The upper part is exactly what has been described in chapter 1 for module PQ0*-F00.The maximum current requirement for version PQ0*-P00 reaches up to 2.8 A, because now two proportional solenoids need to be supplied.The lower part in figure 6 shows the control of the proportional pressure pilot valve. Also for pressure setting either a voltage command (0 - 10 V) or a current command (0 - 20 mA) can be used. Also this command signal can be controlled by a potentiometer connected to the reference voltage pin 34.The pressure control circuit is equipped with an electronic network that linearizes the characteristic of the proportional pressure pilot valve (pressure over input signal). This network is dimensioned for Parker pressure valves.Figure 8: electronic module PQ0*-Q00The electronic circuit of this module is shown in figure 9. The difference to the circuit shown in figure 6 is the additional interfacefor a pressure sensor and the PID controllerfor a closed loop pressure control.As shown in figure 7, the pressure sensoris positioned in the pilot circuit. According to the differential pressure adjusted at the compensator valve, the system pressure is higher than the controlled pressure.Figure 9: electronic circuit of module PQ0*-Q00displacement.Figure 11: electronic module PQ0*-L00hydraulic circuit of a pump with ...WPR control (with shuttle valve subplate)Figure 16:shuttle valve subplate for p-Q-controlled pumps, code ...WPRsolenoid current,displacement control stagedisplacement control valve,code PVCF*PV**shuttle valve subplatepressure compensator stage, code PVCF*P2**f l o w Qpressure p 1pressuredisplacementshuttle valve insertinternal pressure port, G 1/4“ (second port opposite side)Figure 21: inductive positon transducer (LVDT), outside viewMAX-adjustment:Next the command for the displacement is to be increased, until the maximum displacement of the pump is reached.

The SCR19 Series power controllers are designed to proportion electric power to resistive loads only, such as ovens, furnaces, heat sealers, etc. The controllers consist of power semi-conductors (SCRs), properly-sized heat sinks, trigger circuitry, and fuses supplied on panels for surface mounting. (Note: They are not designed todrive transformers or any inductive load.)The power controller accepts a 4 to 20 mAdc output from atemperature controller or can be supplied with manual option using a remote potentiometer.OperationThe SCR19 Series controllers offers 2 methods of proportional control— 0-voltage-switched and phase-angled fired. With the 0 voltage switching mode, the controllerswitches on complete cycles of the AC supply voltage. The trigger circuitis designed to turn on the SCRs as close as possible to the point where the AC sine wave crosses through zero. In effect, the line voltage is turned on and off and applied to the heaters in whole cycles. With an input of 4 to 20 mA, the output will be off below 4 mA and full on at 20 mA. Proportioning action is obtained by varying the number of cycles on to the number of cycles off. The output will vary from one cycle on and9 cycles off at low input, to all cycles on at maximum input. This output is integrated by the heaters which produce a smoothly proportioning heat output that varies directly with the input signal. With the phase-angle-fired mode, the power to the load is controlled by governing the point of turn-on (firing) of each half cycle of the full AC sine wave.FeaturesU Designed to allow the operation of multiple units by a single temperature controllerU Unique circuitry in the 3-phase units allows any phaseconnection—phases cannot be incorrectly wired resulting in partial output power on or off U Optical coupler ensures theelimination of ground loops, high-voltage potentials, or damage to drive controller of the SCR power controllerU Completely solid-state, SCR19 Series SCRs have no moving parts to wear out. They are as effective as new, even after 100,000,000 operations.U SCR19 Series SCRs offer smooth, rapid, proportional heating action. SCR control proportions only the power required to maintain exact temperature.U SCR19 Series SCRs eliminate high/low cycling and, because the temperature of the heating element is constant, thermal shock is eliminated.

The point of turn on in the sine wave is at (or very near) zero voltage, thus no RFI is generated. SCR19 Series units feature an infinitely variable time base. They provide the ultimate resolution in power proportioning to the load. Also, because there are no time base adjustments to make,Phase-Angled FiredPower to load is controlled bygoverning the point of turn on (firing) of each half cycle of the full AC sine wave (see example). After triggering, the remainder of the AC cycle is applied to the load. Phase-angle-fired controllers are recommended when controlling temperatures of low-mass heating elements thatas tungsten elements, quartz lamps, hot wires and other loads requiring high inrush currents. (Note: Some RFI can be generated from thephase angle units.) A soft-start timing circuit is available that provides ramp to peak voltageto limit the power to the load atstartup. Soft start action is requiredfor loads having high current,changes the input signal from 4 to 20 mA when full output is required. It is selectable from 9, 15, 30, 60 or120 seconds. A voltage limit option is also available which “clamps” output power to a level lower thansupply power. The output power is adjustable from approximately20% to full output.ZERO VOLTAGEOMEGACARE SM extendedwarranty program is available for models shown on this page.

Basic PumpFigure 1 shows the basic construction of the PVH series piston pump. Major parts include the drive shaft, housing,yoke, rotating group, valve plate, control piston, bias piston,valve block and compensator control. The PVH seriesreplaces the pintle bearing assembly with saddle bearings,which reduces weight and eliminates the roller bearings that added to maintenance time and overhaul costs.B. Pump ControlsTwo common pump control types are available. One type is the standard “C ” compensator control that limits pump outlet pressure to a desired level. The other type is the “CV ”pressure limiter/load sensing control. Now available is the “IC ” (Industrial Control) which can be used as a load sensing compensator, remote compensator control andelectrohydraulic control. These limit pump outlet pressure and also regulate pump displacement to match load requirements.Section 3 – Principles of OperationA. Pump OperationRotation of the pump drive shaft causes the cylinder block,shoe plate and pistons to rotate (See Figure 2). The piston shoes are held against the yoke face by the shoe plate. The angle of the yoke face creates a reciprocating motion to each piston within the cylinder block. Inlet and outlet ports connect to a kidney slotted wafer plate. As the pistons move out of the cylinder block, a vacuum is created and fluid is forced into the void by atmospheric pressure. The fluid moves with the cylinder block past the intake kidney slot.The motion of the piston reverses and fluid is pushed out of the cylinder block into the outlet port.WarningBefore breaking a circuit connection, make certain that power is off and system pressure has been released. Lower all vertical cylinders, dischargeaccumulators, and block any load whose movement could generate pressure. Plug all removed units and cap all lines to prevent the entry of dirt into the system.Figure 1. PVH Section ViewFigure 2.

Pump ControlsPressure Compensator Controls “C” & “CM”(Figure 3)The standard “C” and low pressure “CM” compensator controls are internally pilot operated, spring offset, 2-way valves. Their purpose is to limit system pressure to a desired level by varying pump displacement. These controls only provide the flow required to satisfy the load demand, while maintaining a constant preset pressure.During operation, load or system pressure is continually fed to the bias piston. The function of the bias piston is to maintain the yoke at a full pump displacement position. Load or system pressure is also fed to the compensator spool chamber within the control. Pressure within the compensator spool chamber acts upon the spring force of the compensator spring.When load or system pressure is below the pressure setting of the compensator spring, the compensator spool remains offset and the pump continues to operate at full displacement. When load or system pressure approaches the compensator pressure setting, the compensator spool will start to move and overcome the compensator spring force. Fluid will then meter into the control piston area. Since the control piston area is greater than that of the bias piston,the control piston pushes the yoke towards minimum pump displacement. The compensator control continues to meter fluid to the control piston, adjusting the pump displacement, and pumping only enough fluid to satisfy the load demand while holding the system at a constant pressure.When load or system pressure exceeds the compensator setting, the compensator spool shifts towards the spring chamber area. A maximum amount of fluid is then metered to the control piston area, causing the yoke to shift to minimum pump displacement.When system pressure decreases below the compensator pressure setting, the compensator spool returns to its original position and the yoke returns to maintain maximum pump displacement.The compensator is available in two pressure ranges. The “C” spring has an adjustment range of 70–250 bar(1015–3625 psi). The “CM” spring has an adjustment range of 40–130 bar (580–1885 psi).Figure 3. “C” & “CM” ControlsI DrPBody SpringTo tankPressure limiting spoolControl pistonYoke angleBias pistonPiston pumpLoad Sensing & Pressure Compensator Control C(M)*V (Figure 4)This pump will provide power matching of pump output to system load demand, maximizing efficiency and improving load metering characteristics of any directional control valve installed between the pump and the load.Load sensing ensures that the pump always provides only the amount of flow needed by the load. At the same time, the pump operating pressure adjusts to the actual load pressure plus a pressure differential required for the control action. Typically, the differential pressure is that between the pressure inlet and service port of a proportionally controlled directional valve, or a load sensing directional control valve. When the system is not demanding power, the load sense control can operate in an energy-saving stand-by mode. To achieve the low pressure, no flow, stand-by mode, the load sense signal line must be drained to the tank externally. The standard differential pressure setting for load sense is 20 bar (290 psi), but can be adjusted to between 17 and 30 bar (247 and 435 psi) on the pump.If the load pressure exceeds the system pressure setting,the pressure compensator de-strokes the pump. The load sensing line must be as short as possible and can also be used for remote control or unloading of the pump pressure.For remote control, it is recommended that you contact your Vickers representative for the correct configuration of the control.Figure 4: C(M)*V ControlInletLoad sense signal portOutletTo load1.7 bar (25 psi)Case drainPVH with UV Control for Accumulator Circuits (Figure 5)This pump control functions as a load- sensing pressure compensator that unloads the pump at a preset pressure and loads the pump after preset pressure drop.Figure 5: UV ControlOutlet1.7 bar (25 psi)•••••Pressure & Torque Limiter Control C**T (Figure 6)This pump senses pressure and flow and starts destroking at a predetermined input torque level. The rate of flowreduction is normally tailored to follow the maximum power capability curve of the prime mover. Input torque is limited while the pressure compensator limits the system pressure.When the input speed remains constant (i.e. industrialdrives), the torque limiter acts as an input power limiter. This allows a smaller electric motor to be used if maximum pressure and maximum flow are not required at the same time. At low load levels, the control permits high pump displacement and high load speeds. Under heavy loads,speed is reduced, preventing stalling of the prime mover. In the case of variable speed drives (I.C. engines), this function provides, in addition to pressure compensation or limiting, a torque limiting ability that can be adjusted to the torque/speed characteristics of the engine.The start of torque limiting (pump-destroking) is pressure dependent. The pressure is selectable (see model code) and is factory preset to between 30% and 80% of the maximum pressure control setting. The adjustment range for the “C ”compensator is 80 to 200 bar (1160 to 2900 psi) in 10 bar (145 psi) increments. There is no “CM ” spring option available with the torque limiting control.Figure 6: C**T ControlInletCase drainOutlet To load1.7 bar (25 psi)Torque Limiting Plus Load Sensing Control C**VT (Figure 7)This pump control option functions like a load sensingcontrol, but with additional torque limiting tailored to the size of the drive motor selected. The limiting function is the same as for a pressure compensator with torque limiting. The combination of the two controls provides the following benefits:1. The energy savings of a variable displacement load sensing control.2. The pump pressure follows the load pressure.3. The torque control allows smaller drive motors to be used.4. The pressure compensator de-strokes the pump as maximum pressure is reached.5. The pump pressure can also be remotely controlled using the load sense line. The C**VT control allows complete control of flow and pressure, either mechanically or electrically, if used with proportional valves.Figure 7: C**VT ControlCase drainInletLoad sense signal portTo loadOutlet1.7 bar (25 psi)Industrial Control (Figures 8 & 9)This pump control option is intended for use when multiple,remote, or electrically controlled compensating settings, with or without load sensing, are desired.Pressure compensation is obtained by removing an internal plug, keeping the load-sense signal port plugged, and internally applying pilot pressure to the spring chamber of the pilot-operated control spool. For pressure compensation with load sensing, the internal plug stays, the load-sense signal port is unplugged, and pilot pressure is externally applied.An external relief valve is used to set system pressure. The externally adjustable control-spool spring determines the differential pressure setting of the pump control. Pilot(spring chamber) pressure is separated from outlet pressure by an internal orifice. Outlet pressure shifts the spool when pressure drop across the orifice reaches the differential pressure setting, and the pump de-strokes.The relief valve can be mounted to an NFPA-D03/ISO 4401-03 pad on the pump control, or remotely located via tapping and blanking plates installed on the pad.The standard factory-set differential pressure setting of the pump control is 20 bar (290 psi) and is not specified in the pump model code. Any other ordered differential pressure,within the control ’s adjustable pressure range of 17–35 bar (247–508 psi), will be specified in the model code following the “IC ” control code; for example, “-IC30-” for a 30 bar setting.Application examples: Mounting Control TypeD EHSTElectrical control compensator D DG valve w/DGMC Double or triple compensator D C –175Remote control relief valve D CGE –02Electrical relief valveFigure 9: Industrial ControlCase drainInletOutlet To load1.7 bar (25 psi)Tank portPressure port ••••XLoad sense signal portInletLoad sense signal portOutlet To load1.7 bar (25 psi)X Tank portPressure port ••••C. Load Sensing/Pressure Limiting OperationAs one would expect from the title, this control is acombination of the features of both the pressure limiting and load sensing controls. Refer to Figure 10.The load sensing spool senses the pressure difference (pressure drop ∆P) between pump outlet and load pressure across a series flow control or system directional valve which is inherent in its operation. This differential pressure causes the load sensing spool to move against its spring to the closed –center position. If the differential pressure (pressure drop ∆P) increases (greater flow through the series valve), the load sensing spool moves to the right.Figure 10: Load Sensing Control SystemPressure SignalSpoolSensing Compensator AdjustmentPressure Limiting SpoolTo TankFlow Control or Dir. Valve Control Piston Piston PumpBias PistonThe load sensing portion of the control operates as a function of the pressure drop across the series valves(pressure drop ∆P), and is independent of system pressure.It establishes a constant flow characteristic from the pump based on the magnitude of the directional valve opening (operator controlled).If outlet pressure increases to the maximum pressure limit setting, the pressure limiting spool meters fluid to the control piston. The control piston moves the yoke to reduce flow. If outlet pressure continues to rise, the spool will continue to meter fluid to the control piston and the pump will stroke to zero flow at maximum pressure.Reduced horsepower standby featureWhen the system flow control valve or directional valve is closed completely, the circuit is placed in standby.NoteThis feature assumes the system flow controlvalve or directional valve provides decompressionof load sensing pressure in the standby, fullyclosed position. Pressure at point A (Figures 10 &11) must decay toward zero through the systemflow control or directional valve for standby tooccur. Decompression of the load sensingpressure allows the pump to stroke to zero flowand minimum pressure. The circuit functions in thefollowing manner.Assume the flow control or directional valve is closed and there is no bleed of point A (Figure 10) to tank. The fluid is trapped and the load sensing spool is held to the left by the spring. The system pressure rises until the pressure limiting spool takes over. The yoke then stokes to zero flow and holds pressure at the maximum limiter setting.If, in the closed condition, the flow control or system directional valve bleeds point A (Figures 10 & 11) to tank, the load sensing feedback pressure will decay. The load sensing spool will shift to the left. Fluid then meters through the pressure limiting spool and into the control piston. Outlet pressure decays through pump leakage following the decay of feedback pressure A (Figures 10 & 11) until minimum pressure drop is reached. The pump will operate in the standby mode (zero flow, minimum pressure) until the flow control or system directional valve demands flow from the pump. At this time, normal operation of the controlwill resume.D. Adjustment procedure:Load Sensing PressureLimiting ControlGeneralThis procedure contains information on the PVH pressure limiting and load sensing control. Test and adjustment procedures are provided for standard units.NotePressure gauges must be installed into the systembefore adjustment of the control can be performed.Complete field test adjustment procedures areincluded.Set upMake sure all machine controls are in the OFF or neutral position.Figure 11: Gauge Connection(A) Load pressureconnection(CT/CTS control) pressure gaugeConnect a 5000 psi pressure gauge at the outlet of the piston pump and on load sensing models, in the load sensing line.Check pump housing to verify that it is full of system fluid. Jog the engine to prime the pump, then exercise the controls to eliminate entrained air in the system.Pressure Limiter AdjustmentMove an appropriate cylinder on the machine until it bottoms out. From the center condition, crack the control valve lever toward the bottomed out position enough to allow pressure build up in the system. DO NOT exceed the maximum pressure limit noted in Table 1. If the maximum pressure limit does not correspond to Table 1, adjustment of the control is required.CautionDO NOT adjust control while machine is running. Adjust the pressure limit set screw (clockwise to increase, counterclockwise to decrease) until the pressure noted in Table 3 is obtained.PumpModelTable 1.

The difference between pump pressure and load pressure is the load sense pressure drop. To increase the load sensing pressure drop (∆P), rotate load sensing adjusting screw clockwise. To decrease the setting, rotate the load sensing adjusting screw counterclockwise. The standard factory setting is 290 psi ∆. If this pressure drop is set too low, system instability can occur. Correct this by increasing pressure drop.E. Overhaul of PVH Controls Disassembly of C, CM Control (Refer to Figure 12)CautionDO NOT disassemble or remove control whileengine is running.

May also be referred to as “suction lift”. The atmospheric pressure of 14.7 psi at sea level limits suction head lift to less than approximately 26 feet for any pump.Discharge Head is the vertical distance between the pump’s discharge port and the point of discharge, which is the liquid surface if the hose is submerged or pumping into the bottom of a tank.Total Head is the sum of the suction head value plus the discharge head value.As water pumping height increases, pump output decreases. The length, type, and size of the suction and discharge hoses can also significantly affect pump output. It is important for the suction operation to be the shorter part of the total pumping action. This will decrease the priming time and improve pump performance by increasing the discharge head.Suction head is a maximum of 25 feet and discharge head should be a maximum of 81 feet. Total head can not be more than 106 feet as shown on next page.Move Water Pump to Safe Operating Location For best pump performance, locate the pump on a flat, level surface as close as possible to the water to be pumped. Secure water pump to avoid tipover. Use hoses that are no longer than necessary.IMPORTANT: Direct open end of discharge hose away from home, electrical devices or anything not desired to get wet.operation15Prime the Water Pump 1.

OMEGA PV100 电子控制比例阀说明书
PV100 SERIES ELECTRONICALLY CONTROLLEDPROPORTIONAL VALVESUnpackingRemove the Packing List and verify that you havereceived all equipment, including a PV100 Seriesproportional valve, and instruction sheet. If youhave any questions about the shipment, please callthe Customer Service Department at 1-800-622-2378or 203-359-1660. We can also be reached on theInternet at e-mail:******************When you receive the shipment, inspect thecontainer and equipment for signs of damage. Noteany evidence of rough handling in transit.Immediately report any damage to the shippingagent.General DescriptionThe OMEGA®PV100 Series ElectronicallyControlled Proportional Valves are two-waynormally closed valves. When the valve isdeenergized, pressure is sealed off by the force ofthe plunger assembly return spring and the seal inthe plunger assembly. When the valve is energized,the plunger assembly moves upward, permittingflow through the valve. The valve is direct acting.Higher current or control signal results in moreplunger movement and more flow.InstallationPort IdentificationApply inlet pressure to the port marked “P”.Mounting Position and Pressure Limits Valves can be mounted directly on piping and aredesigned to operate in any position. Two 8-32tapped mounting holes 1⁄4” deep are provided in thebase of the body. Line pressure must not exceed thenameplate rating.PipingRemove closures from ports and connect pressurelines to proper ports. All valves have 1⁄8" NPTFfittings. Tightening torque on the 1⁄8" NPT shouldnot exceed 38 in-lbs.Media FiltrationFiltration of air lines is recommended. Install thefilter in the inlet side as close to the valve aspossible. These valves have no sliding fits and aregenerally not sensitive to a small amount of foreign material, however, they do contain soft rubberinserts. Dirt or foreign material in the media maycause excessive leakage, excessive wear, or inexceptional cases, malfunction.Electrical ConnectionElectrical supply must conform to nameplaterating. Connect coil leads to DC voltage usingstandard electrical practice.Black wire Common Ground(to Power Supply and Control) Red wire(+) DC Positive Power SupplyGray wire(+) Control SignalIf the coil housing is located in an inconvenientposition, the housing nut can be loosened and thehousing rotated to any convenient position. Thenre-tighten the nut to 13 to 35 in-lbs.Coil Housing TemperatureStandard valves are supplied with coils designedfor continuous duty service.

Fill housing with hydraulic fluid and start the pump in the test stand.2. Increase the pressure with the restrictor valve on the return line. Max allowed pressure is 150 bar / 2150 psi.3. Check the drain flow and compare with the table.För funktionskontroll behövs en provbänk med kapacitet 30l/min och 300 bar. Ett sekundärflöde på 3-5 l/min och tryck 25 bar krävs för ställdon med extern matning.EP ställdon kräver en förstärkare.Test1. Fyll V12 med olja ihuset och starta pumpen i testbänken.2.

第一个“*”表示泵的规格：A 代表PV016 - PV046 C 代表PV063 - PV092 E代表PV140 - PV270末尾两个“**”表示密封件材料与螺钉选项 (详见备件表PVI-PVC -UK)。
液压回路图，…FPV 控制采用该型控制器的泵上安装有一个电感式位置传感器(LVDT)，用以检测变量伺服活塞的位置，并向电子控制器提供实际的排量反馈信号。
变量活塞有杆腔端的环形面积上作用有泵的出口压力p 1，该压力与变量伺服弹簧一起推动活塞向泵最大排量方向运动，而排量控制阀的输出压力则作用在活塞无杆腔端的较大面积上，将推动活塞向排量减小的方向运动。
排量控制阀阀芯的一端装有偏置弹簧，另一端则承受比例电磁铁的推力，当有指令信号输入时，比例电磁铁推力将克服弹簧在标称电流(1.3 A)下，比例电磁铁的推力将能克服偏置弹簧力，推动控制阀芯移动至将控制口A 与泵壳体泄油(油口L)连通的位置，变量活塞的无杆腔端经控制阀芯卸荷，变量活塞在有杆腔端的泵出口压力p 1和变量伺服弹簧的作用下，移动至泵全排量位置，全排量的数值由排量调节螺钉限定。
比例电磁铁无电流输入时，控制阀芯在复位弹簧的作用下移动至其初始阀位，即：控制油A 与压力口p 1相通的位置，将泵出口压力引入变量伺服活塞的无杆腔端，该端的活塞受力面积大大排量控制阀 代号：PVCF*PV**排量控制阀电磁铁电流 排量反馈信号 排量压力 p 1流量 Q力推动阀芯移动，使之进入控制位置，此时，阀芯在压力口p1与控制口A之间形成一定的控制开度，此开度与控制口A和泄油口L之间的节流口D B一起构成一个所谓的半桥压力分配回路，该压力分配回路控制A口的压力p A。
按照变量活塞两端的面积比，在变量的过程中，控制压力p A大约是泵出口压力p1的25%。
地大于有杆腔的环形受压面积，故在泵出口压力p1的作用下，变量活塞克服变量伺服弹簧力，将斜盘推至泵最小排量位置。
此工况下，要求的泵出口压力p1至少为15 bar。
如果不能保持该压力值，则要求针对具体的排量控制，采取相应的专门措施。
没有适当的负载压力，泵将始终处于全排量状态。
Parker 可提供专门的电子控制模块，用于对…FPV 型比例排量控制器的控制，该电子控制模块的订货代号为：PQ0*-F00，其中“*”为一位数字，表示PV 系列轴向柱塞泵5种壳体规格中的一种。
PQ0*-F00 电子控制模块该型电子控制模块按卡扣式导轨安装设计，符合EN 50011。
该型模块要求的供电电源为：22-36 VDC ，电气接线见第20页的接线图，连接至LVDT(排量反馈)及排量控制阀的比例电磁铁，要求的电流约为1.4 A 。
排量的输入指令可由0-10V 的电压信号或0-20mA 的电流信号给定，模块本身可提供经过稳压和滤波处理的10V 参考电压，利用此参考电压，结合使用电位器(最小10kO)，可生成电压输入指令。
该指令信号在模块内部与LVDT 给出的实际排量反馈信号进行比较，生成一个误差信号，并由该误差信号控制排量控制阀电磁铁的电流。
只要排量未到达要求的数值，就存在误差信号，电磁铁电流就增大，使控制压力降低，变量活塞动作，从而使泵的排量增大，直至达到要求的数值为止。
模块带有诊断输出，能用以监测泵的实际排量。
该诊断输出为0至约10V 的电压信号，表示0~100%的泵排量 (有关某一壳体规格的实际最大排量，详见26页的技术参数表)。
该模块提供有对增益的调节，以使控制回路的设定与液压系统的动态响应相匹配。
该模块同时提供有斜波功能，能对上升和下降的斜波分别进行调整。
利用MAX 调整，可按要求的排量范围优化输入信号的分辨率。
MIN 电位器用于调节最小排量，在输入信号超过100 mV 时进行调节。
代号…FPV 的比例排量控制不包含压力补偿变量功能，液压回路中必须设置全流量的溢流阀予以保护，以避免液压系统中的压力过高。

压力补偿变量功能由与排量控制阀组合配置的第二套控制器 (遥控型压力补偿控制器) 来实现。
下图所示为此类排量控制器的液压回路，该示意图中，采用电磁比例压力先导阀来控制遥控型压力控制级 (代号为…FPD/… UPD 的控制器包含有该比例压力阀)，可通过电气输入指令，连续地调节压力补偿变量控制器的设定值。
压力补偿变量控制器的控制阀芯的位置，由跨越在先导节流口D p 上的压力降和补偿器偏置弹簧力来控制，标称的控制压差由工厂设定为12±1 bar 。
只要泵的出口压力还没有达到压力先导阀 (见第5页的液压回路：电磁比例压力先导阀 PVACPP**) 的压力设定值，补偿器 偏置弹簧将压力补偿变量控制器的控制阀芯保持在图示的初始位置上，压力补偿控制功能不起作用。
而排量控制阀的控制油口A 与变量伺服活塞的无杆腔相连接，故此时变量伺服活塞的位置由排量控制阀进行控制。
排量控制器的工作状况如同第1节所述，控制压力的调整在控制阀芯的开口和控制节流口D B1之间实现。
当泵的出口压力达到压力先导阀的设定压力时，该先导阀开启，于是形成一个压力分配控制回路，控制流量从泵出口压力p 1起始，流经控制节流口D p 和压力先导阀开口，返回到泵的壳体泄油，并在控制节流口Dp 上产生压力降，如果该压力降达到压力补偿器的12 bar 控制压差设定值，则压力补偿变量控制级的控制阀芯就将处在它的控制位置状态，使泵的排量减小，从而保持泵的出口压力恒定。

此时，压力补偿变量控制器的工作状况与使用标准的遥控型压力补偿变量控制器相同。
必须满足的条件是，排量控制级的排量设定值应足够大，应能覆盖系统的流量要求，如此，泵和控制阀才能保持所需的工作压力。
PQ0*-P00 电子控制模块此型电子控制模块除了具有第一节中阐述的PQ0*-F00型模块所具有的比例排量控制的功能以外，还提供对PVACPP35*比例压力先导阀进行控制的功能。
右页所示为该型电子控制模块的电气回路图，图中的上面部分正是第一节中阐述的模块PQ0*-F00的电路图。
由于有两个比例电磁铁需要供电，故PQ0*-P00型模块要求的最大电流达2.8A。
电气回路图中的下面部分所示为比例压力先导阀的控制回路，压力设定指令同样可使用电压信号 (0-10V) 或电流信号 (0-20 mA)，同样地，该指令信号也可以通过连接在参考电压接线脚34上的电位器来控制。
该压力控制回路配置有电子网络，用于对比例压力先导阀的特性(输出压力与输入信号的对应关系)进行线性化处理，该数据处理网络是针对 Parker 压力阀量身定制的。
因此，该型电子控制模块仅适用于对下列阀件的控制：PVACPP35* ( *为密封件材料选项代号)如果用于控制其它类型的阀件，则会导致控制不稳定或发生故障。
该型比例压力先导阀的标称压力为350 bar，利用电子控制模注：出于以下三个原因，Parker 决定采用这种对比例排量控制实施越权监控的单独的遥控型液动操控压力补偿控制器。
1. PV系列柱塞泵具有一个较大的变量伺服活塞，这自然提供了一些优点，但另一方面，这个大伺服活塞也要求提供较大的流量来实施补偿变量，液动操控的压力补偿器(如本型控制器所使用的) 能提供比其它类型的泵控制模块所使用的比例方向控制阀要大得多的控制流量。
比例方向阀也可用于压力补偿变量控制，它是基于压力传感器提供的信号进行压力补偿控制的。
2. 由于系统压力直接作用在控制阀芯上，液动操控的压力补偿器“感受”系统中的压力峰值，按照实际的系统压力，可以获得很大的作用力来操纵阀芯，因此，这种控制机构绝少有卡死现象或发生故障，而比例方向控制阀在油液污染的情况下就经常会出现这类卡死现象或故障。
