中文摘要：

为了提高泵站水机选型的效率与精度,利用Visual Basic 6.0对AUTO CAD 2008进行二次开发,设计出一套多用途的参数化水泵选型程序。结合泗阳二站水泵选型的工程实践,选择了两副适合的水力模型,并利用ANSYS-CFX对选择的两副水力模型进行全流场三维数值计算。结果表明,通过水泵选型程序选择的水力模型能够满足泗阳二站的工程需求,通过CFD数值模拟进一步确定了泗阳二站选用的水力模型。

英文摘要：

In order to improve the efficiency and accuracy of pump selection, the Visual Basic 6.0 was used to develop the AUTO CAD 2008 for secondary development, which designed a multipurpose parametric pump selection program. Combined with the engineering practice of pump selection in Siyang second station, two hydraulic models were selected, using ANSYS-CFX to do the three-dimension numerical calculation of the whole flow field. The results showed that the hydraulic model selected by pump selection program can meet the engineering requirements of Siyang second station. The hydraulic model was further confirmed by CFD numerical simulation.
