Axial fans are airflow in the same direction as the axis of the blades (that is, the direction of the wind is parallel to the axis), such as electric fans, air conditioners and external fans are fans that operate in axial flow.
A common example of an axial fan is a typical desktop fan. It is called "axial flow" because the air passing through the fan does not change direction, but flows parallel to the fan axis. Axial fans are usually used on occasions with higher flow requirements and lower pressure requirements.
The blades of an axial flow fan work similarly to the wings of an airplane. However, the latter applies to lift upwards on the wings and supports the weight of the aircraft, while the axial flow fan fixes the position and moves the air.
The cross-section of an axial fan is generally a wing section. The blade can be fixed in position, or it can rotate around its longitudinal axis. The angle between the blades and the airflow or the distance between the blades may not be adjustable or adjustable. Changing the blade angle or pitch is one of the main advantages of axial fans. A small blade pitch angle produces a lower flow rate while increasing the pitch can produce a higher flow rate.
Advanced axial-flow fans can change the blade pitch when the fan is running (this is quite similar to a helicopter rotor), thereby changing the flow accordingly. This is called a variable blade (VP) axial fan.
The axial fan is also called a local fan. It is a kind of fan commonly used in industrial and mining enterprises. It is different from ordinary fans. It's motor and blades are in a cylinder. The shape is a cylindrical shape. It is used for local ventilation and is easy to install. The ventilation effect is obvious and safe, and the wind can be connected to the air duct to send the wind to the designated area.
What is the difference between an axial fan and a negative pressure fan
As we all know, many high-temperature workshops are equipped with a large number of axial fans, but the workshop is still so stuffy and hot, and there is still so much dust and a peculiar smell.
Rarely can drive the surrounding air.
The example shows that if everyone is standing next to the axis of the axial flow fan, you will not feel the airflow at all, although there is a lot of wind on the axis.
The negative pressure fan is like a reverse sprayer. It absorbs air in a horn-like shape. It not only drives the airflow on the fan axis but also scrolls the air in a horn-like shape from the fan. We stand on the impeller feeder. A strong airflow will also be felt next to the fan axis. This characteristic determines the thoroughness and high efficiency of its exhaust.
