The core technology and main manufacturers of vortex vacuum pump in the world are concentrated in the United States, Japan and a few developed countries in Europe. The development of dry vortex vacuum pump in China is still in its infancy, and its products mainly rely on imports. This situation is mainly due to technology, product prices and other reasons. In order to change the status quo of product dependence on imports
The working chamber of the vortex vacuum pump is composed of a pair of vortex disk pairs with conjugate profile. A scroll is a scroll like structure with one or several involute spiral grooves on its surface. A static scroll plate and a dynamic scroll plate are staggered and assembled together. The anti rotation mechanism ensures 180 ° phase difference between the dynamic and static scroll plates. Thus, a pair of scroll plate pairs constitute the pumping mechanism of oil-free scroll vacuum pump. The static scroll and the dynamic scroll contact each other in several straight lines (several points on the cross section) to form several pairs of crescent shaped closed cavities. The driving of the dynamic scroll in the crankshaft
Vacuum clean, oil-free and pollution-free has always been the ideal environment for the vacuum industry, and the scroll vacuum pump is a new type of oil-free mechanical pump, which has the advantages of simple power transmission, small gas flow loss, stable operation, compact and simple structure, good sealing performance, low power consumption, low vibration and noise, high reliability, etc.; it is superior to Wx oil-free rotary vane vacuum pump in limiting vacuum degree And so on.
