机床液压设备常见故障分析及维修实例

Fault analysis and maintenance embodiment of hydraulic apparatus in the lathe

机床液压系统一般较难直接判断出产生故障的主要原因。因此,分析液压系统故障,根据故障现象进行判断,逐步深入分析,采用跟踪追击的分析方法,有目的、有方向地逐步缩小范围。笔者分析了液压系统故障的特征,通过长期实践总结了一套新的故障诊断方法。

Generally, it is difficult to determine the main causes of faults in the hydraulic system of the lathe directly. So, the analysis of faults in the hydraulic system, the determination according to trouble phenomenon, and the in - depth analysis should be made progressively, then with the analytical method, the questionable points could be decreased purposefully. In this paper, the characteristics of hydraulic system faults is analyzed, and a new set of fault diagnosis methods is summerized.
