screw vacuum pump analysis and advantage introduction

The use and advantages of the screw vacuum pump are described. First, the use of the screw vacuum pump is described. The two screws of the screw vacuum pump are calibrated by precise dynamic balancing, supported by bearings. The device is in the pump shell, and there is a certain gap between the screw and the screw. Therefore, when the pump is working, there is no friction between them, the operation is stable, the noise is very low, and the working cavity does not need smooth oil, The dry screw vacuum pump can pump out the gas place which contains a lot of water vapor and a small amount of dust. It has the advantages of higher limit vacuum, lower power consumption, energy saving and maintenance free. It is an updated product of oil sealed vacuum pump.

Then analyze the advantages of screw vacuum pump. At present, the development of various vacuum pumps is more and more affected by vacuum applications. The general vacuum system cannot meet the requirements of clean, oil-free and corrosion-resistant. Therefore, in recent years, the market demand of dry vacuum pump is large, and the vacuum products have been updated, A large number of oil vacuum systems have been replaced by oil-free clean vacuum systems. Almost every large foreign vacuum company produces various types of dry vacuum pumps. Screw vacuum pump is a non-contact dry pump, which is an ideal pump in the early 1990s. It is widely used for its wide pumping speed range, simple and compact structure, no friction, long life, low energy consumption, no oil pollution and other advantages.

Due to its superior performance, dry screw vacuum pump has become the first choice of vacuum obtaining equipment in microelectronics, semiconductor, pharmaceutical, precision processing and other industries in Europe, America and Japan. Based on screw compressor, Japan has long developed the multi rotor profile of vacuum pump and put it into the market. Several vacuum equipment companies in Germany have gradually developed equal pitch and variable pitch rotor profiles, and have done a lot of research on rotor and body cooling. In 2008, Chinese enterprises also put the production of screw vacuum pump into mass production, which has been well applied in chemical and pharmaceutical industries.
