高溫高壓反應釜頂蓋為標準橢圓型封頭,橢圓型封頭的長軸a=500mm,短軸b二250mm,封頭的名義厚度按照前面設計值S=16mm,按照無力矩理論給出頂蓋的經向和環向應力分布曲線。頂蓋應力理論分布曲線
高溫高壓反應釜由于頂蓋所受的內壓(0.7MPa)遠大于其外壓(0.1MPa),所以下面的分析只針對其承受內壓的工作狀態進行分析。
4.1頂蓋的理論應力分析
高溫高壓反應釜頂蓋為標準橢圓型封頭,橢圓型封頭的長軸a=500mm,短軸b二250mm,封頭的名義厚度按照前面設計值S=16mm,按照無力矩理論給出頂蓋的經向和環向應力分布曲線。
頂蓋應力理論分布曲線
從圖2中可以看出,在距中心大約425mm處,環向應力等于0,該處是環向應力由拉應力改變為壓應力的交界處,而頂蓋開人孔位置正經此處。以上應力狀況是針對不開孔的封頭的。對此處曲率變化較大部位進行開孔,必使應力復雜化。為此高溫高壓反應釜對按常規設計得出的頂蓋的壁厚提出了質疑。
