这款半封闭压缩机配有三相二极异步电动机(在50Hz时,转速为2900转/分)直接驱动阳转子,再带动阴转子转动。

压缩机配有高效油分离器,使得在安装制冷系统时无需配置任何外加部件。

电动机是通过特定的孔、槽由吸气来冷却。

对于SRC-S系列型号压缩机,制冷量调节是通过油压作用在油缸活塞带动滑阀来实现的。

活塞的位置决定了吸气腔容积的大小。

与此相反,对于134-XS系列型号,活塞的移动是由制冷剂气体旁通回压缩机吸气侧来实现的。

此两种系列的压缩机适用于制冷剂R22、R407C、R134a、R404A和R507的制冷系统。

紧凑型设计、低噪音、高效率、多机型和简便安装,使得此款压缩机能够满足主机制造厂商生产高效率和性能优良的水冷、风冷和热泵等机组。

它以汽轮机(蒸汽透平)为动力,蒸汽在汽轮机内膨胀做功驱动压缩机主轴,主轴带动叶轮高速旋转。

被压缩气体从轴向进入压缩机叶轮在高速转动的叶轮作用下随叶轮高速旋转并沿半径方向甩出叶轮,叶轮在汽轮机的带动下高速旋转把所得到的机械能传递给被压缩气体。

因此,气体在叶轮内的流动过程中,一方面受离心力作用增加了气体本身的压力,另一方面得到了委很大的动能。

气体离开叶轮进入流通面积逐渐扩大的扩压器,气体流速急剧下降,动能转化为压力能(势能),使气体的压力进一步提高,使气体气体压缩。

本仿真培训系统选用甲烷单级透平压缩的典型流程作为仿真对象。

在生产过程中产生的压力为1.2~1.6kg/cm2(绝),温度为30℃左右的低压甲烷经VD01阀进入甲烷贮罐FA311,罐内压力控制在300mmH2O。

甲烷从贮罐FA311出来,进入压缩机GB301,经过压缩机压缩,出口排出压力为4.03kg/cm2(绝),温度为160℃的中压甲烷,然后经过手动控制阀VD06进入燃料系统。

该流程为了防止压缩机发生喘振,设计了由压缩机出口至贮罐FA311的返回管路,即由压缩机出口经过换热器EA305和PV304B阀到贮罐的管线。

返回的甲烷经冷却器EA305冷却。

另外贮罐FA311有一超压保护控制器PIC303,当FA311中压力超高时,低压甲烷可以经PIC303控制放火炬,使罐中压力降低。

活塞式压缩机手册

活塞式压缩机手册

制冷压缩机概述一、制冷压缩机的作用制冷压缩机是制冷装置中最主要的设备,通常称为制冷装置中的主机。

制冷剂蒸气从低压提高为高压以及汽体的不断流动、输送,都是借助于压缩机的工作来完成的,也就是说,制冷压缩机的作用是:1、从蒸发器中吸取制冷剂蒸气,以保证蒸发器内一定的蒸发压力。

2、提高压力,将低压低温的制冷剂蒸气压缩成为高压高温的过热蒸气,以创造在较高温度(如夏季35℃左右的气温)下冷凝的条件。

3、输送并推动制冷剂在系统内流动,完成制冷循环。

二、制冷压缩机的种类及工作原理制冷压缩机的种类和形式很多,根据其基本工作原理,可分为容积型和速度型两大类。

1、容积型容积型压缩机是*工作腔容积的改变实现吸气、压缩、排气等过程。

容积型压缩机根据其工作部件的运动形式,又可分为往复式和回转式,前者活塞在气缸内作往复运动,而后者是工作部件在气缸内作回转运动,如图5-1所示的螺杆式、滑片式等压缩机均为回转式。

但目前制冷工业上使用最广泛的为活塞式压缩机,且机型有几十种之多。

2、速度型速度型压缩机是*高速旋转的工作叶轮对蒸气作功,使压力升高并完成输送蒸气的任务。

这类压缩机根据蒸气的流动方向分为离心式和轴流式两种,其中应活塞式压缩机一、活塞式压缩机的分类1、按所采用的工质分类,一般有氨压缩机和氟利昂压缩机两种。

按压缩级数分类,有单级压缩和两级压缩。

单级压缩机是指压缩过程中制冷剂蒸气由低压至高压只经过一次压缩。

而所谓的两级压缩机,压缩过程中制冷剂蒸气由低压至高压要连续经过两次压缩。

2、按作用方式分类,有单作用压缩机和双作用压缩机。

其制冷剂蒸气仅在活塞的一侧进行压缩,活塞往返一个行程,吸气排气各一次。

而双作用压缩机制冷剂蒸气轮流在活塞两侧的气缸内进行压缩,活塞往返一个行程,吸、排气各两次。

所以同样大小的气缸,双作用压缩机的吸气量较单作用的大。

但是由于双作用压缩机的结构较复杂,因而目前大都是采用单作用压缩机。

3、按制冷剂蒸气在气缸中的运动分类,有直流式和逆流式。

Compressornon-safe operations, even if these precautions or non-safe operation is not mentioned in this manual.Chapter II Installation Standards and Requirements1. Requirements for Arrangement in Installation Place(1) Compressor house should be as near to load center as possible, in order to reduce pipe length,pressure loss and power consumption and ensure air supply pressure.(2) Scientific supply of electrical power, water supply and ventilation should be taken intoaccount in the house planning.(3) To suit to the development in the future, space should be reserved on the general drawing forexpansion.(4) Air compressor suctions air directly from atmosphere. In order to reduce the possible wear,corrosion and explosion of compressor unit, there must be specified distance between the compressor house and the place where there is explosive, corrosive, toxic gas or dust or other harmful substances, and the compressor house should be located on lower side of annual wind directions occurring at least frequency in aforesaid places, so that the effect of harmful substances on the house is minimized.(5) Since the compressor gives out a plenty of heat, especially in summer when high temperatureexists inside the unit, the compressor house should be oriented to the direction in which the machine is well-ventilated and the sunshine time can be reduced.(6) Though the compressor is provided with casing, raining on it is strictly prohibited. Hencecompressor should be not mounted outdoors.(7) Compressor house should be a separate building.2. Precautions during Handling(1) In order to ensure safe handling, please pay attention to the total weight of the compressorunit.(2) When the unit is handled on a fork, soft gaskets should be used for protecting the unit fromsurface damage. The fork teeth should be inserted completely into the compressor base.(3) When the unit is handled with the help of a crane, balancing should be ensured. The steel wirerope should be fixed on correct positions and slings should be prepared to prevent the rope from pressurizing on the compressor casing, or otherwise the casing will get damaged.(4) Transportation bracket should be installed and the fixtures should be tightened and locked firstwhen the compressor unit is transported and handled, in order to prevent possible damages to the compressor, as shown in the figure. After compressor unit is mounted in position, it is necessary to remove the bracket and fixtures shown in the figure before the compressor is put into operation!3. Requirements for Compressor House Installation(1) Sufficient space should be reserved in the installation place for subsequent maintenance andrepair work to be done. The floor had better be finished cement floor and its unevenness should not be greater than 0.5/1000 (mm), and the floor should be enough hard and firm to support the weight of the compressor.(2) The compressor should be placed on horizontal floor, and good joint must be ensuredbetween the casing bottom and floor surface, in order to prevent vibrations and noises.(3) If possible, sound absorbing board can be fitted on the walls of compressor house in order tofurther reduce the noises. However, the materials with hard surface (such as ceramic tiles) should not be fitted on the walls.(4) The recommended minimum spacing from compressor installation position to the front side,rear side, left side, right side and the top should be greater than 1m.(5) Since air-cooled compressor is apparently affected by the ambient temperature, thecompressor house should be well-ventilated and dry. An exhaust fan should be mounted in it and sufficient incoming air volume should be provided, in order to ensure that air flowrate is lower than 4.5m/s at air inlet window and ambient temperature should be within –5o C~40o C. The following figure shows compressor ventilation designs:(6) There is a small quantity of dust and clean air as well as no harmful gases, sulfurous acids andother corrosive medium in the compressor house.4. Pipeline Installation Requirements(1)The air outlet of the compressor unit is provided with threaded connector for connection withyour air supply pipeline. Please refer to Chapter III “Performance Parameters and Apparent Dimension of the Unit” for installation dimensions.(2) The branches must be connected from the top of main pipeline in order to avoid condensationwater in the pipes from flowing down into the compressor.(3) The pipeline should be as short and straight as possible when it is laid around the wholeproduction building, in order to minimize the number of bends and valves and the pressure loss. The post treatment system should be provided with maintenance by-pass if possible.5. Connection and Arrangement of Air Pipeline(1) Compressed air pipes are connected by welding, but the pipe and equipment or valve shouldbe connected using corresponding flange or screwed connections. The pipes that are often removed should be connected using screwed connections if the pipe diameter is less than or equal to D N 25, and connected using flanges if the pipe diameter is greater than D N 25.(2) For the pipeline that delivers compressed air that is not dried and purified, the pipelinegenerally should be laid at a slope of more than 2/1000, and a blow-off valve (screwed plug) should be mounted on its low end. The pipeline should be laid as short and straight as possible and least bends and valves should be used, in order to drain the wastewater in the pipes better. (3) The top of underground pipeline should be embedded in 0.7m at least under the ground, butthis restriction is not applicable to the pipeline that delivers dry and purified compressed air. (4) After completion of system installation, air pressure test and air-tightness test should becarried out, and hydrostatic test should not be carried out. The test pressure is 1.05~1.5 times the pressure of the same gas, and if no leakage is detected, the pipeline is acceptable.(5) Air receiver tank is pressure vessel, and all the necessary safety valve, pressure gauge,blow-off valve and other safety accessories should be mounted correctly and be reported to local labor authority for records. Annual routine inspection must be carried out every year.6. Selection of Pipe SizeWhile gas flows inside the pipeline, it has friction resistance in straight pipes and local resistance in the valves, tees, bends and reduced pipes, which will cause gas pressure loss. Generally, pressure drop in a pipe length can be obtained from the data in following table:Air Flow --- Pipe Pressure Drop kg/cm2 ---(100m)Air flowPipe Diameter (inch)m3/min 1 1/2 2 2 1/2 3 3 1/2 4 56.5 2.50 0.709 0.187 0.0744 0.03467.0 2.90 0.815 0.217 0.0863 0.04017.5 3.33 0.940 0.249 0.0990 0.04608.0 3.79 1.0 0.283 0.113 0.0524 0.02478.5 4.28 1.21 0.319 0.127 0.0590 0.03099.0 4.80 1.35 0.359 0.143 0.0662 0.03479.5 5.35 1.51 0.399 0.159 0.0738 0.038610 5.93 1.67 0.442 0.176 0.0818 0.042812 8.53 2.40 0.637 0.254 0.118 0.0616 0.019614 11.6 3.27 0.866 0.345 0.160 0.0839 0.0260Pipe Diameter (inch) Air flowm 3/min2 2 1/23 3 1/2456 153.76 0.995 0.396 0.184 0.0963 0.0306 164.28 1.13 0.450 0.209 0.110 0.0348 185.41 1.14 0.570 0.265 0.139 0.0441 0.0177 206.68 1.77 0.704 0.327 0.171 0.0544 0.0219 228.08 2.14 0.851 0.396 0.209 0.0659 0.0265 249.62 2.55 1.01 0.471 0.246 0.0784 0.0315 2811.3 2.99 1.19 0.553 0.289 0.0920 0.0370 3015.0 3.98 1.58 0.736 0.385 0.122 0.0429 3520.4 5.41 2.16 1.00 0.525 0.167 0.0670 40 7.08 2.82 1.31 0.618 0.218 0.0876 Notes:1. Actual pressure drop in a straight pipe section = gauge value pipe length (100compression ratio). (Compression ratio = gauge pressure +1);2. The total pressure drop in the pipeline should include the local pressure losses caused in the bends, reduced pipes, tees and valves, which can be found in related manuals.3. After referred to the tables, it is necessary to check whether the pressure loss of compressed air supplied to the user end is within the permissible range. The experienceshows that total pressure loss should not exceed 0.4kg/cm 2 in 100m pipeline length. If itexceeds this value, the pipe diameter must be increased.Chapter III Performance Parameters and Apparent Dimension of the UnitS Type compressor unit is motor-driven immovable oil-spray screw compressor and SF Type unit is air-cooled compressor.

System Flow Process“S” series compressor system has flow process shown in following diagram. It consists of air system, lubricant system and cooling system. Its drive section is classified into belt drive and coupling drive. All the compressors of this series have gear drives.1. Gas pipeline2. Oil and air mixing pipeline3. Oil pipeline4.

Filtering element17. Air-oil separator18. Filling hole19. Blow-off valve20. Temperature control valve21. Engine oil filter22. Oil cooler23. After cooler24. Air supply opening(1) Flow process of air systemAfter dust in the air is removed in the air filter, the air flows through the intake control valve and into the compressor where it is compressed. The compressed oil-air mixing gas enters the air-oil separator. After the air is separated from oil in the separator, the air flows through the min. pressure valve and after cooler, and finally is discharged from air supply valve. The separated oil is left in the tank of the air-oil separator and enters lubricant circulation system.1.1 Air filterThe air filter is dry paper-medium filter. Its function is to purify the suctioned air, guarantee the cleanness inside the system and increase the service life of bearing of the compressor, air-oil separator, filtering element and oil filter. Maintenance frequency should be increased under severe conditions. As shown in the diagram.Air Filter Air Filter Element1.2 Intake control valveThe intake control valve functions together with solenoid valveand pressure switch and is used to control supplied air volumeof compressor. When the compressor unit is started up, thisvalve closes and compressor is started up at low loads. Whenthe compressor runs at full load, this valve is full open. Whenload is adjusted, this valve closes, and reduces the pressure inair-oil separator to 0.3~0.45 MPa, so that the system runs at noload and oil supply pressure can be guaranteed in compressor.It has non-return function, and can prevent reverse flow of theair in air-oil separator, which will cause inverse rotation of therotor and oil spraying from the air inlet, as shown in the diagram:1.3 Temperature switchThe temperature switch also has the function of indicating and controlling the air discharge temperature. Oil loss, insufficient oil volume and bad cooling effect of the system will possibly result in too high discharge temperature. When this temperature reaches the stop temperature setting of the temperature switch, the compressor will stop operation. The stop temperature setting of the temperature switch is 105o C.1.4 Safety valveWhen the load adjustment system malfunctions, and the pressure in air-oil separator is more than 1.1 times the rated discharge pressure, the safety valve will automatically trip and releases the pressure, in order to guarantee safety. When the air pressure is reduced to a certain valve, the safety valve will automatically close.n The safety valve has been adjusted and set correctly before leaving the factory. Please do not make any adjustment!1.5 Min. pressure valveMin. pressure valve is located above the air-oil separator, andits opening pressure is 0.35~0.4MPa. Its main function is asfollows:a. Rapidly establish the air pressure when the compressor isjust started up, provide the pressure needed for lubricationfor compressor, and enable the intake control valve to openin specified time.b. Control the air flow rate in filtering element of the air-oilseparator, ensure the air-oil separation effect and prevent the damages caused to the filtering element due to too great pressure difference.c. It has non-return function and can prevent the pressure gas after min. pressure valve fromflowing back into the air-oil separator when the load is adjustedand the compressor stops.1.6 Pressure ControlThe pressure sensor installed on the after cooler transmits obtainedsignal to a microcomputer-based controller for the adjustment ofcompressor load. When gas supply pressure reaches the upper limitof preset pressure, the microcomputer-based controller sends asignal, which causes gas inlet control valve to be closed andcompressor to run at no load. When gas supply pressure is reducedto the lower limit of preset pressure, the microcomputer-based controller sends a signal to a solenoid valve, which causes all the gas inlet control valves to be opened and compressor to run at full load.SP2 shown in the figure is a pressure switch and can convert the pressure signal into electric signal. This switch is used for overpressure protection control of the compressor. When load adjusting system malfunctions and discharge pressure of the compressor reaches the setting of SP2 pressure switch, SP2 operates and stops the compressor, and then sends overpressure alarm signal.1.7 After coolerThe after cooler is an efficient plate-wing structure and is integrated with the oil cooler. It is used for cooling the high-temperature compressed gas discharged from the compressor in order to control the temperature of supplied air to +15o C or less.2. Flow Process of Lubricating SystemThe lubricant system consists of air-oil separator, temperature control valve, oil cooler and oil filter (refer to the System Flow Chart).The lubricating oil in the air-oil separator enters the oil pipeline under the action of gas pressure, flows through temperature control valve and oil cooler, then is filtered in the oil filter. After than, the oil flow is divided into two branches. One branch is that oil is sprayed into the rotor of compressor from lower part, and the other branch is that oil is led to the front and rear bearing pedestals for bearing lubrication. Then the oil merges in the rotor of compressor, and is mixed with the gas and then is discharged into air-oil separator. After the oil is separated from the air in the separator, the oil stays in the separator and enters next cycle.2.1 Oil coolerOil cooler is an efficient plate-wing structure and is integrated with theafter cooler. It is used for cooling of lubricating oil in order to ensurenormal operation of the system.2.2 Oil filterOil filter is a screwed filter with paper media and its filter precision is10µm. It can remove foreign matters in the oil, for example metal particles,deteriorated oil, etc. in order to guarantee the normal operation of thecompressor. In the oil filter, there is a safety valve. When the filter elementis blocked, or its service life period expires, or the pressure differencebetween front side and rear side of the filter element reaches 0.15~0.2MPa,the safety valve will open, oil is bypassed and is injected into thecompressor without being filtered, which thus avoids the danger of oil lossin the compressor. However, after bypassing, a large quantity of dirtsubstances will be brought into the compressor, and if they are not treatedin time, they will accelerate the bearing wearing and substantially reduceservice life of the machine. Therefore the oil filter must be maintained andreplaced in time!!2.3 Air-oil separatorThe air-oil separator has one filter element in it, and the mainfunction of this filtering element is to separate the mixture of oiland air discharged from the compressor. After this mixture enters the separator, firstly rough separation is carried out in order to remove most of the oil from the air. Then fine separation is carried out, in order to reduce oil content of the air to 1~3PPM or less. Besides, the air-oil separator can store lubricating oil and some pressure air. Caution: the filtering element in the air-oil separator is consumable goods and should be replaced in time!2.4 Temperature control valveThe function of temperature control valve is toautomatically adjust the temperature of lubricating oil.When the temperature of lubricating oil is below 55o C, allthe bypass ports of this valve open and oil does not passthrough the cooler for cooling and is directly injected intocompressor. When the temperature of lubricating oil rises,the bypass ports of this valve close gradually, and when thetemperature of lubricating oil reaches 75o C, all the bypassports of this valve close and all the oil go through the oilcooler and is injected into compressor after cooling. Therefore, on one hand, the valve keeps the air discharge temperature above the pressurized dew point in order to prevent liberation of water in the air and entering the lubricating oil. On the other hand, this valve ensures to rapidly supply lubricating oil to the compressor for lubricating it when it is started up at a low temperature.3. Flow Diagram of Cooling SystemThis series screw compressor is air-cooled compressorand is cooled using fans. The cooling system mainlyconsists of cooling fan, oil cooler and after cooler. Thecooling air is suctioned by the fan, and blows towards theoil cooler and after cooler, and meanwhile it coolscompressed air and lubricating oil.Pay attention to maintenance of coolers!Chapter V. Electrical Control System1. Function of Control SystemRefer to “User’s Manual for Liquid Crystal Display Control System of Screw Compressor”. When the compressor must be stopped under normal conditions, please press “OFF” key on the instrument panel. Then the unit will run for some time at no load, and the motor does not stop until the pressure in the oil-gas separator is decreased to the specified value.The compressor unit will automatically stop if the compressor has abnormal conditions (for example overpressure, overtemperature, etc). There is a mushroom emergent stop button on the operation panel. This button should not be pressed unless there happen abnormal conditions on the unit. Or otherwise, oil will be possibly injected out of the gas inlet of the compressor. When the unit is restarted after the button is pressed and the cause is found and eliminated, this button should be pulled out in order to unchain the unit. Then press “ON” key and 10 sec later press “OFF” key. Repeat the key pressing operations twice in order to ensure that all residual oil flows back to the compressor, so that the unit can operate in good state.2. Requirements for Power Supply and External Connection(1) Main power supply of this compressor is AC three-phase 380V/50Hz. Please confirm that thepower supply is correct.(2) V oltage drop cannot exceed 5% of rated voltage, voltage difference between different phasesshould be within 3% and phase sequence protection wire should be fitted.(3) The power supply of compressor must be provided with disconnecting switch to preventoperation in case of phase loss caused due to shortcircuiting.(4) Check the fuser of secondary circuit, and select proper safety switch without fuser accordingto the power of the compressor.(5) The following table gives the requirements for user’s power supply and recommended lead-insize for the screw compressor made by our company:Compressor Type V oltage(V)Frequency(Hz)Max.

Check Prior to Initial Start-up(1) Check the quantity of lubricating oil in the air-oil separator and the oil quantity is optimalwhen the oil level indicated on oil dipstick is between upper limit and lower limit.(2) The electrical connections and earth connection have been completed, and comply with safetystandards.(3) Air supply pipeline is unblocked, and all the screwed plugs and connections are tightenedfirmly.(4) Check if power supply and voltage of the motor and indications on the instrument panel arecorrect and ensure the compressor will start up at no load.(5) If the compressor commissioning is carried out after a long time since it is delivered, fill about0.5-liter lubricating oil into the air inlet and manually rotate the compressor by severalrevolutions or inch it several times, in order to prevent compressor burning due to insufficient oil at startup. Please take special care not to let foreign matters fall into the machine, which will cause damage to the compressor.(6) Operate the valve according to process pipeline operation requirements and the air dischargevalve of the compressor should be in open position.(7) When it is ready for startup, check whether the operators are in safety position.(8) Close the manual blow-off valve2. Initial Startup(1) First switch on the power supply, and observe that phase sequence indication on theinstrument panel is normal. Then press “ON” key to inch the compressor. For the sake of safety, please check if the unit rotates in right direction as shown by the arrow. If it rotates in right direction, a person can clearly feel that there is suction force at air inlet of air filter (please use one finger to try it). Or otherwise the unit rotates in wrong direction. Immediately switch off the power supply, and change any two of the three power lines. Reverse rotation of the motor is strictly prohibited.(2) Press “ON” key to start the operation, and the compressor will run in the preset mode. At thistime, check if the instruments and indicators are normal and pressure and temperature is normal, and check if are given out and there is abnormal sound and oil leakage. If there is, immediately stop the compressor and check it.(3) Stop the compressor and press “OFF” key, and after delay time and unloading, the unit willcompletely stop. Not immediately stopping is normal.Caution: only when there is special and abnormal condition, can the emergency stop button be pressed manually to stop the unit emergently. After faults are eliminated, if it is necessary to re-start the unit, the unit should not be started up until after 60 seconds the system pressure is unloaded completely.Caution: the parameters of the compressor unit are set in the factory before it is delivered. Please contact our company if the parameter setting must be changed under special conditions, or otherwise the user should take responsibility for possible serious consequences.4. Normal Operations(1) Preparations before startup: check the oil level in the air-oil separator and slightly open therelease valve under the air-oil separator, in order to drain the possible condensate water accumulating in it. Make sure that no condensate water exists in the separator and then tighten this valve, and open the valve at air supply opening of the compressor.(2) Start up: Switch on the power supply, and press the “ON” key on the instrument panel, andthe compressor starts operation. If air discharge pressure must be adjusted, please gradually adjust the valve at air supply opening of the compressor to smaller opening.(3) Stop operation: Press the “OFF” key on instrument panel, and the compressor starts tooperate at unloading for some time and then come to a stop. If the compressor is not used, switch off the power supply and close the valve at air supply opening of the compressor. [Cautions]Warning: The compressor will stop automatically if it runs at no load for a long time.When this happens, never start any check or repair work, as the compressor will resume operation at any time. The compressor unit with separate fan, can automatically control the operation and stop of its fan, so please never touch the fan, in order to avoid personal injury. The power supply must be disconnected before checks!Warning: after power supply is switched off, the compressor will suddenly stop operation. In this case, remember to disconnect the power supply of compressor, so that the electrical control part will not be burnt in the event of sudden power-on.Besides, there may be other hidden risks.Chapter VII Maintenance1. Maintenance Interval and Items of Screw CompressorMaintenance Interval Operating Hours (h)Maintenance Items Daily 8 Before startup, drain the condensate completely and check whetherthe oil level, indicators on the operation panel or the indications onthe text display are normal, and the readings of the timer iseffective, and also check the differential pressure gauge andtemperature.Weekly 80 Check the leakage and clean the unit. Check if there is any abnormal noise.Every three months 500 Carry out first oil change after new compressor runs in, replace theoil filter, and carry out the maintenance according to the indications of the maintenance indicator on the air filter dependingon the operating conditions2000 Manually check the safety valve, clean the cooler, replace theelement of air filter, replace the oil filter, change the oil, check the thermometer, refill lubricants into the motor, and test electricalcontrol system.3000 Replace the element of oil-gas separator, check belt tension according to the type of the belt drive (replace the belts if the tension is beyond adjustable range), and check the tightening ofmoving parts.Every year 4000 Check if the temperature control valve works normally. Check allthe connections of oil and air pipelines. Check the adjustment ofpressure switch. Check if emptying operation is good.Note: Above-mentioned maintenance intervals depend on actual operating conditions and operational performance.2. Specification and Application of Lubricating OilPlease refer to the motor operating instructions for the refilling and change periods of lubricating greases of motor. In general, the motor bearing must be filled with grease every 2000h operation of the motor. Greasing points are marked on the motor, and users should refill designated grease correctly as required in the operating instructions. Use of the greases of different brands will reduce the service life of the motor. Note: make sure that no contaminants are mixed with the grease during grease refilling. Grease of proper quantity should be added. Refilling excessive grease will cause damages to the bearing.Lubricating oil (grease) has decisive influence on the performance of the complete oil-sprayed screw compressor unit. If improper or incorrect oil (grease) is used, serious damage will be caused to the compressor. Therefore, following regulations must be observed:2.1 The oil product should comply with related requirements. Never use the lubricating oils (greases) of different brands and types together. It is strictly prohibited to use counterfeited oils or reclaimed oils. The brand of lubricating oil (grease) to be filled is specified in the factory’s document supplied with each compressor.2.2 The oil (grease) has following performance requirements: excellent anti-oxidizing,。

3-2清洗机身润滑系统1. 将所有检查盖板从机身取下,以便能仔细检查内部,发现诸如灰尘和碎屑残渣之类在压缩机安装时介绍过的待清除物。

注意出厂时对润滑系统涂附的防锈层用推荐的润滑油可溶解,除非已被污染,否则防锈层不必除去。

但是贮油箱和油管,包括冷却器和过滤器,必须排净任何滞留的防锈物。

2. 如果必要使用安全溶剂清洗机身,用不起毛的布,而不是用破棉布,将其擦干。

开灯检查拐角、凹槽和其它可能藏污纳垢之处是否洗净。

机身内部已油漆过,便于检查灰尘;当清洁机身内部时不要括掉和用砂皮磨掉防油漆。

3. 在主轴承润滑油端盖入口侧安装一块100目的滤网(为了加强,用30目滤网支衬)。

4.脱开主轴承和十字头滑道供油跨接管道,(这样做是为了避免清洗过程中润滑油将杂质带入运转面)。

将不起毛的细棉布袋盖在各断开的油路端。

5.清洗油在常规操作温度下,必须比使用油粘度低。

推荐使用加热到近65℃的SAE-10油。

清洗油泵的流量必须比由轴头泵或由电机单独驱动的油泵,提供的正常流量大至少10%。

6.曲轴箱加油到稍高于装在机身油泵端油标显示的油面。

在清洗时不可运转压缩机。

但压缩机每隔30分钟宜进行盘车,以保证所有的表面都可被清洗到。

7. 使用清洗油泵,吊到与主油泵和辅助油泵平行,清洗油通过系统打循环。

8. 清洗系统直到通过润滑油的压力降接近0.1Mpa,然后放油到可以取下过滤嚣罩,打开清洗过滤嚣罩,并根据操作手册装上新的过滤器元件。

9. 继续清洗系统4至5小时,然后取下100日网罩和细棉布袋,清洗或调换它们。

10.继续清洗系统6至8小时,取下、清洗、重安装100目滤网。

取下旧的细棉布袋并装上新的。

11.重复第10步直到100目滤网和细棉布袋保持干净为止。

12.第11步完成时,取下100目,30目滤网罩及细棉布袋,重接好所有的内部润滑油管。

13.继续清洗系统至少2小时,排干储油池,擦净并重新注入所需数量的推荐用油。

14.安装新的油过滤嚣元件。

15.从机身及远离泵排出的中体上取下检查盖板。

启动辅助油泵,预润滑压缩机,直到油明显地流至最后一个十字销和衬套、十字头滑履、主轴瓦和连杆轴瓦。

16.当油能从十字销处观察到时,关掉泵,安装新的垫片(如有损坏)并重新装上检查盖板。

3-3冷却水要求冷却水供应必须过滤到125微米,并经过处理以免腐蚀或堵塞填料盒中的水通道。

每个填料组件建议最小供水量为191/min,低于32℃。

整个运行过程都需要冷却水。

填料盒需要小O型圈以密封水通道;这些O型圈必须正确安装和维修,保证状态良好以防泄漏。

3-3.1充水冷却系统当所有的冷却水管道连接好后,打开冷却水回路。

根据工作专门图表所有的流量控制阀都宜处于全开状态。

当往冷却水系统内注水时,打开放气阀,将气缸水夹套和热交换器中的气体排出,这一点很重要。

通过现场安装的小流量指示器验证冷却水流量。
