Application characteristics and Start-up process of Axial Fan

Jan 03, 2019

When the axial flow fan starts up, the current of its motor will be 5-6 times higher than the rated one, which will not only affect the service life of the motor but also consume more electric energy. When the system is designed, there will be a certain margin in the selection of the motor, and the speed of the motor is fixed. However, in the process of practical use, it is necessary to operate at a lower or higher speed, so it is very necessary to transform the frequency conversion. The inverter can realize the soft start of the motor, achieve the purpose of energy saving and speed regulation by changing the input voltage frequency of the equipment, and can provide protection functions for the equipment such as overcurrent, overvoltage, overload and so on.

 

Characteristics of Axial flow Fan

Small axial fan: low power consumption, fast heat dissipation, low noise, energy saving and environmental protection. Because of its small size, it is widely used.

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.www.jnblower.com
