產(chǎn)品概述：
連桿必須在沒(méi)有摩擦和齒隙的情況下自由移動(dòng)。某些燃油控制裝置在特定的燃油或齒條位置會(huì)出現(xiàn)問(wèn)題，原因是連桿中存在猶豫或卡滯。燃油供應(yīng)和噴油器狀況也可能出現(xiàn)類似調(diào)速器問(wèn)題的問(wèn)題。在火花點(diǎn)火發(fā)動(dòng)機(jī)上，分配器、線圈、點(diǎn)和正時(shí)問(wèn)題都可能導(dǎo)致操作不當(dāng)，這可能類似于調(diào)速器控制故障。使用錯(cuò)誤的電壓可能會(huì)損壞控制裝置。更換控制裝置時(shí)，檢查電源、電池等電壓是否正確。故障排除步驟本章是隔離系統(tǒng)問(wèn)題的通用指南。本指南假定系統(tǒng)接線、焊接連接、開(kāi)關(guān)和繼電器觸點(diǎn)以及輸入和輸出連接正確且處于良好工作狀態(tài)。按照指示的順序進(jìn)行檢查。各種系統(tǒng)檢查都假定先前的檢查已正確完成。
引言發(fā)動(dòng)機(jī)操作不當(dāng)通常是調(diào)速器操作以外的因素造成的。本章提供了有關(guān)發(fā)動(dòng)機(jī)問(wèn)題的提示，這些問(wèn)題可能類似于調(diào)速器問(wèn)題。在對(duì)調(diào)速器進(jìn)行任何更改之前，請(qǐng)確保發(fā)動(dòng)機(jī)工作正常。以下故障排除指南有助于隔離控制箱、執(zhí)行器、接線或其他地方的故障。只有當(dāng)有完整的控制測(cè)試設(shè)施可用時(shí)，才建議進(jìn)行超過(guò)該級(jí)別的故障排除。試圖通過(guò)調(diào)速器調(diào)整不及時(shí)來(lái)糾正發(fā)動(dòng)機(jī)或負(fù)載問(wèn)題可能會(huì)使問(wèn)題變得更糟。如果可能，將調(diào)速器與發(fā)動(dòng)機(jī)隔離，以確定問(wèn)題是否出在調(diào)速器上，而不是發(fā)動(dòng)機(jī)或發(fā)動(dòng)機(jī)負(fù)載上。調(diào)速器故障通常是由執(zhí)行器和發(fā)動(dòng)機(jī)之間的安裝或連桿問(wèn)題引起的。在對(duì)執(zhí)行機(jī)構(gòu)或驅(qū)動(dòng)器進(jìn)行任何調(diào)整之前，請(qǐng)仔細(xì)檢查所有接線、電源和連桿。始終像執(zhí)行器在移動(dòng)燃油控制連桿一樣，從一個(gè)止點(diǎn)到另一個(gè)止動(dòng)點(diǎn)檢查燃油控制連桿。
Fuel supply and injector conditions can also present problems, which resemble governor problems. On spark-ignited engines, distributor, coil, points, and timing problems can all cause improper operations, which may resemble faulty governor control. The control can be damaged with the wrong voltage. When replacing a control, check the power supply, battery, etc., for the correct voltage. Troubleshooting Procedure This chapter is a general guide for isolating system problems. The guide assumes that the system wiring, soldering connections, switch and relay contacts, and input and output connections are correct and in good working order. Make the checks in the order indicated. Various system checks assume that the prior checks have been properly done.
If possible, isolate the governor from the engine to determine if the problem is with the governor and not with the engine or the load on the engine. Governor faults are usually caused by problems in the installation or the linkage between the actuator and the engine. Carefully review all the wiring connections, the power supply, and the linkage before making any adjustments to the actuator or driver. Always check the fuelcontrol linkage from stop to stop as if the actuator were moving it. The linkage must move freely without friction and without backlash. Some fuel controls will present problems at particular fuel or rack positions because of a hesitation or binding in the linkage.
Introduction Improper engine operation is often the result of factors other than governor operation. This chapter gives tips about engine problems, which can resemble governor problems. Make sure the engine is operating correctly before making any changes in the governor. The following troubleshooting guide is an aid in isolating trouble to the control box, actuator, wiring, or elsewhere. Troubleshooting beyond this level is recommended ONLY when a complete facility for control testing is available. Attempting to correct engine or load problems with untimely governor adjustment can make problems worse.
