Why regular cleaning screw air compressor cooler? How to clean up after fouling?

Air compressor cooler after long time use, cooler bicarbonate type material such as calcium and magnesium in the water to form scale in them, scale will affect the normal cooler heat transfer, make the air compressor inlet and exhaust temperature, air can not be cooled to a predetermined temperature, affect the quality of compressed air, and even affect the safe operation. So, according to the specific circumstances shall work out a plan for regular cleaning scale.

cleaning scale method has two kinds: one is the mechanical method, also is the physical QingChuFa; The other is a chemical method.

mechanical method is to use a longer handle brush drag back and forth in the tube, eliminate the scale of the tube, also can use water cannons on copper pipe flushing.

chemical method, which is based on the characteristics of scale for alkaline substances commonly, the scale dissolve with dilute hydrochloric acid. But not too high acid content, otherwise it will corrode metal. Specific cleaning method is: first make dilute hydrochloric acid solution, will be 5 ~ 10 kg hydrochloric acid added 100 kg water, dilute hydrochloric acid tank placed at the bottom of the cooler, after another at the bottom of the hose to the water pump, water pump with the passage of the cooler cleaning loop cycle. Pump to start the cycle with dilute hydrochloric acid solution after cleaning, about 6 h general cleaning. If winter cleaning, can heating to 70 ~ 80 ℃, the solution to speed up the cleaning speed, improve the cleaning effect. Dilute hydrochloric acid solution after cleaning, remove the liquid, and then rinse with water, in order to prevent acid corrosion, reusable 5% soda solution circulation, cleaning, 10 min, finally rinse off with clear water.
