Common faults and troubleshooting methods of oil purifier vacuum pump

The vacuum pump is very important in the oil filter. Common faults and solutions are as follows:

1. Insufficient vacuum

- Cause:

- Aging or damage of seals

- Insufficient or contaminated vacuum pump oil

- Leakage in the intake pipe

- Solution:

- ｒｅｐｌａｃｅ seals

- Replenish or ｒｅｐｌａｃｅ vacuum pump oil

- Check and repair the intake pipe

2. Overheating of vacuum pump

- Cause:

- Failure of cooling system

- Insufficient or deteriorated vacuum pump oil

- Long-term high-load operation

- Solution:

- Check and repair the cooling system

- Replenish or ｒｅｐｌａｃｅ vacuum pump oil

- Proper shutdown for cooling

3. Excessive noise

- Cause:

- Wear of internal parts of vacuum pump

- Insufficient or contaminated vacuum pump oil

- Unstable installation

- Solution:

- Check and ｒｅｐｌａｃｅ worn parts

- Replenish or ｒｅｐｌａｃｅ vacuum pump oil

- Reinstall and reinforce

4. Emulsification of vacuum pump oil

- Cause:

- Excessive water in the oil

- Poor quality of vacuum pump oil

- Solution:

- ｒｅｐｌａｃｅ the vacuum pump oil and check oil separator

- Use high-quality vacuum pump oil

5. Vacuum pump is difficult to start

- Cause:

- Unstable power supply voltage

- Stuck inside the vacuum pump

- High viscosity of vacuum pump oil

- Solution:

- Check and stabilize power supply voltage

- Check and clean internal parts

- ｒｅｐｌａｃｅ low-viscosity vacuum pump oil

6. Smoke coming out of the vacuum pump exhaust port

- Cause:

- Excessive vacuum pump oil

- Severe contamination of vacuum pump oil

- Solution:

- Adjust oil level to normal range

- ｒｅｐｌａｃｅ vacuum pump oil

7. Vacuum pump oil consumption is too fast

- Cause:

- Damaged seal

- Vacuum pump oil leakage

- Oil separator failure

- Solutions:

- ｒｅｐｌａｃｅ seals

- Check and repair leaks

- Check and repair oil separators

8. Vacuum pump is unstable

- Causes:

- Unstable power supply voltage

- Wear of internal parts of vacuum pump

- Insufficient or contaminated vacuum pump oil

- Solutions:

- Check and stabilize power supply voltage

- Check and ｒｅｐｌａｃｅ worn parts

- Replenish or ｒｅｐｌａｃｅ vacuum pump oil

Common vacuum pump failures include insufficient vacuum, overheating, excessive noise, oil emulsification, difficulty starting, smoke from the exhaust port, excessive oil consumption and unstable operation. Solutions include replacing seals, replenishing or replacing vacuum pump oil, checking and repairing leaks, cleaning internal parts, stabilizing power supply voltage, etc. Regular maintenance and inspection can effectively prevent and solve these problems.
