Axial Flow Fan Diagram

The blades of compressor are of aerofoil section.

Axial flow fan diagram.

Conversion 230 460 volt 29 figure 23. Wiring schematic for 575 volt three phase axial fan 28 figure 22. Fig 3 shows the velocity diagram for the air flowing into the fan inlet and out of it outlet. The shape of your blades and the direction they travel will define the performance characteristics of your fan.

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. The axial flow compressors can be of impulse type or reaction type. 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 fans this manual is for installation operation and maintenance of all caldwell axial fans with serial numbers.

Axial fans adhere closely to classical theory and require less know how than centrifugal fans. The flow is axial at entry and exit. 16 17 b the difference in the shape of axial flow turbines and axial flow compressor is illustrated. Mixed flow fans develops higher pressures than axial fans.

Conversion 460 230 volt 30. These permit running at the rotational speeds necessary to produce worthwhile pressure. In a mixed flow fan the air flows in both axial and radial direction relative to the shaft. The blade profile and variation of pressure and velocity in the stage are shown in the fig.

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.
