The size of the impeller of the centrifugal fan directly affects the efficiency

Centrifugal fans are widely used in all walks of life with their good performance. The reason why they are very popular is because of their performance and functions, but it is also a relatively powerful device. The use efficiency should ensure that its power can meet the use requirements, and the size of the impeller often directly affects its use efficiency.

There are many situations of fans, and the centrifugal fan is only one of them, but its working efficiency is much improved compared with other fans. One of the big reasons is its impeller. However, many people simply think that the efficiency of the fan is improved because of the fast speed.

Of course, it is undeniable that the improvement of the working efficiency of the fan is related to the speed, but the impeller can ensure that the fan maintains its working efficiency while the power consumption does not change.

There are two factors that the impeller can improve the working efficiency of the centrifugal fan: one is the diameter of the impeller, and the other is the inclination of the impeller.

If the diameter of the impeller of the fan is large, it means that the model is also relatively large, and the natural power will increase, which is why the fans with relatively large power we see tend to be relatively large in size.

In addition, the degree of inclination of the impeller is relatively small, and the power of the general fan is relatively small. If the degree of inclination is large, the power will be relatively large, but the inclination is limited in scope after all, and the curve needs to be within an acute angle range, which is generally not possible. Vertical, if inclined ninety degrees, it is easy to shorten the life of the impeller.
