ZL50型装载机工作装置液压系统的常见故障有:动臂(铲斗)举升无力或动作缓慢,动臂自动下沉,液压油温过高等。现将上述常见故障排查方法分述如下:1.举升无力或动作缓慢当装载机铲斗装满物料后,若扳动动臂操纵杆动臂不能举升,即可判定为动臂举升无力。若油门最大时,动臂从最低位置上升到最高位置的时间超过14s,即可判定为动臂举升动作缓慢。排查时应先比较动臂和铲斗动作,
ZL50 loaders working unit hydraulic system of common faults are: boom (bucket) lift weak or slow motion, boom automatic sink, hydraulic oil temperature is too high. Now the above common troubleshooting methods are described below: 1 weak lifting or slow action When the loader bucket full of material, if you pull the boom lever boom can not be lifted, you can determine the boom lift Powerless. If the maximum throttle, the boom from the lowest position to the highest position of more than 14s, you can determine the boom lift action is slow. Investigation should first compare the boom and bucket action,
