Abstract

A fluid machinery, a heat exchange equipment, and an operating method for fluid machinery. The fluid machinery includes: an upper flange (50); a lower flange (60); a cylinder (20), the cylinder (20) being sandwiched between the upper flange (50) and the lower flange (60); a rotating shaft (10), the axis of the rotating shaft (10) being eccentric to the axis of the cylinder (20) and at a fixed eccentric distance, and the rotating shaft (10) sequentially penetrating through the upper flange (50) and the cylinder (20); and a piston component (30), the piston component (30) being provided with a variable volume cavity (31), the piston component (30) being pivotally provided in the cylinder (20), and the rotating shaft (10) being drivingly connected with the piston component (30) to change the volume of the variable volume cavity (31). Because the eccentric distance between the rotating shaft (10) and the cylinder (20) is fixed, the rotating shaft (10) and the cylinder (20) rotate around the respective axes thereof during motion, and the position of the center of mass remains unchanged, so that the piston component is allowed to rotate stably and continuously when moving in the cylinder (20); and vibration of the fluid machinery is effectively mitigated, a regular pattern for changes in the volume of the variable volume cavity is ensured, and clearance volume is reduced, thereby increasing the operational stability of the fluid machinery, and increasing the working reliability of heat exchange equipment.

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...
