Steel casting impeller design

The velocity achieved by the Impeller transfers into pressure when the outward movement of the fluid is confined by the pump casing. Impellers are usually short cylinders with an open inlet (called an eye) to accept incoming fluid, vanes to push the fluid radially, and a splined, keyed, or threaded bore to accept a drive-shaft.

Shape classification

Centrifugal Impeller

The shape of the blade centrifugal fan impeller has several single plate, arc type and wing type etc.. Airfoil blade has good aerodynamic characteristics, high efficiency, good strength and stiffness. The disadvantage is that the manufacturing process is complex, and when the transmission of high dust concentration of the gas, the blade is easy to wear, blade wear, the impurities into the blade, so that the impeller lost balance and vibration. The flat straight blade is simple, but the flow characteristics are poor, and the efficiency is quite close to the efficiency of the other working conditions when the flat curve is compared with the airfoil blade, and the efficiency is lower than the highest efficiency point.

Forward impeller

The front impeller generally adopts circular arc blade, and the rear direction impeller, the large fan adopts the airfoil blade, and the wind turbine of the coal fired boiler with low dust removal efficiency can adopt the circular arc type or the flat plate type blade. The centrifugal fan with flat blade is more.

(a) flat blade; 

(b) arc narrow blade; 

(c) arc blade; 

(d) wing blade; 

(e) flat curve back to blade
