What are the causes of leakage of circulating water pumps in spray towers?

　　Shower tower circulating water pump is a kind of vertical centrifugal pump made of engineering plastics PP/PVDF injection molding, with acid and alkali corrosion resistance, oxidation resistance, no water can be idling characteristics, more used in the field of waste gas treatment in the exhaust gas tower, painting, biological deodorization, pickling, printing and dyeing, circuit boards, the electronics industry, and many other fields, the shower tower circulating pump in the use of water leakage in the process of what are the reasons for the cause of the leakage?

　　Booting and running water leakage (plastic vertical pump for exhaust gas treatment tank outside the installation) the reason analysis:

　　1, the liquid level in the tank is too high, more than the motor, is due to the installation is not planned, adjust the installation height of the plastic vertical pump, the liquid level is located in the 1/2 of the pump head can be.

　　2、The head is high and the outlet is clogged. (There are welding rod slag, foreign objects clogging the spray head. The reason is that the flux tank is not cleaned up, small foreign objects with the pump to reach the shower head caused by clogging, before use to clean the flux tank)

　　3, you choose the supplier selection is not allowed, resulting in too large a flow, the exit flow is not urgent, the pressure is too high. (Choose Meibao environmental protection will not be wrong)

　　4, the use of a period of time to replace the liquid in the tank in a timely manner, the concentration of the potion will be higher and higher with the use of time, a long time without replacement, the spray tower welding points will appear oozing liquid crystallization phenomenon.

　　Leakage during shutdown (plastic vertical pump for exhaust gas treatment tank outside the installation)

　　1、The liquid level of the tank is too high, the liquid in the pipeline flows back, and the liquid level of the storage tank rises above the upper limit of water storage in the tank.

　　2、In the case of too high a head, the stopper will appear, the liquid reflux is not timely leakage, it is recommended to install a check valve to extend the service life.

　　3, add the check valve, but also leakage, check valve has a sphere, flip-flop type, hemispherical three cases, flip-flop hemispherical type will appear sealing is not tight, resulting in liquid reflux, leakage of water. (Mabel check valve adopts sphere type, good sealing)
