The suction system of medical center is made up of vacuum pump unit of central suction station as negative pressure source. The suction system can make the suction system pipeline reach the required negative pressure value through vacuum pump suction. It generates suction at the terminal of opera...

liquid ring vacuum pump is a kind of coarse vacuum pump. The limit vacuum it can obtain is 2000-4000Pa. The vacuum degree of the unit composed of Roots vacuum pump and liquid ring vacuum pump can reach 1-600Pa. liquid ring vacuum pump can also be used as a compressor, called water ring compressor...

The 2XZ rotary vane vacuum pump is mainly composed of pump body, rotor, rotary vane, end cover, spring and so on. A rotor is eccentrically installed in the cavity of the rotary vane pump. The outer circle of the rotor is tangent to the inner surface of the pump cavity (there is a small gap betwee...

Vacuum pump is a device that produces, improves and maintains vacuum in a closed space by various means. Vacuum pump can be defined as: mechanical, physical, chemical or physicochemical methods to be pumped by the container to obtain a vacuum device or equipment. With the development of vacuum ap...

What is vacuum pump oil？ Vacuum pump oil is a kind of lubricating oil specially developed for vacuum pump on vacuum equipment. It is divided into mineral oil and synthetic oil. Vacuum pump performance characteristics: Oxidative stability: long-term high temperature with air, resin, chemical raw ...

At present, the development of various vacuum pumps is increasingly affected by vacuum applications. The general vacuum system can not meet the requirements of clean, oil-free and corrosion-resistant. Therefore, in recent years, the market demand of dry vacuum pumps is very large. Vacuum products...

Vacuum has always been a distant field, until the 21st century is this time, the use of vacuum field is gradually familiar to people, the meaning of vacuum is a given space under the pressure of a gas state, is a physical phenomenon. In the void, sound cannot be transmitted because there is no me...

The structure of rotary vane pump is customarily divided into “oil immersed” and “oil sealed”. The former refers to the pump body immersed in the tank, its advantages are: many parts and components that require air tightness can be sealed by oil; easy to set up to prevent ...

Failure of any oil diffusion pump vacuum system may affect the performance or production capacity of the equipment. Misoperation of any valve will cause the diffuser pump oil to return to the vacuum chamber, thus polluting the vacuum chamber and products. Leakage holes in the preceding pipeline, ...

With the improvement of the national consumption level, the demand for a large number of daily necessities is increasing, and the development of transportation is convenient. It also breaks the restriction of regional space. At the same time, the requirement for vacuum products is becoming more a...
