Working Principle 

An oil-free scroll vacuum pump consists of a pump head, motor, base, and other components. The pump head includes dynamic and fixed scroll discs, a crankshaft, seals, a fan, and a pump housing. The scroll discs are composed of a circular plane and one or more involute spiral walls extending from it. The fixed scroll disc and the dynamic scroll disc together form the basic pumping mechanism of the oil-free scroll vacuum pump. During operation, the dynamic and fixed scroll discs do not come into contact but rely on relative motion to form continuously shrinking crescent-shaped compression chambers. Through the cycle of suction, compression, and exhaust, gas is drawn in from the intake port and expelled from the exhaust port, achieving vacuum pumping of the chamber.
