Abstract

The invention relates to the technical field of steam turbine moving blade equipment, in particular to a moving blade design method, a moving blade and a steam turbine for driving an air separation compressor. The moving blade design method comprises the following steps that a moving blade is designed to comprise a blade root, a blade body and a shroud ring, and the blade body and the blade root serve as a base part; the wheel disc assembly is designed to comprise a wheel disc and a plurality of moving blades surrounding the wheel disc; keeping the basic part of the wheel disc assembly unchanged, continuously adjusting the parameters of the shroud ring, and solving the resonance rotating speed avoiding interval of the wheel disc assembly for avoiding the triple key points; and determining the moving blade design result as the moving blade corresponding to the wheel disc assembly until the target operation interval falls into the resonance rotating speed avoiding interval of the wheel disc assembly. The moving blade is designed according to a moving blade design method. A steam turbine driving the air separation compressor includes a rotor blade. The invention relates to a moving blade design method, a moving blade and a steam turbine for driving an air separation compressor. A shaped blade which only operates in a specific operation interval is improved into a universal blade which meets various operation intervals.

Description

technical field [0001] The present application relates to the technical field of steam turbine moving blade equipment, in particular to a design method of a moving blade, a moving blade and a steam turbine driving an air separation compressor. Background technique [0002] The full-circle self-locking damping blade has good performance in reducing resonance vibration stress. The basic structure of the full-circle self-locking damping blade is a single-piece structure with a shroud on the blade top. [0003] However, at present, the whole circle of self-locking damping blades is usually re-designed according to the needs of each application, and the design cost is high and the design cycle is long, resulting in high production costs for the manufacturer's moving blades. Contents of the invention [0004] The purpose of this application is to provide a method for designing a moving blade, a moving blade and a steam turbine driving an air separation compressor, so as to solve...
