Centrifugal fan is a kind of driven fluid machinery, which depends on the input mechanical energy to increase the gas pressure and discharge the gas. Centrifugal fans are widely used in ventilation, dust removal and cooling of factories, mines, tunnels, cooling towers, vehicles, ships and buildings; Ventilation and induced draft of boilers and industrial furnaces; Cooling and ventilation in air conditioning equipment and household electrical equipment; Drying and selection of grain; Wind tunnel wind source and inflation and propulsion of hovercraft.

According to the scope, high-pressure centrifugal fans are divided into: high-temperature and high-pressure fans, corrosion-resistant high-pressure fans, tunnel and mine high-pressure fans, material conveying high-pressure fans, pressurized high-pressure fans, thermal recycling high-pressure fans and other high-pressure fans.

When using the high-pressure centrifugal fan, the operating environment, such as temperature, corrosivity, gas composition, wear resistance, oxidation resistance, explosion-proof and other conditions, shall be considered.

Centrifugal fan is composed of casing, main shaft, impeller, bearing transmission mechanism and motor.

Casing: made of steel plate, solid and reliable, can be divided into integral type and semi open type, which is convenient for maintenance.

Impeller: composed of blade, curved front disc and flat rear disc.

Rotor: static balance and dynamic balance shall be conducted to ensure stable rotation and good performance.

Transmission part: it is composed of main shaft, bearing box, rolling bearing and belt pulley (or coupling).
