In order to realize the real value of the fan, we should pay attention to the control of the air volume in the process of using the centrifugal fan in the power station, so that the ventilation and air exchange can be well reflected. Before we understand the control of air volume, we need to understand some of the principles of centrifugal fan, so as to help users to better control the air volume.

Centrifugal fans in power stations use high-speed rotating impellers to accelerate the gas, then slow down, change the flow direction, and convert kinetic energy into potential energy. In a single-stage centrifugal fan, the gas enters the impeller from the axial direction, and the gas changes into the radial direction when passing through the impeller, and then enters the diffuser.

In the diffuser of centrifugal fan in power station, the gas changes the flow direction and causes deceleration, which converts kinetic energy into pressure energy. The pressure increase occurred mainly in the impeller, and then in the spreading process. In the multi-stage centrifugal fan, the air flow enters the next impeller with a backflow device, resulting in higher pressure.http://www.jnblower.com/
