Aerodynamic performance contrast test before and after improvement of local fans for mines
Abstract：Aiming at the problems of local fans using in a Fuxin mine,such as the electricity of impeller motor is much higher,the life of impeller bearing curtail,operation performance of fans declines,the aerodynamic performance is poor.From the airfoil,researched the influence of the fan airfoil on the aerodynamic and operation performance,thus selected a RAF airfoil to replace the original biconvex airfoil,and built the 3D models of the improved prototype and original fan by Proe.Worked out the simulation of internal flowfield of the improvement and original fans by Fluent,the simulation flowfield and the calculated parameters of the flowfield can prove the effects of the improved airfoil to the aerodynamic performance,thus reducing the extra load of drive motor,the work current and the impeller vibration,improving fan bearing life.
