To solve the shortage of wind power and fan surge in pneumatic cut tobacco feeding system, the methods of air compensation through main duct combined with frequency regulation is proposed to adjust the system air flow. A pneumatic system with six units is calculated, the results show that the adjustment ranged of fan frequency from 41 to 50 Hz. Simultaneously, the system should make up the wind while three or more cigarette machine are shut down, and its maximum volume of makeup air in an hour is 3 900 m3/h. The methods of air compensation through main duct combined with frequency regulation could not only ensure the pneumatic cut tobacco feeding system operate effectively and prevent the fan surge, but also improve energy-efficiency for wind power system.
