【摘要】 为了完成轴流泵站进水流道的计算机辅助设计(CAD)软件的研制,将轴流泵站进水流道原人工设计过程进行数解,并建立相应的数学模型,提出用“控制断面”设计进水流道内流速沿程变化曲线(V～L曲线)的方法,并利用AutoCAD作为图形支撑软件,使进水流道的设计与绘图一体化。更多还原

【Abstract】 The hand calculation design process of the inlet passage of an axial pumping station has been transformed to a mathematical analytic process and a corresponding mathematical model has been established for completing a study of computer auxiliary design(CAD) software of the inlet passage of an axial flow pumping station. The design and drawing of the inlet passage can be completed simultaneously by using"control section" to design the velocity change curve along longitudinal section(V～L curve) in the inlet passage and by using the AutoCAD as the drawing support software.更多还原
