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.
The shape of the blade centrifugal fan impellerhas several single plate, arc type and wing type etc.. Airfoil blade has goodaerodynamic characteristics, high efficiency, good strength and stiffness. Thedisadvantage is that the manufacturing process is complex, and when thetransmission 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 balanceand vibration. The flat straight blade is simple, but the flow characteristicsare poor, and the efficiency is quite close to the efficiency of the otherworking conditions when the flat curve is compared with the airfoil blade, andthe efficiency is lower than the highest efficiency point.
The front impeller generally adoptscircular arc blade, and the rear direction impeller, the large fan adopts theairfoil blade, and the wind turbine of the coal fired boiler with low dustremoval efficiency can adopt the circular arc type or the flat plate typeblade. The centrifugal fan with flat blade is more.
