Some Important Knowledge for You about the Classification and Properties of Vacuum Pump

In recent years, humans have developed a new kind of new Vacuum Pump. From atmospheric pressure to high vacuum, it only need a pump can achieve the goal expected before. But generally speaking, in order to obtain high vacuum, super high vacuum and extreme height vacuum, or series of multiple vacuum pump unit form to complete the pumping task. Therefore, the correct understanding of the working principle, main properties, characteristics of pump structure and classification is very important for the user to select the economic application of the vacuum pump. The rotary vacuum pump is a device, which can be used to produce, improve and maintain the vacuum. According to its working principle, it can be basically divided into two types that the gas transmission pump and gas trapping pump.


Gas transmission pump is a kind of vacuum pump, which can make the gas suction and discharge pump to vacuum pump suction. The gas transmission pump contains two categories of volume pump and momentum transfer pumps. Gas transmission pump include: liquid ring vacuum pump (water ring vacuum pump), reciprocating vacuum pump, rotary vacuum pump, stator type rotary vacuum pumps, vacuum pump, trochoidal water ring vacuum pump, dry-type vacuum pump, roots vacuum pump, vacuum pump, molecules molecular drag pump, compound vacuum pump, a water jet vacuum pump, gas jet pump, steam jet pump, and diffusion pump. This type of pump has been widely used in the fields of metallurgical, mechanical, electronic, chemical, petroleum, pharmaceutical and other industries for vacuum metallurgy, vacuum coating, vacuum heat treatment, vacuum drying processes.
Trapping gas pump is a kind of vacuum pump, which can make a gas molecules assorted or condensate inside the pump at the surface. Thereby reducing the container, there are a number of gas molecules need to achieve the purpose of the exhaust vacuum pump. It has the following pattern: adsorption pump, getter pump, getter pump, cryogenic pumps etc. There are still leaving some residual gas in high vacuum oil diffusion pump, and 80% of those are water steam, oil and other high boiling steam.
Besides its pumping capacity, there are other disadvantages like low residual gas, long time work, and have the residual gases or the source of pollution, which can make the yield and quality of products be affected. Gas capture pump is a good choice to solve this kind of problem.
All in all, when you are choosing these kinds of products, you need to pay much attention to vacuum pump manufacturer, which can give you a good security.
