Generally speaking, a vacuum pump is a device that improves, generates, and maintains a vacuum in a closed space by various methods. According to the working principle of the vacuum pump, the vacuum pump can basically be divided into two types, namely gas capture pumps and gas transfer pumps. It is widely used in industries such as metallurgy, chemical industry, food, and electronic coating.

A support assembly is installed on the top of the support plate, and a vacuum pump is installed on the support assembly. An annular groove is formed on the top of the bottom plate, a protection cover is installed on the top of the bottom plate, and two connection assemblies are installed on the bottom plate. The utility model is convenient for better protecting the vacuum pump unit and is convenient for better disassembling and assembling the protection device, achieving better disassembly and assembly efficiency.

[0004] Although the above patent technology can better protect the vacuum pump unit and is convenient for better disassembling and assembling the protection device, achieving better disassembly and assembly efficiency, during the installation and disassembly process, the vacuum pump needs to be always inside the protection cover, which is likely to affect the installation and disassembly efficiency. Therefore, a protection device for a new type of Roots screw vacuum pump unit is needed to solve the above problems. Content of the Utility Model
