液压泵故障的成因及查找故障的方法

18-04-21 10:33

一、根据液压系统配件图查找液压故障在液压系统图分析排除故障时,主要方法是“抓两头”——即抓动液压泵配件和执行元件(柱塞缸体),然后是“连中间”,即从动力源到执行元件之间经过的管路和控制元件。“抓两头”时,要分析故障是否就出在油泵、缸体和电动机本身。“连中间”时除了要注意分析故障是否出在所连线路上液压元件外,还要特别注意弄清楚系统从一个工作状态转移到另一个工作状态时是采用哪种控制方式,控制信号是否有误,要针对实物,逐一检查,要注意各个主油路之间及主油路与控制油路之间有无接错而产生相互干涉现象,如有相互干涉现象,要分析是何等使用调节错误等。
