1.动臂举升及收斗时速度缓慢排除此种故障的简便方法如下。若动臂缸举升无力:将装载机装满载荷, 举升到极限位置,将动臂操纵杆置于中位,并使柴油机熄火,液压泵停止供油, 观察动臂的下沉速度,然后将动臂操纵杆换置上升位置,如果这时动臂的下沉速度明显加快,则内泄原因出自动臂操纵阀。对于铲斗收斗无力现象,也可以利用类似方法,根据操纵杆在中位和后倾位置时翻斗缸的伸缩情况进行判定。此时,检查动臂缸活塞密封环是否损坏,即将动臂缸活塞缩到底,然后拆下无杆腔油管,使动臂缸有杆腔继续充油,如果无杆腔油口泄漏量大于正常值
1. Easy ways to eliminate this kind of trouble when the boom is lifted and the bucket is slow. If the boom cylinder lift ineffective: The loader is loaded, lifting to the limit position, the boom lever in the middle, and the diesel engine flameout, the hydraulic pump to stop the fuel supply, observe the boom sinking speed, Then the boom lever to the upside down position, if at this time significantly lower boom speed subsidence, the cause of the leak from the boom control valve. Bucket for the bucket weak phenomenon, you can also use a similar method, according to the joystick in the middle and backward tilt position to determine when the bucket cylinder telescopic conditions. At this point, check the boom cylinder piston ring is damaged, about to move the piston cylinder piston to the end, and then remove the rodless pipe, the boom cylinder rod cavity to continue filling, if the rodless cavity oil leakage greater than normal value
