1、精品好文档,推荐学习交流浮头式冷却器E-1401设计摘要该毕业设计题目为浮头式冷却器(即浮头式换热器)E-1401设计,源于工程实际。浮头式换热器是管壳式换热器中的一类,其管板一端固定在壳体与前端管箱之间,另一端(即浮头)可以在壳体中自由移动。由于管束的热膨胀不受壳体的约束,因此浮头式换热器不会产生较大的温差热应力,这样便避免了对换热器结构的损害。此外,浮头式换热器还便于拆卸、易于清洗,适用于壳体和管束温差较大或壳程介质易结垢的场合。因此在石油化工以及其他相关行业中得到了广泛的应用。该设计主要进行了换热
2、器结构的研究和各处强度的校核。根据所提供的设计条件,以及GB150-2011《压力容器》、GB151-1999《管壳式换热器》、《固定式压力容器安全技术监察规程》等标准确定出换热器各个零部件(管箱、封头、法兰、开孔接管、折流板、钩圈等)的具体方案,包括各处材料的选择,各零部件的基本结构,壁厚计算及强度校核,开孔补强计算,管板、法兰以及浮头钩圈的强度计算等。本设计历时3个月,共完成说明书一份,A1图纸5张,外文翻译一份。关键词:换热器浮头设计仅供学习与交流,如有侵权请联系网站删除谢谢16精品好文档,推荐学
