The Load SharingModule allows use of Woodward power generation accessories and allows loadsharing between engines equipped with speed controls that are not manufacturedby Woodward and engines controlled with Woodward electronic controls, orcontrols using other Woodward load sharing modules.DescriptionThe Load Sharing Module provides isochronous and droop load-sharingcapability for engines in generator set applications. Additional equipment in thecontrol system can include the Woodward SPM-A Synchronizer, Import/ExportControl, Automatic Generator Loading Control, and Automatic Power Transferand Loading Control.Figure 1-1 shows a typical system using a Load Sharing Module.Figure 1-1.

Plant Wiring Diagram of Load Sharing ModuleWoodward 5Load Sharing Module Manual 020356 WoodwardChapter 2Electrostatic Discharge AwarenessAll electronic equipment is static-sensitive, some components more than others. To protect these components from static damage, you must take special precautions to minimize or eliminate electrostatic discharges.!CAUTIONTo prevent possible serious damage to the Load Sharing Module, do not attempt to service the unit beyond that described in the operating instructions. All other servicing should be referred to qualified service personnel.Follow these precautions when working with or near the Load Sharing Module.1. Before doing maintenance on the Load Sharing Module, discharge the staticelectricity on your body to ground by touching and holding a groundedmetal object (pipes, cabinets, equipment, etc.).2. Avoid the build-up of static electricity on your body by not wearingclothing made of synthetic materials. Wear cotton or cotton-blend materials as much as possible because these do not store static electric charges asmuch as synthetics.3. Keep plastic, vinyl, and styrofoam materials (such as plastic or styrofoamcups, cup holders, cigarette packages, cellophane wrappers, vinyl books or folders, plastic bottles, and plastic ash trays) away from the Load SharingModule, the modules, and the work area as much as possible.4. Do not remove the printed circuit board (PCB) from the electronic cabinetunless absolutely necessary, and then only after all input power has beenremoved from the unit. If you must remove the PCB from the electroniccabinet, follow these precautions:•Do not touch any part of the PCB except the edges.•Do not touch the electrical conductors, the connectors, or thecomponents with conductive devices or with your hands.•When replacing a PCB, keep the new PCB in the plastic antistatic protective bag it comes in until you are ready to install it. Immediatelyafter removing the old PCB from the electronic cabinet, place it in theantistatic protective bag.Chapter 3InstallationIntroductionThis section contains general installation instructions for the Load Sharing Module. Environmental precautions and location considerations are included to determine the best location for the Load Sharing Module. Additional information includes unpacking instructions, electrical connections, and an installation check-out procedure.UnpackingBefore handling the Load Sharing Module, read Chapter 2, Electrostatic Discharge Awareness. Be careful when unpacking the Load Sharing Module. Check the unit for signs of damage such as bent or dented panels, scratches, and loose or broken parts. Notify the shipper of any damage.Location ConsiderationsConsider these requirements when selecting the mounting location:• Adequate ventilation for cooling• Space for servicing and repair• Protection from direct exposure to water or to a condensation-prone environment• Protection from high-voltage or high-current devices, or devices which produce electromagnetic interference• Protection from excessive vibration• An ambient operating temperature range of –40 to +70 °C (–40 to +158 °F) Do not mount the Load Sharing Module on the engine.Figure 1-2 is an outline drawing of the Load Sharing Module. Install the unit as close as practical to the electronic engine control, but not on the engine itself. It may be installed in any position.To maintain compliance with CE marking requirements, the European Union Low Voltage Directive requires that the Load Sharing Module (LSM) be mounted in an IP43 enclosure as defined in EN60529. Access to the Load Sharing Module must be restricted to qualified personnel.General Wiring RequirementsThe circled ground symbol identifies the Protective Earth Terminal.This terminal must be connected directly to protective earth using agrounding conductor at least as large as those used on terminals 1through 9. The insulation of the grounding conductor must be ofgreen and yellow color.This symbol identifies functional or EMC earth. This terminal is tobe used for cable shield connections only. It is not to be used as aprotective earth terminal.External wiring connections and shielding requirements for a typical installation are shown in the plant wiring diagram, Figure 1-4. These wiring connections and shielding requirements are explained in more detail in this chapter.To maintain compliance with CE marking requirements, the Low Voltage Directive requires that the Load Sharing Module must only be connected to Class III equipment.Wiring for the Load Sharing Module must be suitable for at least 90 °C (194 °F) and also be suitable for the maximum installed operating temperature.The Load Sharing Module must be permanently connected and employ fuses or circuit breakers in each of the PT lines to limit current to the LSM PT inputs to no more than 5 A. In addition, a 2 A fast-acting fuse or circuit breaker must be provided in the 24 Vdc power supply line.All terminal block screws must be tightened to 0.56 to 0.79 N·m (5.0 to 7.0 lb-in).To maintain compliance with CE marking requirements, the EMC Directive requires that all shields be connected to the terminals provided per the plant wiring diagram, Figure 1-4.Power RequirementsThe Load Sharing Module is powered from a 24 Vdc source. The 24 Vdc source must be a minimum of 18 Vdc and a maximum of 32 Vdc continuous. If a battery is used for operating power, an alternator or other battery charging device is necessary to maintain a stable supply voltage.!CAUTIONTo prevent possible serious damage to the Load Sharing Module, make sure the alternator or other battery charging device is turned off or disconnected before disconnecting the battery from the unit.Shielded WiringAll shielded cable must be twisted conductors with either a foil or braided shield. Do not attempt to tin (put solder on) the braided shield. All signal lines should be shielded to prevent picking up stray signals from adjacent equipment. Connect the shields to the terminals indicated in the plant wiring diagram. Wire exposed beyond the shield must be as short as possible.The other end of the shields must be left open and insulated from any other conductor. Do not run shielded signal wires with other wires carrying large currents. See Application Note 50532, EMI Control for Electronic Governing Systems, for more information.Where shielded cable is required, cut the cable to the desired length and prepare the cable as instructed below and shown in Figure 3-1.Figure 3-1. Preparation of Shielded Cables1. Strip outer insulation from both ends, exposing the braided or spiral wrappedshield. Do not cut the shield on the end nearest to the Load Sharing Module.Cut off the shield on the end away from the unit.2. Use a sharp, pointed tool to carefully spread the strands of the shield.3. Pull the inner conductors out of the shield. Twist braided shields to preventfraying.4. Connect lugs to the shield and to the control wires. Number 6 slotted orround crimp-on terminals are used for most installations. Connect the wires to the appropriate terminals on the module.Installations with severe electromagnetic interference (EMI) may require shielded wire run in conduit, double shielded wire, or other precautions.Generator ConnectionsNOTEUse 1 mm² (18 AWG) or larger wire for all PT and CT connections.The spacing between the lugs on terminals 3 and 4 must be 6.5 mm(0.256 inch) or greater to comply with the European Union LowVoltage Directive (see Figure 1-4). The lugs must have insulatedsleeves.IMPORTANTConnections from the potential transformers and currenttransformers must be made correctly in regard to the three phasesfor the Load Sharing Module to operate correctly. Sorting out thethree phases at the module is tedious and requires numerousgenerator starts and stops. If at all possible, make sure that thewiring is correctly done at the time of installation and the phasescorrectly and permanently identified at the generator and at themodule.Connect the PT output from the A leg to terminal 1. Connect the PT output fromthe B leg to terminal 2. Connect the PT output from the C leg to terminal 3. Sizethe potential transformers to produce 100–240 Vac.Current TransformersPower source current transformers should be sized to produce 5 A secondarycurrent with maximum generator current (3–7 A secondary current at full load isacceptable). CT burden is 0.1 VA. To prevent lethal high voltage fromdeveloping on leads to the terminals, the Load Sharing Module contains internalburden which must be connected across the power source current transformerswhenever the unit is running. Ammeters may be installed on the leads from thecurrent transformers.Connect phase “A” CT to terminals 4 and 5. Connect phase “B” CT to terminals6 and 7. Connect Phase “C” CT to terminals 8 and 9. Observe correct phasing asshown in the plant wiring diagram, Figure 1-4.Load Sharing Lines, Droop, and Auxiliary ContactsThe droop contact for selecting droop or isochronous operation is wired in serieswith the circuit breaker auxiliary contact between terminals 13 and 14. Whenboth the droop contact and circuit breaker auxiliary contact are closed, the LoadSharing Module is in the isochronous load sharing mode. In this mode theinternal load-sharing-line relay is energized, the droop signal is disabled, and theload matching circuit is connected to the load-sharing lines, permittingisochronous load sharing.The Load Sharing Module is in the droop mode when EITHER the droop contact or the circuit breaker auxiliary contact is open. If the droop contact is open, the Load Sharing Module remains in the droop mode even when the circuit breaker auxiliary contact is closed. If droop is not desired when the auxiliary contact is open, turn the droop potentiometer fully counterclockwise.Use a single pole, single-throw switch with a 0.1 A minimum rating for the “open for droop” switch.Output to the Engine Speed ControlUse twisted 0.5 mm² (20 AWG) or larger shielded wire to connect the 0.5–4.5 Vdc output signal from terminals 19 (+/signal output), 20 (common), and 21 (optional, external 5 Vdc reference) to the control. Connect the shield to the closest chassis screw only. Do not connect the shield at the speed control end of the wiring.Synchronization ConnectionsIf an SPM-A synchronizer is used, connect twisted-pair 0.5 mm² (20 AWG) or larger shielded wire from the synchronizer to terminals 24(+) and 25(–). Tie the shield to the closest chassis screw. Do not connect the shield at the synchronizer end of the wiring.Speed Trim PotentiometerIf a speed-trim potentiometer is used, connect a 10 k 10-turn potentiometer to terminals 26 (CW), 27 (wiper), and 28 (CCW). Use 0.5 mm² (20 AWG) or larger shielded wire, and connect the shield to the closest chassis screw. Do not connect the potentiometer end of the shield.The potentiometer is used to move the speed setting when manually synchronizing the generator or to change load demand in droop mode.External 5 Vdc Reference (Optional)An external +5 Vdc reference voltage may be connected between terminal 21(+) and chassis ground (–). The reference voltage determines the zero bias output level, 0.50 x Vref, and the minimum and maximum output range, 0.1 x Vref and 0.9 x Vref. Connection to an external reference will automatically override the LSM internal 5 volt reference.When using a DDEC III or IV control, terminal 916 could be connected to terminal 21. Terminal 916 is a 5 Vdc reference from the DDEC control that is referenced to terminal 952 that is connected to terminal 20 of the LSM.Chapter 4Setup and CalibrationIntroductionUse this calibration procedure after a Load Sharing Module is installed on a generator set, to obtain the needed operating characteristics during load sharing.1. Check the input power on terminals 15(+) to 16(–) for 24 Vdc. Properpolarity must be maintained.2. Remove wires from load sharing line terminals 10 and 11, and from theSPM-A Synchronizer (if used) at terminals 24 and 25.3. Select isochronous operation by shorting terminals 13 and 14.4. If a speed setting potentiometer is used, set it to mid position (50%).!WARNINGTO PROTECT AGAINST POSSIBLE PERSONAL INJURY, LOSS OF LIFE, and/or PROPERTY DAMAGE EACH TIME you START the engine, turbine, or other type of prime mover, BE PREPARED TO MAKE AN EMERGENCY SHUTDOWN to protect against runaway or overspeed should the mechanical-hydraulic governor(s), or electric control(s), the actuator(s), fuel control(s), the driving mechanism(s), thelinkage(s), or the control devices fail.5. Start the engine according to the engine manufacturer’s instructions. Adjustthe engine for rated speed. Apply full load to the generator set.NOTEThe most accurate calibration is made at full load. However, if it isnot possible to run the generator set at full load, run it at less thanfull load, and reduce the voltage readings given in this calibrationprocedure proportionally. For example: run a 200 kW generator set at100 kW and divide all voltages given in this calibration procedure by2. If you reduce the load in this manner, be sure to reduce it by thesame amount throughout the calibration procedure.6. Set the LOAD GAIN potentiometer fully clockwise.7. Check the load signal voltage between terminals 22 and 23. Adjust theLOAD GAIN potentiometer for 6.0 Vdc signal. If this voltage is notobtainable, set the load signal as close as possible to 6 Vdc.8. Remove the load from the generator set.9. Check the voltage between terminals 22 and 23. This voltage should be 0.0± 0.25 Vdc. If this voltage is not correct, the Load Sharing Module is faulty or there may still be load on the generator.Phasing Check!WARNINGA high voltage across open CTs (current transformers) can cause death or serious injury. Do not disconnect a CT from the Load Sharing Module while the engine is running. The CTs can develop dangerously high voltages and may explode if open circuited while the engine is running.For this check, the generator set must be running isochronously, not paralleled, and with a power factor greater than 0.8.10. Check that the potential connections are made as follows and correct themif they are not.• Phase A to terminal 1• Phase B to Terminal 2• Phase C to Terminal 3NOTEThe most accurate calibration is made at full load. However, if it isnot possible to run the generator set at full load, run it at less thanfull load, and reduce the voltage readings given in this calibrationprocedure proportionally. For example: run a 200 kW generator set at100 kW and divide all voltages given in this calibration procedure by2. If you reduce the load in this manner, be sure to reduce it the sameamount throughout this calibration procedure.11. Start the engine and apply full load to the generator set.12. Using a dc voltmeter, measure the load signal at terminals 22 and 23. Adjustthe load gain potentiometer to give a 6 Vdc load signal. If 6 Vdc is notobtainable, set the load signal as close as possible to 6 Vdc. Record thisvoltage.13. Shut down the generator set.!WARNINGA high voltage across open CTs (current transformers) can cause death or serious injury. Do not disconnect a CT from the Load Sharing Module while the engine is running. The CTs can develop dangerously high voltages and may explode if open circuited while the engine is running.14. Disconnect the wire from terminal 5 that comes from the phase “A” CT andconnect both wires from this CT to terminal 4.15. Start the generator set and apply full load.16. Measure the load signal at terminals 22 and 23. If the phase “B” and “C”current transformers are connected correctly, this voltage will be 1/3 lower than the voltage recorded in step 13. For example: if the reading was 6 volts in step 13, the reading in this step should be approximately 4 volts.17. Shut down the generator set.18. Reconnect the phase “A” CT wire to terminal 5.19. If the reading in step 16 was correct, proceed to Load Gain Adjustment laterin this chapter. Otherwise, perform the following Phase CorrectionProcedure.Phase Correction ProcedureIf this procedure is followed, the correct connection of the current transformers is assured; the correct CT will be connected to the correct input on the Load Sharing Module with the correct polarity. Use this procedure only if the Phasing Check indicates that the phasing is incorrect.A CT for any phase (A, B, or C), will produce the most positive load signal voltage when it is connected, in the proper polarity, to the terminals on the Load Sharing Module which correspond to the same phase. Any other connections of this CT will produce a less positive load signal voltage. This procedure makes trial connections of the first CT to all three CT inputs on the Load Sharing Module, polarized both ways on each CT input. The load signal voltage is recorded for each connection, and the CT is then connected to the CT input terminals that produced the most positive load signal voltage and with the polarity that produced the most positive load signal voltage.In a like manner, the second CT is tried on each of the two remaining CT input terminals in each polarity, then connected, in the correct polarity, to the terminals which produced the most positive load signal voltage.The remaining CT is then connected to the remaining CT input and the load signal checked for each polarity. This CT is then connected to the CT input, polarized so that it produces the most positive load signal voltage.When the procedure is completed, all three CTs are connected to the proper CT inputs on the Load Sharing Module, with the correct polarity, and are now labeled with their correct designations.The procedure for correcting phase wiring requires that the generator set be shut down and the current transformers disconnected many times. For convenience during the phasing check, the temporary method of connecting the current transformers shown in Figure 4-1 is recommended. By connecting a burden resistor (a 0.5 , 20 W resistor), across each current transformer, that current transformer can be disconnected from the Load Sharing Module after removing all load. The connections between the terminal strip and the Load Sharing Module can be changed with the generator set running; however, remove all load before any changes in connections are made. Do not disconnect a wire from a current transformer with load on the system. After completion of the procedure remove the terminal strip and the resistors.Figure 4-1. Temporary CT Connections!WARNINGA high voltage across open CTs (current transformers) can cause death or serious injury. Do not disconnect a CT from the Load Sharing Module while the engine is running. The CTs can develop dangerously high voltages and may explode if open circuited while the engine is running.For this procedure, the generator set must be running isochronously, not paralleled, and with a power factor greater than 0.8.1. Start with the generator shut down.2. Label each CT wire with the phase and polarity that you think it should be.Even though this identification may prove to be wrong during thisprocedure, this step is necessary so that the individual wires may beidentified during the description of the procedure.3. Disconnect the phase “B” CT wires from terminals 6 and 7 and connectthese two wires together. Use a small screw and nut and tape theconnection.4. Disconnect the phase “C” CT wires from terminals 8 and 9 and connectthese two wires together. Use a small screw and nut and tape theconnection.5. Connect the two wires from the phase “A” CT to phase “A” input terminals4 and 5.!WARNINGTO PROTECT AGAINST POSSIBLE PERSONAL INJURY, LOSS OF LIFE, and/or PROPERTY DAMAGE EACH TIME you START the engine, turbine, or other type of prime mover, BE PREPARED TO MAKE AN EMERGENCY SHUTDOWN to protect against runaway or overspeed should the mechanical-hydraulic governor(s), or electric control(s), the actuator(s), fuel control(s), the driving mechanism(s), thelinkage(s), or the control devices fail.6. Start the engine and apply full load.7. Measure the load signal voltage between terminals 22 and 23 and recordthis voltage.8. Shut the generator set down and reverse the phase “A” wires on terminals 4and 5.9. Start the engine and apply full load.10. Measure the load signal voltage between terminals 22 and 23 and recordthis voltage.11. Shut the generator set down.12. Remove the phase “A” CT wires from terminal 4 and 5 and connect thephase “A” CT wires to the phase “B” input terminals 6 and 7.13. Start the engine and apply full load.14.

4–20 mA/1–5 Vdc Speed SetSpecial circuits provide high- and low-limit adjustments. These limits set the maximum and minimum speed that can be set by varying the speed-setting milliamp or voltage reference. The low limit can be set as high as rated speed, if desired, limiting the ability of the process or computer speed setting to reduce speed. If needed, the low-limit setting can be used to control engine operation on loss of the speed-reference signal.The start-fuel limit sets a maximum actuator position during the start sequence. It is biased out of the way when speed reaches the control set point. This feature can be used to limit excessive startup smoke, reduce cylinder wear caused by the washing action of excessive fuel, and help reduce startup time. An external switch connection is provided to disable the start-fuel limit, if desired, to prevent reverse-acting systems from reverting to the start-fuel position on loss of magnetic pickup.All 2301A controls feature an internal, isolated power supply for improved noise immunity and ground-loop protection. The control provides maximum protection from electromagnetic and radio-frequency interference.Outline Drawing of Remote Speed Reference 2301ASPECIFICATIONSSpeed Range An internal switch selects one of the following speed ranges:500 to 1500 Hz1000 to 3000 Hz2000 to 6000 Hz4000 to 12000 HzSpeed Sensing 1 to 30 Vac. Input Impedance is 1 k( at 1 kHz Externally Applied Speed Reference Proportional to 4–20 mA or 1–5 Vdc input. Speed reference isproportional to applicable input signal.SPM-A Synchronizer Input–5 t +5 Vdc for –3.3% to +3.3% or –1.5 to +1.5 Vdc for –1% to 1%speed change. Impedance is 100 k(.Minimum Fuel Opening the external minimum fuel switch will send a minimum-fuelsignal to the actuator. The minimum-fuel switch is an optionalmeans for a normal shutdown. Not to be used for emergencyshutdown.Droop Where droop is required, an external potentiometer is used to setthe desired percentage of droop. Use a 2 k( potentiometer for up to7.5% droop when 2/3 actuator travel is used for 0–100% load. Leavedroop potentiometer terminals open if only isochronous operation isdesired.Failed Speed Signal Override Close the external contact to override the failed speed protectivecircuit when required for start-up.Weight About 1.1 kg (2.5 pounds). May vary slightly depending on model. POWER SUPPLYHigh Voltage Model90 to 150 Vdc or 88 to 132 VacLow Voltage Model20 to 40 VdcADJUSTMENTSStart Fuel Limit Sets actuator current between 25% and 100% of specifiedmaximum actuator current during start-up. Actuate the Start FuelLimit Override when placing a reverse acting system on line.Level Sets speed set point demanded by minimum control signal input.Range Sets speed reference demanded by maximum control signal input.Low Limit Sets minimum speed reference that can be demanded by controlsignal.

• Slip frequency paralleling, voltage matching, and speed bias transfer between the synchronizer andload control result in smooth paralleling without therisk of reverse power trips• Three-phase true RMS power sensing makes the DSLC control accurate even with unbalanced phaseloading and voltage fluctuations• Can load share with Woodward analog controls when used with the Load Sharing Interface Module (8239-082). Refer to Woodward Manual # 02031 for details. OPERATING MODESIsolated Bus—The DSLC control talks over its LON to share proportional real and reactive loads. Real load (kW) is controlled using percentages of full load for each machine, and reactive loads (kVAR) are shared by matching power factors. The DSLC control maintains a specified bus voltage and frequency while balancing loads. Utility Parallel—TheDSLC control measuresreal load (kW) on thegenerator and adjusts thespeed control to match aset base load, or tocontrol a process at auser-chosen, externallyadjustable set-point. Itcan be set to a constantimport/export level usingan MSLC ( MasterSynchronizer and LoadControl). The DSLCcontrol can also measureand maintain a setreactive load (kVAR) orcan maintain a user-prescribed power factor.Transition BetweenModes—The DSLCcontrol will ramp at auser-chosen rate fromone mode to another untilthe control is within 5% ofits target. It then shiftsinto dynamic control,allowing bumplessoperating mode changes.In addition, the DSLCcontrol automaticallychanges its VAR/PFmode when the real loadmode is changed to orfrom an isolated load sharing application. Manual VAR/PF control may also be selected.ADJUSTMENTSThe Woodward Hand Held Programmer makes all adjustments quickly and easily, through the control’s ten convenient “menus”. The control saves all set points in permanent memory, which does not require batteries or other power sources to retain data. The Hand Held Programmer prevents tampering with set points, yet allows entries to be changed at any time. The Hand Held Programmer displays in plain English, so there are no codes to look up or memorize.Menu 1–Synchronizer FunctionsMenu 2–Load Control FunctionsMenu 3–Process Control FunctionsMenu 4–VAR/Power Factor Control FunctionsMenu 5–ConfigurationMenu 6–CalibrationMenu 7–Generator Electric ParametersMenu 8–Control Status MonitorMenu 9–Discrete Inputs/Outputs MonitorMenu 0–DiagnosticsTypical Wiring Connections(120/240 V wye switchgear configuration)SPECIFICATIONSEnvironmental SpecificationsOperating Temperature.....................................................–40 to +70 °C (–40 to +158 °F)Storage Temperature........................................................–55 to +105 °C (–67 to +221 °F) Humidity...............................................................................95% at 38 °CElectromagnetic Susceptibility.........................................ANSI/IEEE C37.90.2; ANSI C37.90.1-1989Mechanical MIL-STD 810C, Method 516.2, Procedures I, II, V MIL-STD 167, Type IElectrical SpecificationsControl Power Supply Input Operating.............................................................................8–32 Vdc continuous (as low as 10 Vdc, 1.8 A max, or as high as 77 Vdc for upto 5 min) Reverse................................................................................–56 Vdc continuous Burden..................................................................................18 W, 1 A max.Voltage Sensing Inputs120 Vac Input (L-N) Wye PT Configuration....................65–150 Vac, terminals 4–5, 7–12, 9–12, and 11–12240 Vac Input (L-N) Wye PT Configuration....................150–300 Vac, terminals 3–5, 6–12, 8–12, and 10–12120 Vac Open Delta PT Configuration...........................65–150 Vac, terminals 3–5, 6–8, 8–10 and 10–6240 Vac Open Delta PT Configuration...........................150–300 Vac, terminals 3–5, 6–8, 8–10, and 10–6 Phases.................................................................................Three phase generator bus, single phase parallel bus Frequency............................................................................45–66 Hz Burden..................................................................................Less than 0.1 VA per phase Accuracy...............................................................................0.1% of full scaleCurrent Transformer Inputs (CTs) Current..................................................................................0–5 Arms, 7 Arms max.

WOODWARD飞机调速器构造原理及调试方法孙一【摘要】针对WOODWARD 210776\"C系列\"调速器的研究,该类调速器主要安装于TB系列飞机,对调速器构造及工作原理进行深入分析,并详细介绍了调试方法,可以帮助一线维修人员减少维修工时,提高效率,也有助于提高飞行教员和学员对飞机调速器的理论认识.【期刊名称】《技术与市场》【年(卷),期】2019(026)008【总页数】2页(P126-127)【关键词】调速器;调试【作者】孙一【作者单位】中国民用航空飞行学院飞机修理厂,四川德阳618300【正文语种】中文0 引言WOODWARD公司成立于美国，从电子机械和液压运动控制器制造商逐渐发展成为具有130多年发动机控制器设计和制造经验的大公司，在先进的飞行控制系统、集成式驾驶舱控制器、精确执行机构、运动控制和传感方面树立了航空和防御工业的全球标杆。

其产品种类主要有电磁阀、调速器、调节控制系统、电控液压放大器、执行器、电流压力转换器等，广泛应用于航空、工业发动机及发电控制。

WOODWARD公司所制造的调速器型号众多如210776、210761、210681、210681等，本文主要针对WOODWARD 210776“C系列”调速器进行研究。

210776 C调速器主要安装于TB系列飞机，其作用是对螺旋桨变距滑油压力的控制，以实现变距角度的控制，不断地调整螺旋桨的角度使螺旋桨在一定范围内，都保持适中的迎角，使得螺旋桨具有较高的工作效率和发动机保持稳定的工作状态。

1 WOODWARD飞机调速器基本构成WOODWARD飞机调速器由头部组件、壳体组件、基座组件组成。

头部组件包括顶盖、操纵摇臂组件、调速弹簧、柱塞组件。

操作摇臂组件通过外置的控制摇臂可实现人工变距，为了提高工作效率，飞行员操纵变距杆(即转速调节控制摇臂)来压缩或放松调速弹簧，即改变调速弹簧力，这样与之平衡的飞重离心力就需要改变，从而实现发动机转速的改变。
