Faults and Treatment Measures of Roots Blower in Use

What are the faults and treatment measures of Roots blower in use?

Insufficient air volume

1. Air leakage of pipeline system

2. The clearance increases

3. The inlet is blocked

4. The belt slipping speed is not enough. 1. Fasten all connectors and repair the air leakage parts

2. Adjust the clearance or replace the rotor

3. Clean the filter

4. Adjust the belt tension or replace with a new belt

Motor overload 1. Large inlet resistance

2. Increase of pressure rise

3. Friction between impeller and cylinder wall

4. Fan speed is too high

5. Excessive seal water of wet vacuum pump 1. Clean the filter

2. Check the exhaust pressure and load

3. Adjust the clearance

4. Replace the pulley

5. Reduce sealed water volume

Overheating 1. Increase of pressure rise

2. Friction between impeller and cylinder wall

3. Too much or too little lubricating oil

4. Poor oil quality

5. The water volume of wet vacuum pump seal is not enough 1. Check the inlet and exhaust pressure and load conditions

2. Adjust the clearance. For wet vacuum pump, disassemble and remove rust

3. Control the oil level of the oil pointer

4. Replace with new oil

5. Increase sealing water volume

Abnormal noise 1. The position of synchronous gear and rotor is misadjusted

2. The bearing is severely worn

3. Large pressure rise fluctuation

4. Gear damage

5. Repeated opening and closing of safety valve

6. The check valve is damaged

7. The seal of wet vacuum pump has too much water, such as water splashing sound 1. Correct according to the specified position and lock it

2. Replace the bearing

3. Check the pipeline and load

4. Change gears

5. Check for overpressure or adjust the safety valve

6. Replace

7. Reduce sealed water volume

Unable to start 1. The air inlet and outlet are blocked or the valve is not opened

2. Incorrect motor wiring or other electrical problems 1. Remove the blockage or open the valve

2. Check the wiring or other electrical appliances

Lubricating oil leakage 1. The oil level is too high

2. Seal failure 1. Control the oil level of the oil pointer

2. Replace the seal

Large vibration 1. The foundation is unstable

2. Bearing wear

3. Motor and fan are misaligned 1. Reinforce and fasten

2. Replace the bearing

3. Align according to the instructions
