液压挖掘机上的工作装置在停机后一般会自动下降,工程上称之为“液压漂移”,如果下降量太大就是故障。它一般由液压系统内泄引起,部位在液压缸和控制阀两处。但到底是哪一处,必须进一步测试后才能判断。将两处进行拆检也许能找出故障之所在,但这并不是最好的办法,现将一种简单的测试判断方法介绍如下。 Hydraulic excavator on the work of the device will normally fall automatically after the shutdown, engineering called “hydraulic drift”, if the amount of decline is a failure. It is generally caused by the hydraulic system venting, parts in the hydraulic cylinder and control valve two. But in the end is where it must be judged after further testing. Disassembling two places may be able to identify the location of the fault, but this is not the best way, now a simple test to determine the method described below.
