Swing arm rotation type compressor

Abstract

The invention discloses a swing arm rotation type compressor which comprises a housing, a main shaft and an air guide pipe for communicating a two-stage compression chamber with an air inlet cavity or an air outlet cavity of a rotary valve, wherein the upper end surface of the housing is covered with an upper bearing sealing seat with a gland; an eccentric shaft section is formed in the middle of the main shaft; the inner circle of a rotary sleeve arranged in an inner cavity of the housing is connected with the eccentric shaft section of the main shaft through a sleeve bearing; the main shaft on the upper side and the lower side of the rotary sleeve is connected with the upper bearing seat and the housing through a pair of upper and lower rolling bearings; the rotary valve with the air inlet cavity and the air outlet cavity is arranged on the main shaft on the outer side of the upper bearing; the rotary valve is axially fixed by a locking nut through a valve plate and a gasket; an air inlet connector communicated with the air inlet cavity of the rotary valve and an air outlet connector communicated with the air outlet cavity of the rotary valve are arranged on the outer wall of the upper bearing seat; multiple sets of swing arm mechanisms contacted with the outer circle of the rotary sleeve are arranged along the inner circumferential direction of the housing; and the swing arm mechanisms, the housing, the rotary sleeve and the upper bearing seat form the two-stage compression chamber. According to the swing arm rotation type compressor, the functions of air suction, compression, air discharge and residual air expansion can be effectively achieved, multiple times of sequential compression operation can be finished by rotating the main shaft for a circle, the two-stage compression operation can be performed in each compression process, and the compressor is very small in frictional loss between moving parts, energy-saving, efficient and wide in application range.

Description

technical field [0001] The present invention relates to a rotary gas compression fluid conveying machine, in particular to a rotating sleeve driven eccentrically arranged and a swing arm arranged in a circle through the rotation of the main shaft to realize the change of the working volume and complete the gyration in the processes of suction, compression and exhaust. compression machinery. Background technique [0002] Fluid conveying machinery is an indispensable equipment in the fields of industry and life, among which rotary gas compressors are mainly used in the field of refrigeration, such as household portable, window type, split type air conditioners and humidifiers, household refrigerators, food refrigeration, car air conditioners Systems, heat pumps, etc.; automotive air conditioning systems; industrial general air compression; other special gas (oxygen, nitrogen, ethylene, etc.) compression and other common equipment. Today, the most typical eccentric rotary comp...
