When the axial flow fan is started, the current of the motor will be 5-6 times higher than that of the extra, which will not only affect the service life of the motor but also consume more electricity. System in the design of the motor selection will leave a certain margin, the speed of the motor is fixed, but in the process of practical use, sometimes to a lower or higher speed operation, so the frequency conversion transformation is very necessary.

When the axial flow fan is started, the current of the motor will be 5-6 times higher than that of the extra, which will not only affect the service life of the motor but also consume more electricity. System in the design of the motor selection will leave a certain margin, the speed of the motor is fixed, but in the process of practical use, sometimes to a lower or higher speed operation, so the frequency conversion transformation is very necessary.

The frequency converter can complete the soft start of the motor, reach the intention of energy-saving and speed regulation through changing the input voltage frequency of the equipment, and can provide the equipment with maintenance functions such as overcurrent, overvoltage, overload, etc. The modification of usage occasions can be used for ventilation or strengthening heat dissipation in places such as metallurgy, chemical industry, light industry, food, medical equipment, mechanical equipment and civil buildings.

If the casing is removed, it can also be used as a free electric fan or a series device at intervals in a long exhaust pipe to increase the wind pressure in the pipe. Axial fan features: small axial fan: low power consumption, fast heat dissipation, low noise, energy saving and environmental protection. Because of its small size and wide range of uses, large axial flow fans have the characteristics of simple structure, stability and reliability, low noise, large air volume, and wide range of functions.

The main difference between centrifugal fan and axial fan is that centrifugal fan changes the flow direction of medium in the air duct, while axial fan does not change the flow direction of medium in the air duct. The former device is more complicated. The former motor and the fan are generally connected through a belt-driven rolling wheel, while the latter motor is generally in the fan.
