What are the internal and external characteristics of industrial steam turbines? What is the relationship between the two?
Internal characteristics: refer to the relationships of variation among parameters such as power, flow rate, enthalpy drop, pressure, reaction degree, and internal efficiency. External characteristics: refer to the relationship between power, torque, and speed. Relationship between the two: GHsŋi= Ni=2πnM, where G represents flow rate ； Hs represents the enthalpy drop ； ηi represents the internal efficiency ； Ni represents power ； n represents the rotational speed ； M represents torque ； The relationship of mutual transformation between the two sides of the first equal sign belongs to an issue of internal properties. The relationship of mutual variation on both sides of the second equal sign belongs to the issue of external characteristics.
