Problems solved by technology

[0002] The double-headed screw vacuum pump is a pumping device that uses a pair of screws to perform synchronous high-speed reverse rotation in the pump casing to generate suction and exhaust. The two screws are finely balanced and calibrated, supported by bearings, and installed in the pump casing. In the middle, there is a certain gap between the screw and the screw, so when the pump is working, there is no friction between each other, the operation is stable, the noise is low, the working chamber does not need lubricating oil, the ultimate vacuum is higher, the power consumption is lower, and it is energy-saving. At present, the development of various vacuum pumps is more and more affected by vacuum app

Abstract

The invention discloses a two-start worm vacuum pump. The two-start worm vacuum pump includes a vacuum pump base, wherein the top surface of the vacuum pump base is provided with a base screw; a vacuum pump body is connected with the top surface of the vacuum pump base through bolts; a vacuum pump motor is arranged on the side of the vacuum pump body; an external circuit box is fixedly connected with the side of the vacuum pump motor; the inner cavity of the vacuum pump motor is connected with a coupling in series; a first worm is clamped to the side, away from the vacuum pump motor, of the coupling; a first gear is fixedly connected with the side, away from the coupling, of the first worm; a linkage gear is clamped to the tooth surface of the first gear; and a second gear is clamped to the tooth surface, away from the first gear, of the linkage gear. According to the structure of the two-start worm vacuum pump, the positive rotating teeth and the reverse rotating teeth are welded to one worm so that the gas transportation distance can be shortened by half; the gas backflow is reduced; the gas transfer efficiency is greatly increased; and the work efficiency of the two-start worm vacuum pump is directly improved.
