Axial Flow Fan Diagram

The shape of your blades and the direction they travel will define the performance characteristics of your fan.

Axial flow fan diagram.

The axial flow compressors can be of impulse type or reaction type. The blades of compressor are of aerofoil section. Conversion 230 460 volt 29 figure 23. 16 17 b the difference in the shape of axial flow turbines and axial flow compressor is illustrated.

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. Axial fans adhere closely to classical theory and require less know how than centrifugal fans. Wiring schematic for 575 volt three phase axial fan 28 figure 22.

The different blades can be characterized as shown in the capacity diagram below. Mixed flow fans develops higher pressures than axial fans. The blade profile and variation of pressure and velocity in the stage are shown in the fig. Axial flow fans this manual is for installation operation and maintenance of all caldwell axial fans with serial numbers.

The inlet and outlet velocities of the air through the blades will be the same for axial fans and different for centrifugal fans v ᵢ and v ₒ. These permit running at the rotational speeds necessary to produce worthwhile pressure. Axial flow fans have developed rapidly since the second world war due to the creation of a range of high strength aluminium alloys. Conversion 460 230 volt 30.

Fig 3 shows the velocity diagram for the air flowing into the fan inlet and out of it outlet.
