Teach you how to choose axial flow fan

Teach you how to choose axial flow fan axial flow fan is also a very common accessory, the axial flow fan is presented to provide great convenience for people's days. The scope of application is very common, and can be seen everywhere in the day. So manufacturers in the selection of axial fans in the end is the selection of more leaves or leaves less, what are the differences? Here we look at the differences and how to pick axial flow fan.

Axial flow fan is not that the more blades the better, the number of blades is usually odd, this is because the odd number of blades in the dynamic balance calibration is easier to calibrate the center of rotation, and the average axial fan blade is generally about 5 to 11, the same speed, the greater the blade air volume, the greater the axial flow fan air volume, the smaller the wind speed.

Mainly related to the motor power and fan blade shape. The shape of the fan blade has an impact on the power of the fan. Thus, the shape of the blade should be streamlined and suitable bending angle, which can reduce the noise and improve the power of the axial fan. This also needs to be seen in many ways, depending on the speed and diameter of the fan.

When the speed and diameter of the two fans are equal, the less blades, the more noise, the more wind, the more blades, the less noise, the less wind. Axial fans The more blades they have, the more energy they consume. The good or bad of an axial fan is not judged by the number of blades, but selected from an inductive index. A manufacturer with good design, good materials, the same power of the motor blade number and diameter are large air volume, low noise, high power, stable fan, so the axial fan is a good fan.
