Analysis of Causes of Vacuum Pump Insufficiency and Remedy

I. Insufficient supply of vacuum pumps leads to insufficient speed; insufficient water supply; excessive clearance between the impeller and the distribution plate; leakage of water leakage due to mechanical seal damage; excess impeller wear;

If this happens, then the corresponding solution is: check the power supply voltage is within the rated voltage range of the motor; increase the amount of water supply (must be controlled within the correct range, otherwise it will lead to motor overload heat); small impeller and Distribution plate clearance (usually 0.15-0.20mm); change the mechanical seal; replace the impeller; check the outlet pipe

Second, the vacuum pump can not start or start the noise

Possible causes: The motor power supply voltage is insufficient; the motor runs out of phase; the pump is not used for a long time to cause corrosion; the debris is sucked in the pump;

If this happens, then the corresponding solution: check the power supply voltage is too low; check the motor wiring is solid; if the pump is not used for a long time to cause corrosion can add a little rust Remover or open the pump cover to artificially remove rust; Open the pump cover to remove debris; adjust the distance between the impeller and the distribution plate.

Third, the vacuum pump motor overheating problem

Possible causes: Overloading of the motor leads to overload of the motor, phase loss of the motor, blockage of the exhaust hole, and dragging of the impeller to other components.
