The reason that the water discharge pump does not pump water or water is small

Fault phenomenon: after diving sewage pump running, the three phase current of diving sewage pump motor is normal, and the power also have no problem, then without water or water yield small diving sewage pump should be according to the following method to find the diving sewage pump is not the cause of the water:
Newly purchased diving sewage pump is started for the first time if there is a phenomenon of diving sewage pump no water or water yield small, at this time should be to check if the motor is reversed in a reversal phenomenon is causing diving sewage pump is not the cause of the water or water yield small;The position of the two phase cables should be changed arbitrarily, and the solution can be solved.There is also the reason that the submersible pump does not discharge water, it is possible that the head of the submersible sewage pump can not reach the required working conditions, and the selection of the other series of sewage pump should be replaced.It is possible that the exit of the sewage pump with the coupler bad joint pipe flange sealing leak of the old type usually diving sewage pump coupler's seal leakage phenomenon, to avoid this kind of phenomenon suggest selecting new large submersible pump can eliminate, the movement of water hose under the sewage pump pressure lead to a water pipe burst phenomenon will be diving sewage pump water yield little.Another possibility is conveying fluid is corrosive, sewage pump impeller and other components of any encounter traffic head after corrosion parameters, this kind of circumstance suggests it is advisable to choose stainless steel submersible pump products.
Use longer time diving sewage pump, if appear the phenomenon of water yield is more and more small, may be diving sewage pump impeller wear after long time use of reason, then should replace the new impeller parts.It is also possible that diving sewage pump imports and blocked inside the pump body and affect the water suction, should clean up the pump body or filter parts at this moment, with stir function or beaten sewage pump automatically.
Diving sewage pump motor is normal, but the current is very small, and diving sewage pump is not water, this phenomenon is likely to be sewage pump pump shaft has been broken, then should put the motor with the disintegration of sewage pump repair, replace the motor rotor.
