9-28 centrifugal fan is a very powerful fan type, that is, by virtue of this, it can be applied in many areas. Then someone will ask, such a centrifugal fan is by virtue of what to effectively improve the efficiency of it?
In fact, very simple, the so-called centrifugal fan is only a form of the fan, the reason to be able to improve so much power, a large part of the reason is determined by the fan of this fan. The so-called impeller is the fan we usually see the fans, many people think that the efficiency of the fan is due to its faster speed. Yes, the efficiency of the fan is a direct relationship with the speed of the fan.
But the impeller is a more energy-saving measure, to ensure that it is to improve efficiency while using the same power. Impeller can improve the efficiency of centrifugal fan has two advantages, one is the size of the impeller diameter, the other is the impeller tilt.
If the diameter of the impeller is relatively large, that is to say that the centrifugal fan model is large enough. Then the power will be effective to enhance, which is why the power of the larger fan in the volume are relatively large reasons.
There is the degree of tilt of the centrifugal fan impeller, if the tilt is relatively small, then the power will be relatively small. On the other hand, if the degree of tilt is large, then the power of the centrifugal fan will become larger. But this is also within a certain range, because after all, the impeller is not the way to tilt the ninety degrees, at most, that is, within an acute angle, if not, then the centrifugal fan will be in the life of the impeller Relatively short.
So, if you want to increase the efficiency of the centrifugal fan at the same time as the same current, only from the impeller of the fan to improve.
