ZL50型装载机工作装置的动力来自双联齿轮泵,双联齿轮泵流量大,但在使用过程中容易出现一些故障。1.密封件失效若双联齿轮泵卸荷片的橡胶油封老化变质,失去弹性,则对高压油腔和低压油腔失去密封隔离作用,高压油腔的压力油将窜入低压油腔(称为“内漏”),使齿轮泵的工作压力和
ZL50 loader working device power from double gear pump, double gear pump flow, but prone to some faults during use. 1. Sealing Fails If the rubber seal of the double gear pump unloading sheet ages and loses its elasticity, then the high pressure oil chamber and the low pressure oil chamber will lose the sealing and isolation effect, and the pressure oil in the high pressure oil chamber will flee into the low pressure oil chamber For “Leakage ”), make the working pressure of gear pump and
