1. Cylinder: As the outer shell structure, it withstands steam pressure and forms the steam flow channel.
2. Rotor: Includes the impeller, moving blades, and main shaft; it is the main rotating component that converts the kinetic energy of steam into mechanical rotational kinetic energy.
3. Baffle: A key stationary component that mounts the stationary blades and supports the rotor.
4. Nozzle: An important component that converts steam pressure energy into kinetic energy.
5. Bearing: Includes support bearings and thrust bearings, ensuring stable rotor rotation.
6. Steam Seal: A sealing device that prevents steam leakage and air ingress.
7. Coupling: A power transmission component that connects the rotor to other machinery (such as a generator).
