Problems solved by technology
The traditional noise reduction of the compression mechanism is mainly through setting a resonance chamber at the discharge cutout or setting an expansion muffler behind the exhaust port of the bearing. However, these noise reduction structures have more or less influence on the performance of the rotary compressor. and limited noise reduction

The invention discloses a rotary compressor. The rotary compressor comprises a compression mechanism, mufflers and partition plates, wherein the compression mechanism comprises an air cylinder and two bearings, the two bearings are respectively arranged at the two axial ends of the air cylinder, a compression chamber is defined between the two bearings and the air cylinder, and an air exhaust opening communicated with the compression chamber is formed in at least one of the two bearings; the mufflers are arranged at one side, far away from the air cylinder, of at least one of the two bearings; the partition plates are arranged between the mufflers and the corresponding bearings, first muffling cavities communicated with the air exhaust opening are defined between the partition plates and the mufflers, at least one second muffling cavity is defined between the partition plates and the corresponding bearings, a plurality of micropores are formed in each partition plate, the second muffling cavities are communicated with the first muffling cavities through the micropores, and the area of each micropore is smaller than or equal to pi mm<2>. According to the rotary compressor disclosed by the invention, muffling can be realized, and the influence on the performance of the rotary compressor is low.
Description
technical field [0001] The invention relates to the technical field of compressor manufacturing, in particular to a rotary compressor. Background technique [0002] It is pointed out in the related art that the high-pressure gas refrigerant is discharged from the exhaust port of the bearing to form a strong pressure sound wave, and part of the sound wave impacts into the muffler installed on the bearing, and consumes part of the energy due to the change of the cross section, and the other part is in the form of pressure wave Spread with the flow of refrigerant. The traditional compression mechanism noise reduction is mainly through setting a resonance chamber at the discharge cutout or setting an expansion muffler behind the exhaust port of the bearing. However, these noise reduction structures have more or less influence on the performance of the rotary compressor. And the noise reduction ability is limited. Contents of the invention [0003] The present invention aims ...
