摘要 通过对某型600 MW电站锅炉给水泵进水端流场部分建立三维模型。在ANSYS12.0平台上采用CFX模块数值计算。研究结果表明:原型进水端出口处速度分布较不均匀,提出采用改变导流段分布和调整导流段角度这两种方式提升进水端水力性能。其中,采用调整导流段角度的方式进行优化设计在很大程度上提高出口处速度均匀性,从而提高泵体的整体水力性能。 The intake three-dimensional flow model of built. CFX is used to compute in the workbench ANSYS a 600 MW ultra-supercritical boiler feed-water pump is 12.0. The result shows outlet velocity is uniform. Two ways to improve hydraulic performance are provided that is different mode and angle of guide segment. And the method of different guide segment angle could deeply improve hydraulic performance of uhra-supercritical boiler feed-water pump.
