Working principle of centrifugal fan
Centrifugal fans are widely used. Next, this article takes you to understand what is Jiangxi centrifugal fan and what are its working principles. If you are interested in this, please come and learn it together. Centrifugal fan is a kind of driven fluid machinery that depends on the input mechanical energy to improve the gas pressure and send gas side by side. Centrifugal fans are widely used in factories, mines, tunnels, cooling towers, vehicles, ships and buildings for ventilation, dust removal and cooling; Ventilation and ventilation of boilers and industrial furnaces; Cooling and ventilation in air conditioning equipment and household electrical equipment; Drying and selection of grains; Wind tunnel, wind source and air cushion aeration and propulsion, etc. Working principle: Centrifugal fan is based on the principle of converting kinetic energy into potential energy, using the high-speed rotating impeller to accelerate the gas, and then decelerate, change the flow direction, so that kinetic energy into potential energy (pressure). In a single-stage centrifugal fan, the gas enters the impeller from the axial direction, changes radial when the gas flows through the impeller, and then enters the diffuser. In a diffuser, the gaschanges direction of flow and the increased section area of the pipe slows the flow. This deceleration converts kinetic energy into pressure energy. The pressure increase mainly occurs in the impeller, followed by the process of diffuser. In a multistage centrifugal fan, a refluxer is used to flow the air into the next blade to produce a higher pressure.
