编辑手语对液压系统的故障诊断方法基本相同，一般是先分析，后测试,最后拆卸故障的可疑部位。我处在承建某地下工程中，一台配有Cop1038HD凿岩机的H169二臂凿岩台车，在换件修理后试机时出现以下故障现象：（1）左右臂开机工作半小时后，油温过高（超过gOt），液压系统的冲击? Edit sign language on the hydraulic system fault diagnosis method is basically the same, usually first analysis, after testing, and finally dismantle the suspicious parts of the fault. I was in the construction of an underground project, with a Cop1038HD rock drill H169 two arm rock drill, replacement parts in the repair after the test machine when the following symptoms: (1) left and right arm boot half an hour later, the oil temperature Too high (over gOt), hydraulic system impact?
