Steam Turbine Rotor Shaft For Steam Turbine Generator

A steam turbine consists of a rotor resting on bearings and enclosed in a cylindrical casing. The rotor is turned by steam impinging against attached vanes or blades on which it exerts a force in the tangential direction. Thus a steam turbine could be viewed as a complex series of windmill-like arrangements, all assembled on the same shaft. Because of its ability to develop tremendous power within a comparatively small space, the steam turbine has superseded all other prime movers, except hydraulic turbines, for generating large amounts of electricity and for providing propulsive power for large, high-speed ships。 The rotor shaft is a central component of the electric motor. The rotor shaft is the carrier shaft for the laminated core of the rotor and thus transmits the electrically induced torque via a corresponding positive connection in the transmission.The turbine shaft connects the turbine to the generator, turning at the same speed as the turbine. It is essentially an item that is used in machine designed for producing continuous power. The system it is used in basically extracts energy from a fluid flow and then converts it into a usable form or medium.Rotor shafts are also used in many large and traditional sectors of engineering, such as power generation and mining. They are key components in many power generation plants and are often of huge size and power.The main material grades for tubine rotor shafts we produced before are :
