注: 热交换器的保养间隔将根据工况和环境变化而变化。 应按以下间隔评估保养间隔:

  • 按本操作和保养手册, "保养间隔周期表"中说明的间隔

  • 在发动机操作的第一 1000 小时之后

  • 每 2 年至少一次

循环流经热交换器的 原/海水 和船只操作时间的长短影响到下列各项:

  • 热交换器片的清洁程度

  • 热交换系统的效率

在含有 泥沙 、沉积物、盐、 藻类 或其它值得注意的杂质将会对热交换系统产生不良影响。 此外,间歇性使用船只也会对热交换系统产生不利影响。

下述各项指示热交换器可能需要清洁:

  • 冷却液温度升高

  • 发动机过热

  • 进水口和出水口之间的压力下降过大

熟悉冷却液正常工作温度的操作员可以确定冷却液温度在何时超出了正常工作范围。 如果发动机过热,就需要对热交换器进行检查和保养。

有关热交换器的保养和清洁的资料,请参阅拆解与组装, "热交换器 - 拆解"。
