Vacuum pump according to the working principle of classification

According to the working principle of vacuum pump, vacuum pump can basically be divided into two types, namely, gas transmission pump and gas trap pump. With the vacuum application technology in the field of production and scientific research more and more wide range of its application pressure, most of the need to be composed of several vacuum pump vacuum exhaust system together to meet the production and scientific research process requirements, therefore Selection of different types of vacuum pump composed of vacuum extraction unit more often. For the sake of convenience, it is necessary to classify these pumps in some specific detailed categories according to their working principle or their structural features.
