Abstract

The invention provides a flange assembly, a compressor and an air conditioner. The flange assembly comprises a flange and a first silencer, wherein the flange comprises a disk and a neck which is connected to the disk; the first silencer comprises a cover and a flanging boss which is arranged on the cover, the cover is connected to the disk, the flanging boss sleeves the neck, an overflowing channel is formed between the flanging boss and the neck, the overflowing channel comprises a reducing section, and the overflowing area of the reducing section is gradually reduced in the direction far from the disk. According to the technical scheme, the problem of large pressure fluctuation of a lower cavity of a motor due to large displacement of the compressor in the prior art is effectively solved.

Description

technical field [0001] The invention relates to the field of compressors, in particular to a flange assembly, a compressor and an air conditioner. Background technique [0002] At present, the application of rotary compressors is becoming more and more extensive, the displacement is constantly increasing, the maximum operating frequency is constantly increasing, the amount of high-pressure refrigerant discharged from the compressor cylinder is increasing, and the cavity of the lower cavity of the compressor motor is limited. Due to the intermittent characteristics of compressor exhaust, the pressure pulsation in the lower cavity of the motor increases, especially when the motor is running at high speed, the pressure pulsation is particularly obvious. The rotor of the motor mainly bears the gas force, axial electromagnetic force and gravity caused by the pressure difference between the upper and lower end faces. Among them, the gas force caused by the pressure difference is ...
