    查找液压油缸故障的诀窍

        液压油缸不能动作的重要原因是,进油口油液压力太低,即工作压力不足。造成液压系统工作压力不足的原因,主要是液压泵、驱动电机和调压阀有故障,其他原因还有:滤油器堵塞、油路通径过小、油液粘度过高或过低;油液中进入过量空气;污染严重?#36824;?#36335;接错;压力表损坏等。
        当挖掘机液压泵严重磨损对挖掘机有着致命的影响,因此挖掘机出现此类问题必须及时解决。挖掘机液压泵维修时从以下三点查找故障原因:
        1.检查动臂油缸的内漏情况
    最简单的挖掘机液压泵维修方法是把动臂升起,看其是否有明显的自由下降。若下落明显则拆卸油缸检查,密封圈如已磨损应予更换。
        2.检查操纵阀
    首先清洗安全阀,检查阀芯是否磨损,如磨损应更换。安全阀安装后若仍无变化,再检查操纵阀阀芯磨损情况,其间隙使用限度一般为0.06MM,磨损严重应更换。
        3.测量液压泵的压力
    若压力偏低,则进?#26800;?#25972;,加压力仍调不?#20808;ィ?#21017;说明液压泵严重磨损。
