Hydraulic Oil Contamination - Test

Usage:

AP-1000E DKH

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

滚热的油或液压油的压力会对人员造成伤害。

发动机停机之后,液压油的压力仍会保留在液压系统里。 对液压系统进行维修之前,如果不事先释放压力,可能会造成严重伤害。

确保所有的选装部件已降下,并确保在拆卸任何部件和管路前油冷却下来。 只能在发动机停机,并且加注口盖冷却到可以用徒手触摸时才能卸下加注口盖。



注意

机器做检查、保养、测试、调整和修理时,必须小心,不让液体流出。 在打开任何腔室或拆解任何储有液体的部件之前,要准备好用合适的容器收集液体。

有关可提供予卡特彼勒机器的工具及适合于盛装液体的容器,请参阅技术手册, NENG2500, "卡特彼勒工具及车间用品指南"。

按照本地法规和指令处置所有液体。


如果油受到污染,可能会造成部件的早期故障。 受到污染的油也会引起过热。

按照以下程序确定液压系统中机油的污染程度。

  1. 从 S·O·S 口 (1) 获取液压油油样。

    注: 有关正确步骤,请参阅操作和保养手册, KEBU7026, "液压系统油样 -获取"。

  1. 检查液压滤清器滤芯中有无异物。

    1. 青铜色颗粒说明泵或马达配流盘发生故障。

    1. 闪亮的钢颗粒说明泵故障或马达活塞发生故障。

    1. 橡胶颗粒物说明密封或软管发生故障。

    1. 铝颗粒说明进料充油泵、风扇驱动马达、排风扇马达或夯实驱动马达中发生故障。

注: 如果在液压滤清器滤芯中发现这些颗粒物中的任意一种,则必须清洁液压油系统的所有部件。 不要使用任何损坏的零件。 必须拆下损坏的零件并安装新零件。
