测试发动机冷却液对于确保发动机不受内部气穴侵蚀和腐蚀非常重要。 该分析还会测试冷却液防止发动机沸腾和结冻的能力。 S·O·S 冷却液分析可在您的 Cat 代理商处进行。 Cat S·O·S 冷却液分析是监测冷却液和冷却系统的最佳方法。 S·O·S 冷却液分析是一个基于定期采样的计划。

有关冷却液分析和其他冷却液的更多信息,请参考操作和保养手册, "油液建议"。


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。



注意

在检查、保养、测试、调整及维修产品时,请小心确保盛接油液。 在打开任何舱室或拆卸任何含有油液的部件前,请准备好盛接液体用的适当容器。

有关适于收集和盛放 Cat 产品油液的工具和用品,请参阅专门出版物, NENG2500, "Cat 代理商维修工具目录"或专门出版物, PECJ0003, "Cat 车间用品和工具目录"。

按照本地法规和要求处置所有油液。


  • 开始采样前,填写采样瓶标贴上的事项。

  • 将未用过的取样瓶保存在塑料袋中。

  • 从冷却液取样口直接获得冷却液液样。 不要从其它地方取样。

  • 直到开始取样时,再取下空取样瓶的瓶盖。

  • 为防止杂质污染,取样后应立即将样品装入邮寄管中。

  • 切勿从膨胀瓶中取样。

  • 切勿从系统的排放口取样。

注: 每次换油时或每隔 250 小时检查传统冷却液的 SCA(补充用冷却液添加剂)。 在首个周期执行该检查。

尽可能接近推荐的取样间隔期进行冷却液的取样。 为获得最佳的 S·O·S 分析效果,必须建立前后一致的数据趋势。 为了建立相关的数据历程,应按均匀间隔进行前后一致地取样。 从 Cat 代理商处提供所需的用品。

交上进行 1 级分析用的样品。

注: 1 级分析的结果可能表明需要进行 2 级分析。
