control, synchronization, energysaving, high speed, variable pressure and speed, accurate pressure and position control functionsbegan to be used in some high-end hydraulic machine. In the electronic control using the powerful function of computer and network, combined with microelectronics technology, with the combination of electro-hydraulic proportional technology and electronic hydraulic technology and computer, improve both to expand the function of hydraulic machine, the performance of the hydraulic machine, do without changing the hardware. Only through changing the program or software, can adapt to different process requirements, to achieve the function of flexible. In addition, the network technology can be used in equipment management, the hydraulic machine as a node in the network to achieve remote management, monitoring and other functions.5.5 In environmental protection, energy saving, in the future in the design and manufacture of hydraulic machines should be paid enough attention to the manufacturing enterprises. This aspect should do the following: 1. Reduce the power of the hydraulic press and reduce the energy loss in the work. In the hydraulic system, as far as possible to reduce the overflow, throttle, reasonable design of hydraulic system. For example a rely on relief valve overflow protection pressure hydraulic machine consumption of energy may be closed pump protection 2 times the pressure of the hydraulic machine, rely on energy storage device to improve the no-load speed of the system at least two times higher than that of the fast cylinder system is a waste of energy above. Improve the sealing quality, reduce the pollution of hydraulic oil leakage to the environment. Reduce noise, to isolate and close the large noise source.6 Needs to be improved.Domestic hydraulic machinery industry in the development of the need to strengthen domestic hydraulic press technology and production capacity has gradually become mature, in the domestic market share reached 90% and has begun to export to some developed countries. But the hydraulic machine industry in the development of the future, still need to work hard, in particular, to do the following:6.1 To strengthen enterprise technology research and development capabilities, toenhance the ability of new product development. Machine tool industry in the high-end competition in largely depends on the technological content of products, hydraulic machine industry in China to want to occupy the world in the high-end market, must first be in the technology reached the international advanced level, domestic set up a special hydraulic machine research institutions and personnel, in order to improve the level of the integrated technology of hydraulic machine.6.2 To strengthen joint between enterprises, the main production enterprises, automatic feedmaterial enterprises, research institutes, coalition, play to their respective advantages, mutualdevelopment and take complete sets of automatic production line project, solve the interrelated technology.6.3 Improve the quality of products, to provide high reliability of products. In the hydraulic system reliability, installation quality, processing quality, oil leakage, the cleaning of hydraulic oil to improve, in order to adapt to the automatic line, production line.7 Four column hydraulic machineHydraulic machine or hydraulic machine, is the use of liquid pressure transmission machinery by using Pascal's law made many kinds of. Of course, use is also based on the needs of a variety of. If the liquid type according to the transfer pressure, there are two types of oil press and hydraulic press. The hydraulic press machine has a large total pressure, commonly used in forging and stamping. Forging hydraulic press is divided into two kinds of forging hydraulic press and free forging hydraulic press. Die forging hydraulic press to use the mold, and free forging hydraulic press without mold. China's first million tons of hydraulic press is the free forging hydraulic press. Four column hydraulic machine is composed of two parts of mainframe and control system. The main body of the hydraulic press includes hydraulic cylinder, beam, column and filling device. The power mechanism is composed of an oil tank, a high pressure pump, a control system, an electric motor, apressure valve, a direction valve, etc.. The hydraulic press is suitable for pressing process of plastic material. Processes such as powder products molding, plastic products forming, cold (hot) extrusion of metal forming, sheet drawing and cross compression, bending, turning, correction and so on. Four column hydraulic press is an independent body and the electrical power system, and centralized control buttons, can realize the adjustment, manual and semi - automatic three kinds of mode of operation.First, the characteristics of the equipmentMachine is an independent body and the electrical power system, the centralized control buttons, can realize the adjustment, manual and semi - automatic three working mode: the machine working pressure, pressing speed, fast no-load downward and deceleration stroke and scope can according to the need of the process adjusted and can complete the ejection process, with the top of the process and drawing process of three kinds of process, each process and constant pressure, Cheng two process action choice, constant pressure molding process after the suppression with ejection delay and automatic return.Independent power organization and electrical system, and the use of button centralized control, can be completed and semi automatic adjustment of two methods of operation. Itsmobile station is driven by a variable frequency controller, which is the world's leading electrical PLC programmable controller. After YH25 - 315D "t" shape move action table depicting the production innovation, is conducive to progress the series hydraulic machine automation, progress produces power, decreased operator labor intensity.Using liquid as the medium to transmit energy, using advanced composite cylinder hydraulic circuit, low oil temperature, air travel speeds were 10MM/ seconds or more, industry and trade into the speed of 20 mm / sec, standby equipment, fast moves up and down sliding noise less than 75 dB, adopts four-column.three-plate structure, activities in the vertical accuracy by four precise guide set of control, anarbitrary point of the work surface and the working surface of parallel precision achieves 0.08mm below.1 reduce the quality and save the material. For automobile engine bracket, radiator bracket and other typical parts, hydraulicThe forming part is reduced by 20%~40% than the pressing part, and the weight of the 40%~50% can be reduced by the hollow stepped shaft parts.2 reduce the number of parts and tooling and reduce die cost. Hydraulic forming parts usually only need 1 sets of mold, but most of the stamping parts. The engine bracket parts of the hydraulic forming are reduced from 6 to 1, and the radiator bracket parts are reduced from 17 to 10.3 can reduce the subsequent mechanical processing and assembly of welding. Take the radiator bracket as an example, the heat dissipation area increased by 43%, solder joint from 174 to 20, the process from 13 to 6, the productivity increased by 66%.4 to improve the strength and stiffness, especially the fatigue strength, such as the hydraulic forming of the radiator support, its stiffness in the vertical direction can be increased by 39%, the horizontal direction can be increased by 50%.5 lower production costs. According to the statistical analysis of the application of the hydraulic forming parts, the production cost of the hydraulic forming parts is lower than that of the stamping parts by 15%~20%, and the die cost is reduced by 20%~30%.Two, structural typeAccording to the direction of the force, the hydraulic machine has two kinds of vertical and horizontal. Most of the hydraulic press is vertical, extrusion with liquid, the structure of the machine is more horizontal. According to the structure type, hydraulic machine with double column, four poster, the eight columns, welding framework and multi-layer steel strip winding frame type, medium and small vertical hydraulic machine also useful C type rack. Type C typehydraulic press three open, easy to operate, but poor rigidity. The welded frame typehydraulic press used for stamping is rigid, and is open and closed. In the upload of vertical column free forging hydraulic machine, an oil cylinder fixed in the beam, the plunger piston and the movable beam rigid connections, movable beam by a guide post, in the working fluid under pressure on mobile. The beam has a front and back working table. The anvil and the lower anvil are respectively mounted on the moving beam and the working table. The working force is composed of the upper and lower beams and columns. Three working cylinders are used in large and medium sized free forging press driven by pump accumulator to get three working force. The working cylinder is also provided with a balancing cylinder and a return cylinder which are applied to the upward force.Three, working principleFour column hydraulic machine hydraulic system is composed of a power mechanism, a control mechanism, execution mechanism, auxiliary mechanism and working medium. The power mechanism usually adopts the oil pump as the power mechanism. In order to meet the requirements of the implementation of the speed of movement of the actuator, the use of an oil pump or a plurality of oil pump. Low pressure (oil pressure less than 2.5MP) gear pump; medium pressure (less than 6.3MP) with the vane pump; high pressure (oil pressure less than 32.0MP) with a plunger pump. Pressure processing all kinds of plastic materials and forming, such as stainless steel plate sheet extrusion, bending, stretching and metal parts of cold pressure forming, and can also be used for the suppression of powder products, grinding wheel, bakelite, thermosetting resin products.中文译文液压机的发展现状及趋势1 前言随着近50年的科学技术的进步与发展，液压技术已经成为了一门影响现代机械装备技术的重要基础学科和基础技术，液压机是一种利用液体压力来传递能量,以实现各种压力加工工艺的机床。

液压支架的发展与前瞻(外文资料与中文翻译)
外文资料与中文翻译外文资料：The hydraulic pressure support development with first gazes[ Key word ] hydraulic pressure support; Control; Intellectualization1 hydraulic pressure supports developmentThe hydraulic pressure support is take the high-pressured liquid as a power, by certain hydraulic pressure part (cylinder, pipe accessory) one kind of strut and the control roof mining coal working surface equipment which becomes with some steel work combinations. Has the intensity high, the travelling speed quick, support the performance good, safe is reliable and so on the characteristic. Since the 20th century 50's, the hydraulic pressure support has gradually become the mining coal working surface core equipment, in the world mainly produced the coal country to invest the massive manpower physical resource and the financial resource carries on the research development to it. At present, support tends to take the hydraulic pressure support as the main body maturely, in the world has produced makes several hundred kind of frames and the up to ten thousand kind of models hydraulic pressure support, meets each kind of coal bed mining support need. On the century 60's, our country once has also developed 10 kind of hydraulic pressure supports, because all sorts of reasons have not obtained the promoted application, the hydraulic pressuresupport is in the development, the experimental stage; The 70's successively from England, Germany, Poland, former Soviet Union and so on mainly produce the coal country to introduce several 10 sets of hydraulic pressure supports. After the unceasing exploration, the use, the digestion and the summary, make each kind of type the support, it is the beginning which the domestically produced hydraulic pressure support develops; The 80's hydraulic pressure support research and development is in the innovation to enhance the stage, develops 30 kind of new frames one after another, makes the ZZ series, the XY series, the ZD series and so on the different specification, and widely uses in the state-owned large and middle scale coal mines, obtains the good economic efficiency; 90's special hydraulic pressure support development obtains the rapid development, the mechanized shop net support, the water granulated substance fills the support, the reason support, the force support, puts goes against the coal support and so on to be published one after another; This century along with the computer technology, the automated technology popularization and the application, the hydraulic pressure support control obtains unprecedentedness to progress, gradually to the procedure control, the numerical control, the remote control and the automated control makes great strides forward.2 domestic and foreign hydraulic pressure supportsdifferenceThe domestically produced support in the manufacture technology, the material quality performance, the processing craft, the control system and inthe sealing property compares with the overseas advanced countries has the very big disparity.2.1 processings manufactures aspectAccording to the related synthesis picks the engineers and technicians to reflect that, the domestically produced hydraulic pressure support craft technology, the service life, the operational performance, use the material quality so far not yet to achieve in 1979 introduced 100 sets of supports the technical levels. If structural material: Germany uses the ST52 material it yield strength is 500 MPa, but our country uses 16 Mn material yield strength is only 350 MPa; Valve class: Overseas always uses the copper alloy valve shell and the high strength stainless steel valve core, our country is the 45# steel adds surface heat processing; In processing craft: The overseas cylinder endophragm is duplicate plates, the domestic product for does not plate, causes the column premature to appear the spot in the use process, scratches and so on the seal leaks the fluid phenomenon, affects support the effect. The domestically produced hydraulic pressure support and the overseas production hydraulic pressure support compares the average to reduce 2 ~ 3 a service life.2.2 control systems aspectThe domestically produced hydraulic pressure support control system research and development is at backwardness condition, seriously restricted the support to move supposes the speed the enhancement and the synthesis picks the economic efficiency the display. In the world several mainly produce the coal great nation throughout to enhance the support control system achievement the synthesis to pick the economic efficiency the important method, the 20th century 60's use manually straight control theoperating system; The 70's use the forerunner control system, along with it England first proposed the development electrohydraulic control system, the eighty's tends to maturely; The 90's ladders company develops the entire working surface electrohydraulic control system, follows closely after that Wister to cut down the advantage Asia - shell Switzerland special company to develop more advanced P - M3, P - the M4 electrohydraulic control system. Presently country and so on US, Germany, England, Australia basically all is the programmable electrohydraulic control, but our country still used the hand control system.2.3 hydraulic pressure parts aspectThe hydraulic pressure part research and development speed lags by far to the hydraulic pressure support need to develop. The hydraulic pressure support reliability mainly relies on the hydraulic pressure part reliability, the hydraulic pressure support in the coal mine production applies whether succeeds, the key lies in the hydraulic pressure part the technical performance whether does meet the requirements. Overseas at present uses the great current capacity safety valve, the fluid much controls the cone-way valve, the cut-off valve, initially supports the strength maintenance valve and the column quickly returns at once the fluid valve. To the hydraulic pressure part structural style, the geometry size, the choice of material, the heat treatment method and the surface treatment and so on various aspects have conducted the thorough research and the development. Develops one batch of sealing property well, the sensitivity high, enters the row of fluid ability to be big, the anti- impact load strong each kind of hydraulic pressure part, adapts the hydraulic pressure support operatingperformance request. But our country kind of hydraulic pressure part research and development lags regarding this, at present still continued to use the century for 80's the product, has not formed the hydraulic pressure part universalization, the seriation, the standardization3 hydraulic pressure supports prospects for developmentforecastIn view of the fact that the science and technology high speed development, new technical, the new craft, the new method, the new material unceasing application and the computer technology unprecedented expansion, the hydraulic pressure support future development will have the extremely attractive prospect.3.1 designs ideas renewal, the hydraulic pressure support develops a revolutionMust consider the environment in the hydraulic pressure support design the attribute. Because the hydraulic pressure support working condition is bad, the person, machine the environment reciprocity question appears importantly. The green design is the choice of material, the product structure, the technique, the outward appearance modelling and the color matches according to the certain rule, adopts artistic the method to perform ingeniously to fuse, fully manifests the man-machine environment system the harmonious unification. The unwieldy hydraulic pressure support image safe, reliable, is been easy to service, lowly to consume energy, the high efficiency, the modelling artistic substitutes. This kind of green design, it not only Filtersthe environment and the resources both must meet the economical development needs, and must meet the human survivaldevelopment needs, is the humanity sustainable developmental strategy in support design manifesting. For example: The hydraulic pressure support uses the multi- goals fuzzy design in the design process, requests to support the strength in a big way, moves a speed quickly, weight light, the timber wood are few and so on, each goal determined a function, namely many designs objective function, then the combination optimizes, determination preferred plan.3.2 will adopt the pure water hydraulic pressure technology, the hydraulic pressure support becomes the green machineryThe pure water hydraulic pressure technology is the hydraulic pressure domain development front. It not only has good anti- burns the nature, the radiation, moreover the price also cheaply, does not have the pollution, since the long-time hydraulic pressure support in Surfaceunder has worked, because the use actuating medium is the emulsion, and has many chemical additives (emulsifier, guards against rust medicinal preparation, antiseptic, partner mixture and so on), the micro environmental pollution is extremely serious to the surface below, therefore, the hydraulic pressure support use pure water hydraulic pressure technology, to reduces the coal mine the production cost, protects the environment is beneficial, and may greatly improve the mine pit the work and the security condition. Unceasingly progresses along with the society, the people had a higher request to the dependent survival environment, hoped has a security, the environmental protection, the highly civilized green environment. The time request summoned the hydraulic pressure transmission (to origin in 1605 discovered the Pascal's law) this ancient brand-new technology resurfaced, and received the world the attention. At present, the western nationconcentrates the strength to study this technology, and makes the unprecedented progress. For example: The lubrication attrition question, reasonably selects rubs the vice- material, has the engineering plastics, the structure ceramics, the high polymer material, guards against rust anticorrosion coating and so on. The structure ceramics have the resistance to wear, the anti- cavitation performance is good, the good chemical stability, characteristic and so on lower friction factor, prepares is favoured. Replaces the partial metals material in the hydraulic pressure part with the structure ceramics, big improvement its performance. In brief, the new material success develops and applies, precisely processes technical the unceasing progress, as well as each kind of new structure hydraulic pressure part making, all will become the hydraulic pressure support to use the pure water hydraulic pressure technology to enter the strict non- pollution domain, will provide the extremely attractive application prospects for development.3.3 high tech applications, the hydraulic pressure support tends to the intellectualizationThe advanced science and technology application is mutually seeps each kind of technology, mutually unifies in the foundation mutually assists, mutually promotes and the enhancement, fully uses each kind of related technical the superiority, enhances strong points and avoid weaknesses, after causes the combination the overall function to be bigger than the composition whole sum of each part of function comprehensive interdisciplinary studies.. The many kinds of technologies unceasingly seep to "the mechanical parent substance - hydraulic pressure support", including technical and so on machine, electricity, fluid, light, magnetism servosystem.Specifically said that, is the strength, the speed which outputs by the hydraulic pressure support are a goal, constituted from has output to the input closed-loop system, was involves sensing the technology, the computer control technology, the signal processing technology, the mechanical drive technology, the hydraulic transmission technology and so on. Because fast operating speed, formidable memory function and keen logical judgement function, thus has realized the man-machine dialogue, causes it operation maintenance conveniently, the entire machine function to be strong. The hydraulic pressure support application function unceasingly expands, unceasingly strengthens to the mine pit coal bed geology condition compatibility, production benefit to equipment dependent degree increasingly big, the operational reliability is more important. The breakdown diagnosis technology (including signal examination, breakdown judgement, failure detection, content and so on fault analysis) along with the high tech development theory (for example wavelet technology, nerve network, artificial intelligence and so on) will enter the hydraulic pressure support the early diagnosis, the prevention and the reduced accident occurrence, service blindness and the maintenance time, will lengthen the support service life, will enhance the production efficiency.4 concluding remarkIn summary, the hydraulic pressure support at present develops the main tendency is: Two columns shields type, enhances the hydraulic pressure support intensity, the design factor, moves a speed, the improvement individual part structure (overall top-beam, width center distance and so on), hydraulic pressure pipe accessory seriation,standardization, universalization, high working resistance, redundant reliability, with micro electron technology realization machine electrohydraulic integration digital gathering, operating mode monitor, breakdown diagnosis and automatic control.Hydraulic pressure support battery solution control engineering researchand applicationKey word:Hydraulic pressure support;Battery solution control system;Design applicationA coal mining technology significant innovation. At present,The battery solution control technology in synthesis and so on US, Germany picked the technical leading country to obtain the widespread application,But our country then only then gradually the necessary use battery solution controls the technology in recent years on some hydraulic pressure supports1 battery solution control technology basic principle and main composition1.1 Battery solution control technology basic principle（1）Bidirectional neighbour control system.The synthesis picks working surface each support has the frame to control the box,The operator controls the box choice neighbour control mode through the support frame,Then sends out the corresponding control command according to the instruction (to produce electrical signal),Causes electro-magnet or micro electrical machinery movement which on neighbour corresponds,Let the electrical signal transform as the hydraulicpressure signal,Controls the host to control the valve to open,Supplies the fluid to the support hydraulic cylinder,Realization neighbour support corresponding movement. The support working mode active status feeds back the frame by the position transmitter and the pressure transmitter to control the box,The frame controls the box to decide the support again according to the sensor feedback signal the next movement.（2）Bidirectional becomes the group control system.Arranges the working surface support is certain groups,In on this group of in first frames presses the frame by the operator to control the box the start key,Sends out an instruction,Neighbour presses the pre-set sequence movement,After moves the frame to complete automatically sends out the control signal to control the box for next,Next starts the movement. Infer from this,In realization group support automatic control.（3）Entire working surface automatic control system.The function consummates battery solution.The control system is equipped with the main control console, the infrared installment,Can realize the support and the coal mining machine linkage entire working surface automation control. Its principle is:On each support frame controls the box with the main control console networking,When the support infrared receiving device receives the position which the coal mining machine infrared launcher sends out to believe.After number,The feedback gives the main control console,The main control console sends out the instruction according to the feedback signal,Causes the corresponding support movement.1.2 Main constituent（1）Battery solution controller (SCU).The battery solution controller is a control system department.Series "heart",It by microprocessor, the intelligence transmission unit, operates the keyboard and the data receiving device and so on is composed. The battery solution controller has two aspects the functions:On the one hand is defers to the operational order and the pre-set sequence completes the solenoid valve group to open shuts,Then control support column, hoisting jack movement;On the other hand it receives the condition data which on the support obtains (including pressure, displacement and so on) and performs to analyze the judgment,Then controls the support the movement,And demonstrates the support state variable and the support breakdown.（2）Battery solution control valve group (FZ).The control valve group is one kind of multipurpose control hydraulic pressure solenoid valve,May replace the fluid cycle selector valve,This kind of valve assembly has causes the support movement the valve group and the surveillance support working condition pressure switch,Opens or the closed valve passage according to the controller instruction.（3）Central control bench (MCU).Whether the system does use MCU,Must the working surface automated horizontal height which determined according to the user decide. Only installs the battery solution controller,Even does not need to install the ground master control room (MCU1) and the mine shaft control room (MCU2),Also may realize the entire automation. The lowest level control system is a bidirectional neighbour unicontrol,What at present is commonly used is "as soon as controls four" the system,Then expands to the automaticarrangement, becomes the group to control, to become the group to pass and the combination function and so on,These all do not need the central control bench.（4）Periphery accessory.The battery solution control system has can surveyCondition, And transforms the hydraulic pressure parameter into the electronic signal original part pressure transmitter,The reflection passes the hoisting jack travelling schedule position contact sensor as well as uses for automatically to start the coal mining machine long-distance control hydraulic pressure support battery solution controller the infrared receiver and so on. All sensors all have respective output signal,Thus may discover the position which the line severs,And is distinguished by each support battery solution controller. If the system matches in the mine shaft working surface or the ground control roomHas the central control bench,Has the breakdown cable line or the sensor can demonstrate on the key station screen,Like this very easy definite breakdown position battery solution control flow like chart 1 shows2 、battery solutions control the support the merit Below this support and the hand control system compare has the merit （1）The support travelling speed is quick.At present the domestic hydraulic pressure support is es the hand control,It passes the speed besides to receive the system current capacity and the hydraulic pressure part has flowed the ability the limit,The worker also has the direct influence in the bay travelling speed to it,This kind of influence appears the outstandingly in the thin coal bed. The batterysolution control support work process may automatically circulate carries on,Sped up moved a speed form eight to ten mintenuse,This speed can follow form13113 to 1315m/Min coal mining machine speed,Shan Taibeng current capacity 400 L/Min,Needs 2 to pump the simultaneous working. Satisfied the high efficiency coal mining machine fast to cut..（2）Improved the roof to support and protect the condition.Because uses to press every timeNiu operates,May enable the support to follow close on after the coal mining machine carries on supports and protects,Moreover,Must act the support requests its two sides the support fastening to support and protect the roof,This characteristic and the correct strut unify,The guarantee forms a firm protecting band along the working surface.（3）Guaranteed the hydraulic pressure support fixed initially supports the strength.Battery solution control system.The passable excess pressure sensor feedback signal or lengthens the control electromagnetism the pilot valve on time realization at the beginning of support to support the strength self-preservation first. Guaranteed fixed initially supports the strength,Reduced the column to increase anti- needs the time,Enhanced has supported and protected the efficiency,Also the entire working surface at the beginning of support supports the strength evenly to be consistent,Improved the roof control（4）May have the pressure to move the frame.Uses the battery solution control system,Is moving the frame.In process,Easy to realize the belt pressure to move the frame,Reduced theworking surface roof to have the frequent impact load to the hydraulic pressure support,Protection roof adjacent formation stability,Lengthens the hydraulic pressure support the service life.（5）Improved the working surface straight line.With manual operationcompared to,The overwhelming majority battery solution control support all is pusher type,This meant the conveyer pulls the phenomenon to be few,Causes all supports by the biggest displacement quantity to abut in a working surface conveyer armored cable side,Maintains a straight working surface. Moves a step of distance to be accurate,Cuts the crest line to be neat,Improved has supported and protected the effect,And causes the scraper conveyer and the entire working surface straight line. The nature is good,The coal mining machine truncation depth is accurate. Improved the scraper conveyer and the coal mining machine operating mode. Moreover at the same time the multi- frames pushes slides,Slowly causes the scraper conveyer to be curving,Avoids the chute attachment point having the oversized stress.（6）Improved the support operator's working condition.Battery solution controltechnical application,Has realized the hydraulic pressure support remote control operation,But indirect maintenance,The worker work condition and the labor intensity have the enormous improvement,Because uses the computer automatic control,Reduced worker's misoperation.（7）The operation flexibility is big.Supports and protects the system the support operation sequence is very easy to change,May act according to the different mining condition,Issuitable specially for the thin coal bed and inclines anxiously the coal bed,Also may use in the drum coal mining machine working surface,Also may use in the coal plow working surface;Also may use in promptly supporting and protecting (moves first frame boosts slides) supports and protects the way,Also after may use in lags supports and protects (pushes first slides moves) supporting and protecting the way.（8）The system can realize the long-distance procedure control.The operator may the root.According to coal mining machine coal cutting choice of direction best position,Has avoided operator's casualty,At the same time also reduced the dust to the body the harm.（9）The battery solution control system may and the coal mining machine and the scraper conveyer.Automatic control system coordination linkage,Realizes the entire automated synthesis to pick the working surface. The support and the coal mining machine running status and the data may transmit to the tunnel in the main control console and the ground central control center,Is advantageous for the realization entire mine pit automated management.3、domestic and foreign development surveysAt present US, Germany and so on walk in this technology in the world front row,Its hydraulic pressure support battery solution control technology disposition has the breakdown to diagnose the early-warning installation,May realize the hydraulic pressure support and the coal mining machine, the scraper machine linkage and the long-distance control. Our country develops the hydraulic pressure support battery solution control system start to be late,Has developed successfully the first entire workingsurface hydraulic pressure support battery solution control system since 1995,Also has the many kinds of models the battery solution control system hydraulic pressure support to be published. But our country produces battery solution control system hydraulic pressure support also not in mine shaft promotion use,Many high production highly effective working surfaces use the battery solution control system hydraulic pressure support also to have from the overseas import. The support battery solution control system develops which from our country looked,Still was in Shan Jia and becomes the group procedure to control.System initial stage. In the system does not have the main control console,Support and coal mining machine linkage entire working surface automatic control system also in development stage. Zhengzhou coal mine mechanical group limited liability company in the last few years through and German DBT Corporation, emperor fragrance Bach company and so on cooperation,The overseas advanced battery solution valve the hydraulic pressure support which will produce with this company necessary,Takes the lead to put into the use in the Jincheng coal industry group,Has met the design requirements completely,Has coal industry group 6 syntheses successively and so on the Jincheng, god China picks working surface nearly 800.The battery solution control hydraulic pressure support already or was going to put into the use. ZY4400 /9 /21 thin coal bed coal plow working surface battery solution control hydraulic pressure support and the ZY8640 /2,515 /55 manufacture domestically picks the high shield type hydraulic pressure support through to have the product appraisal in pairs greatly which four Chinese Academy of Science academicians participates(appraisal),The appraisal thought these 2 kind of supports overall performance achieves the world advanced level. Moreover,Corporate design manufacture Chinese god China localization battery solution control hydraulic pressure.Support ZY7600 /22 /45/The world is highest 612 meter two columns shields type battery solution control hydraulic pressure support ZY9400 /28 /62 has all represented the domestically produced support maximum level,Achieved or approaches the world advanced level.Above two articles originate from Elsevier the ScienceDirect periodica液压支架的发展与前瞻[关键词] 液压支架; 控制; 智能化1液压支架发展概述液压支架是以高压液体为动力,由若干个液压元件(油缸、阀件)与一些金属构件组合而成的一种支撑和控制顶板的采煤工作面设备。

机械工程及自动化专业外文翻译--液压支架的应用及意义(中文)
中文译文：液压支架的应用及意义随着工业技术的不断发展，国民经济对煤炭需要量的日益增加，煤矿开采，特别是采煤工作免得生产技术面貌发生了巨大的变化。
自1954年英国装备了世界上第一个液压支架工作满开始，采煤技术实现了综合机械化。
综合机械化采煤，就是工作面采煤，运输和支护三大主要生产环节都实现机械化。
也就是说，采用滚筒式或刨削式等采煤机械落煤与装煤；工作面重型可弯曲运输机，以及与之适应的顺槽转载机和可伸缩皮带运输机等运煤；自移式液压支架支护和管理顶板。
这几种设备相互配合，组成了综合机械化采煤设备。
液压支架是以高压液体为动力，由若干液压元件（油缸和滑件）与一些金属结构件组合而成的一种支撑和控制顶板的采煤工作面设备，能实现支撑，降落移架和推移运输机等一整套工序。
液压支架技术上先进，经济上合理，安全上可靠，当前世界各国都在不断地提高采煤工作面的综合机械化水平。
我国于1964年开始研制液压支架，已先后试制了MZ-1928型,TZ型,BZZC型,WKM-400型,DM-400型,YZ型,ZYZ型,ZY型等多种形式的液压支架，并在开滦，大同，阳泉，鹤壁，徐州，铜川，义马，淮北等局矿进行了试验和使用，取得了较好的效果。
1974年以来，从西德，英国，前苏联和波兰等国引进了许多不同类型的液压支架。
实践证明，液压支架具有强度高，支护性能好，移设速度快，安全可靠等优点，能使采煤工作面达到高产量，高回采率和高工效，能大大减轻劳动强度，降低成本和掘进率，实现安全生产。
国外放顶煤液压支架放顶煤综采能否成功还取决于能否针对具体的使用条件进行放顶煤液压支架的合理选型和设计。
一般说来，它要满足对顶煤具有良好的支护效果，同时还要满足顺利放煤，运煤，行人，通风，移架和对采煤工作干扰小等一系列要求。
国外的放顶煤液压支架发展较早。
法国60年代初就成批生产放顶煤液压支架。
现将各主要放顶煤液压支架生产国家研制，生产，使用的放顶煤支架及其主要特点做一简要介绍。

英文文献Hydraulic support's development and perspective1 domestic and foreign hydraulic support development outlineThe hydraulic support is take the high-pressured liquid as a power, by certain hydraulic element (cylinder, pipe accessory) one kind of support and the control roof mining coal working surface equipment which becomes with some steel work combination. Has the intensity to be high, the traveling speed is quick, supports and protections performance good, safe reliable and so on characteristics. Since the 20th century 50's, the hydraulic support has become the mining coal working surface core equipment gradually, in the world mainly produced the coal country to put in the massive manpower and resources and the financial resource carries on the research development to it. At present, tends to be mature take the hydraulic support as the main body supports and protections, in the world already the manufacturing several hundred kind of frames and the up to ten thousand kind of model's hydraulic support, meets each kind of coal bed mining supports and protections need.On the century 60's, our country once had also developed 10 kind of hydraulic supports, for various reasons has not obtained the promoted application, the hydraulic support is in the development, the laboratory stage; the 70's from Britain, Germany, Poland, the former Soviet Union and so on mainly produce the coal country to introduce several 10 set of hydraulic supports successively. After the unceasing exploration, the use, the digestion and the summary, make each type the support, it is the beginning which the domestic product hydraulic support develops; the 80's hydraulic support research and development are in the innovation to enhance the stage, develops 30 kind of new frame one after another, makes the ZZ series, the XY series, the ZD series and so on differentspecification, and widely uses in the state-owned large and middle scale coal mines, obtains the good economic efficiency; 90's special hydraulic support's development obtains the rapidly expand, the mechanized shop net support, the water granulated substance backfill support, the reason support, the force support, puts goes against the coal support and so on to be published one after another; The present century along with the computer technology, the automated technology's popularization and the application, hydraulic support's control makes the breakthrough progress, gradually to the programmed control, the numerical control, the remote control and the automated control makes great strides forward.2 Domestic and foreign hydraulic support differenceThe domestically produced support in the technique of manufacture, the material quality performance, the processing craft, the control system and in the sealing property compares with the overseas advanced countries has the very big disparity.2.1 Processing manufacture aspectAccording to the related synthesis picks the engineers and technicians to reflect that the domestic product hydraulic support's processing technology, the service life, the operational performance, used the material quality so far not yet to achieve in 1979 to introduce 100 set of support's technical levels. If structural material: Germany uses the ST52 material its yield strength is 500 MPa, but our country uses 16 Mn material yield strength is only 350 MPa; Valve class: Overseas has used the copper alloy valve shell and the high strength stainless steel valve core, our country has been the 45# steel adds the superficial heat treatment; In processing craft: The overseas cylinder endophragm is duplicate plates, the domestic product for does not plate, causes the column premature to present the spot in the use process, scratches and so on seals to leak the fluid phenomenon, affects the supports andprotections effect. The domestic product hydraulic support and the overseas production's hydraulic support compares the average to reduce 2~3 service lives.2.2 Control system aspectThe domestic product hydraulic support control system's research and development are at backwardness condition, restricted the support to move seriously supposes the speed the enhancement and the synthesis picks the economic efficiency the display. In the world several mainly produce the coal great nation to enhance the support control system achievement the synthesis to pick throughout the economic efficiency the important means that the 20th century 60's use manual controls the operating system straight; the 70's use the forerunner control system, along with it Britain first proposed that the development battery solution control system, the 80's tends to be mature; the 90's ladder company develops the entire working surface battery solution control system, follows Wister to cut down Liya - the Beiruite company to develop more advanced P - M3, P - the M4 battery solution control system. Present countries and so on US, Germany, Britain, Australia basically all are the programmable battery solution controls, but our country still used the hand control system.2.3 Hydraulic element aspectHydraulic element's research and development speed lags by far in the hydraulic support need to develop. Hydraulic support's reliability mainly relies on hydraulic element's reliability, the hydraulic support in the coal mine production applies whether to succeed, the key lies in hydraulic element's technical performance whether to meet the requirements. Overseas uses the great current capacity safety valve, the fluid to control the cone-way valve, the cut-off valve at present, initially to support the strength maintaining valve and the column returns to the fluidvalve fast. To hydraulic element's structural style, the geometry size, the choice of material, the heat treatment method and the surface treatment and so on various aspects have conducted the thorough research and the development. Develops one batch of sealing property to be good, the sensitivity high, enters the row of fluid ability in a big way, the anti-impact load strong each kind of hydraulic element, adapts the hydraulic support operating performance request. But our country lags to this kind of hydraulic element research and development, at present still continued to use on the century 80's products, has not formed the hydraulic element universalization, the seriation, the standardization.3 Hydraulic support prospects for development forecastIn view of the fact that science's and technology's high speed development, new technology, new craft, new method, the new material will apply and the computer technology unprecedented expansion unceasingly, hydraulic support's future development has the very attractive prospect 3.1 The design idea's renewal, the hydraulic support develops a revolutionMust consider the environment in the hydraulic support design the attribute. Because hydraulic support's working condition is bad, the human, machine the environment reciprocity question appears more important. The green design is the choice of material, the product mix, the technique, the outward appearance modelling and color matching according to certain rule, adopts artistic the method to perform the ingenious fusion, manifests the man-machine environment system's harmonious unification fully. The unwieldy hydraulic support image safe, reliable, easy to be serviced, consumes energy, the high efficiency, the handsome appearance to substitute lowly. This kind of green design, it is not only feared the environment and the resources both must meet the economic development needs, and must meet the human survival developmentneeds, is the humanity sustainable development in support design manifestation. For example: The hydraulic support uses themulti-objective fuzzy design in the design process, requests to support the strength to be big, moves to a speed to be quick, the weight is light, timber wood few and so on, each goal determined that a function, namely many project objective function, then the combination optimizes, determination preferred plan.3.2 Will adopt the pure water hydraulic technique, the hydraulic support will become the green machineryThe pure water hydraulic technique is the hydraulic pressure domain development front. It not only has good anti-burns the nature, the radiation, moreover the price to be also cheap, does not have the pollution, for long the hydraulic support works under the surface layer, because the use actuating medium is the emulsion, and has many chemical additives (emulsifier, rust-preventing agent, antiseptic, coupling agent and so on), the micro environmental pollution is very serious to the surface below, therefore, the hydraulic support use pure water hydraulic technique, to reduces the coal mine the production cost, protects the environment is beneficial, and may improve the mine pit greatly the work and the safety condition. Progresses unceasingly along with the society, the people had a higher request to the dependant survival's environment, hoped that has a security, the environmental protection, the highly civilized green environment. The time request summoned the hydraulic pressure transmission (to origin in 1605 discovered that the Pascal's law) this ancient brand-new technology resurfaced, and received the world the attention. At present, the Western country the concentrate efforts to study this technology, and makes the breakthrough progress. For example: The lubrication attrition question, selects reasonably rubs thevice-material, has the engineering plastics, the structure ceramics, thehigh polymer material, rust prevention anticorrosion coating and so on. The structure ceramics have the resistance to wear, the anti-cavitation performance is good, the good chemical stability, characteristics and so on low friction factor, enjoy the favor. Replaces the partial metallic material in the hydraulic element with the structure ceramics, big improvement its performance. In brief, the new material's success develops and applies, the precision sizing technology's unceasing progress, as well as each kind of new structure hydraulic element's make, will become the hydraulic support to use the pure water hydraulic technique to enter the strict non-pollution domain, provides the very attractive application prospects for development.3.3 High tech's application, the hydraulic support tends the intellectualizationThe advanced science and technology application is seeps mutually each kind of technology, unifies mutually in the foundation is mutually auxiliary, promotes mutually and enhances, uses each kind of correlation technique fully the superiority, enhances strong points and avoids weaknesses, after causing the combination the integrated function is bigger than the composition whole sum of each part of function comprehensive interdisciplinary studies. Many kinds of technologies seep unceasingly to “the mechanical parent substance - hydraulic support”, including technical and so on machine, electricity, fluid, light, magnetism servers. Specifically speaking is the strength, the speed which outputs by the hydraulic support is the goal, constituted from the output to the input closed-loop system, is involves the sensing technology, the computer control technology, the signal place technology, the mechanical drive technology, the hydraulic transmission technology and so on. Because fast operating speed, formidable memory function and keen logical judgment function, thus has realized the man-machine conversation, causesit operation maintenance to be convenient, complete machine function. The hydraulic support application function expands unceasingly, strengthens unceasingly to the mine pit coal bed geological condition compatibility, the production benefit is getting bigger and bigger to equipment's dependant degree, the operational reliability is more important. The failure diagnosis technology (including signal detection, breakdown judgment, failure detection, contents and so on fault analysis) along with high tech's development theory (for example wavelet technology, neural network, artificial intelligence and so on) will enter hydraulic support's early diagnosis, the prevention and the reduced accident's occurrence, service blindness and the maintenance time, lengthens the support service life, raises the production efficiency.中文翻译液压支架的发展与前瞻1国内外液压支架发展概述液压支架是以高压液体为动力,由若干个液压元件(油缸、阀件)与一些金属构件组合而成的一种支撑和控制顶板的采煤工作面设备。
