Axial fan

Axial flow fan is the air flow in the same direction as the axis of the fan blade, such as electric fan, and the external air conditioner fan is the axial flow fan. It is called "axial flow" because the gas flows parallel to the fan axis. Axial fans are usually used where there is a high flow requirement and a low pressure requirement. Axial fans fix the position and move the air.

Fundamentals Axial fan blades work like airplane wings. However, the latter applies lift to the wing and supports the weight of the aircraft, while the axial fan fixes the position and moves the air.

Axial fan cross-section is generally an airfoil profile. The blades can be fixed in position or they can rotate about their longitudinal axis. The angle between the blades and the airflow or the spacing between the blades may not be adjustable or adjustable. Changing the blade angle or pitch is one of the main advantages of axial flow fans. Small blade pitch angles produce lower flow rates, while increasing pitch creates higher flow rates.

Advanced axial fans can change the blade pitch when the fan is running (which is quite similar to a helicopter rotor), which changes the flow accordingly. This is called a VP axial flow fan.

Axial flow fan is also called local fan. It is a kind of fan commonly used by industrial and mining enterprises. An electric fan and fan blades are different from a common fan in a cylinder. The shape is a cylinder, used for local ventilation, and easy to install. The air ventilation effect is obvious and safe, and the air receiver can send the air to the designated area.

The classifier Lindong Fan made the following classification based on the characteristics of the axial fan:

According to material classification: steel fan, glass steel fan, plastic fan, PP fan, PVC fan, aluminum fan, stainless steel fan, etc. According to the use of classification: explosion-proof fan, anti-corrosion fan, explosion-proof anti-corrosion fan and other types.

According to the requirements of the use of classification: pipeline, wall, post, fixed, rain and dustproof, motor external and so on.

Inverter's energy-saving application on the axial fan When the axial fan is started, the current of the motor will be 5-6 times higher than the rated value. This will not only affect the service life of the motor but also consume more electricity.
