------ WARNING! ------

检查渗漏时,请务必使用木板或硬纸板作为挡板。 即使是从针孔大小的渗漏中漏出的空气或液体,都能够穿透人体组织而造成严重创伤,甚至死亡。 如果液体喷射穿透进您的皮肤,必须立即找熟悉这类型创伤的医生处置。


找寻问题时,目测液压系统,转向系统和其它不同部件。 将机具下降到地面后停运发动机。 作以下检查:

  1. 跟踪所有液压机具的管路,从机具的连接点到阀的连接点。 检查以下部件有否损坏,也检查以下部件有否漏损。

    • 所有的液压机具管路。

    • 所有部件的连接点。

  1. 检查控制阀有否漏损。

  1. 检查以下部件有否损坏,也检查以下部件有否漏损。

    • 机具和转向泵

    • 部件的连接点

  1. 跟踪从机具和转向泵到液压油箱的管路。 同时,跟踪从机具和转向泵到各阀门的管路。 检查以下部件有否损坏,也检查以下部件有否漏损。

    • 从机具和转向泵到液压油箱的管路

    • 从机具和转向泵到各阀门的管路

    • 液压油箱

    • 部件的连接点

  1. 检查液压油箱的油位。

  1. 关于油品取样的信息,请参阅您机器的操作和保养手册。
