Novel vacuum pump

Abstract

The invention discloses a novel vacuum pump, comprising a main body, the main body comprising a vacuum pump housing and a rotor, a mounting hole is provided on the side end surface of the vacuum pump housing, a front end cover is provided on one side of the vacuum pump housing, and the front end A first sealing ring and a second sealing ring are arranged between the cover and the vacuum pump housing, the first sealing ring is located on one side of the second sealing ring, and the first sealing ring and the second sealing ring are A sleeve is arranged between the rings, and the beneficial effects achieved by the invention are: the gas transmission path inside the vacuum pump is short, and it is not easy to produce reactant precipitation; the rotor is provided with a male rotor and a female rotor, and the male rotor and the female rotor are meshed with each other to achieve the airtight effect. , the structure is simple, the failure rate is low, and the maintenance is convenient; by setting the first sealing ring and the second sealing ring, the air tightness inside the vacuum pump casing is good, and the air extraction effect is better; The high temperature generated during the rotor rotation is quickly reduced, and the safety of use is improved.

Description

technical field [0001] The invention relates to a novel vacuum pump, which belongs to the technical field of vacuum pumps. Background technique [0002] With the development of vacuum applications, many types of vacuum pumps have been developed, and their pumping speeds range from a few tenths of a liter per second to hundreds of thousands and millions of liters per second. As vacuum technology has wider and wider requirements for its application pressure range in the field of production and scientific research, most of them need to be composed of several vacuum pumps to pump together to meet the requirements of the production and scientific research process. The range of working pressure involved in the application department is very wide, so any type of vacuum pump cannot be completely suitable for all working pressure ranges, and only different types of vacuum pumps can be used according to different working pressure ranges and different working requirements. . For the ...

Problems solved by technology

When the traditional vacuum pump is used, the exhaust path is long, the reactant precipitates more, and the airtightness of the vacuum pump is not good. At the same time, the traditional vacuum pump is prone to generate a lot of heat inside the vacuum pump. Once it is not operated properly, there is a big safety hazard. , therefore, in order to solve the above problems, the present invention proposes a new vacuum pump
