通用系統(tǒng)故障排除指南以下是針對(duì)可能存在潛在困難的檢查區(qū)域的通用故障排除指南。在聯(lián)系Woodward尋求技術(shù)幫助之前，通過(guò)對(duì)您的發(fā)動(dòng)機(jī)/渦輪機(jī)進(jìn)行適當(dāng)?shù)臋z查，可以更快、更準(zhǔn)確地評(píng)估您的系統(tǒng)問(wèn)題。執(zhí)行機(jī)構(gòu)執(zhí)行機(jī)構(gòu)接線(xiàn)是否正確？筆劃的方向正確嗎？（這是使用維修工具配置的。）反饋信號(hào)是否已校準(zhǔn)？（這是通過(guò)維修工具校準(zhǔn)的。）是否設(shè)置了負(fù)載慣性？（這是使用維修工具設(shè)置的。）連桿是否有傾斜或空轉(zhuǎn)？是否存在錯(cuò)位、捆綁或側(cè)面裝載？是否有可見(jiàn)的磨損或疤痕？懸掛機(jī)構(gòu)是否平穩(wěn)移動(dòng)？閥門(mén)閥門(mén)是否平穩(wěn)地通過(guò)其適當(dāng)?shù)男谐?？閥門(mén)是否進(jìn)行全行程？可以獲得并保持中沖程嗎？調(diào)速器達(dá)到最小行程之前，閥門(mén)是否完全就位（關(guān)閉）？
· Using less than optimum actuator movement will make stability more difficult, and will make the actuator more sensitive to external loading forces and friction. Actuator exhibits “hunt” or large limit cycle. Check for loose terminal lever. Check for loose or worn linkage. Verify correct mounting hardware. Verify mounting bolts are tightened to appropriate torque values. Verify inertia setting. Unable to rotate stand alone actuator in unpowered condition Internal mechanical failure—replace actuator.
Is there misalignment, binding, or side loading? Is there visible wear or scarring? Does the linkage move smoothly? Valves Does the valve move through its proper stroke smoothly? Does the valve travel its full stroke? Can mid-stroke be obtained and held? Does the valve fully seat (close) before the governor reaches full minimum stroke? Does the valve fully open before the governor reaches maximum stroke? Mechanical Troubleshooting Guide Linkage and Actuator Stroke Use as much of the 75 degrees of actuator stroke as possible. Carefully follow the guidelines in the Driver Adjustments section of Chapter 2 in making linkage arrangements.
·General System Troubleshooting Guide The following is a general troubleshooting guide for areas to check which may present potential difficulties. By making these checks appropriate to your engine/turbine before contacting Woodward for technical assistance, your system problems can be more quickly and accurately assessed. Actuators Is the actuator wiring correct? Is the direction of the stroke correct? (This is configured using the Service Tool.) Has the feedback signal been calibrated? (This is calibrated through the Service Tool.) Had Load Inertia been set? (This is set using the Service Tool.) Linkage Is there slop or lost motion?
