Common troubles of water ring vacuum pump

Water ring vacuum pump in use after a period of time there will be some failures, water ring vacuum pump common failures?

1、 Insufficient water ring vacuum pump

Possible causes: insufficient power supply of motor leads to insufficient speed; insufficient water supply; excessive clearance between impeller and distribution board; mechanical seal damage leads to water leakage and air leakage; impeller wear is too much; circulating water cannot be discharged.

Troubleshooting: check whether the power supply voltage is within the rated voltage range of the motor; increase the water supply (it must be controlled within the correct range, otherwise the motor will be overloaded and heated); reduce the clearance between the impeller and the distribution board (generally 0.15-0.20mm); replace the mechanical seal; replace the impeller; check the pipeline at the water outlet.

2、 It can't be started or it's noisy

Possible causes: insufficient power supply voltage of the motor; lack of phase operation of the motor; corrosion of the water ring vacuum pump due to long-term failure; suction of debris in the pump; impeller drag distribution board.

Troubleshooting: check whether the power supply voltage is too low; check whether the motor wiring is reliable; if the pump is not used for a long time, add a little rust remover or open the pump cover to remove the rust manually; open the pump cover to remove the sundries; adjust the distance between the impeller and the distribution board.

3、 Motor overheating

Possible causes: motor overload due to excessive water supply; motor phase loss; exhaust hole blockage; impeller driving other components.

Troubleshooting: reduce the water supply to the normal range (refer to the pump's operating instructions for the liquid supply); check whether the wiring is firm; check the exhaust port; open the water ring vacuum pump cover to adjust the clearance between the impeller and other components.

4、 Insufficient flow

Possible causes: pipeline air leakage and liquid leakage; increase of resistance loss;

Troubleshooting: check the mechanical seal at the connection; check the pipeline and check valve for failure.

The above is the main reason for the common failure of water ring vacuum pump.
