What are the differences between axial fan and centrifugal fan?

The working principle of the axial flow fan is that when the impeller rotates, the gas enters the impeller axially from the air inlet, is pushed by the blades on the impeller to increase the energy of the gas, and then flows into the guide vane. The guide vane changes the deflected airflow into an axial flow, and at the same time introduces the gas into the diffuser tube, further converts the kinetic energy of the gas into pressure energy, and finally introduces it into the working pipeline. The working principle of a centrifugal fan is based on the principle of converting kinetic energy into potential energy, using a high-speed rotating impeller to accelerate the gas, then decelerate, change the flow direction, and convert kinetic energy into potential energy (pressure). In a single-stage centrifugal fan, the gas enters the impeller from the axial direction, changes to the radial direction when the gas flows through the impeller, and then enters the diffuser. So what are the differences between axial fan and centrifugal fan?

The difference between axial fan and centrifugal fan:

First, the exhaust direction of the axial fan and centrifugal fan are different: The exhaust direction of the axial fan is straight along the direction of the axis, the air inlet and the air outlet of the fan are on a parallel axis, and the exhaust direction of the centrifugal fan is perpendicular to the direction of the air inlet, which can be specified Exhaust in the direction.

Second, the installation degree of axial fan and centrifugal fan are different: The installation of axial flow fan is relatively simple, generally it is directly installed on the wall or connected to the air duct. Centrifugal fan installation is more complicated.

Third, the air volume and pressure of the axial fan and centrifugal fan are different: The air volume and pressure of the axial flow fan are relatively small, and there is basically no air pressure, while the air volume and pressure of the centrifugal fan are relatively high. Use a centrifugal fan.

Fourth, the appearance and shape of the axial fan and centrifugal fan are different: The appearance of the axial fan is basically cylindrical, and the appearance of the centrifugal fan is snail-shaped.

Fifth, the motor connection methods of the axial fan and the centrifugal fan are different: The motor connection of the axial flow fan is generally in the body of the fan, and the motor of the centrifugal fan is connected by the shaft, which is usually externally installed outside the fan suction tube.
