Fault phenomenon Possible causes exclusion method 1. The water pump is not producing water a. The import and export valves are not open, and the inlet and outlet pipelines are blocked Impeller flow channel blockage b. Motor running direction incorrect, slow motor speed due to phase loss c. Leakage in suction pipe d. Pump not filled with liquid There is air in the pump chamber. The water supply to the inlet is insufficient, and the suction stroke is too high Excessive resistance in the bottom valve leakage pipeline. Improper pump selection a. Check and remove blockages. Adjust the motor direction Tighten the motor wiring and tighten all sealing surfaces Remove air. d. Open the exhaust valve to exhaust all air. e. Stop the machine for inspection Adjust (grid connected water pipes and those with suction ports are prone to this phenomenon) f. Reduce pipeline bends Re select pump 2. Insufficient water pump flow a. Firstly, check the cause. b. Pipeline, pump channel or impeller blockage Insufficient valve opening for scale deposition c. Low voltage d. Damaged impeller a. First, press 1. Remove b. Remove blockages Adjust the valve opening again, c. stabilize the pressure, d. replace the impeller 3. Excessive power a. Exceeding the rated flow for use b. Excessive suction c. Wear of pump bearings a. Adjust the flow rate, turn down the outlet valve b. Lower the suction height c. Replace the bearing 4. Noise vibration a. The pipeline support is unstable. b. The liquid is mixed with gas. c. Cavitation occurs. d. Bearing damage. e. Motor overload operation a. Stabilize the pipeline b. Increase suction pressure and exhaust c. Reduce vacuum degree d. Replace bearings e. Adjust according to 4 5. The water pump motor is heating up a. Excessive flow, overloaded operation b. Local friction c. Motor bearing damage d. Insufficient voltage a. Close the outlet valve. b. Check and eliminate. c. Replace the bearing. d. Stabilize the pressure 6. Water pump leakage a. Mechanical seal wear b. There are sand holes or cracks in the pump body c. The sealing surface is uneven d. The installation bolts are loose a. Replace b. Weld or replace c. Repair d.
