Axial flow fan diagram.

The shape of your blades and the direction they travel will define the performance characteristics of your fan. 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. Conversion 460 230 volt 30.

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. 16 17 b the difference in the shape of axial flow turbines and axial flow compressor is illustrated. Axial flow fans this manual is for installation operation and maintenance of all caldwell axial fans with serial numbers. 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. 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 have developed rapidly since the second world war due to the creation of a range of high strength aluminium alloys. Wiring schematic for 575 volt three phase axial fan 28 figure 22.

The axial flow compressors can be of impulse type or reaction type.
