Problems solved by technology
[0003] However, the existing vane air compressors still have some deficiencies in technology. The existing vane air compressors often bring impurities in the air into the compressor during the air compression process, resulting in Some components in the compressor cannot operate normally, which affects the working efficiency of the compressor
At the same time, the existing vane air compressor will generate a lot of noise during the suction or exhaust process, which seriously affects the entire working environment of the compressor

The invention relates to the technical field of vacuum pressure combination pumps, in particular to a pump body of a vacuum pressure combination pump. The pump body comprises a hollow-circular-tube-shaped pump shell. A front installation base and a back installation base which are communicated with the pump shell are arranged on the front end face and the back end face of the pump shell respectively. A plurality of upper sound absorption strips are arranged at the upper end of the front installation base, the upper end of the back installation base and the upper surface of the pump body, a plurality of lower sound absorption strips are arranged at the lower end of the front installation base, the lower end of the back installation base and the lower surface of the pump body, and the positions of the upper sound absorption strips correspond to the positions of the lower sound absorption strips. The circle centers of circles formed by the multiple upper sound absorption strips and the multiple lower sound absorption strips are first circle centers, the circle center of the pump shell is a second circle center, and the first circle centers are located above the second circle center. An air sucking hole communicated with the front installation base is formed in an opening of the front installation base, and an air outlet hole communicated with the back installation base is formed above the portion behind the air sucking hole. According to the pump body of the vacuum pressure combination pump, noise generated during working is small, and the whole working environment of the air pump is optimized.
Description
technical field [0001] The invention relates to the technical field of a vacuum pressure compound pump, in particular to a vacuum pressure compound pump body. Background technique [0002] An air compressor is a device that converts the mechanical energy of the prime mover into gas pressure energy, and is a pressure generating device for compressing air. There are many types of air compressors, and the vacuum pressure compound pump is one of the most typical models. The vane air compressor is a volumetric compressor. Compared with the piston air compressor, it has no suction, exhaust valve and crankshaft connecting rod structure. Therefore, the vane air compressor has a higher speed and can be compared with the original The motor is directly connected, and the work is relatively quiet. [0003] However, the existing vane air compressors still have some deficiencies in technology. The existing vane air compressors often bring impurities in the air into the compressor during...
