Axial Flow Fan Working

Axial fan blades work in much the same way as aircraft wings.

Axial flow fan working.

As in most cases the blades are cantilevered and only supported at the end adjacent to the hub fluctuating stresses are more important. This is connected to powerful drive motor and these are assembled in a housing designed for parallel flow of air through the fan.

Features of axial fans. 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 impellers will also be subject to centrifugal forces and thus the various elements will be stressed. The guide vanes change the deflected airflow into axial flow and introduce the gas into the diffuser tube further converting the kinetic energy of the gas into pressure energy axial fan and finally introducing the working line.

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. The flow is axial at entry and exit. 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. 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.
