Abstract

The invention provides a flange structure, a pump body assembly and a fluid machine. The side of the flange structure facing the cylinder liner is provided with a sound-absorbing groove, and the sound-absorbing groove extends along the circumferential direction of the flange structure. The structure is located on the end face of the flange structure and communicates with the bottom of the sound-absorbing groove. The invention can solve the problem that the flange structure in the prior art does not have the sound-absorbing function.

Description

technical field [0001] The invention relates to the related technical field of rotary cylinder compressors, in particular to a flange structure, a pump body assembly and a fluid machine. Background technique [0002] Taking the rotary cylinder compressor as an example, in order to achieve the effect of reducing noise in the pump body components of the existing compressor, an additional muffler is usually arranged outside the upper flange, and the upper flange only provides an exhaust hole to ensure The gas in the cylinder can smoothly flow out through the upper flange, so as to be muffled in the muffler. [0003] The structure of the pump body assembly with such a structure is relatively complex, and the function of the upper flange is single, and the function of noise reduction cannot be realized. [0004] It can be seen from the above that the flange structure of the existing rotary cylinder compressor does not have the function of silencing during operation. SUMMARY OF...
