Abstract

Disclosed are a fluid machinery, a heat exchange device, and a method for operating a fluid machinery. The fluid machinery comprises: an upper flange (50); a lower flange (60); a cylinder (20), the cylinder (20) being clamped between the upper flange (50) and the lower flange (60); a rotary shaft (10), an axis of the rotary shaft (10) and an axis of the cylinder (20) being eccentrically arranged with eccentric distance being fixed, and the rotary shaft (10) passing through the upper flange (50) and the cylinder (20) in sequence; and a piston assembly (30), the piston assembly (30) being provided with a variable volume cavity (31). The piston assembly (30) is pivotally arranged in the cylinder (20), and the rotary shaft (10) is connected in a driving manner to the piston assembly (30) to change the volume of the variable volume cavity (31). Since the eccentric distance between the rotary shaft (10) and the cylinder (20) is fixed, the rotary shaft (10) and the cylinder (20) rotate around the respective axis during movement, and the position of the centre of mass is unchanged so as to enable the piston assembly (30) to rotate stably and continuously when the piston assembly moves in the cylinder (20), thereby effectively relieving the vibration of the fluid machinery, guaranteeing that the volume of the variable volume cavity (31) is changed regularly, reducing a clearance volume so as to improve the stability of the operation of the fluid machinery, and accordingly improving the working reliability of the heat exchange device.

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...
