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 have been replaced. A large number of oil-free vacuum systems have been cleaned. Vacuum system instead.
Dry screw vacuum pump are widely used in electronics, nuclear power, chemical industry, medicine, food industry and other fields. In the semiconductor industry for the production of chips, LCD manufacturing, etching, production of PLASMA CVD process. It is used in nuclear industry for nuclear reactor and vacuum acquisition in nuclear industry; in chemical industry for vacuum distillation and solvent extraction for efficient solvent recovery; in fatty acid production for eliminating water pollution and removing blockages in ejectors; in pharmaceutical industry for the recovery of pharmaceutical liquids and pharmaceutical intermediates to provide clean and aseptic conditions for the production of artificial organs. Recycled gas disinfectant; used in the food industry for perfume, flavor concentration, food packaging and other applications are very wide.
Although the dry screw vacuum pump has so many advantages, however, because the dry screw vacuum pump is currently used by some domestic companies are imported from abroad, the price is very expensive, each screw pump costs 30,000 to 400,000 yuan, so the screw type vacuum pump is not widely used in China. The main reason for this phenomenon is that the rotor profile of the screw pump is more complex and difficult to process, so special cutting tools are needed to process on special machine tools. In addition, the screw type dry vacuum pump body processing accuracy also has higher requirements, and the domestic processing level is still difficult to reach this level.
1. high reliability. The dry screw vacuum pump has fewer components and no wearing parts, so it has reliable operation and long service life.
2. easy to operate and maintain.
3. power balance is good. The dry screw vacuum pump has no unbalanced inertia force, and the machine can run smoothly and steadily.
4. strong adaptability. dry screw vacuum pump has the characteristics of forced gas transmission, can maintain a high pumping speed in a wide range of pressure, the exhaust volume is almost independent of the exhaust pressure.
5., lose much. Because there is a small gap between the tooth surfaces of the screw dry vacuum pump rotor, it can remove many kinds of gases, such as corrosive, toxic, containing dust, condensable steam and so on.
