Axial flow fan is also a very common accessory, and the emergence of axial flow fan has provided great convenience for people's life. It is widely used in many fields and can be seen everywhere in life. So when manufacturers choose axial-flow fans, it's better to choose more or less blades. What's the difference? Let's see the difference. How to choose axial-flow fans.

The number of blades of axial-flow fan is not as many as possible. The number of blades is usually odd. This is because it is easier to calibrate the rotation center of odd blades when doing dynamic balance correction. Ordinary axial-flow fan blades are generally about 5 to 11 blades. At the same speed, the blades have large air volume. In fact, the air volume and wind speed of axial-flow fan are mainly motor power and blade shape design The shape of the fan blade has an effect on the efficiency of the fan, so the best shape of the blade is streamline and proper bending angle, which can reduce the noise and improve the efficiency of the axial-flow fan.

This also needs to be seen from many aspects. It depends on the speed and fan diameter. When the speed and fan diameter of the two fans are equal, the less blades, the more noise, the greater the wind force, the more blades, the less noise, and the smaller the wind force. The more blades an axial fan has, the more energy it consumes. The evaluation of an axial-flow fan is not based on the number of blades, but on a comprehensive index. A manufacturer has a good design and material. When the number and diameter of the same power motor and fan blades are large, the air volume is large, the noise is low, the efficiency is high, and the fan is stable. Such an axial-flow fan is a good fan.

The above is how good or how little the blades of axial flow fan introduced by Dong Xingyue are. To learn more about axial flow fan, please click:http://www.dxymotors.com
