东风_4型机车的起动机油泵,由于工作时间短,因而故障少,处理故障的经验也就少。我段的由资阳内燃机车工厂新造的东风_4型3016号机车,于1985年12月10日,柴油机起动后起动机油泵没有停止运转,并且手柄提到16位时,机油压力只有167kPa(1.7kgf/cm~2),出现了一起不常见的故障。柴油机起动时,起动机油泵是由起动机油泵电机QD驱动的,而电机QD是由蓄电池通过主触头QC供电的。所以柴油机起动后该泵不停转,人们往往认为是由于主触头QC失 Dongfeng _4 locomotive starter pump, due to short working hours, so fewer failures, less experience in troubleshooting. I paragraph by the Ziyang diesel locomotive factory new Dongfeng _4 type 3016 locomotive, on December 10, 1985, the diesel engine start after the start pump does not stop, and the handle referred to 16, the oil pressure is only 167kPa (1.7 kgf / cm ~ 2), there has been an unusual breakdown. The diesel engine starts, the starter pump is driven by the starter pump motor QD, and the motor QD is supplied by the battery via the main contactor QC. Therefore, the pump does not stop the pump after starting the rotation, people often think it is due to the main contact QC loss
