大型反应器管束组装方法

The Method of Bundle Assembly in a Large-scale Reactor

阐述了固定管板式板式热交换器穿管方法的分类定义及其利弊关系,针对大型反应器壳程主要元件的特点,考虑格栅、管板等元件尺寸精度控制,管束组装同轴度控制等制造难点,从管板与壳程筒体组焊、基准线标注、导向器安装、格栅组装、平台高度调整以及米字型穿管等方面介绍了盲穿换热管的组装方法。

The classification,definition and advantages and disadvantages of tube-through method for fixed tube heat exchanger are expounded.The blind-through heat exchanger tube assembly are introduced from aspects such as the assembling and welding of tube sheet and shell cylinder,datum line marking,guider installing,grille assembling,platform height adjusting,rice wrote in Chinese sharped tube-through method with consideration of difficult points including element dimension accuracy control of grille and tube sheet,coaxiality of tube bundle assemble in manufacture.
