Axial flow fan diagram.

Axial flow fans have developed rapidly since the second world war due to the creation of a range of high strength aluminium alloys. Axial fans adhere closely to classical theory and require less know how than centrifugal fans. Axial flow fans this manual is for installation operation and maintenance of all caldwell axial fans with serial numbers. The axial flow compressors can be of impulse type or reaction type.

These permit running at the rotational speeds necessary to produce worthwhile pressure. The different blades can be characterized as shown in the capacity diagram below. 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. 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.

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. Mixed flow fans develops higher pressures than axial fans. Wiring schematic for 575 volt three phase axial fan 28 figure 22.

The blades of compressor are of aerofoil section. Wiring diagram 23 28 af12 751 23 af18 11 24 single phase 230 volt 25. The shape of your blades and the direction they travel will define the performance characteristics of your fan. The flow is axial at entry and exit.
