The invention relates to a complex impeller power generation system rotor which structurally comprises a nut, a shaft sleeve, a motor shaft, a main shaft and a complex impeller. According to structural size parameters of a turbine, a gas compressor and a motor of the closed Brayton cycle power generation system, machining of the nut, the shaft sleeve, the motor shaft, the main shaft and the complex impeller is completed on the basis that the size parameters and assembly torque of rotor components are determined. A complete closed Brayton cycle thermoelectric conversion system rotor structure is formed by sequentially completing assembly of the motor shaft, assembly of the main shaft and the motor shaft, assembly of the shaft sleeve, the motor shaft and the main shaft, and assembly of the main shaft, the complex impeller and the nut. The rotor structure is less in components, not only facilitates assembly of the closed cycle power generation system rotor, but also benefits improvement of the rigidity and strength of the rotor, and the working reliability of the closed cycle power generation system is improved.
Description
technical field [0001] The invention belongs to the technical field of structural design of a closed Brayton cycle thermoelectric conversion system, and in particular relates to a rotor structure and technology of a composite impeller power generation system. Background technique [0002] As a new form of thermoelectric conversion, the closed cycle thermoelectric conversion system can convert thermal energy to mechanical work through thermal processes such as heat absorption, expansion work, heat release and compression with the help of a certain gas working fluid in a closed environment, and The mechanical work is further converted into electrical energy by a generator. During the working process of the closed Brayton cycle thermoelectric conversion system, there is only energy exchange with the outside world, but no working fluid exchange. A typical closed Brayton cycle thermoelectric conversion system is mainly composed of turbines, compressors, generators, regenerators,...
