摘　　要：液压挖掘机被广泛应用于煤矿、建筑、水利等各机械化施工中。但是由于挖掘机的工况复杂,在工作中经常会出现各种故障,其中液压故障最为常见,并且检修难度大,为了缩短故障诊断及排除时间,本文针对几种常见的液压系统故障,从液压系统的结构及工作原理方面进行了分析,介绍了故障的诊断及排除方法。Hydraulic excavators are widely used in mechanized construction of coal mines,construction,and water conservancy.However,due to the complex working conditions of the excavator,various failures often occur in the work.Hydraulic failures are the most common and are difficult to repair.In order to shorten the fault diagnosis and eliminate the time,this article analyzes several common hydraulic system failures from the hydraulic system structure and working principle,and introduces the fault diagnosis and troubleshooting methods.
