【摘要】 根据混流泵叶轮的几何特征，给出了混流泵叶轮出口边的切割形式及其所对应的性能状况，并根据混流泵叶轮的切割规律，在 Ａｕｔｏ Ｃ Ａ Ｄ Ｒ１３．０ 环境下，用 Ａ Ｒ Ｘ语言和 Ｄ Ｃ Ｌ语言编写了一套混流泵叶轮相似切割选型系统。经使用与真机试验对照，证实所拟定的切割方式和性能预估策略是可靠的，选型系统的运行也是科学有效的。更多还原

【Abstract】 Based on the shape of the impeller of mixed p um p,cut\|off form and performance curve are given about outlet of impeller for mix ed pump.According to cut\|off rule of mixed\|pump and under AutoCADR13.0,a compu ter procedure is designed about impeller cut\|off with ARX and DCL languages.Com parison with the results of the prototype experiments,it is showed that the form of impeller cut\|off and the method of performance forestimated are reliable,an d the functions of the computer proceduer are scientific and efficient.更多还原
