Description
Technical Field

Background
The centrifugal fan is a driven fluid machine which increases the pressure of gas and discharges the gas by means of input mechanical energy. Centrifugal fans are widely used in ventilation, dust removal and cooling of factories, mines, tunnels, cooling towers, vehicles, ships and buildings; ventilation and draught of boilers and industrial furnaces; cooling and ventilation in air conditioning equipment and household appliances; drying and selecting grains; wind tunnel wind source and air cushion boat inflation and propulsion. The centrifugal fan accelerates gas by using an impeller rotating at a high speed according to the principle that kinetic energy is converted into potential energy, and then decelerates and changes the flow direction so as to convert the kinetic energy into the potential energy (pressure). In a single stage centrifugal fan, the gas enters the impeller from an axial direction, changes to a radial direction as it flows through the impeller, and then enters the diffuser. In diffusers, the gas changes flow direction and the increase in conduit cross-sectional area slows the gas flow, which converts kinetic energy into pressure energy. The pressure increase occurs primarily in the impeller and secondarily in the diffusion process. In a multistage centrifugal fan, a flow reverser is used to direct the air flow to the next impeller, creating a higher pressure.
