    挖掘机伸缩臂动作慢的原因

    挖掘机冷车干活正常,热车动作慢,一般情况下是挖掘机内部元件由于时间时间厂产生的磨损(挖掘机缸体、柱塞、配流盘、九?#35013;濉?#40863;?#36710;?#30952;损),从而导致挖掘机发动机功率下降与液压系统内泄.

    另外,如果此时挖掘机使用的时间不长,那导致出现挖掘机动作慢?#25910;?#29616;象原因就有可能是:挖掘机电路保险丝短路、先导压力不正常、伺服控?#21697;?伺服活塞卡死、分配器合流等.

    还有:
    转速传感器坏了或者是传感器?#27844;收?
    发动机功率下降,可以做一下油门校正.
    挖掘机的液压油长时间没换.
    挖掘机的流量没达到要求等
