Embodiment Construction

[0036] In order to make the technical solution of the present invention clearer, the structure of the pump body and the compressor of the present invention will be further described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the present invention and not to limit the present invention.

[0037] see Figure 2 to Figure 15 ,Such as figure 2 As shown, the pump body structure of an embodiment of the present invention includes a muffler 1, an upper flange 2, a cylinder 3 and a lower flange 4 arranged in sequence along the axis, the flow hole of the cylinder 3 and the exhaust hole of the upper flange 2 21 connected. The muffler 1 in this embodiment includes a sealed raised portion 11 and a skirt 12 surrounding the raised portion 11, and the raised portion 11 is circular, and the raised portion 11 and the skirt 12 are integrated , see Figure 3 to Figure 5 shown. Th...

Abstract

The invention provides a pump body structure. The pump body structure comprises a silencer, an upper flange, an air cylinder and a lower flange which are sequentially arranged along a shaft, wherein a circulating hole of the air cylinder is communicated with a gas vent of the upper flange; the silencer comprises a sealed lug boss and a skirt edge surrounding the periphery of the lug boss; the upper flange partly penetrates through the silencer, so that the silencer sleeves the upper flange, and a muffling cavity is defined by the silencer and the upper flange; an air exhausting groove is formed in the position at which the upper flange is in contact with the skirt edge of the silencer; high-pressure gas inside the muffling cavity is discharged through the air exhausting groove. The invention further relates to a compressor. The pump body structure and the compressor carry out sound absorption and sound insulation through the muffling cavity defined by the silencer and the upper flange, and low and medium frequency noise of the compressor is reduced; besides, high-pressure aerodynamic noise generated by a pump body component can be exhausted through the air exhausting groove formed in the upper flange, so that the high-pressure aerodynamic noise is effectively reduced, and the aerodynamic noise of the compressor is reduced.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a pump body structure and a compressor. Background technique [0002] Compressor noise is one of the main noises of air-conditioning systems, and the effective control of its noise will be a powerful guarantee for the quality of air-conditioning noise. The noise generated by pump body components is an important part of the overall noise of the compressor, which has a great impact on the overall noise of the compressor. [0003] For rotary compressors, the main means to reduce the noise of pump body parts are: by adding a muffler, the upper plane of the muffler is provided with an exhaust port, and part of the high-pressure gas of the compressor is discharged into the upper muffler through the upper flange. After the muffler is silenced, it is discharged into the cavity of the shell through the exhaust hole of the muffler; after a part is discharged into the lower muffler thr...
