A common example of axial fans is typical desktop fans. It is called axial flow because the air passing through the fan does not change direction, but is parallel to the air shaft. Axial fans are usually used in situations where the flow rate is high and the pressure requirement is low.
Axial fan blades work like the wings of an airplane. The latter, however, forces the lift upwards on the wings and supports the weight of the aircraft, while the axial fan positions and moves the air.
The cross section of axial fan is generally wing section. The blade can be fixed or rotated around its longitudinal axis. The angle of the blade or the airflow or the pitch of the blade can be adjustable or adjustable. Changing the blade angle or pitch is one of the main advantages of axial fans. The pitch of the interlobular leaves creates a lower flow rate, while the increase in spacing leads to higher flow rates.
The advanced axial fan can change the blade spacing (which is quite similar to the helicopter rotor) when the fan is operating, thus changing the flow accordingly. This is called an adjustable blade (VP) axial fan.
Also called the local fan axial flow fan is a fan used in industrial and mining enterprises, security is different from its general fan motor and fan blades are in a cylinder shape is in a cylinder shape, for local ventilation, convenient installation, ventilation effect, safety, can be connected with the air duct the wind sent to the designated area.
