Vacuum pumps are widely used, but they also face numerous challenges in practical use.
1. Sealing Issues: Vacuum pumps require extremely high sealing performance. If the seal fails, the pump's efficiency will be significantly reduced.
2. Wear and Lubrication: During operation, friction between the vanes and the inner wall of a rotary vane vacuum pump causes wear. Furthermore, the pump's internal lubrication system requires regular inspection and maintenance.
3. Gas Corrosion and Contamination: The pumped gas may contain corrosive substances or impurities, which can damage the pump's internal structure and shorten its service life.
4. Energy Consumption and Environmental Protection: With growing environmental awareness, reducing vacuum pump energy consumption and emissions has become a key focus in the industry.
