Mixed flow fan, axial flow fan, centrifugal fan
1. Centrifugal fan airflow enters the rotating blade channel, and the gas is compressed and flows along the radius under the action of centrifugal force.
2, axial flow fan after the air flow into the fan impeller axial, in the flow passage of the rotating blade along the axial direction of the fan. Compared with centrifugal fans, axial flow fans have the characteristics of large flow, small volume, and low pressure head, which should be paid attention to when used for dust and corrosive gas.
3, oblique flow (mixed flow) fan in the impeller of the fan, the direction of the air flow between the axial flow, approximately along the cone flow, so it can be called oblique flow (mixed flow) fan. The pressure coefficient of the fan is higher than that of the axial flow fan, and the flow coefficient is higher than that of the centrifugal fan.
The above pictures are in order: centrifugal, mixed and axial flow
