Optimization Design and Industrial Application of Blade Profile for Mining Axial Fan
The guide wheel blade shape is a key structural parameter of a fan.The blade structure of FBCDNo14 axial flow fan is studied,and optimization design work is carried out based on orthogonal experimental ideas and Fluent software.The optimization object is the installation angle of 6 sections along the radial direction of the blade,and the optimization goal is the efficiency and total pressure of the ventilation fan.It was found that changing the blade structure can improve the total pressure and efficiency of the equipment to a certain extent Compared with the original structure,the new structure has increased the total pressure and efficiency by 7.76％and 7.17％,respectively.Applying the optimized blade structure to coal mine engineering,it was found that the wind speed of the coal mine working face increased by 14.21％,the gas concentration decreased by 27.63％,and the temperature decreased by 8％,playing a greater role in ensuring mine safety.
