Energy-saving retrofit of axial flow fan

When the axial fan is started, the current of the motor will be 5-6 times higher than the rated, which will not only affect the service life of the motor but also consume more electricity Quantity. The system in the design of the motor selection will leave a certain amount of surplus, the speed of the motor is fixed, but in the actual use of the process, sometimes to run at a lower or higher speed, so it is very necessary to carry out frequency conversion transformation. The inverter can realize the soft start of the motor, achieve the goal of energy-saving speed regulation by changing the input voltage frequency of the equipment, and can provide the equipment with overcurrent, Overvoltage, overload and other protection functions.
