Axial flow fan diagram.

Axial flow fans this manual is for installation operation and maintenance of all caldwell axial fans with serial numbers. Axial flow fans have developed rapidly since the second world war due to the creation of a range of high strength aluminium alloys. 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.

The blades of compressor are of aerofoil section. These permit running at the rotational speeds necessary to produce worthwhile pressure. The flow is axial at entry and exit. In a mixed flow fan the air flows in both axial and radial direction relative to the shaft.

Fig 3 shows the velocity diagram for the air flowing into the fan inlet and out of it outlet. 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. Conversion 460 230 volt 30. The axial flow compressors can be of impulse type or reaction type.

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 shape of your blades and the direction they travel will define the performance characteristics of your fan. The different blades can be characterized as shown in the capacity diagram below.
