Working process and potential energy principle of centrifugal blower for air shower

- Jun 14, 2019-

The centrifugal blower for air shower mainly relies on the input mechanical energy during the working process, and can effectively increase the gas pressure and discharge the gas when it is used. It is a driven fluid machine. Centrifugal fans are widely used for ventilation, dust extraction and cooling in factories, mines, tunnels, cooling towers, vehicles, ships and buildings; ventilation and air intake in boilers and industrial furnaces; cooling and cooling in air conditioning equipment and household appliances Ventilation; drying and selection of grain; inflation and propulsion of wind tunnel sources and hovercraft.

 

The air shower chamber centrifugal blower can effectively convert the gas into a potential energy according to the principle of its kinetic energy, and accelerates the gas with a high-speed rotating impeller, then decelerates and changes the flow direction, so that the kinetic energy is converted into potential energy (pressure). In a single-stage centrifugal fan, gas enters the impeller from the axial direction, and the gas changes to a radial direction as it flows through the impeller, and then enters the diffuser. In the diffuser, the gas changes the direction of flow and the cross-sectional area of the pipe increases to slow the flow. This deceleration converts kinetic energy into pressure energy. The increase in pressure mainly occurs in the impeller, followed by the expansion process. In a multistage centrifugal fan, a return flow is used to bring the gas stream into the next impeller, resulting in higher pressure.
