矿用轴流通风机设计及性能探讨

应用非均匀有理B样条函数进行了轴流通风机叶片计算机辅助几何设计,分析了某煤矿用防爆轴流通风机叶片设计的基本方法。对矿用轴流通风机BK40-4-No10的叶片进行设计,并建立了相应的通风机模型。对3种不同变环量指数叶片的轴流通风机进行数值模拟,得到了风压、功率和全压效率与质量流量的变化曲线,以及这3个性能参数随不同变环量指数的变化趋势。

Design and Characteristic Exploration of Goal Mine Axial Flow Fan

The computer aided geometric design of axial flow fan blades is presented with the non-uniform rational B-spline function.The basic design method of the coal mine explosion-proof axial flow fan blades is analyzed.The coal mine axial flow fan BK40-4-No10 is established to design the impeller.A numerical simulation of three different non-constant circulation index of axial flow fan blade is presented.The curve of pressure,power and full pressure efficiency with the changes of mass flow,and the trend of the three parameters with the changes of different non-constant circulation index were gotten.
