The centrifugal fan fan adopts the single suction D type transmission structure, and the fan and the motor connect through the coupling. The fan body of centrifugal fan is mainly composed of shell, air inlet, rotor group (impeller and spindle), bearing shell, coupling and so on. (F transmission is double support two bearing boxes, single suction has an intake chamber, double suction two intake chambers. C, B type transmission has driving and passive wheels.

 
 
Apart from the fan body, the centrifugal fan can also equip all kinds of external accessories according to the needs of users. Common are: motor, conditioning door, all bracket, electric actuator, muffler and so on. Fans can be divided into two types: forward or reverse: starting from the end of the motor, if the centrifugal fan rotates clockwise in the impeller, it is called "Shun"; in the counterclockwise direction, it is "reverse".
 
The outlet position of the fan is shown by the outlet view of the centrifugal fan housing. The "Shun" and "reverse" can be divided into six viewpoints: 0 degrees, 45 degrees, 90 degrees, 135 degrees, 180 degrees and 225 degrees. Other special viewpoints can also be made according to user requirements. According to the specific situation, the bearing seat has two types: water cooling bearing box and oil cooling bearing box. When the surrounding environment has strict requirements for the noise of the equipment used, noise elimination and sound insulation should be done in addition to dealing with the noise reduction and vibration reduction of centrifugal fans.
 
For fans, sound insulation cover is used. The sound insulation cover of fans is made of various shapes according to the type and size of fans. It is made up of a number of standard or non-standard sound insulation boards, and can also be made into all covers. The hood is provided with fan inlet and overhaul door, all other parts are closed. An exhaust pipe is installed at the top of the hood to remove heat from the motor.
