Dry screw vacuum pump, it is the wisdom of the weihai vacuum technology co., LTD., independent research and development production, which USES 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, between screw and screw has a certain gap, 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.
◇ His profile:
Dry screw vacuum pump is a technological product with very high technical content. It is mainly used in the vacuum process with high purity. The vacuum degree is very high, and it can adapt to harsh working conditions.
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 the five-coordinate linkage NUMERICAL control 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.
◇ Performance characteristics:
1. There is no medium in the working chamber, so a clean vacuum can be obtained.
2. The surface of the working cavity and screw rotor is covered with anti-corrosion coating, which can adapt to bad working conditions.
3, the gas in the pump without compression, suitable to extract condensable gas.
4, a single pump can be pumped from the atmosphere to 1Pa, the vacuum system can be greatly simplified.
5. Water temperature has little influence on vacuum, saving water up to 90% or even no water consumption.
6, no oil consumption, no drip leakage.
7. No friction between rotating parts, high-speed operation, small volume of the whole machine
8. Simple structure and easy maintenance.
9, the pumped gas directly discharged from the pump body, no pollution of water, no environmental pressure, gas recovery is more convenient.
10, can be combined with roots pump, molecular pump oil - free unit.
