基于AutoCAD的工业汽轮机热力平衡图动态绘制系统

Thermal equilibrium diagrams dynamic drawing system of industrial steam turbine based on AutoCAD

针对手工绘制汽轮机热力平衡图费时间、图形格式各异和通用性差等问题,开发了工业汽轮机热力平衡图的动态绘制系统。首先建立规范的图例库,包括部件图例、管道连线图例和文本图例,然后在Visual Studio 2005中进行程序编写,最后基于AutoCAD应用程序,实现工业汽轮机热力平衡图的动态绘制输出。研究结果表明,该绘制系统可以和热力设计软件无缝集成,绘制不同工况、不同机型机组的热力平衡图,操作简便、高效,制图规范正确,为设计人员提高工作效率提供了很好的开发工具。

Aiming at the problems that hand-drawing thermal equilibrium diagram for turbines is time-consuming,unfixed graphics formats and poor commonality,the dynamic drawing of industrial steam turbine thermal equilibrium diagram was developed.First of all,the standardized legend libraries were established,including components legends,line legends and text legends.Secondly,procedures were programmed in Visual Studio 2005.Last but not least,the dynamic drawing of industrial steam turbine thermal equilibrium diagram based on AutoCAD application was achieved.The results indicate that the dynamic drawing system can seamlessly integrate with thermal design software,and draw thermal equilibrium diagram of different conditions or different units.The manipulation is simple,efficient,and drawing specific,so it is a very good development tool to improve efficiency for designers.
