Parametric Design of New Type Upstream Pumping Mechanical Face Seal

参数化建模是上游泵送机械密封型槽结构设计和优化的有效保障。本文通过对型槽结构的分析提出了一种新型螺旋线与圆弧组合的上游泵送机械密封端面型槽结构,并基于CAD/AutoLISP开发了参数化建模设计软件程序。程序能够实现与GAMBIT/FLUENT等分析软件的快速对接,提高上游泵送机械密封端面型槽结构优化的效率,其方便功能扩展的程序开放性,也为上游泵送机械密封其他新型组合型槽的开发提供了技术支持。

Parametric modeling is an effective measure to optimize spiral groove upstream pumping mechanical seal. The geometric parameters are analyzed for introducing combined spiral - curving groove upstream pumping mechanical seal, and then program of parametric design is developed by CAD/AutoLISP. This kind of program is used to fast contact with fluid analysis software GAMBIT/FLUENT for efficient geometry optimization. It make the system extend easily, providing technical support for developing other new type combined groove upstream pumping mechanical seal.
