Vacuum pump of oil filter

In the method of obtaining vacuum, people usually call the equipment that can discharge gas from the closed container or reduce the number of gas molecules in the container as the vacuum acquisition equipment or vacuum pump. At present, in vacuum technology, various methods have been used to obtain and measure the pressure range from 105Pa to 10-13pa, which is up to 18 orders of magnitude wide. Obviously, it is difficult to obtain such a wide space of low pressure by using vacuum pump alone. High efficiency vacuum oil filter can obtain vacuum under the action of vacuum pump.

At present, there are two kinds of vacuum acquisition technology. The other is to adsorb or condense gas molecules on low temperature surface by physical and chemical methods. There are many kinds of vacuum pumps manufactured by these two methods, and their classification methods are also different. But the most commonly used method is to classify the vacuum pump according to its working principle or structural characteristics.


According to the working principle of vacuum pump, vacuum pump can be basically divided into two types, namely gas delivery pump and gas capture pump. The demand pressure of production and scientific research in the field of vacuum application technology is becoming wider and wider. Most of them need the process that several common vacuum pumps can meet the needs of production and scientific research. Therefore, different types of vacuum pump and vacuum oil filter are selected. For convenience, it is necessary to classify these pumps according to their working principle or structural characteristics.
