Abstract

The invention provides a pump body assembly, a fluid machine and heat exchange equipment. The pump body assembly comprises an upper flange, a lower flange, an air cylinder, a roller, a long shaft, and a short shaft, wherein the air cylinder is clamped between the upper flange and the lower flange; the roller can be rotatably arranged in the air cylinder; a first sliding groove is formed in an upper end of the roller and a second sliding groove is formed in a lower end of the roller; a bottom end of the long shaft penetrates through the upper flange and is arranged in the first sliding groove in a sliding manner; the long shaft is eccentric to the air cylinder and an eccentric distance e is fixed; a top end of the short shaft penetrates through the lower flange and is arranged in the second sliding groove in a sliding manner; the short shaft is eccentric to the air cylinder and an eccentric distance e is fixed; the short shaft is eccentric to the long shaft and an eccentric distance 2e is fixed; and a sliding included angle is formed between an extension direction of the first sliding groove and an extension direction of the second sliding groove. According to the pump body assembly disclosed by the invention, the problems of a complicated structure and difficult assembly of the pump body assembly in the prior art can be effectively solved.

Description

technical field [0001] The invention relates to the technical field of pump bodies, in particular to a pump body assembly, fluid machinery and heat exchange equipment. Background technique [0002] In the prior art, the pump body assembly adopts a piston structure, and the positions of the centers of mass of the rotating shaft and the cylinder of the pump body assembly change during movement. The motor drives the crankshaft to output power, and the crankshaft drives the piston to reciprocate in the cylinder to compress the gas or liquid to do work, so as to achieve the purpose of compressing the gas or liquid. [0003] There are many defects in the traditional piston-type pump body assembly: the pump body assembly drives one or more pistons to work through the crank-link mechanism, the structure is complicated and the assembly is difficult. In addition, the crankshaft and the piston are subjected to a large lateral force, and the piston is easy to wear, resulting in a decre...
