在水温调节器失效之前将其换掉。 这是推荐的预防性保养经验。 更换水温调节器可减少可能发生的计划外停工。 请参阅操作和保养手册, "保养周期表"了解正确的保养时间间隔。

水温调节器在部分开启位置失效时,会引起发动机过热或过冷。

水温调节器在完全关闭位置失效时,会引起发动机严重过热。 发动机严重过热会引起气缸盖开裂或活塞卡缸故障。

水温调节器在开启位置失效时,会引起发动机在部分负荷运行时工作温度过低。 发动机部分负荷时工作温度过低会造成缸内过分积碳。 从而加速活塞环和缸套的磨损。


注意

不定期更换水温调节器会引起发动机严重损坏。

卡特彼勒发动机的冷却系统包括有分流设计,此种设计要求在安装了水温调节器的情况下运行发动机。

如果水温调节器安装不正确,发动机可能过热,造成气缸盖损坏。 确保新的水温调节器安装在原来的位置。 确保水温调节器的放气孔畅通。

不要在密封垫或缸盖表面上使用液体垫片材料。


请参阅拆卸和安装手册, "“水温调节器 - 拆卸”和“水温调节器 - 安装”"来了解水温调节器的更换程序,或者咨询您的Caterpillar代理商。

注: 如果只更换水温调节器,排放冷却系统中的冷却液时,冷却液的液位只需低于水温调节器壳即可。
