液压系统是工程机械中的一个重要部分,一般来说,液压系统的工作是可靠的,但在使用过程中,由于维护不好或设计不合理等原因,也会出现一些故障。由于液压系统都是密封的,故发生故障时不易查找原因,一般从现象入手,分析可能的原因并个检查。只要找到故障,故障就不难排除。一方面决 Hydraulic system is an important part of construction machinery, hydraulic system in general is reliable, but in the course of use, due to poor maintenance or design and other reasons, there will be some failure. Because the hydraulic system is sealed, it is not easy to find the cause of the failure, the general phenomenon from the start, analyze the possible causes and a check. Just find the fault, the fault is not difficult to rule out. On the one hand decision
