Abstract

The invention provides a pump body assembly, a fluid machine and heat exchange equipment. The pump body assembly comprises an air cylinder sleeve, an air cylinder and a piston, the air cylinder is rotationally arranged in the air cylinder sleeve, and the piston is slidably arranged in the air cylinder; the pump body assembly further comprises a rotary shaft including a cooperation section, the cooperation section is arranged in the piston in a penetrating mode to drive the piston to move, the outer surface of the cooperation section is provided with two horizontally-arranged first cooperationplanes, and the first cooperation planes make contact with the piston so that the rotary shaft can drive the piston to move; and the rotary shaft is provided with an axial oil passing hole, the firstcooperation planes are provided with first oil grooves, the first oil grooves communicate with the axial oil passing hole, and the extending direction of the first oil grooves is perpendicular to theextending direction of the rotary shaft. According to the pump body assembly, the fluid machine and the heat exchange equipment, the problem that in the prior art, the jamming phenomenon is prone to occurring to a piston and a rotary shaft of a rotary cylinder compressor, and thus, normal operation of the rotary cylinder compressor is influenced is effectively solved.

Description

technical field [0001] The invention relates to the technical field of pump body components, in particular to a pump body component, fluid machinery and heat exchange equipment. Background technique [0002] At present, the rotary cylinder piston compressor is a compressor with a new structure, which essentially adopts a cross slider structure principle and combines the main structure of the piston compressor with the main structure of the rotary compressor. compressor. The existing rotary cylinder piston compressor includes a rotating shaft, a piston sleeved outside the rotating shaft, and a cylinder sleeved outside the piston. When the rotating shaft rotates, it drives the piston to perform circular motion, and the distance between the piston and the center of the cylinder runs within the range of 0-e. The rotating shaft and the cylinder are assembled eccentrically, and the rotating shaft drives the cylinder to rotate through the piston. Due to the eccentric relationship...
