 Product Features 

Introduction Of Centrifugal Fan


When the fan is working, the airflow enters the blade space from the fan axially, and then rotates with the impeller under the drive of the impeller; on the other hand, it increases energy under the action of inertia, leaves the impeller along the radius, and does work by the centrifugal force generated. The fan is called a centrifugal fan.


The main components of the centrifugal fan are: impeller, casing, coupling and shaft. The impeller is the main work component that generates wind pressure and transfers energy; the casing is mainly used to introduce gas and exhaust gas, and at the same time convert part of the kinetic energy of the gas into pressure energy; the coupling is used to connect the motor and the fan to transmit torque;the shaft is installed with the motor through a coupling and the impeller is fixed.


The centrifugal fan is mainly composed of an impeller and a casing. The impeller of the small fan is directly mounted on the motor, and the large fan is connected with the motor through a coupling or a pulley.


Centrifugal fans generally use single-side air intake and use single-stage impellers; those with large flow can be air-intaken on both sides and use two back-to-back impellers, which are also called double-suction centrifugal fans.


The principle of gas discharge: When the gas between the blades of the centrifugal fan rotates, the kinetic energy obtained by the centrifugal force is discharged from the periphery of the impeller, guided by the volute-shaped casing, so that it flows to the outlet of the ventilator, thereby being in the center of the impeller. Negative pressure is formed in the part, so that the external airflow continuously flows in and supplements, so that the fan can discharge the gas.
