Cooling System Water Temperature Regulator - Replace

Usage:

CW-16 N6J
定期更换水温调节器,以降低非计划停车误工及冷却系统出故障的机率。

在冷却系统清洗完毕之后,再更换水温调节器。 彻底排空冷却系统后,更换水温调节器。 将冷却系统冷却液排放至低于水温调节器壳体的液位后,更换水温调节器。


注意

不能定期有计划地更换水温调节器会引起发动机严重损坏。


注: 如果只是要更换水温调节器,将冷却系统冷却液排放至低于水温调节器壳体的液位。

  1. 打开发动机室。

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

    在工作温度下,发动机冷却液是热的,并且带有压力。

    蒸汽还会引起人身伤害。

    只有在发动机已关闭且加注口盖冷却到可徒手触摸后,才能检查冷却液液位。

    缓慢卸下加注口盖,释放其中压力。

    冷却系统添加剂含碱。 应避免皮肤和眼睛与其接触,以防造成人身伤害。


  2. 拆下冷却系统压力盖,以便释放冷却系统压力。

  3. 松开软管卡箍 (3),从水温调节器壳体 (1) 上拆下软管 (4)。

  4. 卸下水温调节器壳体 (1) 的螺栓 (2),然后卸下水温调节器壳体 (1)。

  5. 从水温调节器壳体上拆下密封垫和水温调节器。 记下旧调节器的方位。


    注意

    如果水温调节器在测试的技术规格内,没有损坏、没有过量的沉积物,水温调节器可以再用。



    注意

    由于卡特彼勒发动机采用了分流式设计的冷却系统,所以要求必须有水温调节器才可以运转发动机。

    否则由于负载不同可能导致过热或过冷的情况。



    注意

    水温调节器 如果安装不正确,则会造成发动机过热。


  6. 安装新的水温调节器。 使水温调节器与旧调节器处于同样的方位。 安装新密封垫。 安装水温调节器壳体。

  7. 安装水温调节器壳体和软管。 拧紧软管卡箍。

  8. 向冷却系统加注冷却液。 使分路水箱上冷却液的液位保持在最低线与最高线之间。

  9. 检查冷却系统压力盖和垫片有无损坏。 如果压力盖或垫片损坏,更换压力盖。

  10. 安装冷却系统压力盖。

  11. 关闭发动机室。
