Centrifugal fan is a kind of fan with high power, which can be applied in many fields. Then someone will ask, such a centrifugal fan is relying on what to smoothly raise the rate?
In fact, it's very simple. The so-called centrifugal fan is only a form of fan. The reason why it can do so much good in power is largely due to the impeller of this kind of fan. The so-called impeller is the fan blade of the fan that we usually see. Many people think that the fan speed is relatively fast. Yes, the fan work rate is directly related to the fan speed.
But the impeller is a more energy-saving measures, can be reliable, it uses the same electric energy at the same time. Impeller can do a good job of centrifugal fan, the conclusion rate has two aspects, one is the diameter of the impeller, the other is the inclination of the impeller.
If the impeller diameter is relatively large, that is to say, the centrifugal fan model is large enough. Then the power will rise smoothly, which is why all fans with large power are larger in volume.
There is centrifugal fan impeller tilt, if the tilt is relatively small, then the power will be relatively small. On the contrary, if the inclination is large, then the power of the centrifugal fan will become larger. But this is also within the scope of, because after all, there is no way for the inclination of the impeller to reach 90 degrees, which is within an acute angle. Otherwise, the life of the impeller of this centrifugal fan will be shorter.
Therefore, if you want to increase the conclusion rate of centrifugal fan with the same current, you have to improve the impeller of the fan.
