1. If there is no supply of liquid, or the supply of liquid and pressure is insufficient.

If the vacuum pump is not filled with water or exhausted.

Solution: Need to check the housing and inlet pipeline of the vacuum pump

The speed is too low

Solution: Need to check the wiring out of the motor, the voltage and the steam pressure of the turbine.

System head too high

Solution: Check the head of the friction loss.

The adsorption capacity is too high.

Solution: Check the existing pure pressure head (if the inlet pipe is too small or too long, it will produce greater friction loss)

Impeller and pipe blockage

Solution: Check whether there are any obstacles.

Wrong direction of rotation

Solution: Check the direction of rotation.

Check the inlet line for leaks.

Solution: Whether there is leakage in the inlet pipeline.

The sealing ring and seal in the sealing ring are worn, causing the vacuum pump housing to leak.

Solution: check the seal when necessary to replace, check whether the lubrication is normal.

Insufficient suction head when sucking starting liquid;

Solution: Need to increase the suction head.

Bottom valve too small

Solution: Install the bottom valve according to the correct size. Insufficient immersion depth of foot valve or inlet pipe

Solution: Use the correct immersion depth.

The clearance of the impeller is too large

Solution: Check the gap position

Damaged impeller

Solution: Check the impeller and replace it if necessary.

The diameter of the impeller is too small

Solution: Use the correct impeller diameter.

Incorrect position of pressure gauge.

Solution: Need to check the outlet nozzle or pipe.

2. The vacuum pump stops running for a while.

The adsorption capacity is too high

Solution: Check the existing pure pressure head (if the inlet pipe is too small or too long, it will produce greater friction loss)

Impeller and pipe blockage

Solution: Check for obstacles.
