Visual Inspection

Usage:

572R II DSC
液压系统和相应部件的目视检查是识别故障的第一步。

进行以下检查。

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

如果检查渗漏的方法不当,会造成人身伤害甚至死亡。

检查渗漏时,请务必使用木板或硬纸板作为挡板。 即使只是针孔大小的渗漏,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。


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

必须使动臂在整个行程进行提升和下降以测试液压系统。

为了避免人身伤害,应该在具有足够的动臂间隙的区域执行此项测试,尤其是要远离电源线和工作人员。 施加停车制动以防止机器移动。


  1. 检查所有机具油路连接是否有损坏或泄漏。

  2. 检查从机具连接至阀连接的所有机油管路。 检查管路和连接有无损坏或泄漏。

  3. 检查泵和接头有无损坏和泄漏。

  4. 跟踪至油箱和阀的泵管路。 检查管路和油箱有无损坏或泄漏。

  5. 检查油箱里的油位。

  6. 使用清洁的瓶子或容器,以便在机器停止后立即获得油样。 检查油样中有无气泡。

  7. 拆下滤芯,并检查滤清器是否有从油中过滤到颗粒。 可使用磁铁将铁质材料从滤清器中的非铁质颗粒中分离出来。
