Diffusion process and working condition requirements of industrial centrifugal fans

- Jun 28, 2019-

Industrial centrifugal fans are just a general term for fans used in the industrial industry. In the process of work, the names can be different depending on the user's application and working conditions.

 

The industrial centrifugal fan is based on the principle that kinetic energy is converted into potential energy. The high-speed rotating impeller accelerates the gas, 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 to cause deceleration, which converts kinetic energy into pressure energy. The increase in pressure mainly occurs in the impeller, followed by the expansion process.

 

Industrial Centrifugal Fans In a multistage centrifugal fan, a return flow is used to direct airflow into the next impeller, resulting in higher pressure. Industrial 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 in air conditioning equipment and household appliances And ventilation, drying and selection of grain, inflation and propulsion of wind tunnel sources and hovercraft.
