Abstract

The invention discloses a rotary compressor comprising a shell, a motor and a compressing mechanism, wherein the shell comprises a lower shell assembly; the compressing mechanism comprises a main bearing, an air cylinder and an auxiliary bearing assembly; the auxiliary bearing assembly comprises an auxiliary bearing comprising a hub part and a flange part; when the delivery volume V of a compression chamber is smaller than 13cm<3> / rev, 0.1<=P1 / P2<=1.2; when 13cm<3> / rev<=V<=24cm<3> / rev, 0.1<=P1 / P2<=1.5; when V>24cm<3> / rev, 0.1<=P1 / P2<=2; and P1=H1 / H2, P2=H3 / H4, H1 represents for a vertical distance from the center of the lower surface of the hub part to the lower shell assembly, H3 represents for a vertical distance from the edge of the lower surface of the flange part to the lower shell assembly, and H2 and H4 respectively represent for the heights of the auxiliary bearing assembly and the air cylinder. According to the rotary compressor disclosed by the invention, the quantity of a refrigerant which is stored in an oil pool and is dissolved into refrigerating machine oil can be reduced, the dissolution viscosity of the refrigerating machine oil is increased, and the oil supply and supplied oil quality of the rotary compressor are ensured.

Description

technical field [0001] The invention relates to the field of refrigeration equipment, in particular to a rotary compressor. Background technique [0002] It is pointed out in the related art that part of the refrigerant compressed by the rotary compressor will dissolve into the refrigerating machine oil in its oil pool, which will reduce the dissolved viscosity of the refrigerating machine oil, thereby reducing the lubrication conditions of the moving parts in the rotary compressor, thereby reducing The reliability and working efficiency of the rotary compressor are improved. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, an object of the present invention is to provide a rotary compressor that can reduce the amount of refrigerant dissolved in refrigerating machine oil in its oil pool. [0004] The rotary compressor according to the embodiment of the present invention inc...
