The reasons why wear parts of the fan is not uniform is that the uneven distribution of solid particles in the air.

In general, the wear is serious in big concentration place, while the wear is light in small concentration places.
Using the front wear resistant blade cascade or increasing the guide vane are based on the perspective of gas dynamics, control particle motion to uniform distribution, and then reduce the wear and tear.
After the impeller installed front wear resistant blade cascade or increasing the guide vane, and they will rotate with the impeller rotation. In this case, generate airflow to dispel the particle beam; force to reduce their orbit radius; prevent the particle move back to rear plate and the blade root; make the solid particles uniform distribution along the impeller; thus convert the particle concentration wear to even wear; finally, improve centrifugal fan impeller wear ability and prolong the service life.
