FAN ACCESSORIES

Application

The impeller is the main working part of the centrifugal fan, and the wear resistance and service life of the centrifugal fan mainly depend on the impeller. The impeller is composed of wheel disc, wheel core, blade and wheel cover. The blades are evenly distributed along the circumference of the wheel disc. The wheel core is connected with the wheel cover by bolts, the lower end of the blade is fixedly connected with the wheel disc, the upper end of the blade is fixedly connected with the wheel cover, and the wheel core is installed on the main shaft to drive the impeller to rotate; Among them, the wheel cover section is curved, the blade is usually wing-shaped or straight veneer, and the working surface of the blade is welded with wear-resistant alloy.
