What are the solutions for smoking and oil spraying in vacuum pumps?

Summary: 1. Smoking: If smoking occurs right after the pump is first started up, this is normal. However, if smoking persists for an extended period, it’s abnormal. The solution: Smoking indicates that there’s a repair or leak somewhere outside the pump’s intake port—such as in the pipelines, valves, or containers. Once the leaks are located and repaired, the smoking will stop. 2. Oil喷射: This indicates numerous leaks outside the intake port, possibly even with the intake port directly exposed to the atmosphere. The solution: Seal the pump’s intake port and run the pump. If no oil is sprayed, it means there’s a leak. Alternatively, the exhaust valve flap may be damaged; check whether the exhaust valve flap is broken and replace any damaged flaps.
1. If smoke is observed shortly after the pump starts up, this is normal. However, if smoke persists for an extended period, it’s abnormal.

Once the leaks are identified and repaired, the smoking will stop.
2. If oil is not being injected, it indicates that there are significant leaks around the intake port—or even that the intake port is exposed directly to the atmosphere. The solution: Seal the pump’s intake port and run the pump. If no oil is injected, this confirms the presence of leaks. Alternatively, the exhaust valve flap may be damaged; check whether the exhaust valve flap is damaged and replace any defective flaps.
