电液转换器工作原理

电液转换器工作原理
电液转换器是一种将电能转换为液压能，并实现机械动作的装置。

它由电动机、泵、阀门等组成，其工作原理如下：
1. 电动机：电动机通过电能将电能转换为机械能，驱动泵的运转。

2. 泵：泵是电液转换器中的核心组件，负责将液体从低压区域抽送到高压区域。

当电动机驱动泵旋转时，泵将液体吸入并通过出口压力流向系统。

3. 阀门：阀门用于控制液体的流动和转换流向。

通过控制阀门的开启和关闭，可以实现液体的流向控制和压力调节。

4. 液压缸：液压缸是电液转换器的输出机构，负责将液压能转换为机械运动。

当液体通过阀门进入液压缸，液压缸内的活塞受到液压力的作用而产生线性运动。

总体而言，电液转换器通过控制电动机的运转，驱动泵将液体抽送到液压缸中，通过阀门的开闭控制液体的流向和压力，从而实现机械运动的控制。

When additional information is desired to satisfy a problem not covered sufficiently for the user’s purpose, please contact your Cooper Power Systems sales engineer.CAUTION:DO NOT ENERGIZE THISEQUIPMENT OUT OF OILSHIPMENT AND ACCEPTANCEEach switch is completely assembled, inspected, adjust-ed, and tested at the factory and is filled to the correctlevel with insulating oil.It is in good condition whenaccepted by the carrier for shipment.Upon receipt, inspect the switch thoroughly for damageand loss of parts or oil incurred during shipment.If dam-age or loss is discovered, file a claim with the carrierimmediately.Save the shipping carton or crate—with allpacking— for inspection.Check for oil leakage and tighten all bolts that may haveloosened during shipment—especially the bolts attach-ing the head to the tank.STORAGE If the switch is stored for any appreciable time before installation, provide a clean, dry storage space in an area where the possibility of mechanical damage—especially to the bushings—will be minimized.2Figure 2.Lifting a Type TSC oil switch.Table 1Ratings and SpecificationsDESCRIP TIONThe Cooper Power Systems T ype TSC switch is a three-phase oil-filled device designed specifically for capacitorswitching applications on 20/34.5-kv distribution sys-tems.With a capacitive switching current rating of 135amps and momentary and latching ratings of 12,000asymmetical amps, the TSC switch can switch capacitorbanks rated up to 6000 kvar.The TSC switch is equipped with a simple, fast-responsemechanism that switches all three phases simultaneous-ly from a common shaft operated by the release ofpreloaded springs.Double-blade moving contacts,mounted directly to the shaft, are rotated in 90-degreeincrement into and out of springloaded, finger-type sta-tionary contacts.The fast rotating action provides con-tact opening and closing times of about five-eighths ofone cycle.The operating springs are preloaded by anelectric motor and reduction gear device to the point ofrelease to provide this fast rotating action.T otal operat-ing time for the motor to load and release the springs foreither an open or a close operation is 15 seconds maxi-mum.A solenoid-operated clutch engages the motordrive to the operating mechanism.The TSC switch may also be manually operated by asingle, downward pull of the manual operating handlewhich is located under the sleet hood at the front of theswitch.Nominal system voltage (kv rms} . . . . . . . . . . . . . . . . . . .34.5Rated maximum voltage (kv rms) . . . . . . . . . . . . .

switch tank is at the proper levelby checking the dipstick in the head casting.Replenishany loss with new, dry, transformer oil.If the switch has been stored for any length of time or is being relocated, check the dielectric strength of the oil in accordance with ASTM-approved testing procedures.For the physical properties of the oil used in Cooper Power Systems distribution switchgear, see Reference Data R280-90-1.1.In new equipment, the oil must have a minimum dielectric strength of 26 kv.If less than 26 kv, filter the oil to restore its dielectric strength to an acceptable level.2.If the equipment has been in service and is being relocated, the minimum dielectric strength of the oil must be at least 22 kv.If less than 22 kv—or if the oil is contaminated with carbon sludge—replace the oil.About 35 gallons of oil are required to fill an empty tank to the correct level.LIFTING A SWITCH Follow all approved safety practices when making hitches and lifting the equipment.Lift the load smoothly and do not allow the load to shift.The T ype TSC switch has two lifting lugs—both must be used when lifting the switch.Maximum strength is attained with a vertical lift attached to the e a spreader bar with a fixed attachment point for the hook at the load center.If a sling is used for lifting a TSC switch, it must have a fixed attachment point at the load center.Rig the switch so that the sling height is equal to—or greater than—the distance between lifting lugs.S260-20-103Figure 3.Direct-pole-mounting hanger KA2TSC1.Figure 4.Capacitor-structure-mounting hanger KA2TSC2.NOTE:Dimensions shown are for general information only.For critical construction dimensions, refer to factory.MOUNTINGThe T ype TSC switch can be easily installed using spe-cially designed pole-mounting or capacitor structure-mounting frames.A windlass-type hoist is also availablefor both frames to facilitate inspection and maintenanceof the switch.Instructions for the assembly and installa-tion of the mounting frames are furnished with the frames.Essential dimensional information for these installations is shown in Figures 3 and 4.Outline dimensions for the TSC switch are shown in Fig-ure 5 to accommodate any custom-built mounting instal-lation.4Figure 5.Outline dimensions for the Type TSC oil switch.Figure 6.Connection diagram—standard Type TSC switch.Figure 7.Control plug—standard Type TSC switch.CONNECTIONSMain WiringPrimary connections to the TSC switch are made at the universal clamp-type bushing terminals that accommo-date either copper or aluminum conductors from no.6solid through 350 mcm in a vertical or horizontal posi-tion.Control Wiring—Standard Switch The control circuit is permanently wired to an 8-pin receptacle in the switch head casting.The mating plug is furnished as standard with the switch.Internal connections to the receptacle and customer connections to the plug are shown in Figure 6.Pinarrangement for the plug is shown in Figure

电液转换器工作原理

电液转换器工作原理
电液转换器是一种将电能转化为液压能的装置，通常用于控制液压系
统的动作执行机构。

其工作原理可以简单描述为：通过电控信号控制电磁
阀的开关，使得液体能流通或截断，从而达到控制液压执行元件（如液压缸、液压马达等）运动的目的。

1.电源供电：电液转换器通过外部电源提供所需的电能，一般为直流
电源。

2.控制电磁阀：电磁阀是电液转换器的核心部件，其通过电磁力控制
阀芯的开关状态。

当电磁阀闭合时，阀门被打开，液体能够从液体进口进
入液压执行元件，执行元件开始运动；当电磁阀断开时，阀门关闭，液体
流通被截断，执行元件停止运动。

3.液压执行元件：液压执行元件是电液转换器输出的动力部分，它接
受液压能的驱动以完成工作。

常用的液压执行元件包括液压缸和液压马达。

当电磁阀控制液体流进液压执行元件时，液压执行元件受到压力作用而发
生相应的运动，如液压缸的伸缩、液压马达的旋转等。

4.油箱：油箱是电液转换器中的液压容器，用于储存液体以及散热降温。

油箱中通常配有滤芯、冷却装置等，以保证液体的质量和温度。

通过
油路的设计，液体能够顺利地从油箱中流出、进入液压执行元件，形成闭
合的液压系统。

综上所述，电液转换器的工作原理主要是通过控制电磁阀的开关状态
来实现液体的流通和截断，并通过液压执行元件将液压能转化为机械能。

通过电源供给电能，使得电磁阀的开关控制能够根据需要进行动态调整，
从而实现对液压执行元件运动的精确控制。

电液转换器被广泛应用于液压
传动系统的自动化控制、工程机械等领域，提高了系统的灵活性和精确性。

sva9-n电液转换器

-N型电液转换器型号：SVA9--N 价格：18000.00使用说明书SVA9-N 型电液转换器是专为汽轮机电液调速器开发的关键电－位移转换元件，它能把微弱的电气信号通过液压放大转换为具有相当大作用力的位移输出。

SVA9-N型电液转换器主要由动圈式力马达、控制滑阀及随动活塞三大部分组成，控制滑阀与随动活塞之间采用直接位置反馈，安装方式采用板式连接。

SVA9-N型电液转换器是SV9型电液转换器的改进型，是我公司应用户要求改制的抗污染型电液转换器，它针对电站行业对电液转换器工作须绝对可靠的要求，在SV9型基础上改进零部件材质、提高加工精度，加大动圈出力，并在进油口处增设可反吹冲洗、反复使用的高效过滤器。

与SV9相比，抗污染能力更强，工作更可靠，是更适合于电站行业应用的新一代电液转换器。

除电气参数不同外，在连接尺寸上它与SV9完全一致，可以方便地替代SV9而不需对调速器作任何改动。

SVA9-N型电液转换器结构精密，工作可靠，灵敏度高，动特性好，对油液洁净度要求较低，在NAS8级的油液中能长期稳定地工作，除此之外，还具有液压应急控制功能，只要通过一个二位四通阀把进出油口（Ｐ、Ｔ）换向或在进出油口（Ｐ、Ｔ）同时通入压力油，随动活塞就能立即下推到底。

一、工作原理SVA9-N型电液转换器的电气――位移转换部分采用了动圈力马达结构，液压放大部分采用了具有直接位置反馈的三通控制滑阀控制差动缸（随动活塞）的典型结构。

其工作原理如下：磁钢在气隙中造成固定磁场，当动圈绕组中有控制电流通过时，动圈在气隙磁场中受电磁力的作用，此电磁力克服弹簧力使动圈及控制滑阀产生与控制电流成正比例的位移。

压力油从Ｐ口进入，流经控制滑阀与随动活塞的上下可变节流口，由Ｔ口回油。

油源压力直接作用在随动活塞下腔，使之始终有一个向上的恒力，而上下节流口间的控制油压则作用在随动活塞上腔（被控腔），使之产生一个向下的推力。

随动活塞上腔面积设计成是下腔面积的两倍，因此当控制滑阀静止时，随动活塞自动地稳定在一个平衡位置，在这个位置上，上、下节流口的过流面积相等上腔控制油压刚好等于下腔油源压力的一半，使作用在随动活塞两端的液压推力相等。

It does not refer toor indicate a dangerous situation.2.2Proper useThe I/H converter serves to transform an electric set signalinto a related hydraulic output pressure reduced to feed-in pressure. Thisallows, for example, adjusting control pistons at hydraulic cylinders whichare used to position the valves of steam turbines.The I/H converter is suitable for usage in potentially explosiveatmospheres according to the explosion protection mentioned inchapter 1.2.3Important notesThe following notes refer to the entire instruction manual and have to beobserved in addition to the individual notes.Accident prevention·In any case observe the relevant standards and regulations when connecting an I/H converter in ex-design.·Improper use may cause operating agent under pressure to leak at the sealing surfaces. There is a risk of fire around hot components.·Isolate the hydraulic supply prior to working on the I/H converter.05 / 03cet - Ochs Voith Turbo GmbH & Co, KG Page: 6 / 20·Failure of electric power or disturbance of the control electronics integrated in the I/H converter may cause strong variations of theoutput pressure when operating the I/H converter. Thus e.g. thepiston rod of a hydraulic cylinder may move uncontrolled, causing danger to individuals or equipment.·During operation, the outer surfaces of the I/H converter may heat up due to the pressure fluid. Contact may cause skin burns. Make sureto cool down the I/H converter prior to working on it.·Electrical components are installed in the I/H converter. These components can be destroyed by e.g. welding in its surrounding.Therefore make sure to disconnect all electric connections prior toelectrical weldings in the surrounding of the I/H converter.Environment protection·During mounting, dismounting or improper use of the I/H converter pressure fluid may leak out. Operating agent reaching the sewagesystem or the open soil, causes severe environmental damages.Leaking pressure fluid has to be collected and deposited inaccordance with the national legal regulations.Instruction manual·The instruction manual contains important information for proper handling of the I/H converter. Prior to installation and commissioningof the I/H converter, read the manual carefully and make sure it iscompletely understood.·Keep this manual in a location convenient to the operating staff.·In addition to this operating manual: Have the relevant regulations for prevention of accidents and environmental protection available andobserve these.05 / 03cet - Ochs Voith Turbo GmbH & Co, KG Page: 7 / 2005 / 03cet - Ochs Voith Turbo GmbH & Co, KGPage: 8 / 20Staff qualification· Only trained and instructed staff is allowed to perform any work on theI/H converter.

KG, Crailsheim.Repair works on the I/H converter are to be performed or approved by Voith Turbo GmbH & Co. KG, Crailsheim.05 / 03cet - Ochs Voith Turbo GmbH & Co, KGPage: 9 / 203.Function3.1DesignFig. 3.1.11 – Control magnet VRMP - Input pressure2 – Tappet for power transmission P A - Output signal pressure3 - Potentiometer X0 und X14 – Manual operation knob T 1- Tank return line5 – Electric connection T 2- Tank return line int. leakage6 – Control housing F Mag - Magnetic force7 – Control piston F Hyd - Hydraulic force8 - CoverF Fed- Spring force9 - Control spring3.2 Operatingcharacteristics(see fig. 3.1.1)A set signal w = 0/4...20 mA generates a magnetic force F Mag in theVRM, the limits of which can be adjusted by means of the X0 and X1potentiometers and which is then transmitted onto the control piston viatappet.The hydraulic force F Hyd being proportional to the output signal pressureP A acts against this force.In the case of the two forces being equal, the control piston is positionedin the “hydraulic center” as shown in fig. 3.1.1 and the output signalpressure P A corresponds to the set signal. In the “hydraulic center“position the control piston performs minimum oscillating movements inthe area of the guiding edges P®P A and P A®T , in order to keep theoutput pressure P A on the value set by F Mag.When increasing the set signal and thus F Mag from this condition, thecontrol piston position changes and thus connects the output pressure P Ato the feed pressure P in and blocks P A towards the tank return line T1.Now the pressure P A will increase until the control piston returns to the”hydraulic center“ and P A corresponds to the new set signal.The spring force F Fed of the control spring generates a force-offset inorder to guarantee the I/H converter function for output pressures ofapprox. 0 bar, too.The internal leakage is fed back via tank return line T2.Function of manual operation knobThe control magnet of the I/H converter is provided with a manualoperation knob, by means of which an adjustable spring force can be setinstead of the magnetic force F Mag . This spring force affects the controlpiston via magnet armature and tappet. The hydraulic force F Hyd , beingproportional to the output signal pressure P A also acts against this springforce here. Thus adjustment of output pressure is possible withoutelectric connection.4.Packing, Storage and TransportPackingThe I/H converter is delivered in a special packing.The openings for the hydraulic connections are sealed with plugs toprevent penetration of impurities and humidity.Storage and preservingThe outer surfaces of the I/H converter are protected by means of apreserving surface coat.The internal parts are preserved by oil.Within Europe the anticorrosion protection is sufficient for approx. 8months in industrial air, presuming storage of the I/H converter in a drylocation.In case the I/H converter is supposed to be stored for a longer period oftime, special precautions will have to be taken.In each specific case, these precautions have to be agreed withVoith Turbo GmbH & Co, KG, Crailsheim.The storage ambient conditions have to be within the limits as indicatedin chapter 1.TransportImproper transport may cause personal injuries and damages toproperty.Pack the I/H converter in a way that prevents housing damages duringtransport. In particular make sure that no compulsive forces affect theelectric cable fitting and the electric feed in cable are not kinked ordamaged. Do not hold the I/H converter at the electric feed in cable fortransport.5.Installation·Improper installation of the I/H converter may cause malfunctions and premature failure of the operation of the I/H converter.·Cleanliness is imperative during installation an connection. Prevent that any impurities ( dust, metal chips etc.) can get into the I/Hconverter or pipe system which may cause damage to the I/Hconverter.Cover and protect the I/H converter and in particular the electric linesduring construction time.5.1MountingPerform any work on the I/H converter only when it is in deenergizedcondition and with switched off oil supply system.Protect oil and power supply against unintentional switching-on duringmounting.Install the I/H converter in accordance with the permissible installationposition as shown in chapter 10.Recommended fastening bolts:2 pieces hexagonal screws M10, strength category 8.8.tightening torque MA=35 Nm, thread slightly oiled.Select screw length according to mounting situation.connection5.2 HydraulicThe hydraulic connection on the I/H converter is made by means ofconnection bores at its bottom. The connection flange is sealed witho-rings. Please refer to chapter 10 for position and dimensions of theconnections.Surface roughness of connecting flange:Ra = 1.6 m m, Rmax = 6.3 m mOnly pressure-less return of the operating medium through the return lineT2 to the tank, ensures proper work of the I/H converter.In practise the tank lines for the connections T1 and T2 are joinedtogether and laid downgrade towards the tank in one common pipe line.Requirements to this pipe line:Nominal size 20 mm or bigger for I/H converters with an output pressureup to 10 bar.Nominal size 30 mm or bigger for I/H converters with an output pressureof more than 10 bar.Observe the correct pressure range when selecting pipes, hoses,screwings and flanges.Immediately replace damaged pipes and hose lines.When assembling the pipe lines, ensure that it is fastened to fixedstructures, free from vibration and not to moving equipment. Temperaturevariations of the piping (thus alterations in length) must not applyconstraining forces to the I/H converter.Clean pipe lines from dirt, cinder, sand, chips etc. prior to installation.Pickle or flush welded pipes.Clean and flush carefully all pipe and hose lines prior to attaching theI/H converter.=> For flushing, a flushing plate (Art. No. 43.8565.10) is available.See chapter 11.=> To connect the I/H converter to the piping system an adapter (Art. no.43.9300.11) is available. See chapter 11.·Residual oil may leak when removing the plug (max. 0,1 l). Collect the oil in a suitable container and deposit it properly.·Do not use fibrous or hardening sealing compounds, such as e.g.hemp or mastic to seal the connections and screwings.5.3Electric connectionThe electric system has to be connected in accordance with electricalengineering standards and legal regulations of the manufacturingcountry. The works have to be performed by an electric specialist withexperience and knowledge in explosion protection.When connecting the I/H converter within the explosion hazardous area ,the electric feed in line have to be connected in housings according toprotection type EN 50014, section 1.2.When connecting customer´s lines, avoid parallel run of the I/H converterlines with the lines of current converter assemblies.The customer`s signals and supply lines running to the I/H convertermust be screened.Please refer to chapter 10 for the wiring diagram.missioningThe I/H converter was adjusted and tested at Voith Turbo’s works bymeans of the potentiometers X0 and X1. The test result is documented inan attached test certificate.The potentiometers are provided with a protective cap to avoidunintentional maladjustment and impurities.6.1Test runMake sure that pipe lines and hydraulic system are cleaned prior toperforming a test run. The operating fluid has to be in accordance withthe purity class as indicated in chapter 1. Do not flush or clean thepressure fluid with the I/H converter being hydraulically connected.Operation of the I/H converter with contaminated pressure fluid is notpermitted, the I/H converter may be damaged.·Check the line mounting, connection and flow direction to and on the I/H converter.·Check the electric connection.·Switch on the 24 VDC power supply.·Switch on the oil supply and check input pressure.The minimum input pressure has to be 1.5 bar more than the maximumoutput pressure required at 20 mA.·Set the signal w = 0/4.. 20mA and check output pressure.During the test run, check all hydraulic connections for leakages. Incase of leakage, immediately switch off the hydraulic supply andeliminate leakages.6.2Parameter settingDue to unintentional maladjustment of the parameters or changedoperating conditions, new setting of one or both parameters may becomenecessary.We recommend to document adjustment of the parameters as well as theset values.The parameters are adjusted by means of potentiometers X0 and X1.Please refer to chapter 10 for the position of the potentiometers.Potentiometer effects:X0-With help of potentiometer X0 the minimum output pressureP A min is adjusted at a setpoint of 0 mA or 4 mA.Pressure increase by turning the potentiometer clockwise.X1-With help of potentiometer X1 the maximum output pressureP A max is adjusted at a setpoint of 20 mA.Pressure increase by turning the potentiometer clockwiseX1 should be adjusted before X0.The X1- adjustment influences the adjustment of X0.Manufacturer-provided adjustments:At the works, the I/H converter has been adjusted as indicated in theorder.7.Operation7.1 Operation with manual knobOperation with manually controlled rotary knob is possible without electricenergy.On operation with manually actuated rotary knob, uncontrolled strokemovements of the hydraulic components controlled by the I/H converteroutput might occur due to the increase in the output signal pressure.Manual operation is only possible when the circlip is removed from themanual operation knob.On completion of operation with manual operation knob, move themanual operation knob in its final position by turning it counter clockwiseand pushing in the circlip to its final position.·Remove the circlip.·Slowly turn the manual operation knob clockwise and observe the output pressure.Effective direction: Output pressure increase by clockwise rotation.7.2Operation with set signalWhen the supply voltage is switched on, the output signal pressure canbe adjusted continuously by the set signal 0/4...20 mA within the limitsset by the potentiometers X0 und X1.7.3Trouble shooting and remedial actionPrior to all works, make sure that the I/H converter was commissionedaccording to chapters 5 and 6.Malfunction: Pressure variationsThe output signal pressure P A may vary now and then orperiodically with low or high frequency and amplitude.Cause: 1. air inclusions in the hydraulic component2. low or considerably varying input pressure.3. dirt particles in the hydraulic component4. pressure on return lineRemedy: 1.On first commissioning air inclusions in the VRM may causepressure variations. Due to periodic setpoint changes(approx. 0.5 Hz) of approx. +/- 6 mA, the air will escape outof the VRM after some minutes causing the hydraulicdamping to become effective.2. Under load and in particular in case of higher outputsignal pressure, a lower input pressure may lead topressure variations.Increase and / or stabilize the input pressure by takingappropriate measures (e.g. accumulator). See also chapter1.3. Contaminated pressure fluid results in increased friction atthe control piston, thus causing hysteresis and pressurevariations.Open hydraulic component and clean the inner elements. Incase of damaged surfaces and guiding edges replace theI/H converter.4. The dimensions of the return line have to be sufficient.In case of additional consumers of the output pressureconnected to this line, make sure they do not create anypressure in the return line. See also chapter 5.2.Malfunction:Output pressure PA ® 0 bar or ® P (input pressure)Due to a defective control valve VRM or blockage of thecontrol piston the output pressure may fall to 0 bar orincrease to the input pressure.Remedy:The function of the hydraulic component can be checked using the manually controlled knob with the supply voltage beingswitched off. See chapter 7.1.If the output pressure cannot be adjusted manually, the controlpiston, e.g., may be blocked by particles.Open hydraulic component and clean inner parts.If the surfaces and guiding lines are damaged, exchangethe I/H converter.Should output pressure adjustment be possible with manualoperation knob, but not with the control magnet, the controlmagnet VRM is defective.Repairs on the control magnet VRM are not allowed, otherwiseexplosion protection is no longer guaranteed.Replace any defective I/H converter completely.8.Maintenance and RepairFor a trouble-free and reliable operation of the I/H converter, it isnecessary to perform inspection, maintenance and repair work incertain intervals.Routine inspectionCheck the pipes, screw connections and connections on theI/H converter for leakage, impurities and damage.Eliminate any leakage, impurity and damage noticed, if required, duringappropriate operating modes.Monitor the control behavior of the I/H converter for any changes.Analyse and eliminate the causes, if required, during appropriateoperating modes.Inspection after approx. 740 operating hours / max. 1 monthTake an oil sample from the oil tank and analyse it for solid andsuspended matters, water content, shadings and air bubbles.Analyse oil purity of the oil sample. Clean or exchange the oil, ifrequired, in an appropriate operating mode.Inspection after approx. 8000 operating hours / max. 1 yearTake an oil sample from the oil tank and analyse it chemically.If required, clean or change the oil during an appropriate operating mode.Check and retighten, if necessary, the electric connections of the I/Hconverter.9.ShutdownIf the I/H converter is switched off for reasons of repair, inspection orunit shutdown, switch off the oil supply system and relieve all pressurereservoirs, if effective. Switch off the 24 VDC supply voltage andremove the lines as well as piping and hose connections. Doing so, anconsiderable oil quantity may leak out. Collect the oil in a suitablecontainer and deposit it properly. Close all holes. Now clean and packthe I/H converter.DisposalIn the event of disposal of the I/H converter, observe the local applicableregulations regarding the environmental protection. The I/H converteressentially contains steel, copper, synthetic materials, electroniccomponents and residual oil.Instruction Manual I/H Converter DSG-B03212I/H Converter DSG-B0721205 / 03cet - OchsVoith Turbo GmbH & Co, KG Page: 19 / 203.626 - 018861 en D – 74564 Crailsheim 10.Outline and Wiring DiagramInstruction ManualI/H Converter DSG-B03212I/H Converter DSG-B07212 11.AnnexFlushing plate43.8565.10Adapter plate43.9300.1105 / 03cet - Ochs Voith Turbo GmbH & Co, KG Page: 20 / 20 3.626 - 018861 en D – 74564 Crailsheim。

手摇或电动转辙机，检查道岔开口，两侧应基本相同，如相差较大时通过调整安装装置动作拉杆使两侧开口相差不超过3mm，然后检查道岔开口是否符合规定要求，若开口大于规定值时，在尖轨连接铁和尖轨间加调整垫调整。动作拉杆上每齿齿距为3mm。
道岔铺设完成经过检验、验收后，检查各牵引点处岔枕间距；检查牵引点中心线（基本轨上两孔中心）距前一岔枕中心线距离；检查牵引点基本轨两孔中心与尖轨安装连接铁的两孔中心是否对中。

SVA9电液转换器

S V A9-N型电液转换器
型号：SVA9--N
价格：18000.00
使用说明书
SVA9-N型电液转换器是专为汽轮机电液调速器开发的关键电－位移转换元件，它能把微弱的电气信号通过液压放大转换为具有相当大作用力的位移输出。

SVA9-N型电液转换器主要由动圈式力马达、控制滑阀及随动活塞三大部分组成，控制滑阀与随动活塞之间采用直接位置反馈，安装方式采用板式连接。

与SV9相比，抗污染能力更强，工作更可靠，是更适合于电站行业应用的新一代电液转换器。

除电气参数不同外，在连接尺寸上它与SV9完全一致，可以方便地替代SV9而不需对调速器作任何改动。

一、工作原理
SVA9-N型电液转换器的电气――位移转换部分采用了动圈力马达结构，液压放大部分采用了具有直接位置反馈的三通控制滑阀控制差动缸（随动活塞）的典型结构。

其工作原理如下：
磁钢在气隙中造成固定磁场，当动圈绕组中有控制电流通过时，动圈在气隙磁场中受电磁力的作用，此电磁力克服弹簧力。

电液伺服阀VS电液转换器

一、如何将电子调节器输出的“电”信号，转换成能被液压执行器接受的“液”信号，让液压执行器按照电子调节器的要求调节进汽调节阀开度，改变汽轮机进汽流量？答案就是电液转换器，它是将“电”信号转换成“液”信号的中间媒介，是整个电液系统中的关键部件。

二、电液转换器的工作原理及分类按照电液转换器的工作原理，它由力矩马达和液压放大两部分组成。

力矩马达的作用是将“电”信号转换成机械力或机械位移信号，而液压放大部分则将机械信号进一步放大并以“油压”或“流量”的“液”信号形式输出。

力矩马达利用电动机原理，将磁场中通电线圈的电流转换成机械力，并以通电线圈或磁铁产生的机械位移输出。

从线圈位移输出还是磁铁位移输出来分，力矩马达有动圈式和动铁式两种基本类型。

电液转换器的液压放大部分，从“液”信号输出的形式来分又有“油压”输出和“流量”输出两种形式。

从电液转换器供油压力等级来分，又有高压电液转换器和低压电液转换器两种。

目前，高压电液转换器的供油压力为13~14Mpa；低压电液转换器的供油压力为1Mpa左右。

三、电液转换器目前有多种结构形式动圈式力矩马达用十字片弹簧平衡的电液转换器；动铁式力矩马达带二级液压放大的电液伺服阀；动铁式力矩马达直接动作的直动式电液伺服阀；动铁式力矩马达采用碟阀控制的电液转换器。

这里介绍的是上海汽轮机厂采用比较多的动铁式力矩马达带二级液压放大的电液伺服阀和动铁式力矩马达采用碟阀控制的电液转换器。

习惯上，我们把“油压”输出的称为电液转换器；把“流量”输出的称为电液伺服阀。

1、动铁式力矩马达带二级液压放大的电液伺服阀：电液伺服阀是二战期间由于飞行器等军事装备对控制系统提出快速响应以及更高的动态精度要求而发展起来的，并在战后逐渐用于民用和工业设备。

它是一种能接受模拟量的“电”信号输入，并随电控信号大小和极性的变化，以“流量”或“压力”作为输出的液压控制阀。

常用的电液伺服阀带有两级液压放大器。

第一级液压前置放大器有滑阀、喷嘴挡板阀和射流管阀三种形式，喷嘴挡板型是常用的选择，而第二级液压功率放大器则无一例外地都采用断流式四通滑阀。
