Turbine Wheel VS Impeller, is that the same thing?
Although turbine wheels and impellers are sometimes used interchangeably in everyday contexts, there is a clear distinction between their meanings and uses in technical and industrial applications. A turbine wheel usually refers to a fan in the engine of a car or airplane that uses exhaust gas to blow fuel steam into the engine to improve the engine’s performance. The impeller is composed of a wheel, wheel cover and blade and other parts of the components, the fluid in the impeller blade with the impeller for high-speed rotation, the gas by the role of rotating centrifugal force, as well as the diffuser flow in the impeller, so that it through the […]
