Vacuum pumps play an important role in food packaging and processing. Vacuum packaging can extend the shelf life of food, reduce oxygen exposure, and prevent food oxidation and spoilage. Meanwhile, in the food processing process, vacuum pumps are used for degassing and concentration, improving the quality and taste of food. In the semiconductor production process, a vacuum pump is used to provide an ultra-high vacuum environment to ensure the smooth progress of process operations such as thin film deposition and ion implantation. Vacuum pumps are used to simulate space environments and test the performance and reliability of aerospace devices.

Vacuum pump, as a device that uses mechanical, physical, chemical or physicochemical methods to extract air from the container being pumped to obtain a vacuum environment, plays a crucial role in industrial production. It is widely used in various fields such as metallurgy, chemical industry, food, electronic coating, and aerospace, and has become an indispensable part of modern industry.
