"Blower Fan" Transmission: Direct coupling to the main. If the performance specifications required, can also be used triangular pulley transmission manner. Couplings couplings, and can ease the impact of the compensation amount of axis deviation. Large flow divided by the fan motor as a driver, but also can be driven turbine or other machine. With the continuous development of technology, AC motor speed control technology is widely adopted. Through a new generation of full-controlled electronic components, with the frequency change of AC motor speed way to control the flow of the fan, can significantly reduce the energy of a conventional mechanical regulation of traffic caused by the loss.
