一台ZL50型装载机在使用中常出现动臂缸和转斗缸运动速度缓慢的现象,该机的工作装置液压系统的检查和调整方法如下:1.液压缸运动速度发动机怠速运转,动臂杆处于下降位置,空载铲斗从最高位置下降到地面的时间不应大于5.5s;铲斗装有额定载荷并降到最低位置,发动机和液压油处于正常的工作温度时,加大油门使发动机以额定转速运转,操纵分配阀的动臂阀杆,使动臂升到最高位置所需时间不应大于8s;在动臂提升的条件下,铲斗从最大后倾位置翻转到最大前倾位置,所需时间不应大于3s。
A ZL50 loader in the use of boom cylinder and bucket cylinder often appear slow movement phenomenon, the working unit hydraulic system inspection and adjustment methods are as follows: 1. Cylinder speed of the engine idling, boom lever In the down position, no-load bucket from the highest position down to the ground time should not exceed 5.5s; Buckets with rated load and down to the lowest position, the engine and hydraulic oil at normal operating temperature, increase the throttle so that the engine Operating at rated speed, manipulating the boom valve stem of the distribution valve so that the time required for the boom to rise to the highest position should not be greater than 8 seconds; with the boom raised, the bucket is flipped from the maximum recline position to the maximum forward tilt position , The time required should not exceed 3s.
