The cause of the malfunction Remedy No water pump 1, the pump can be less than the lack of liquid or liquid storage 2, suction pipe leakage 3, the speed is too low 4, the suction stroke is too high or too long suction pipe 5, the mechanical seal leakage is too large 6, the suction pipe gas can not be discharged from the outlet 1, plus enough liquid storage 2, check and eliminate air leakage 3, adjust the speed 4, reduce suction or shorten the suction pipe 5, repair or replace 6, make it discharge noise and Large vibration 1, unstable feet 2, pump shaft bending 3, cavitation 4, serious bearing wear 5, there are impurities in the inlet pipe 6, both the pump and motor spindle heart 1, reinforcement 2, replacement or Calibration 3, adjust the working conditions 4, replace 5, remove debris 6, adjust the coaxiality The amount of water is less than 1, the impeller runner and suction pipe is blocked 2, impeller or impeller seal wear and tear 3, power shortage or speed is too low 1 , Exclude blockage 2, replace the split ring 3, add enough power, adjusted to the rated speed shaft power consumption is too large 1, the flow is too large 2, the speed is too high 3, the pump shaft bending or impeller card collision 4, the pump flow blockage Or stuck 1, increase the outlet pressure 2, appropriate to reduce 3, replacement or correction 4, eliminate the block Thing
