In order to make centrifugal fan meet the requirement of high-speed operation, the assembly requirements and technology of centrifugal fan impeller are improved properly. First of all, it is necessary to ensure that there is a certain safety interval between centrifugal fan impeller and inlet. So the width of the impeller is a little smaller than the other.

secondly , in order to ensure that the impeller can be smoothly mounted to the centrifugal fan , the outer diameter of the impeller should also be reduced , and meanwhile , the machining process performance of the impeller is improved , so as to facilitate the processing and forming of the accessories and the total installation of the blades and the wheel disc and the wheel cover , and the number of the impeller blades is less than the number of the original impeller blades .

At the same time, the strength and stiffness of all impellers are higher than that of original impellers in order to satisfy the necessary safety coefficient of centrifugal fan. The air dynamic performance of the new impeller fan is better than that of the original impeller fan, and the centrifugal fan impeller should be rotated correctly.

Since the centrifugal fan impellers have changed, then its assembly technology will be different, because the number of blades to reduce, in order to ensure the welding of each blade and wheel. The verticality of the cover and the uniform distribution on the circumference make the full welding between the blades and the wheel disc and the cover of the wheel can be carried out smoothly.

The test shows that the change of impeller not only makes the centrifugal fan run at high speed, but also can get better use effect. Both efficiency and energy consumption are much better than before. When the centrifugal fan is put into practice, it is sure to bring more significant effect to the user.http://www.jnblower.com/
