LAM 810-099175-009 电源组件
产品概述：
连杆必须在没有摩擦和齿隙的情况下自由移动。某些燃油控制装置在特定的燃油或齿条位置会出现问题，原因是连杆中存在犹豫或卡滞。燃油供应和喷油器状况也可能出现类似调速器问题的问题。在火花点火发动机上，分配器、线圈、点和正时问题都可能导致操作不当，这可能类似于调速器控制故障。使用错误的电压可能会损坏控制装置。更换控制装置时，检查电源、电池等电压是否正确。故障排除步骤本章是隔离系统问题的通用指南。本指南假定系统接线、焊接连接、开关和继电器触点以及输入和输出连接正确且处于良好工作状态。按照指示的顺序进行检查。各种系统检查都假定先前的检查已正确完成。
引言发动机操作不当通常是调速器操作以外的因素造成的。本章提供了有关发动机问题的提示，这些问题可能类似于调速器问题。在对调速器进行任何更改之前，请确保发动机工作正常。以下故障排除指南有助于隔离控制箱、执行器、接线或其他地方的故障。只有当有完整的控制测试设施可用时，才建议进行超过该级别的故障排除。试图通过调速器调整不及时来纠正发动机或负载问题可能会使问题变得更糟。如果可能，将调速器与发动机隔离，以确定问题是否出在调速器上，而不是发动机或发动机负载上。调速器故障通常是由执行器和发动机之间的安装或连杆问题引起的。在对执行机构或驱动器进行任何调整之前，请仔细检查所有接线、电源和连杆。始终像执行器在移动燃油控制连杆一样，从一个止点到另一个止动点检查燃油控制连杆。
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.
