离心泵蜗壳八个断面的设计研究
徐伟利(吉林省农业机械研究所)
提 要通过对离心泵蜗壳流道八个过水断面几何形状分析,建立了各过水断面几何尺寸的数学模型,采用计算机辅助设计,从而设计出优秀的泵蜗壳水力模型,提高了泵的效率指标,为泵蜗壳八个过水断面的设计提供了理论依据。
关键词 离心泵蜗壳 几何尺寸 计算公式 计算机辅助设计
Research and Design of Eight Prof iles
of Flow Duct in Spiral Casing of Centrifugal Pumps
Xu Wei2li( Jilin Provincial A gricultural Machinery Institute , Changchun)
Abstract The paper analysed geomet ry of eight profiles of flow duct , and established a mathe2 matic model of geomet ry demensions of profiles of flow duct in spiral casing of cent rifugal pumps The hydraulic model of spiral casing of pumps with good performance was designed by CAD It will improve pump efficiency and provide theoretical basis for designing eight profiles of flow duct in spiral casing of pump
Key words Spiral casing of cent rifugal pump Geomet ry demension Calculating formula CAD |
