Centrifugal fans are widely used as the transmission power of air. What are the classifications of centrifugal fans? Centrifugal fans can be divided into four categories according to the nature of the conveying medium: ordinary fans, dust fans, corrosion-resistant fans, and explosion-proof fans. The ordinary fan is used to transport relatively clean, the temperature is not more than 80 ℃, the dust concentration is not more than 150 mg per cubic meter, and the air transported is not corrosive to the equipment. The dust exhaust fan is used to transport air with a dust concentration of more than 150 mg per cubic meter, and the dust exhaust fan can also be used as a pneumatic conveying machine. The dust exhaust fan is specially treated and is not easily blocked by dust, and the shell is relatively wear-resistant. Corrosion-resistant fans are used to convey corrosive gases to metal materials. Corrosion-resistant fans are usually made of corrosion-resistant materials such as stainless steel, plastic or ceramic, or coated with corrosion-resistant coatings on metal materials. Explosion-proof fans are used to transport gases that are prone to explosion and combustion, or air that contains some industrial dust that may cause an explosion, or for flammable and explosive environments. Its shell and impeller are made of soft metal, and the power source of explosion-proof fan is equipped with explosion-proof motor.
