What is the role of the fan?
Gas compression and gas transport machinery is the conversion of mechanical energy into gas pressure energy and kinetic energy, and the gas transported out of the machinery.
Only because the gas flow rate is low, the pressure changes little, generally do not need to consider the gas specific volume changes, that is, the gas as incompressible fluid treatment.
Grain drying and selection; wind tunnel and hovercraft inflatable and propulsion, etc. The working principle of the fan and turbine compressor is basically the same,
Ventilation and induced winds for boilers and industrial furnaces; cooling and ventilation in air conditioning and household appliances
Fans are widely used in factories, mines, tunnels, cooling towers, vehicles, ships and buildings for ventilation, dust and cooling
