The Role of Fan Shell and Volute Tongue in the Centrifugal Blower Fan
The centrifugal blower fan has a simple and compact structure.
It is composed of impellers, motors, air inlets, air valves, air outlets, and other components.
Each component is an indispensable part and has its own unique function.
As small parts of a centrifugal blower fan, volute shell and volute tongue play an irreplaceable role.
Today we focus on explaining the role of the volute shell and volute tongue.
So what are the effects of the shape and size of the volute shell and volute tongue in the centrifugal blower fan on the efficiency of the entire device?
Now let us explain in detail:
Centrifugal Blower Fan Volute Shell(Housing)
The shape of the centrifugal blower fan volute tongue is a logarithmic spiral.
Its main function is to collect the gas thrown out of the impeller and allow these gases to flow to the exhaust port.
During the gas flow, the gas can be converted from kinetic pressure energy to static pressure energy at the centrifugal blower fan wheel. , Thus forming wind pressure.
The centrifugal blower fan volute tongue is equipped with an outlet diffuser.
This is to make the airflow out of the volute tongue deflect toward the impeller.
Generally, the diffuser needs to be designed in the same direction as the fan wheel.
Centrifugal Blower Fan Volute Tongue (CutoffPlate)
The outlet of the centrifugal blower fan is designed with a volute tongue, which has a tongue-like structure.
Its main function is to prevent gas from circulating in the casing.
There is a gap between the centrifugal blower fan volute tongue and the outer diameter of the impeller when it is designed.
The size of the gap has a great influence on the noise of the work.
If the gap is relatively small, the noise is relatively large, and if the gap is relatively large, the noise is relatively small.
The shape of the centrifugal blower fan volute tongue is a circular arc.
Although the circular arc does not have a great impact on the aerodynamic force of the fan, it has a relatively large impact on noise.
Normally, if the radius of the arc is small, the noise is high, and vice versa, the noise is small.
In summary, volute shell and volute tongue play an important role in centrifugal blower fan, and the rationality of these two parts is directly related to the performance and effect of the equipment.
