R3000H Load Haul Dump Caterpillar


Cooling System Coolant Sample (Level 1) - Obtain

Usage:

R3000H RCM
注: 如果冷却系统中加注的是 Cat ELC(长效冷却液),则无需获取冷却液液样(1 级)。 加注 Cat ELC 的冷却系统应进行冷却液取样(2 级)。 遵循保养周期表中规定的间隔。

注: 如果冷却系统加注了任何其他类型冷却液,而不是 Cat ELC 的话,应获取冷却液液样(1 级)。 以下类型的冷却液需要取样。

  • 符合 Caterpillar 发动机冷却液技术规格 -1(Caterpillar "EC−1")的市售长效冷却液

  • Cat 柴油发动机防冻剂/冷却液(DEAC)

  • 市售重负荷冷却液/防冻剂


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: 1 级分析的结果可能表明需要进行 2 级分析。

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史记录,应按均匀间隔进行一致的取样。 从 Caterpillar 代理商处获得采样所需的器具。

请遵循下列指南,对冷却液进行正确的取样:

  • 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。

提交样本进行 1 级分析。
