Abstract

The invention provides a pump body assembly, a compressor and a heat exchange system. The pump body assembly comprises a roller with a sliding piece groove, a sliding piece, a cylinder and a flange. The sliding piece is arranged at the position of the sliding piece groove in a slidable manner and comprises a first limiting structure. The roller is arranged in the cylinder in a rotatable manner. A second limiting structure is arranged on the surface, facing the roller, of the flange. The first limiting structure and the second limiting structure are used in cooperation so that when the pump body assembly is at the gas suction stage, a gap exists between the head portion of the sliding piece and the inner wall of the cylinder. The pump body assembly, the compressor and the heat exchange system effectively solve the problem that because at the gas suction stage of a pump body assembly, a compressor and a heat exchange system in the prior art, the head portion of the sliding piece makes contact with the cylinder, friction power consumption is generated.

Description

technical field [0001] The invention relates to the technical field of heat exchange, in particular to a pump body assembly, a compressor and a heat exchange system. Background technique [0002] Compared with other types of compressors, the vane compressor has the advantages of simple parts, no eccentric structure, stable torque and small vibration, but at the same time, the vane compressor also has a disadvantage that affects its energy efficiency, that is, the power consumption of the vane head is too big. The sliding vane compressor pushes the vane out of the vane groove through centrifugal force or back pressure of the vane and forms a seal against the inner wall of the cylinder. Due to the large rotation radius of the vane head, the linear velocity is relatively high during operation, causing the vane head to The friction power consumption generated when the head contacts with the cylinder is very large, which is the main source of mechanical power consumption of the ...
