在工程机械液压系统故障判断和修理中,如何迅速检查和判断液压缸是否有内泄漏?一般人们都是采用传统的方法;把液压缸内活塞拆出来,检查活塞上的油封有无损坏。但此方法费工费时,下面介绍一种快速简便的方法。 当怀疑液压缸某作用方向有内泄漏时,可先把液压缸内活塞动作至该方向的极限位置,停机后拆下该作用方向的液压缸回油管,用 In construction machinery hydraulic system fault diagnosis and repair, how to quickly check and determine whether there is hydraulic cylinder leakage? The general people are using the traditional method; the hydraulic cylinder piston removed, check the piston seal without damage. However, this method takes time and labor, the following describes a quick and easy way. When it is suspected that there is an internal leakage in the direction of action of the hydraulic cylinder, the piston in the hydraulic cylinder may be actuated to the limit position in the direction. After stopping, the hydraulic cylinder return pipe in the acting direction is removed,
