引言叶轮设计是离心泵设计的关键问题之一。传统的设计方法(全由人工进行)计算、绘图的工作量大,设计工效低,精确度低,不能适应当前科技发展的需要。我们根据一元流动理论,经过数学处理,在本院的DJS—130机和CTS—Ⅰ绘图仪上实现电子计算机的辅助设计。由于DJS—130机容量小,这里没有建立数表和图表等的数据库及绘图的应用子程序库,而只对有关参数的计算和选定、轴面投影图的绘图及流道检查、平 Introduction Impeller design is one of the key issues in centrifugal pump design. Traditional design methods (all manual) calculation, the workload of drawing large, low efficiency design, low accuracy, can not meet the current needs of technological development. Based on the theory of unary mobile, we have mathematically implemented the computer-aided design of the DJS-130 and CTS-I plotters in our hospital. Due to the small capacity of the DJS-130, there is no database of sub-tables, charts, etc., and application subroutines are not available here. The calculation and selection of relevant parameters, the drawing of axial projections and the check of runners
