Special software development in selecting hydraulic model of axial flow pump

为选择到合适的轴流泵水力模型,基于轴流泵段性能与泵装置性能之间的关系,确定水力模型选择的方法与步骤,提高泵段模型与进、出水流道组成的泵装置效率。以南水北调工程水泵模型同台测试成果为主要的数据资料,采用Matlab结合Visual C++语言开发了选择轴流泵水力模型的专用软件,通过输入泵站扬程、流量数据,计算出满足基本要求的水力模型、原型泵的转速与叶轮直径以及原型泵的综合特性曲线。计算结果表明,该专用软件为比选水力模型建立了优秀的平台,在轴流泵站设计水泵选型中具有较高的应用价值。

There exist some relationships between the pump and the pump system. The method and procedure of selection of hydraulic model pump are presented. According to the above method, the efficiency of pump system is increased. The special software to select hydraulic model pump has been developed with Matlab and Visual C ＋ ＋ based on the data from the results of the Tianjin test. When the parameters of pumping station, the suitable hydraulic model pump, the rotating speed and the diameter of impeller of prototype pump are inputted, the curves of comprehensive characteristic will be obtained. The software has high value in the selection of axial flow pump.
