柱塞式喷油泵常见故障原因与诊断

Common Fault Causes and Diagnosis of Plunger Type Fuel Injection Pump

喷油泵根据柴油机的不同工况,定时、定量、定压地将柴油输送到喷油器,再由喷油器将柴油雾化喷入气缸,在高温和高压作用下着火燃烧做功的核心部件。若喷油泵出现故障,将影响柴油机正常工作,本文主要介绍柱塞式喷油泵常见故障原因及其诊断方法,供柴油机使用维修人员参考。

Fuel injection pump according to different conditions of diesel engine, timing, quantitative, fixedpressure will be delivered to the fuel injector of diesel, and then by the atomization of diesel injector will be injectedinto the cylinder, in the high temperature and high pressure under the action of the fire burning for power. Fuel in-jection pump failure, will affect the normal operation of diesel engine, this paper mainly introduces the commonfaults and treatment method of plunger type fuel injection pump, In order to diesel engine use and repair personnelreference.
