In the design process, the system of the axial flow fan will have a certain margin in the selection of the motor, the speed of the motor is fixed, but in the process of actual use, it is sometimes necessary to operate at a lower or higher speed, Therefore, it is necessary to carry out frequency conversion transformation. The frequency converter can realize the soft start of the motor, by changing the input voltage and frequency of the equipment to achieve the purpose of energy saving and speed regulation, and can provide protection functions such as over-current, over-voltage, overload and so on to the equipment.
Application of axial flow fan
Can be used for ventilation or heat dissipation in places such as metallurgy, chemical industry, light industry, food, medical equipment, mechanical equipment and civil building. If the casing is removed, it can also be used as a free fan, and can be installed in series at intervals in the long exhaust pipe to improve the wind pressure in the pipeline.
Characteristics of Axial flow Fan
1. The axial flow fan is low in power consumption, fast in heat dissipation, low in noise, energy-saving and environment-friendly. And has wide application range due to small volume.
The large axial flow fan has the characteristics of simple structure, stable and reliable, low noise, large air volume, wide range of function selection and so on.
2. When the axial flow fan is used for slow-speed ventilation, because the air volume of the axial flow fan is small, the other grain is the bad conductor of heat, the ventilation of the individual parts is easy to occur at the beginning of the ventilation, and the whole grain temperature is gradually balanced with the continuous ventilation.www.jnblower.com
