Abstract

The invention belongs to the technical field of compressors, and specifically discloses a low-wear air conditioner compressor. The low-wear air conditioner compressor comprises an air cylinder, a drive module, a compression module and a regulating module, wherein the air cylinder is mounted at one side of the drive module; the air cylinder is used for performing gas suction, compression and gas exhaust; the compression module is mounted in the air cylinder in a matched mode, and comprises a first eccentric shaft, an eccentric block, a first bevel gear, a second eccentric shaft, a second bevelgear, rotors, a slide plate and a first pin roller; the regulating module is mounted between the drive module and the air cylinder in a matched mode for regulating spacing of the rotors inside the compression module and correcting influences, on the machine, of wear of the rotors. According to the low-wear air conditioner compressor disclosed by the invention, the rotary rollers are not in contactwith the side wall of the air cylinder, so that the air cylinder does not need to replace, and therefore, maintenance cost is reduced, and the service life of the machine is prolonged; the two rotaryrollers are arranged, so that gas compression is realized; and moreover, the regulating module is arranged for compensating wear of the rotary rollers, so that the comprehensive service life of the machine is prolonged.

Description

technical field [0001] The invention belongs to the technical field of compressors, in particular to a low-wear air-conditioning compressor. Background technique [0002] A compressor is a driven fluid machine that elevates low-pressure gas to high-pressure gas, and is the heart of the refrigeration system. It inhales low-temperature and low-pressure refrigerant gas from the suction pipe, drives the piston to compress it through the operation of the motor, and discharges high-temperature and high-pressure refrigerant gas to the exhaust pipe to provide power for the refrigeration cycle. In this way, the refrigeration cycle of compression→condensation (heat release)→expansion→evaporation (heat absorption) is realized. [0003] Rolling rotor compressors usually include a rotor and a slide plate in structure. In terms of working principle, the slide plate is mainly attached to the surface of the rotor, and a working volume is formed between the outer surface of the rotor, the i...
