Water ring vacuum pump common troubleshooting method

Add time:2018-09-24 21:32 Hits:

The water ring vacuum pump has the advantages of compact structure, reliable work balance and uniform flow. It is used to transport or pump flammable, explosive and corrosive gases in chemical production, which is efficient and safe, but if it is used improperly, or maintenance Improper, occasionally some faults, let's summarize: What are the common faults and solutions for water ring vacuum pumps.
 
1, the motor is overheated
 
Possible causes: The motor is overloaded and the motor is overloaded; the motor is out of phase; the vent hole is blocked; the impeller drags other components.
 
Remedy: Reduce the water supply to the normal range, refer to the pump supply instructions provided by the pump; check the wiring is firm; check the exhaust port; open the pump cover to adjust the gap between the impeller and other components.
 
2, can not start or start a loud noise
 
Possible reasons: The motor supply voltage of the water ring vacuum pump is insufficient; the motor is out of phase; the pump is used for a long time without causing rust; the pump sucks debris; the impeller drags the distribution plate.
 
Remedy: Check if the power supply voltage is too low; check if the motor wiring is solid; if the pump is not used for a long time, it can add rust remover or open the pump cover to remove rust; open the pump cover to remove debris; adjust the impeller The distance from the distribution board.
 
3, the vacuum pump is not enough
 
Possible reasons: insufficient motor power supply 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; excessive wear of the impeller;
 
Remedy: Check whether the supply voltage of the water ring vacuum pump is within the rated voltage range of the motor; increase the water supply amount (must be controlled within the correct range, otherwise the motor will be overloaded with heat); adjust the gap between the impeller and the distribution plate ( Generally in the 0.15-0.20mm); replace the mechanical seal; replace the impeller; check the pipeline of the outlet.
 
When the water ring vacuum pump fails, be sure to find the cause of the failure. After you understand it, you can think of a suitable solution to solve the problem. You can also learn more about the equipment. So if you encounter similar problems, you know how to solve them without delay.
