摘要： 目前泵设计系统普遍依赖商用CAD软件的二次开发,容易受到制约.为此,利用OpenCASCADE相关建模函数和Qt构建的人机交互界面开发了拥有自主知识产权的三维轴流泵叶轮设计系统,只需输入轴流泵的设计参数,便可得到合适的轴流泵叶轮几何造型.采用该系统设计比转速为869的轴流泵叶轮,并对其进行流场仿真验证,同时对比CFturbo软件的设计结果.结果表明,该系统无软件环境限制,设计步骤更贴合国内设计习惯,可以满足扬程和效率的设计要求,为其他类型的泵参数化设计提供了借鉴.

Abstract: At present, pump design systems generally rely on the secondary development of commercial CAD software, which is easily restricted. Therefore, a three-dimensional design system of axial flow pump impeller with independent intellectual property rights is developed based on related modeling functions of OpenCASCADE and the human-computer interaction interface constructed by Qt. Designers only need to input the design parameters of the axial flow pump to get the appropriate geometric shape of the axial flow pump impeller. An axial flow pump impeller with the specific speed of 869 was designed and verified by flow field simulation. Compared with the design result of CFturbo software, the results show that there is no software environment restriction in the system and the design steps are more suitable with the domestic design habits, which can meet the design requirements of head and efficiency, and provide a reference for parametric design of other types pump.

Key words: OpenCASCADE, axial flow pump impeller, Qt, computer aided design, parametric design
