How is the air cooler maintained?

Dirt removal: chemical method, that is, according to the characteristics of scale is generally alkaline, use dilute hydrochloric acid to dissolve scale. But the acid content should not be too high, otherwise it will corrode the metal. Specific cleaning method: first make dilute hydrochloric acid solution, add 5~10KG hydrochloric acid to 100kg of water, dilute hydrochloric acid tank is placed in the lower part of the cooler, the bottom is connected to a leather pipe to a small water pump, the water pump and the cleaned air cooler channel form a circuit circulation. After the water pump is started, it is circulating and cleaned with dilute hydrochloric acid solution, which is generally cleaned for about 6 hours. If it is winter cleaning, the solution can be heated to 70~80 degrees to increase the cleaning speed and increase the cleaning effect. After washing the dilute hydrochloric acid solution, drain the liquid and rinse with clean water. In order to avoid acid corrosion, a 5% soda solution can be used to circulate for 10 minutes, and then rinse with clean water.
