摘要
本系统用于自动绘制换热器管板布管图．系统采用混合编程的方法，建立了三个模块，（计算模块、绘图模块、菜单模块），且使三者成功地融于ＡｕｔｏＣＡＤ环境下．在给定基本参数（换热器公称直径ＤＮ，中心排管数Ｎｃ，布管数ｎ，管程数Ｎ和拉杆数Ｎ１）条件下，自动绘出布管图，该系统已在８０２８６和８０３８６ＡＴ／ＸＴ上调试成功，为换热器的管板设计提供了布管基础．
This system is to be used for the Auto-drawing the distribution figures of heat exchanger's tubes. Mixedly programed, the system sets up three models (the computing model, the drawing model and the menu model) and has successfully put these models in Auto CAD system. When some basic data (the diameter of heat exchanger DN, the number of tubes in the centre Nc, The number of tubes n, the Path number of tubes N and the number of rods n) are given, it can diaw the figure of tubes' distribution. The system have passed on computer 80386 & 80286 AT/XT and drawen some figure. It has laid a foundation for the distribution of tubes when designing heat exchanger's tube plate.
