Abstract
The utility model relates to a traction fan for a high-power internal combustion locomotive. A deep tongue volute structure is adopted to increase traction fan static pressure, and meanwhile, an airfoil vane wheel structure is adopted, vanes are airfoil vanes which have excellent aerodynamic performance, so that traction fan sound pressure level is smaller than 106 dB(A). A motor base is fixed on a motor installing plate through a bolt, the bottom of the motor installing plate is welded together with the volute, so that rigidity of the motor is greatly improved, vibration of the traction fan for the high-power internal combustion locomotive is reduced, and vibrating speed is guaranteed to be less than 4.5 mm/s. The volute is welded by low-alloy and high-intensity steel which is excellent in intensity, so that overall intensity of the traction fan for the high-power internal combustion locomotive can be ensured, and locomotive vibratory impacting requirements can be met. Vane wheels are airfoil centrifugal vane wheels and of an integrally casted structure, so that appearance is attractive, and aerodynamic performance of the traction fan for the high-power internal combustion locomotive is excellent. Due to the excellent aerodynamic performance of the airfoil vanes, spaces of air inlets, the vane wheels and the volute are optimally arranged, and efficiency of the traction fan for the high-power internal combustion locomotive can reach a best level.
