Dry screw vacuum pump is a suction and exhaust device which uses a pair of screw rods to rotate in the pump shell at high speed and reverse synchronously. The two screw rods are supported by bearing and installed in the pump shell after fine dynamic balance correction. There is a certain gap between the screw and the screw rod. Therefore, when the pump works, there is no friction between the screw rod and the pump runs smoothly. Low noise and no lubricating oil in working chamber.
Therefore, dry screw vacuum pump can remove a large amount of steam and a small amount of dust in the gas occasion, higher limit vacuum, lower power consumption, energy-saving, maintenance-free advantages.
