摘要（英）：

The utility model relates to a cooling structure of a medium-pressure rotor and aims to solve the problem that service life and safety of a steam turbine are affected by high-temperature creep of the medium-pressure rotor of the steam turbine at high temperatures. The cooling structure of the medium-pressure rotor consists of a moving blade intermediate body, a first-stage stationary blade diaphragm, radial glands, a moving blade root, a rotor impeller, a blade root cooling groove, a cooling steam inlet, a shaft seal, a diaphragm gland, and a second-stage stationary blade diaphragm, wherein the radial glands are arranged between the moving blade intermediate body and the first-stage stationary blade diaphragm and between the moving blade intermediate body and the second-stage stationary blade diaphragm, a blade root groove is formed between the moving blade root and the rotor impeller, the shaft seal is arranged between the cooling steam inlet and the diaphragm gland, and the diaphragm gland is arranged at the bottom of the second-stage stationary blade diaphragm. The cooling structure is mainly used for cooling the medium-pressure rotor.
