How much do you know about the characteristics of axial flow fans?
During startup after energy-saving modifications, the current of the axial flow fan motor will be 5-6 times higher than normal, affecting not only the motor's lifespan but also consuming excessive electricity. While the system design includes a certain margin in motor selection, and the motor speed is fixed, practical applications sometimes require operation at lower or higher speeds, making variable frequency conversion essential.
The frequency converter enables soft motor startup, achieving energy-saving speed regulation by adjusting the input voltage frequency, and provides protection functions such as overcurrent, overvoltage, and overload protection. Modified applications are suitable for ventilation and heat dissipation in metallurgy, chemical, light industry, food, pharmaceutical equipment, machinery, and civil buildings.
Removing the casing allows use as a free-standing fan, or multiple units can be connected in series within a long exhaust duct to increase duct pressure. Axial flow fan features: Small axial flow fans: low power consumption, fast heat dissipation, low noise, energy saving, and environmental protection. Due to their small size, they have a wide range of applications. Large axial flow fans feature simple structure, stable and reliable operation, low noise, large air volume, and a wide range of performance options.
Difference Description The main difference between centrifugal and axial flow fans lies in the fact that centrifugal fans change the flow direction of the medium in the duct, while axial flow fans do not; the former is more complex to install; the former's motor and fan are generally connected via a belt-driven roller, while the latter's motor is generally inside the fan.
