Axial Flow Fan Working

Features of axial fans.

Axial flow fan working.

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 application and the location of the fan determines the. This is connected to powerful drive motor and these are assembled in a housing designed for parallel flow of air through the fan. 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.

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.

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.

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. 7 8 stressing of axial impellers 7 8 1 introduction. 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. Axial fan blades work in much the same way as aircraft wings.
