The simplicity of the vacuum pump

Vacuum pump refers to a device or equipment that uses mechanical, physical, chemical or physicochemical methods to pump the pumped container to obtain vacuum. Generally speaking, a vacuum pump is a device that improves, generates and maintains vacuum in a closed space by various methods.
According to the working principle of vacuum pump, vacuum pump can be basically divided into two types, namely gas capture pump and gas transmission pump. It is widely used in metallurgy, chemical industry, food, electronic coating and other industries.
