Abstract

The invention provides a pump body assembly of a rotor compressor, the rotor compressor and an air conditioner. The pump body assembly of the rotor compressor comprises an air cylinder structure; a piston, which is arranged in the air cylinder structure, a mounting space is formed in the piston, and an opening of the mounting space is formed in the first end face of the piston; a balance block, which is arranged in the mounting space; and a crankshaft, which is connected with the first end face of the piston. According to the technical scheme, the problem that a crankshaft is prone to deflection deformation due to eccentric arrangement of the mass center of the pump body assembly in the prior art is effectively solved.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a pump body assembly of a rotary compressor, a rotary compressor and an air conditioner. Background technique [0002] In recent years, in the industry of rotary compressors, the main development direction of compressor models is miniaturization and high frequency. New product research and development is carried out for covering from small displacement to large displacement, low energy efficiency to high energy efficiency, through Reduce the material cost of the compressor to improve the core competitiveness of air-conditioning products in the domestic and foreign markets. [0003] The pump body structure of the rolling rotor compressor is mainly composed of a cylinder, a rolling piston, a crankshaft, a sliding vane, a spring, and flanges assembled at both ends of the cylinder. For the development of the traditional single-cylinder rolling rotor compressor in the high-speed ...
