Effect of Dip Angle of Orifice Plate in the Flow Field of High-speed Centrifugal Pump

  • 摘要: 为了更深入的研究孔板形式对高速离心泵进口段回流漩涡的影响,提出改变孔板前后倾角大小的方法,主要设计了25种不同倾角孔板的组合方案,利用电脑模拟软件ANSYS-CFX对某一高速离心泵进行全流场的数值模拟分析,从中选取了对高速离心泵水力性能提高较大的3种倾角方案,对比分析高速离心泵的整体的流线和进口段的速度矢量变化情况,诱导轮叶轮压力和内部流场的影响,并对不同倾角孔板的性能曲线进行分析。综合对比分析为:-20°/10°型孔板能较好的改善进口段的回流漩涡,抑制诱导轮内部的回旋流,对高速离心泵的水力性能有很大提高。
