What is the Oil Spray in Vacuum Pumps
Oil spray in vacuum pumps refers to the abnormal discharge of lubricating oil from the exhaust port or other parts of the pump during operation. It not only leads to wastage of lubricating oil but can also contaminate the working environment, affect product quality, and even cause equipment damage. Therefore, learning the causes of oil spray in vacuum pumps is crucial for equipment maintenance and fault prevention.
Main Causes of Oil Spray in Vacuum Pumps
1. Excessive Vaucum Pump Oil Level
Excessive oil leads to increased oil mist formation, thus, the discharged will carry excessive oil mist out. In addition, if the oil level exceeds the recommended mark, the rotating parts will easily stir the oil out.
2. Improper Vacuum Pump Oil Selection
Oil viscosity that is too high or too low is not good. Besides, if the volatility of oil is too high, it will easily generate excessive oil mist, which will gather and become oil droplets during the discharge process.
3. Vacuum Pump Exhaust Filter Issues
The oil mist filter is damaged or clogged, thus it cannot work properly. If the filter quality is low, the filtration efficiency is also low, and a lot of oil mist is discharged without being filtered out. For external exhaust filters, it is also necessary to consider whether it is caused by improper installation.
In addition to the above reasons, it may also be caused by overheating of the pump, mechanical failures, improper operation.
In conclusion, oil spray in vacuum pumps is a common issue caused by multiple factors. By understanding its causes and implementing appropriate preventive and corrective measures, the occurrence of oil spray can be effectively reduced, extending equipment lifespan, improving efficiency, and minimizing environmental pollution risks. Regular maintenance and proper operation are the most effective ways to prevent oil spray in vacuum pumps.
