Insufficient air volume

1. Leakage of piping system

2. Increased clearance

3. Import clogging

4. Belt slip speed is not enough

1. Tighten all joints and repair leak   components

2. Adjust the clearance or replace the   rotor

3. Cleaning filter

4. Adjust belt tension or replace new   belt

Motor overload

1. Import resistance

2. Boost increase

3. The impeller has friction with the   cylinder wall

4 fan speed is high

5. Too much water in the wet vacuum pump

1. Clean the filter

2. Check exhaust pressure and load   conditions

3. Adjust the gap

4. Replace the pulley

5. Reduce the amount of sealed water

Overheating

1. Boost pressure increase

2. The impeller has friction with the cylinder   wall

3. Too much or too little lubricant

4. Poor oil quality

5. The amount of water enclosed by the   wet vacuum pump is not enough

1. Check the inlet and exhaust pressure   and load conditions

2. Adjust the gap. For wet vacuum pumps,   decompose and remove rust

3. Control oil level

4. Replace with new oil

5. Increase the amount of sealed water

Disturbance

 1.   Misalignment of synchronous gears and rotors

2. Serious bearing wear

3. Large fluctuations in boost pressure

4. Gear damage

5. Safety valve opens and closes   repeatedly

6. Check valve damage

7. Wet vacuum pump is too much water,   such as the sound of water

1. Corrected according to the specified   position, locked

2. Change bearing

3. Check the pipeline and load

4. Change gear

5. Check for overpressure or adjust   safety valve

6. Replacement

7. Reduce the amount of sealed water

The

Unable to move

1. Into the exhaust port is blocked or   the valve is not open

2. The wrong motor wiring or other   electrical problems

1. Remove the blockage or open the valve

2. Check the wiring or other electrical   appliances

Leakage of lubricant

1. The oil level is too high

2. Seal failure

1. Control oil level

2. Change the seal

Large vibration

1. The foundation is unstable

2. Bearing wear

3. Misalignment of motor and fan

1. Reinforced, firmly secured

2. Change bearing

3. Follow the instructions to find
