Water ring vacuum pump failure and solution

During the inspection and repair process, the diagnosis of the water ring vacuum pump fault is a key link. The following describes the liquid ring vacuum pump is not provided with liquid, the supply of liquid is insufficient or the pressure is insufficient and the solution and hope that everyone can carry out a targeted water ring vacuum pump. Fault diagnosis, solve the problem as soon as possible.

1. The vacuum pump has no water or proper exhaust; Solution: Check that the vacuum pump housing and inlet line are completely filled with liquid.

2. The speed is too low; Solution: Check whether the wiring of the motor is correct, whether the voltage is normal or whether the steam pressure of the turbine is normal.

3. System head is too high; Solution: Check the system's head (especially friction loss).

4. Suction lift is too high; Solution: Check the existing net head (too small or too long inlet line will cause great friction loss).

5. The impeller or pipeline is blocked; Solution: Check for obstacles.

6. The direction of rotation is incorrect. Solution: Check the direction of rotation.
