GWSP series Oil freeScroll Vacuum Pump
Construction and Operating Principle
GWSP series oil free scroll vacuum pump is constructed with fixed scrolls, orbiting scroll, main shaft, cooling fans, crank shaft kits, and bracket.
Its’ operating principle is based on two spiral cylinders, one offset and orbiting against the other with an offset of 180°. Thus several crescent-shaped pockets of differing sizes are created. By means of an eccentric drive, the orbiting scroll is made to orbit about the fixed scroll, reducing the volume of the pockets and compressing gases from the outside towards the inside thereby pumping the gases from vacuum chamber.
