Working principle of common vacuum pump
Jun 24, 2022| Working principle of common vacuum pump
Vacuum pumps require high-speed and efficient removal of gas from a sealed container to achieve the purpose of creating, improving, and maintaining a vacuum. Its working principle can be divided into mechanical, physical, and chemical methods. According to the degree of vacuum to achieve differently, often need more than two kinds of vacuum pump phase combination.
Represents the vacuum pump
1: rotary mechanical pump
2: Molecular pump (TMP)
3: ion pump
4: Ti sublimation pump
5: cryogenic pump
Oil diffusion pumps, once widely used, are rarely used now because of the problem of oil and gas evaporation.
