柴油发电机的散热器如何维修保养 How to repair and maintain the radiator of a diesel generator

柴油发电机的散热器维修保养周期为每运行200小时进行一次:

外部清洁:

用热水(加入清洁剂)喷洗，方法是从散热器前面向风扇方向喷射(如从反方向喷射只会把污物逼进中心位置)，使用此方法时，要用胶布挡住柴油发电机;

如果上述方法不能清除顽固的沉积物，则应把散热器拆下浸在热的确良碱水中约20分钟，然后用热水清洗。

内部除垢:

把水从发电机散热器中排干，然后把散热器与管子相连的地方拆开封口;

向散热器中倒入45c的4%的酸溶液,过15分钟后排干酸溶液，检查散热器;

如果仍有水污，则用8%的酸溶液再清洗一次;

除垢后用3%的碱溶液中和两次，然后再用清水冲洗三次以上;

所有工作完成后，检查散热器是否漏水，如果漏水则申请外委修补;

如果不漏水则重新装回，散热器装回后应重新灌满清水并加入防锈剂。

The maintenance cycle for the radiator of the diesel generator is once every 200 hours of operation:

External cleaning:

Spray hot water (with cleaning agent) towards the fan from the front of the radiator (spraying in the opposite direction will only push the dirt into the center). When using this method, use adhesive tape to block the diesel generator;

If the above method cannot remove stubborn deposits, the radiator should be removed and immersed in hot caustic soda water for about 20 minutes, and then cleaned with hot water.

Internal descaling:

Drain the water from the generator radiator and then open the seal where the radiator is connected to the pipe;

Pour 45c of 4% acid solution into the radiator, drain the acid solution after 15 minutes, and check the radiator;

If there is still water pollution, clean again with an 8% acid solution;

After descaling, neutralize twice with a 3% alkaline solution, and then rinse three or more times with clean water;

After all work is completed, check if the radiator is leaking water. If it is leaking, apply for outsourcing repair;

If there is no water leakage, it should be reinstalled. After reinstalling the radiator, it should be refilled with clean water and rust inhibitor should be added.
