Water ring pump common faults and troubleshooting methods

Water ring pump common faults and troubleshooting methods

One, vacuum pump degree is not enough possible reasons: motor power supply is insufficient, resulting in insufficient speed; Insufficient water supply; The gap between the impeller and the distribution plate is too large; Mechanical seal damage resulting in water leakage; Impeller wear too much; Circulating water can't be drained.
Elimination method: check whether the power supply voltage is within the rated voltage range of the motor; Increase water supply (must be controlled in the correct range, otherwise it will lead to motor overload heating); Adjust the clearance between impeller and distribution plate (generally 0.15-0.20mm); Replace the mechanical seal; Replace the impeller; Check the water outlet piping. Two, can not start or start the noise is large possible reasons: motor power supply voltage is insufficient; Motor phase failure operation; The pump is not used for a long time, resulting in corrosion; Pump suction debris; Impeller drag distribution plate. Troubleshooting method: Check whether the power supply voltage is too low; Check whether the motor wiring is firm; If the pump does not lead to corrosion for a long time, you can add a rust remover or open the pump cover to artificially remove rust; Open the pump cover to remove debris; Adjust the distance between impeller and distribution plate. Three, motor overheating possible causes: excessive water supply leading to motor overload; Motor phase loss; The vent being blocked; The impeller dragging other parts. Elimination method: reduce the water supply to the normal range (refer to the pump's operating instructions for liquid supply); Check whether the wiring is firm; Check the exhaust port; Open the pump cover to adjust the clearance between the impeller and other parts. Four, the insufficient flow of possible reasons: pipeline leakage; Resistance loss increases; Elimination method: check the mechanical seal at the joint; Check pipes and check valves for faults.
