汽轮机油系统的精讲
汽轮机油系统的精讲1 、典型油系统介绍汽机的油系统按功能可以分为：调节油部分，保安油部分，润滑油部分。
汽轮机的油系统是一套分厂完整的液压油系统，其组成：储油装置-油箱，动力单元-油泵，输送装置-管道，冷却单元-冷油器，净化单元-过滤器，控制单元-电调装置，执行单元-油动机。
下面以电调式汽轮机油系统为例分别来介绍：1 调节油系统电调型汽轮机通过电子调节器(即DEH)输出电信号，经过电液转换装置，改变成液压信号，控制油动机动作。
目前国内小型汽轮机用的电液转换器主要有三种分别是：VOITH,CPC,DDV(MOOG)。
作用是将接收到的电信号转换成相应的液压信号。
动力油(EH油)从注油泵出其中一路进入电液转换器，经过电液转换器变压后，成为调节油，进入错油门底部，控制错油门阀芯移动，改变动力油进入油动机活塞的油路，进而改变油动机活塞的位置。
油动机能够在一个特定的位置挺住，电调系统需要感知油动机目前的位置，这就需要有反馈信号的存在。
2 润滑油系统动力油来自主油泵出口，经过一射油器后，形成一股较低压力的油，这股油经过冷油器冷却至40℃(该温度下油的粘度最佳，工程实践中一般要求油温在40~45℃)后直接进入各个轴承，在转子轴颈和轴瓦之间形成一层油膜，起到润滑作用，同时，通过油将轴承处产生的热量带走。
3 保安油系统保安油系统，顾名思义，对汽轮机的起到安全保护作用的一股油。
保安油是由一股动力油在经过危机遮断装置后形成的。
保安油在汽轮机运行中，几乎不消耗油量，保安油压力与动力油一致。
只有当外部原因促使危机遮断装置动作，或者AST电磁阀动作，将保安油卸掉，保安油失压，使得汽轮机保安设备动作，起到关闭和保护汽轮机的作用。
例如汽轮机的主汽门液压缸上就接有保安油，当保安油失压后，主汽门会迅速关闭以切断汽轮机进汽。
2 、润滑油系统的组成系统主要由汽轮机主轴驱动的主油泵、冷油器、注油器、顶轴油系统、排烟系统、集装油箱（主油箱）、润滑油泵、事故油泵、密封油备用泵、滤网、电加热器、阀门、逆止门和各种监测仪表等构成。

电液转换器原理与调试
电液转换器原理与调试
电液转换器工作原理：（见图）
当信号电流I为零时, 芯棒M与滑阀O处于左端极限位置, 压力油腔P与控制油压A之间节流口关闭。
A腔经阀芯中的内孔与回油腔相通,所以A腔处于卸压状态。
当信号电流（I=4~20mA）增加时，芯棒M在磁场作用力下，或比例地产生一个向右作用力F，推动滑阀O向右移动，使控制油腔A与回油腔T的流通面积减小，与压力油腔P的流通面积增大，根据流量平衡原理，控制油压A升高，随着油压A 的升高，与A油腔相通的N腔压力也升高。
当产生的油压力f与F相抵消时，滑阀O达到平衡，控制油压A稳定。
A腔油压值即是成比例地对应输入信号的相应值。
当信号电流减小时，芯棒M在磁场作用力下，产生一个向左作用力F。
这时，由于与A油腔相通的N腔油压力大于芯棒作用力，滑阀O向左移动，使得控制油腔A与回油腔T的流通面积增大，与压力油腔P的流通面积减小，控制油压A降低。
同时，N腔油压亦降低，芯棒上的磁场力与油压力相等，滑阀达到平衡，控制油压A稳定。
在手动工作状态，旋动手轮，经传动杆K推动芯棒M移动，即能调到所要求的控制油压A。
一般对应4－20MA控制电流输出的二次脉冲油压A为0.15-0.45Mpa ,在这一段范围内控制特性的线形度较高。

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。

Flow Switch Series FSW-9000产品说明书
B-83Series are made with 316 SS and the standard enclosure is glass-filled nylon. The FSW-9000 Series can be made with a great variety of process connections such as threaded, flange, orsanitary and is also available in an aluminum enclosure for hazardous environments. Intrinsic safetybarriers required for explosion proof areas.Measuring Ranges for FSW-9000 SeriesThe FSW-9000 Series nominalmeasuring range is 0.04 to 2.0 m/s. The switch can be set to trip at any value in this range. To calculate the velocity for your application, use the following simple formula: V = 1.27 X Q D 2Q = Flow rate in meters per second D = Pipe internal diameter in metersV = Fluid velocity in meters per secondThe FSW-9000 Series is a flow switch monitor that measures the velocity of the flow. It is ideal for use in measurement and control liquid applications. The FSW-9000 Series provides two output options: a 4 to 20 mA analog output and a PNP/NPN output. For the 4 to 20 mA output, the electronics module converts the signal from the probe to a 4 to 20 mA analog output, which can be used to indicate flow rate. For the PNP/NPN output, the measured flow rate is compared to the setpoint value selected by the user and the switch changes state once the setpoint value has been achieved.The FSW-9000 Seriesmicroprocessor based electronics and unique self-calibration program gives the flow switch superior temperature compensation, a fast response time (adjustable from 3 to 10 seconds) and increased long term switch point stability.Even in the event of a power failure, the calibration program will store values for maximum and minimum flows for up to 10 years.A chain of 8 LEDs gives the user a visual indication of the flow rate as well as setpoint status, and one di-chromatic LED indicates switch point status. In addition, if there is a problem with the unit, the 8 LEDs will flash continuously providing troubleshooting information.The conical shape of the sensor’s tip means that the probe can be installed at almost any angle in the pipe and that if the probe is misaligned, accuracy will not be affected. The sensing element and connection of the FSW-9000Please note that the 4 to 20 mA option is scaled over 0 to 2.0 m/s The FSW-90-R is very similar to the FSW-9212 Series with one main difference: The sensor is separate from the electronics and it does not have an enclosed housing. This gives the FSW-90-R Series the ability to be installed in very small pipes and be remotely controlled by the FSCN-91 relay. The FSW-90-R Series is the ideal solution when there is not a lot of space to install even a compact unit or when there is a need for a mounted relay. In addition, the conical shape of the sensor’s tip allows the probe to be installed at almost any angle in the pipe, and if it is misaligned, accuracy will not be affected. The FSW-90-R is made with 316 SS. FSCN-91 relay can operate with DC or AC supply voltage and provides an analog 4 to 20 mA and SPDT output. The FSCN-91 enclosure is made with ABS and can be mounted on a DIN rail or by using 2 fixing screws.U H igh Reliability— No Moving Parts U 4 to 20 mA,PNP/NPN (Transistor), or Relay Output U E xcellent Low Flow SensitivityFSW-9212shown smaller than actual size.Liquid FLow TransmiTTer and swiTchFSW-9000 SeriesB-84BTo order ECTFE/ETFE element coating add suffix “-ETFE” to model number, for additional cost.

It does not refer toor indicate a dangerous situation.use2.2 ProperThe way valve serves to transform an electric set signal 4..20 mA into avolume flow variable in direction and size. This allows, for example, aninfinitely variable adjustment of a double-acting hydraulic cylinder toposition steam valves.2.3 ImportantnotesThe following notes refer to the entire instruction manual and have to beobserved in addition to the individual notes.Accident prevention•Improper use may cause operating agent under pressure to leak at sealing surfaces. There exists some risk of fire around hotcomponents.•Isolate the hydraulic supply prior to working on the way valve.•Failure of electric power or disturbance of the control electronics integrated in the way valve may cause strong variations of the outputpressure when operating the way valve.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 way valve may heat up due to the pressure fluid. Contact may cause skin burns. Make sure to cooldown the way valve prior to working on it•Electrical components are installed in the way valve. Thesecomponents may 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 way valve.Environmentprotection•During mounting, dismounting or improper use of the way valvepressure fluid may leak out. Operating agent reaching the sewagesystem or open soil, causes severe environmental damages. Leakingpressure fluid has to be collected and deposited in accordance withthe national legal regulations.Instruction manual•The instruction manual contains important information for properhandling of the way valve. Prior to installation and commissioning ofthe way valve, 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 same.qualificationStaff•Only trained and instructed staff is allowed to perform any work on the way valve. These personnel have to be trained and authorized tomount way valves professionally.•Installation, commissioning and operation have to be performed by an electronic expert.modificationsConstructional•Mounting and constructional modifications are not permitted.•The screwing of the cable inlet is secured against distortion. Do not distort or loosen the screwing.2.4 WarrantyThe terms and conditions mentioned in the General Conditionsof Sale of Voith Turbo GmbH & Co. KG, Crailsheim, are applicable.Warranty claims are excluded if these are due to one or several of thefollowing causes:• Improper transportation, storage, mounting, set-up, commissioning and operation of the way valve.•Not observing the safety instructions and guidelines included in this instruction manual.•Use of spare parts not approved byVoith Turbo GmbH & Co.

The essential control parameters are adjustable at the VRM from the outside using a potentiometer. This allows to optimally adjust control for various cylinders and to assign the required stroke to the set signal w.In the positioner, any deviation w-x will be multiplied with the KP-factor. The generated position controller output acts as set signal for the subordinate magnetic force controller. A force range for F Mag iscorrelated to the controller output range via the parameters F0 and F1, by means of which the control piston moves against the control spring into a defined end position. The end positions are in accordance with the respective greatest flow rate sections from P → A, B or from A, B → T.The position of the control piston as shown in figure 1 is designated ashydraulic center, where the cylinder is in a constant position s withoutany further movement. In order to prevent generation of the magneticforce required for the hydraulic center by deviation, the parameter FM isused to adjust a magnetic force-offset to zero deviation, thus the setsignal w is equivalent to the actual value s or x,.Manual control function:Instead of the magnetic force F Mag the manual control can adjust a forcewhich will be transmitted to the control piston by the tappet.Thus, the control piston is able to move without electric connection, andoutlet A or B can be connected with P.The system is able to run the piston rod of a cylinder connected at outletA andB into the relevant end position. It is not possible, though, to adjustany desired position s.4. Packing, Storage and TransportPackingThe way valve 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 way valve 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 way valve in a drylocation.In case the way valve 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 way valve in a way that prevents housing damages duringtransport. In particular, make sure that no compulsive forces affect theelectric cable fitting and that the electric feed-in cable is not kinked ordamaged. Do not hold the way valve at the electric feed-in cable fortransport.5. Installation•Improper installation of the way valve may cause malfunctions and premature failure of the way valve.•Cleanliness is imperative during installation and connection. Prevent any impurities (dust, metal chips etc.) from getting into the way valveor pipe system, which may cause damage to the way valve.Cover and protect the way valve and, in particular, the electric linesduring construction time.5.1 MountingPerform any work on the way valve only in deenergized condition andwith the oil supply system switched off.Protect oil and power supply against unintentional switching-on duringmounting.Mount the way valve according to the permissible installation position asindicated in Chapter 10.Recommended fastening bolts:2 pieces socket head screws M12, DIN 912, strength category 8.8.Tightening torque MA=70 Nm, thread slightly oiled.Select screw length according to mounting situation.connection5.2 HydraulicObserve the correct pressure range when selecting pipes, hoses,screwings and flanges.Immediately replace damaged pipes and hose lines.The hydraulic connection on the way valve 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 µm, Rmax = 6.3 µmWhen 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 way valve.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 theway valveAn adapter with connection threads G1/2" is available for connecting theway valve to hose or pipe lines.See chapter 10..•Residual oil may leak when removing the plug (0.3 l max.). 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.5.3 ElectricconnectionThe electric system has to be connected by some electronic expert, inaccordance with electrical engineering standards and legal regulations ofthe manufacturing country.When connecting customer’s lines, avoid parallel run of the way valvelines with the lines of current converter assemblies.The customer’s signal and supply lines running to the way valve must bescreened.Please refer to chapter 10 for the wiring diagram.6. CommissioningThe way valve was adjusted and tested at Voith Turbo’s works.The potentiometers are provided with a protective cap to avoidunintentional maladjustment and impurities.Make sure that the signal of the way return coming from the cylinder isdescending, i.e.: 0..100 % stroke correspond to 20..4 mA.run6.1 TestMake 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 hydraulically connected way valve. Operation ofthe way valve with contaminated pressure fluid is not permitted, the wayvalve may get damaged.•Check line mounting, connection and flow direction to and on the way valve.•Check electric connection.•Switch on 24 VDC power supply.•Switch on oil supply and check input pressure.In the beginning, lack of hydraulic damping may causeuncontrolled stroke movements at the actuator connected to outlet Aand B.If the installation position is correct, the included air will escape anddamping will become effective.•Enter setpoint w = 4.. 20mA and check reaction of theactuator connected to outlet "A" and “B”.•Run way valve until it is warm and check input pressure.•Enter setpoint w = 12 mA.Check the deviation between setpoint and actual remote indicationand, if necessary, correct hydraulic center using the FMpotentiometer.See chapter 6.2.1.•Vary setpoint w from 4..20 mA. Check stroke adjustment and, if necessary, adjust it using the X0 and X1 potentiometers.See chapter 6.2.2.In case that the cylinder piston to be positioned adjusts e.g. a steamvalve, make sure that in the 0%-position the valve stop is approached butnot the internal mechanical stop of the piston in the cylinder duringengaging.Otherwise the “closed position” of the valve is no longer granted.•Enter setpoint step-change in closing direction (e.g.: 18 → 6 mA).Check step-response and optimize it, if necessary, using the KP andTD potentiometers.See chapter 6.2.3.Check all hydraulic connections for leakages during the test run. In theevent of leakages, immediately switch off the hydraulic supply systemand eliminate all leakages.setting6.2 ParameterDue to unintentional maladjustment of the parameters or changedoperating conditions, a new setting of one or several parameters maybecome necessary.We recommend documenting any adjustment of the parameters as wellas the set values.The parameters are adjusted using the X0, X1, FM, KP and TDpotentiometers.description:Potentiometers: ParameterFM Adjustment of hydraulic center of the control pistonX0 Adjustment of position s at setpoint w = 4 mAX1 Adjustment of position s at setpoint w = 20 mAKP Adjustment of proportional gain of the positionerTD Adjustment of actual value differentiation of the positione rX0should be adjusted before X1.The F0 and F1 potentiometers are factory-set and are not to be adjusted.Please refer to chapter 10 for the location of the potentiometers.Unscrew 2 hexagon socket screws at the cover and pull it off in orderto reach the TD potentiometer.6.2.1 Center position adjustment of control pistonTo avoid any deviation between setpoint and actual position remoteindication, adjust an offset for the magnetic force using the FMpotentiometer. Select same to reach zero deviation at setpointw = 12 mA, and the control piston will be in the hydraulic center.Setpoint input w ≠ 12 mA may cause slight deviations as to the actualvalue remote indication.•Run way valve warm and check feed-in pressure.•Enter setpoint w = 12.00 mA using a power source.•Measure actual value remote indication and adjust it to12 +/- 0.05 mA using the FM potentiometer.Effective direction of FM:Clockwise rotation increases the magnetic force and the actual positionremote indication.6.2.2 StrokeadjustmentUsing the X0 and X1 potentiometers you can assign an effective piston stroke from a double-acting cylinder to setpoint 4..20 mA.The potentiometer settings have been determined differently: Operating range X0: +/- 5 %Operating range X1: +/- 5 %The data refer to the descending signal of way return20..4 mA ≈ 0..100 % stroke.0 % stroke adjustment:•Enter setpoint w = 4.0 mA using a power source.•Adjust 0 %-position using the X0 potentiometer and observe position s and the actual value remote indication.Should the actual value remote indication increase continuously, i.e. greater than 4 mA when adjusting the X0 potentiometer counterclockwise, then the lower mechanical stop (when adjusting the valve, usually the valve seat) is reached exceeding the control range. In order to safely reach the “closed position“ of a valve at a setpoint of 4 mA, even at thermal linear expansion or drifting of a signal, the stroke may also be adjusted at a setpoint of e.g. 4.5 mA.Effective direction of X0:Clockwise rotation moves the piston towards 100 %.100 % stroke adjustment:•Enter setpoint w = 20.0 mA using a power source.•Adjust the 100 %-position using the X1 potentiometer and observe position s and the actual value remote indication.Should the actual value remote indication decrease continuously, i.e. lessthan 20 mA, when adjusting the X1 potentiometer clockwise, then theupper mechanical stop is reached exceeding the control range.Effective direction of X1:Clockwise rotation moves the piston towards 100%.6.2.3 Adjustment of proportional gainThe control parameters at the way valve are factory-set.After mounting to a cylinder the control parameters need to be adapted toactual operating conditions at the site.•Enter setpoint step-change from 18 → 6 mA.•Observe time slope of the actual value x in the primary control.•Vary gain using the KP potentiometer until the time slope of the actual value corresponds to characteristic curve 2 in figure 4.Effective direction of KP:Clockwise rotation increases the proportional gain.Even if the closing and opening times seem to be sufficient with lowsetting of KP, it is necessary to adjust KP as described above.Benefit:Better dynamic behavior at minor setpoint changes and smaller deviationbetween setpoint and actual value remote indication.Following the optimization of KP, repeat setting of FM, X0 and X1, ifnecessary.Optimization by means of TD potentiometer is only allowed for trainedcommissioning personnel.tFig.: 47. Operation7.1 Operation with manual knobManual operation allows adjusting the control piston without electricconnection.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 end position by turning it counterclockwiseand by pushing in the circlip to its end position.On operation with manual knob, outlet "A" or “B” is connected with inputpressure "P" or with tank return line "T".The piston rod of a double-acting cylinder connected to outlet “A“ and “B”is thus uncontrolled adjusted from one end position to the other.Run piston from 0 % end position to 100% end position:•Remove locking element.•Slowly rotate manual control clockwise.•Observe cylinder. If piston moves, stop clockwise rotation•of manual knob.•Now piston moves uncontrolled to the 100 % end position.Run piston from 100 % end position to 0% end position:•From the position described above, slowly rotate manual control counterclockwise.•Observe cylinder. If piston moves, stop counterclockwise rotation of manual knob.•Now piston moves uncontrolled to the 0% end position.By reaching the end positions as described above, you may adjust orcheck e.g. a way return with electrically disconnected way valve.7.2 Operation with set signalWhen the supply system is switched on, set signal 4...20 mA may beused to position the piston rod7.3 Trouble shooting and remedial actionPrior to all work, make sure that the way valve was installed according tochapter 5 and commissioned according to chapter 6.Malfunction: Stroke variationsThe piston may show sporadic or periodical stroke variationswith different frequency and amplitude.Cause: 1. air inclusions in the control magnet VRM2. incorrectly adjusted proportional gain KP at the positioner3. impurities in the 4/3-way valveRemedy: 1. On first commissioning air inclusions in the VRM may causesporadic vibrations at the control piston, resulting in strongpressure variations at outlets "A" and “B” and thus in strokevariations at the piston. Due to periodic setpoint changes(approx. 0.5 Hz) of approx. +/- 6 mA, the air will escapefrom the VRM after some minutes causing the hydraulicdamping to become effective.2. If quick setpoint change can produce periodic vibration atthe piston, this is caused by a proportional gain adjusted toohigh. Rotate the KP potentiometer counterclockwise approx.5 times and optimize it according to chapter 6.2.3.Great alterations of the stroke adjustment or of the inputpressure require repeated optimization of the control gain.3. Contaminated pressure fluid results in increased friction atthe control piston, thus causing hysteresis and strokevariations.Open hydraulic component and clean inner elements. Incase of damaged surfaces and guiding edges replace wayvalve.Malfunction: Blowing of the upstream fuseIncorrect electric connection or operation inimpermissible ambient conditions may cause destructionof the control electronics installed in the control magnet.Remedy: Exchange the complete way valve.Repairs on the control magnet VRM are not allowed.Replace any defective way valve completely.8. Maintenance and RepairFor a trouble-free and reliable operation of the way valve, it isnecessary to perform inspection, maintenance and repair work incertain intervals.Routine inspection:Check pipes, screw connections and connections on theway valve for leakage, impurities and damage.Eliminate any leakage, impurity and damage noticed, if required, duringappropriate operating modes.Monitor the control behavior of the way valve for any changes. Analyseand eliminate the causes, if required, during appropriate operatingmodes.Instruction Manual Voith TurboWay Valve WSR-D16112Way Valve WSR-D1611804 / 06 cet - Ochs/ZAN1 Voith Turbo GmbH & Co, KG Page: 21 / 213.626 - 018901 en D – 74564 Crailsheim Inspection after approx. 740 operating hours / max. 1 month:Take an oil sample from the oil tank and analyse it for solid and suspended matters, water content, shadings and air bubbles.Analyse oil purity of the oil sample.

2.3 重要提示：应注意以下提供的说明手册及单独的附加说明。
事故预防：·由于使用不当，压力油会从密封面泄漏出来，由于周围受热的另部件而有起火的危险。
·在电液转换器投入工作前，应切断压力油。
·当电液转换器工作时，如发生电源故障或对转换器内置控制电路进行干扰，将会引起输出油压的激烈波动，油缸活塞杆的移动将会失控，造成对人身和设备的危险。
·由于压力油的关系，在运行期间，电液转换器的外表面将会升温，容易烫伤皮肤，所以在投运前应确认电液转换器已冷却。
·电器元件安装在电液转换器内部，如在其周围进行电焊，会造成这些元件的损坏。
所以，在其周进行电焊之前，必须切断电路连接。
环境保护：·在安装、拆卸、或不适当使用电液转换器时，压力油将会外漏，运行介质将会进入污水系统和外界，引起严重污染环境的危险，所以泄漏的压力油必须按有关法规进行收集和存放，妥然处理。

3.功能：3.1设计图3.1.11 - 控制磁性调节阀体P in －进口油压2 –动力传输杆P A －输出信号油压3 - ×0和×1电位计4 - 手动操作旋钮T1－回油5 - 电气接线T2 －回油6 - 控制壳体F Mag －磁力7 - 带阻尼活塞的控制活塞F Hyd－液压力8 –端盖F Fed－弹簧力9 –控制弹簧3.2 运行特性（见图3.1.1）：设定一个W=4…20mA的信号，在控制壳体内就产生一个磁力，它的大小可由电位计×0和×1来调节，电位计及其产生的磁力通过动力传输杆把力传送给控制活塞。
油压力F Hyd与输出信号油压P A相平衡，作用力与P A相反。
在两个力相等的情况下，控制活塞定位在液压中心上，如图3.1.1所示，输出信号压力P A与设定值相符。
为了保持输出油压P A处在设定值上，这个值取决于磁力F Mag，在P→P A和P A→T这个运行的边缘区越，在液压中心的位置，控制活塞达到最小振荡位移。
当从一个工况以磁力F Mag来增加设定信号，控制活塞位移，从而接通了输出油路P A和进口油路P，阻止了输出油P A通向回油管路T1和T2。
现在，输出油压将增加，直到控制活塞回到油缸中间位置，输出油压与新的设定信号相匹配。
控制弹簧的弹簧力F Fed产生一个抵消力，为了保证电液转换器能使输出油压也能达到大约0 bar的功能。
阻尼活塞提供的液压阻尼不取决于安装位置。
内部泄漏通过回油管路T2回到油箱。
手动操作旋钮的功能：通过手动操作旋钮来控制电液转换器的磁铁，依靠这个旋钮，能设定一个可调的弹簧力以替代磁力F Mag。
弹簧力通过电枢和传输杆控制活塞，液压力F Hyd与输出信号压力P A成正比，但作用力方向与弹簧力相反，这样输出压力的调节不需要电气就可实现。
