What are the types of centrifugal fans?

 Centrifugal fans are widely used as gas transmission driving forces. What are the classifications of centrifugal fans? 

Centrifugal fans can be divided into general centrifugal fans, dust exhaust fans and anti-corrosion centrifugal air according to the type of material transported Machine, explosion-proof axial fan four types. Generally, centrifugal fans are used for transportation. The ambient temperature shall not exceed 80℃, the smoke concentration shall not exceed 150mg per cubic meter, and the gas transported will not corrode the machinery and equipment. Dust blower is used to transport smoke and dust If the concentration exceeds 150mg per cubic meter, the dust blower can also be used as mechanical equipment for pneumatic conveying system. Dust fan through special solution, not easy to be blocked by dust, shell more resistant to wear. Corrosion - resistant centrifugal fan is used to transport steam which is irritating to metal materials. Corrosion resistant centrifugal fans are usually made of stainless steel plate, plastic or porcelain and other corrosion resistant materials, or coated with corrosion resistant metal materials Building paint. Explosion-proof axial flow fans are used for transportation of steam bodies that are very easy to cause deflagration and ignition, or gases with some kind of industrial dust that are likely to cause deflagration, or for inflammable, inflammable and explosive The environment. Its shell and centrifugal impeller with soft metal products, explosion-proof axial fan power device suitable for explosion-proof fans.
