How is the suction of the centrifugal fan measured?
Heart fan is based on the principle of kinetic energy conversion to potential energy, the use of high-speed rotation of the impeller to accelerate the gas, and then slow down, change the flow, so that kinetic energy into potential energy (pressure).
Boiler and industrial furnace ventilation and wind; air conditioning equipment and household appliances in the cooling and ventilation; grain drying and selection; wind tunnel and hovercraft inflatable and propulsion.
Centrifugal fans are mechanical machines that rely on the input of mechanical energy to increase the gas pressure and send the gas, which is a driven fluid machine. Centrifugal fans are widely used in factories, mines, tunnels, cooling towers, vehicles, ships and buildings for ventilation, dust and cooling;
In a single-stage centrifugal fan, the gas enters the impeller from the axial direction, the gas flows into the radial direction when passing through the impeller, and then enters the diffuser
In the diffuser, the gas changes the flow direction to cause deceleration, which slows the kinetic energy into pressure energy. The increase in pressure mainly occurs in the impeller, followed by the expansion process
