The influence of vacuum pump oil pollution on pump performance is mainly reflected in the following aspects:

1.Reduced vacuum: Contaminated vacuum pump oil can affect the sealing performance of the pump, resulting in gas leakage, which reduces the ultimate vacuum level of the vacuum pump, preventing the desired vacuum level to be reached.

2.Increased wear: Contaminants  can circulate inside the pump, causing increased wear and tear on mechanical components and shortening the life of the pump.

3.Frequent oil changes: Oil contamination can lead to the need for more frequent oil changes, increased maintenance costs, and can cause environmental pollution.

4.Affect the performance of the oil mist filter: Contaminated oil will increase the filtration load of the oil mist filter, resulting in poor exhaust air, increased exhaust pressure, and may even lead to filter rupture.

5.Blockage of internal pathways: Contaminants may enter the pump body, clogging the oil and gas circuits, resulting in a decrease in the efficiency of the vacuum pump or even a failure.

6.Deterioration of oil quality: Long-term use of contaminated vacuum pump oil will lead to oil deterioration, emulsification or carbonization, affecting the lubrication and sealing performance of the pump.

7.Increased energy consumption: Due to the deterioration in the performance of the vacuum pump, the pump needs to consume more energy to maintain the required vacuum level while operating, resulting in increased energy consumption.

8.Impact on product quality: In some applications, such as pharmaceuticals and food processing, contamination of vacuum pump oil can lead to a deterioration in the quality of the final product or even a safety hazard.

Therefore, regular inspection and replacement of vacuum pump oil to ensure the cleanliness and performance of the oil is essential to maintain the normal operation of the vacuum pump and extend its service life.
