除一个良好的预防性保养程序以外,Caterpillar 建议按计划周期定期使用 S·O·S 机油分析,以监控发动机状况和发动机的保养要求。

采样与分析

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

热油和热的部件可能会导致人员受伤。 不要让热的油和部件接触皮肤。


采样之前,填好标签, PEEP5031 以便识别样品。 为了有助于获得最精确的分析结果,提供下列信息:

  • 发动机型号

  • 发动机的工作时数

  • 机油的使用小时数

  • 上次更换机油以来的机油添加量

为了确保油样能代表曲轴箱中的机油,要获取热的、充分混合的机油油样。

为了避免机油油样的污染,用来获取机油油样的工具和容器必须清洁。

机油采样阀

Caterpillar 建议使用取样阀来获取机油油样。 通过采样阀抽取的油样,具有较好的质量,并且比较稳定。 取样阀的位置使得油样能在发动机正常运转时压力下流出。

用采样阀采样时,建议使用 8T-9190 油液采样瓶总成。 油液采样瓶总成包括采样机油油样所需的零件。 同时还提供了说明。


注意

必须分别使用专用的机油采样泵和冷却液采样泵。 使用同一个泵去进行两种液体的采样会污染抽取的液样。 这种污染可能会导致代理商和客户关注由此造成错误的分析和不正确的解释。


如果发动机上未装取样阀,就使用 1U-5718 真空泵。 该泵设计成可安装取样瓶。 必须使用一次性的管子接到泵上,并插入油底壳中。

有关说明请参阅专门出版物, PEHP6001, "如何获取良好的油样"。 为了获得完整资料和协助制订您发动机的机油定期油样分析程序(S·O·S),请与 Cat 代理商联系。
