(Summary description)Vacuum pump refers to the use of mechanical, physical, chemical or physicochemical methods to extract air from the container being extracted equipment to obtain a vacuum. Generally speaking, a vacuum pump is a device that uses various methods to enhance, generate and maintain a vacuum in an enclosed space. Due to the wide range of working pressures involved in the vacuum application sector, it is impossible for any type of vacuum pump to be completely suitable for all working pressure ranges. Different types of vacuum pumps can only be used according to different working pressure ranges and different working requirements. To facilitate the use and needs of various vacuum processes, multiple vacuum pumps are sometimes combined according to their performance requirements to form a vacuum unit suitable for that vacuum system.

1. Types of vacuum pumps With the development of vacuum technology in production and scientific The requirements for the application of pressure ranges in the research field are more and more extensive, and most of them must be composed of several vacuum pumps to form a system to meet the requirements of scientific research and production processes. Commonly used vacuum pumps include: dry screw vacuum pump, water ring pump, reciprocating pump, slide valve pump, rotary vane pump, roots pump and diffusion pump, etc. These pumps are the main force for the application of vacuum pump technology in various industries of the national economy of my country. Second, the overall structure of the vacuum pump The structure of the vacuum pump body is divided into: vertical structure and horizontal structure. Vertical Construction: The intake and exhaust ports are placed horizontally, so it is easy to install and connect pipes. However, the pump has a high center of gravity and poor stability at high speed, so it is mainly used for small pumps. Horizontal structure: The air inlet of the pump is at the top and the exhaust port is at the bottom. Sometimes, in order to facilitate the installation and connection of the vacuum system piping, the exhaust port can be connected from the horizontal direction, that is, the directions of the air inlet and the air outlet are perpendicular to each other. Three, the transmission mode of the vacuum pumpThe two rotors of the vacuum pump perform relatively synchronous operations through a pair of high-precision gears. The drive shaft is connected to the motor by a coupling. There are two main types of transmission structure design: one is that the motor and the gear are placed on the same side of the rotor.
