Airfoil Centrifugal Fan

Multi-wing centrifugal fans are widely used for ventilation, dust removal and cooling in factories, mines, tunnels, cooling towers, vehicles, ships and buildings; ventilation and induced draft in boilers and industrial furnaces.

Air conditioning equipment and household appliances Cooling and ventilation; drying and delivery of cereals; wind tunnel wind sources and hovercrafts for inflation and propulsion.

Fan structure:

1. The Multi-wing centrifugal fan is generally composed of an impeller, a casing, a current collector, a motor and a transmission member (such as a main shaft, a pulley, a bearing, a V-belt, etc.).

2. The impeller consists of a wheel, a blade (the number of blades is generally 8 to 16), a wheel cover, and a shaft disk. The casing consists of a worm plate, side plates and legs. Centrifugal fans can use blades forward or backward blades, which are more adaptable to wind pressure requirements. In addition, the cabinet can be used for noise elimination and has obvious advantages in terms of noise indicators.

3. Motors and fans are generally connected by shafts. Multi-wing centrifugal wind can be made into two types: right-handed and left-handed. From the side of the motor, the impeller rotates clockwise, called the right rotary fan, and rotates counterclockwise, which is called left-handed rotation.
