Dry screw vacuum pump can pump out the gas containing a large amount of water vapor and a small amount of dust, so what kind of structure does it have? Let’s take a look at it. The transmission shaft is connected with the active rotor, and the driven rotor is driven to rotate by the synchro...

Factory liquid ring vacuum pump principle and structure characteristics The liquid ring vacuum pump belongs to the mechanical centrifugal pump, and the impeller rotor is eccentrically installed in the cylindrical pump shell. When the impeller rotates under the drive of the motor, the working flui...

1. Vacuum: in vacuum science, the meaning of vacuum refers to the state of gas below an atmospheric pressure in a given space. People usually call this thin gas state vacuum state. 2. Vacuum degree: as the name implies, vacuum degree is the degree of vacuum. The thinness of gas in vacuum state is...

The use of vacuum pump in school laboratory is more and more common. Most laboratory equipment will be equipped with vacuum pump. Because vacuum pump is not a single equipment, it can be used with other instruments. Such as vacuum filtration, microbial detection, waste liquid extraction, rotary e...

It is suitable for th...

Water ring vacuum pump is a kind of vacuum equipment. Usually, when we use it, we often add oil for lubrication, but in the long-term use process, there will be oil return. Specifically, the oil vapor is affected by the temperature and attached to the original piece, which will not only cause was...

It is very important to choose the pump speed ratio between roots vacuum pump and front stage pump for the composition of roots screw vacuum unit. Because the compression ratio of Roots vacuum pump is very limited. This compression ratio determines the capacity of the previous stage pump because ...

Today I will tell you how to operate the liquid ring vacuum pump in the vacuum system. According to the after-sales service feedback report, we have made statistics on the failure analysis of the liquid ring vacuum pump in the last year, and found that very few of them are caused by the quality p...

Corrosion resistant vacuum pump purpose and scope of use The anti-corrosion vacuum pump is the second generation of improved type, which is specially used to pump or press corrosive gas without solid particles, so as to form vacuum or pressure in the container and meet the requirements of specifi...
