Dry screw vacuum pump is a technological product with very high technical content, which is mainly used in the vacuum process with high purity. The vacuum degree is very high, and it can adapt to the harsh working conditions. It has the ability to extract condensate and particulate gas, especially suitable for electronics, chemical industry, biomedicine and other fields.

Dry screw vacuum pump, is the use of a pair of screw, made in the pump shell synchronous high-speed reverse rotation of the effects of the suction and exhaust and suction device, two screw fine dynamic balancing correction, and is supported by bearings, is installed in the pump shell, screw and has a certain gap between the screw, so the pump is working, no friction between each other, smooth running, low noise, working cavity without lubricating oil, therefore, dry screw pump can pump in addition to containing a large amount of water vapor and a small amount of dust gas occasions, limiting vacuum is higher, lower power consumption, energy saving, maintenance free, etc. It is the replacement product of oil seal vacuum pump.

The core part of screw vacuum pump, screw rotor, is designed and solved by three-dimensional curved surface mathematical model. The solid part of the model is processed on five-axis CNC equipment, with high precision, reliable quality and stable performance, which ensures the product's long-term trouble-free operation.

This product innovation, product quality and price has the very strong market competitiveness, can replace imported products widely in market demand, will be in the chemical industry, metallurgy, electronics, petroleum, aerospace, tools, paper, packaging, food, medicine, medical apparatus and instruments, and information engineering, biological engineering, microelectronics and so on more than 100 fully replace the low technical content in the field of vacuum equipment.
