一台厦工ZL40型装载机在施工过程中,动臂逐渐自动下沉,且随着油温的升高,下沉量越来越大。根据经验,造成该故障的原因应该在动臂缸或工作装置分配阀上。于是,启动发动机后,让装载机动臂升到最高位置,用起重机将动臂吊住并保持在最高的位置。把动臂操纵杆扳至中立位置后,将发动机熄火,然后分别拆下两个动臂缸小腔的油管放入油盆中,再启动发动机,扳动动臂操纵杆至上升位置,适当提高发动机的转速,这时我们清楚地看到左侧动臂缸小腔油管有大量油液流出,而右侧动臂缸小腔的油管几
During the construction process, a boider ZL40 loader automatically and gradually descend, and as the oil temperature rises, the sinking amount becomes larger and larger. As a rule of thumb, the cause of this failure should be on the boom cylinder or work device distribution valve. So, start the engine, let the loader boom to the highest position, with a crane to boom and hold in the highest position. The boom lever to a neutral position, the engine flame, and then remove the two small cylinder arm cylinder into the oil pan, and then start the engine, pull the boom lever to the up position, appropriately increased Engine speed, then we clearly see a small amount of oil left out of the small boom cylinder boom, and the right side of the small cylinder boom cylinder few
