Abstract

The invention provides a fluid machine, heat exchange equipment and a running method of the fluid machine. The fluid machine comprises an upper flange, a lower flange, a cylinder arranged between the upper flange and the lower flange in a sandwiched manner, a rotating shaft and a piston assembly, wherein the axis of the rotating shaft and the axis of the cylinder are eccentrically arranged and the eccentric distance is fixed, and the rotating shaft sequentially penetrates the upper flange, the cylinder and the lower flange; and the piston assembly has a variable-volume cavity and is arranged in the cylinder in a pivotal manner, and the rotating shaft is connected with the piston assembly in a driving manner to change to the volume of the variable-volume cavity. Because the eccentric distance between the rotating shaft and the cylinder is fixed, the rotating shaft and the cylinder rotate around the axis of the rotating shaft and the axis of the cylinder correspondingly, the mass center position does not change, thus, when the piston assembly moves in the cylinder, the piston assembly can stably and continuously rotate, vibration of the fluid machine is effectively relieved, it is guaranteed that the volume change of the variable-volume cavity has a rule, the clearance volume is reduced, and therefore the running stability of the fluid machine is improved, and the working reliability of the heat exchange equipment is improved.

Description

technical field [0001] The invention relates to the technical field of heat exchange systems, in particular to a fluid machine, heat exchange equipment and an operating method of the fluid machine. Background technique [0002] Fluid machines in the prior art include compressors, expanders, and the like. Take compressors as an example. [0003] In the prior art, the positions of the centers of mass of the rotating shaft and the cylinder of the piston compressor in the prior art 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. [0004] There are many defects in the traditional piston compressor: due to the existence of the suction valve plate and the exhaust valve plate, the resistance of suction and exhaust increases, and the noise of suction and exhaust increases; the lateral fo...
