How to remove the scale in the air compressor cooler
We use a kettle to boil water. After the kettle is used for a long time, a layer of scale formed by bicarbonate substances such as calcium and magnesium in the water will grow on its inner wall. This situation will also occur after the air compressor cooler is used for a long time. We generally clean the scale of the kettle, and the scale of the air compressor cooler should also be cleaned in time. Because the scale will affect the normal heat transfer of the air compressor cooler, the air compressor inlet and exhaust temperature will increase, and the air can not be cooled to the predetermined temperature, which directly affects the production cost and even the safe operation. Therefore, according to the specific situation should work out a regular cleaning scale plan is necessary.
We can learn from daily life that there are two ways to clean scale, physical removal and chemical methods, which are as effective as cleaning the scale of the air compressor cooler.
Physical elimination method:
The physical method uses a wire brush or a wire cloth strip to drag the tube back and forth to eliminate the scale in the tube.
Chemical method:
The chemical method is to dissolve the scale with dilute hydrochloric acid according to the characteristics of the scale is generally alkaline. But the acid content should not be too high, otherwise it will corrode the metal. The specific cleaning method is: first make dilute hydrochloric acid solution, add 5-10KG hydrochloric acid to 100KG water, dilute hydrochloric acid tank is placed at the bottom of the cooler, and the bottom is connected with a leather tube to the small pump, and the pump and the cleaning cooler channel form a loop cycle. After the pump is started, the water is cleaned with dilute hydrochloric acid solution, and the general cleaning is about 6 hours. If it is cleaned in winter, the solution can be heated to 70-80 ° C to speed up the cleaning speed and improve the cleaning effect. After cleaning the dilute hydrochloric acid solution, drain the liquid and rinse with clean water. In order to prevent acid corrosion, you can cycle with 5% soda solution for 10 minutes, and finally rinse with water.
