Title:
FLUID MACHINERY, HEAT EXCHANGING APPARATUS, AND OPERATING METHOD FOR FLUID MACHINERY
Document Type and Number:
WIPO Patent Application WO/2017/024863
Kind Code:
A1
Abstract:
A fluid machinery, a heat exchanging apparatus, and an operating method for the fluid machinery. The fluid machinery comprises: an upper flange (50); a lower flange (60); a cylinder (20), where the cylinder (20) is sandwiched between the upper flange (50) and the lower flange (60); a rotating shaft (10), where the axis of the rotating shaft (10) is arranged eccentric to the axis of the cylinder (20) and at a fixed eccentric distance, and the rotating shaft (10) runs sequentially through the upper flange (50) and the cylinder (20); and a piston component (30), where the piston component (30) is provided with a variable volume cavity (31), the piston component (30) is pivotally arranged within the cylinder (20), and the rotating shaft (10) is actuatedly connected to 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 while in motion, and the position of the center of mass remains unchanged, the piston component is allowed to rotate stably and continuously when moving within the cylinder (20); this effectively mitigates vibration of the fluid machinery, ensures a regular pattern for changes in the volume of the variable volume cavity, and reduces clearance volume, thus increasing the operational stability of the fluid machinery, and thereby increasing the operational reliability of the heat exchanging apparatus.
