Self-priming pump is not the cause of the water absorption is check by artificial damage

self-priming pump suction is not water, self-priming pump is not the cause of the water absorption

guangxi an end-user purchasing my company recently four new pairs of self-priming pump with 4 pump is working in 2 batches purchase 3 units installed in front of the running after normal operation, one behind the spot after installation, the customer reflect as follows:

no. 73 on the left side of the photograph of the machine is the new clothes, the one on the right and no. 74 on the two photo is the original of three sets of the original three have trial run, no problem. The pack three also is according to the original operation operation, but you can't, mainly: self-priming water pump before the start of the filling pump, slightly open the outlet valve, then start, the pressure zero at the moment. Around 25 mpa, although there are fluctuations, but not by much. When we increase the outlet valve opening pump can appear impulse noise, outlet pressure gauge is 0 to 0. Swings between 2 mpa, frequency and pulse noise of water pump is the same, then has been to maintain the phenomenon.

74

according to customer reflect the situation of my working company technical personnel to determine the phenomenon of water is not pumped cavitation phenomenon, through import pipeline to determine customer no leakage phenomenon, carefully observe the photos by the customer, 73 figure on the left side of the new pump inlet flange a short short answer is clearly no spray paint, and ask if the customer is this short answer his replacement: why do you want to change, the results after user understand the installation company was just know, import short indeed been installation company change, change is the scene of the pipe flange and the replacement of the pump flange is not so, replace the sub will involve dynamic check valve, check valve not installed will certainly affect the self-priming pump phenomenon of water absorption, the results show that self-priming pump is not the cause of the water absorption is install check valves are not installed in the company, so the masses of users, please note that don't remove the self-priming pump, please according to the original configuration after removal of self-priming pump installation place.

common self-priming pump related products: stainless steel self-priming pump

in the use of self-priming pump installation of pressure regulating valve control self-priming pump export is recommended when running under the rated parameters.
