water ring vacuum pump troubleshooting
In the use of the water ring vacuum pump, because of the incorrect operation mode or the lack of good maintenance in use, it is quite normal that some problems occur in the use of the equipment, but sometimes the occurrence of a fault is not only caused by one reason, which requires us to carry out effective troubleshooting and solve all the faults in a timely manner.
1、 The reason for the failure is that the motor power supply is insufficient, resulting in insufficient speed and water supply; the gap between the impeller and the distribution plate of the water ring vacuum pump is too large; the mechanical seal is damaged, resulting in water leakage and air leakage; the impeller is worn too much; the 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; reduce the gap between the impeller and the distribution board; replace the mechanical seal; replace the impeller; check the pipeline at the water outlet.
2、 The possible reasons for the failure to start or the noise is that the power supply voltage of the motor is insufficient; the motor lacks phase operation; the pump is not used for a long time, resulting in corrosion; the water ring vacuum pump sucks in sundries; the impeller drags the 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、 The possible causes of motor overheating are motor overload caused by excessive water supply, motor phase loss, exhaust hole blockage, impeller dragging other components.
Troubleshooting: reduce the water supply to the normal range; 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、 The possible causes of insufficient flow are air leakage and liquid leakage of pipeline, increase of resistance loss;
Troubleshooting: check the mechanical seal at the connection; check the pipeline and check valve for failure.
Using these troubleshooting methods of water ring vacuum pump will also help you to conduct troubleshooting work quickly, so that the speed of normal use of the equipment will be accelerated, and more losses will be avoided.
