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 very high technical content of science and technology products, mainly used in high purity vacuum process, high vacuum degree, can adapt to harsh working conditions, with the ability to extract condensate, containing particulate gas, especially suitable for electronics, chemical and biological medicine and other fields.
The core part of the screw vacuum pump - screw rotor, using three-dimensional curved surface mathematical model design, solution, through the model of the entity in the five-coordinate linkage CNC equipment processing, high accuracy, reliable quality, stable performance, to ensure that the product long time 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 cavity, can get clean vacuum.
2. The surface of the working cavity and the screw rotor has anti-corrosion coating, which can adapt to harsh working conditions.
3, the gas in the pump is not compressed, suitable for the extraction of condensable gas.
4, single pump can be pumped from the atmosphere to 1Pa, vacuum system can be greatly simplified.
5. The water temperature has little effect on the vacuum, saving more than 90% water, and even does not consume water.
6, no oil consumption, no drip leakage.
7. No friction between rotating parts, high speed operation, small size of the whole machine
8, simple structure, easy maintenance.
9, the pumped gas is directly discharged from the pump body, no pollution of water, no environmental pressure, gas recovery is more convenient.
10. It can be combined with Roots pump and molecular pump to form oil-free unit.
