The advantage is a very good summary of the performance of a device. Understanding the advantages of screw vacuum pump can ensure the efficiency of the equipment. After all, knowing that it can be better used in operation, and the effect of using will be very good, of course, without understanding the efficiency will not be so good.
Screw vacuum pump is a kind of suction and exhaust equipment which uses a pair of screw to make synchronous high-speed reverse rotation in the pump shell. It is widely used in pharmaceutical, chemical, semiconductor and other enterprises which require higher clean vacuum.
The two screw rods of screw vacuum pump are corrected by fine dynamic balance, supported by bearings and installed in the pump housing. There is a certain gap between the screw and the screw. Therefore, when the screw vacuum pump works, there is no friction between them, the operation is stable, the noise is low, and the working chamber does not need lubricating oil. Therefore, screw vacuum pump can extract gas containing a large amount of steam and a small amount of dust, which has the advantages of higher limit vacuum, lower power consumption, energy saving and maintenance-free.
Secondly, compared with the oil-sealed mechanical vacuum pump, the condensable substance will not stay in the pump, no oil vapor and oil mist emissions, and is very environmentally friendly. Therefore, the screw vacuum pump is a renewal product of the oil-sealed vacuum pump, and a single screw vacuum pump can continuously discharge the atmosphere directly. The vacuum system can be greatly simplified by pumping from the atmosphere to less than 5Pa.
The working chamber of the screw vacuum pump and the surface of the screw vacuum pump have anti-corrosion coating, which can adapt to harsh working conditions, and after high-precision dynamic balance, it can run at high speed, work smoothly, and the whole body is small.
