Axial Flow Fan Diagram
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 fan diagram. The flow is axial at entry and exit. Wiring diagram 23 28 af12 751 23 af18 11 24 single phase 230 volt 25. The axial flow compressors can be of impulse type or reaction type. The shape of your blades and the direction they travel will define the performance characteristics of your fan.
The blade profile and variation of pressure and velocity in the stage are shown in the fig. Mixed flow fans develops higher pressures than axial fans. Axial flow fans this manual is for installation operation and maintenance of all caldwell axial fans with serial numbers. Conversion 460 230 volt 30.
Axial fans adhere closely to classical theory and require less know how than centrifugal fans. 16 17 b the difference in the shape of axial flow turbines and axial flow compressor is illustrated. The blades of compressor are of aerofoil section. The different blades can be characterized as shown in the capacity diagram below.
Conversion 230 460 volt 29 figure 23. These permit running at the rotational speeds necessary to produce worthwhile pressure. Fig 3 shows the velocity diagram for the air flowing into the fan inlet and out of it outlet. In a mixed flow fan the air flows in both axial and radial direction relative to the shaft.
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.
