摘要
针对提高KJS-Y降尘风机的除尘性能以便提高矿井下工作安全性,采用翼型设计方法和变环量设计方法对叶轮进行了理论优化,并建立优化前后降尘风机模型,利用流体力学软件FLUENT进行分析,得到其入口截面处压力、叶片表面静压分布和叶片周围涡流分布,将分析得到的结果相互比较。结果表明相对于初始叶轮,优化后的叶轮模型集流器入口截面负压提高了17.6%、动压提高了12.9%、全压提高了29.7%、全压效率提升了39.9%,各项性能指标都有较大提升。
In order to improve the working performance of KJS-Y dust-reducing fan.The impeller was optimized theoretically by means of isolated airfoil design method and variable loop design method,The model of dust-reducing fan before and after optimization is established.Fluid dynamics software FLUENT was used for analysis,The pressure distribution at the inlet section,the static pressure distribution on the blade surface and the vortex distribution around the blade were obtained.Compare the results of the analysis with each other,The results show that,Relative to the initial impeller.After optimization,the negative pressure,dynamic pressure,total pressure and efficiency of the inlet section of the impeller model collector are increased by 17.6%,12.9%,29.7%and 39.9%respectively,and all performance indexes are greatly improved.
