What is the difference between centrifugal fan and axial fan?
Do you understand the difference between centrifugal and axial fans?
The main difference between centrifugal fan and axial flow fan lies in the following aspects:
1. The centrifugal fan changes the flow direction of the medium in the air duct, while the axial flow fan does not change the flow direction of the medium in the air duct;
2. centrifugal roof fan installation is more complex;
3.he former motor and fan are generally connected through the shaft, the latter motor is generally in the fan;
4.the former is often installed in the air conditioning unit inlet and outlet, boiler drum, induced draft fan and so on. The latter is often installed in the air duct, or the front end of the air duct outlet.
Centrifugal fan is dependent on the input of mechanical energy, improve the gas pressure side by side to send gas machinery, it is a driven fluid machinery. Centrifugal fans are widely used for ventilation, dust removal and cooling in factories, mines, tunnels, cooling towers, vehicles, ships and buildings; Ventilation and ventilation of boilers and industrial furnaces; Cooling and ventilation in air conditioning equipment and household electrical equipment; Drying and selection of grain; Wind tunnel wind source and air cushion aeration and propulsion, etc.
Axial flow fan is the air flow in the same direction as the axis of the blade, such as electric fan, air conditioning fan is the axial flow mode of operation fan. It is called "axial flow" because the gas flows parallel to the fan axis. Axial flow fans are usually used in situations with higher flow requirements and lower pressure requirements. Axial fans hold the position and move the air.
The centrifugal fan mainly changes the flow direction of the medium in the duct, and the axial flow fan cannot change the flow direction of the medium, which is also between them. For an important distinction. And the air volume and air pressure of the centrifugal fan are very large, but the air pressure and air volume of the axial fan are much smaller.
The installation of centrifugal fan is very complicated, while the axial flow fan is very simple in the installation, and the installation cycle is very short. There is also a certain difference between the installation of centrifugal fans and axial fans. Users can take a look at this point. The motors of centrifugal fans are connected with the fan through the shaft, while the fan of axial flow fans is directly installed inside the fan.
