Axial Flow Fan Working

The fan is designed to produce a pressure difference and hence force to cause a flow through the fan factors which determine the performance of the fan include the number and shape of the blades.

Axial flow fan working.

Axial fan blades work in much the same way as aircraft wings. The application and the location of the fan determines the. 7 8 stressing of axial impellers 7 8 1 introduction. An axial fan is a type of fan that causes gas to flow through it in an axial direction parallel to the shaft about which the blades rotate.

Axial flow fan impellers will also be subject to centrifugal forces and thus the various elements will be stressed. All our axial flow fans can be supplied as a standard with 2 to 10 mm casing gauge and a diameter from 250 mm to 2800 mm. The design of an axial flow fan is described by the casing length fan diameter inner dimension casing thickness motor terminal box design and the accessories. As in most cases the blades are cantilevered and only supported at the end adjacent to the hub fluctuating stresses are more important.

The flow is axial at entry and exit. Wtw bill cory in fans and ventilation 2005. The main distinguishing component of the axial fan is the axial impeller with the number of blades ranging from 2 to 20 depending on the design and performance requirements. Features of axial fans.
