Application of AutoCAD and Excel in Hydraulic Design of Centrifugal Pump

For a centrifugal pump,AutoCAD and Excel software are used to confirm the main parameters and structure scheme,draw the blade contour,design the sections of spiral case,draw the characteristic curve,the regression analysis to experimental data and plot the 2D projection drawing and so on.The realization methods of design process are discussed.These methods are very significant to reduce the labor intensity of design,increase the design precision, shorten the design periods,lower the cost and improve the capability of product.
