Gas pump including

Pumping the container using mechanical, physical, chemical, physical and chemical method, in order to obtain and maintain a vacuum device. Vacuum manual gas pump and other equipment (such as a vacuum container, vacuum valve, vacuum measuring instruments, the connection pipelines) consists of vacuum system, widely used in electronics, metallurgy, chemical industry, food, machinery, pharmaceuticals, aerospace and other departments. According to its working principle, basically divided into portable fuel gas transfer pump and pump gas trapping two types.
Widely used in chemical, food, building materials and other departments, especially in a vacuum crystallization, drying, filtration, evaporation and other processes more appropriate. Rotary vane vacuum pump is used for extraction is one of the basic equipment of gas container. It can be used alone, can also be used as a booster pump, diffusion pumps, molecular pump. This type of pump is widely used in metallurgical, mechanical, electronic, chemical, petroleum, pharmaceutical and other industries for vacuum metallurgy.
