Embodiment Construction

[0012] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0013] Such as figure 1 As shown, a novel vacuum pump of the present invention includes a straight cylindrical pump body 2, two ends of the pump body are provided with connecting flanges, and the connecting flanges are fastened by screws. The two ends of the pump body 2 are respectively provided with an air inlet and an air outlet. A forward-rotating high-speed motor 1 and a reverse-rotating high-speed motor 3 are respectively installed at both ends of the pump body 2. The high-speed motor is fixed in the pump body through a bracket. The rotating shafts of the two high-speed motors are opposite to each other, and the rotating directions are opposite. Three impellers 4 are respectively installed on the rotating shafts of the two high-speed motors. The number of the impellers can be adjusted according to the different needs of the pressure. Guide vanes 5 are a...

Abstract

The invention discloses a novel vacuum pump which comprises a straight-barrel-shaped pump body. An air inlet and an air outlet are formed in the two ends of the pump body respectively. Two high-speed motors are arranged at the two ends in the pump body respectively. Rotary shafts of the two high-speed motors are opposite, and the two high-speed motors are opposite in the rotating direction. The rotary shafts of the two high-speed motors are each provided with two or more impellers. Guide vanes are arranged between the adjacent impellers. A support used for supporting the rotary shafts of the high-speed motors is arranged in the center of the pump body. According to the novel vacuum pump and a novel multi-stage vacuum pump, the structure is simple and compact, the size is small, no other matched devices are needed, ultimate vacuum is higher, consumed power is lower, and noise is lower.

Description

technical field [0001] The invention relates to a vacuum pump. Background technique [0002] Vacuum pumps include dry screw vacuum pumps, water ring pumps, reciprocating pumps, slide valve pumps, rotary vane pumps, Roots pumps and diffusion pumps. At present, the most widely used in the industry are water ring vacuum pumps and rotary vane vacuum pumps. This type of pump has the disadvantages of low vacuum degree, loud working noise, and high energy consumption. Generally, one needs to be opened as a spare, which virtually increases equipment investment and operating costs. In recent years, with the sustained and high-speed development of my country's economy, the downstream application industries related to vacuum pumps have maintained a rapid growth momentum. Designing a new type of vacuum pump with simple structure, high vacuum, low energy consumption, and low noise will help achieve sustained, stable and rapid economic development. is of great significance.
