Seat Impeller

The impeller is mainly composed of blades, shaft core, and casing. The blade is the core part, with various shapes including forward, backward, and radial, which directly affect the working characteristics of the impeller. The shaft core provides rotational support to ensure stable rotation, while the casing protects and guides fluid flow. According to the form of the blades, impellers can be divided into three types: open, closed, and semi open. The open impeller structure is simple and suitable for handling fluids containing large particle impurities; The closed impeller forms a closed space, improving the accuracy and efficiency of fluid transportation; The semi open impeller combines the characteristics of both and is suitable for situations that require certain sealing and anti clogging capabilities.

The impeller refers to both the disc with moving blades, which is a component of the impulse turbine rotor, and the general term for the disc and the rotating blades installed on it.
