Abstract
The invention relates to an improved vortex vacuum pump. The pump comprises a pump body and a pedestal fixed on at the bottom of the pump body, wherein a stator and a rotor are arranged in the pump body, the top of the pump body is provided with a gland, the pump body and the gland are fixedly connected through a fixing device, the gland is provided with a suction channel, the stator is a multi-stage stator, the inner side of the multi-stage stator is provided with radial vanes, the rotor is a multi-stage rotor, and the multi-stage rotor is formed by a plurality of layers of single-stage rotors. The improved vortex vacuum pump has the advantages of simple structure, easy processing, simple maintenance, reasonable design of a positioning device, good guidance quality during motion, uniform bearing, less maintenance frequency, service life prolongation, production cost reduction and production efficiency improvement.
Description
Technical field
The present invention relates to a kind of vacuum pump, relate in particular to a kind of improved DRY SCROLL VACUUM PUMP.
Background technique
In recent years, people have easily developed polytype dried pump, are widely used in the every field that semi-conductor industry, analytical instrument and electronics industry equal vacuum are used, existing vacuum pump processing, assembling, positioning requirements precision are high, and processing must be used special plane, and reject rate is high, is unfavorable for batch production, cost is higher, on existing vacuum pump, valve block and spring easily come off, and easily are sucked into to cause the cylinder body wearing and tearing in cylinder, reduce the vacuum pump performance, for addressing the above problem, the spy provides a kind of new technological scheme.
Summary of the invention
The purpose of this invention is to provide a kind of improved DRY SCROLL VACUUM PUMP.
The technical solution used in the present invention is:
A kind of improved DRY SCROLL VACUUM PUMP, comprise the pump housing and the base that is fixed in pump housing bottom, also be provided with stator and rotor in the described pump housing, described pump housing top is provided with gland, and being fixed by positioning device between the described pump housing and gland is connected, and described gland is provided with air intake passage, described stator is multistage stator, described every grade of stator inboard is provided with radial blade, and described rotor is multi-stage rotor, and described multi-stage rotor is formed by multilayer single-stage rotor.
Described positioning device comprises positioning screw, nut, pressing plate and spring, is provided with successively nut, pressing plate and spring on described positioning screw.
Advantage of the present invention is: simple in structure, be easy to processing, easy to maintenance, positioning device reasonable in design, during motion, guidance quality is good, stressed evenly, maintenance frequency is few, has extended working life, reduces production costs, and enhances productivity.
