[0002] Impeller refers to the wheel disk with moving blades, which is a component of the impulse steam turbine rotor. It can also refer to the general term for the wheel disk and the rotating blades installed on it. Impellers are commonly cast or welded, and the material used for processing needs to be determined according to the specific working environment and purpose. Impeller casting is an advanced manufacturing technology that combines the advantages of precision casting and machining. Precision casting uses advanced mold technology to ensure that the shape and size of the impeller meet the design requirements, and can produce impellers with complex internal structures and fine appearance.
