本期论文广场栏目中,布置两圈主螺栓的大直径氨合成塔筒体端部连接结构设计一文,针对氨合成塔筒体端部主螺栓超出GB 150.2-2011标准的最大规格,且加工使用十分困难的问题,提出了将主螺栓分为内外两圈布置在筒体端部上,由内外两圈主螺栓共同承受轴向载荷的方法,解决了强度计算问题。一种可拆式吊耳的设计、急冷器的设计及其特点探讨、大型导管架管线试压过程探讨、煤气预热器设计简述、立式搅拌设备带中间轴承搅拌轴的设
In the column of the paper of the thesis, the design of the connection structure of the end of the large-diameter ammonia synthesis tower with two main bolts is arranged. According to the maximum specification exceeding the standard of GB 150.2-2011 for the main bolt of the ammonia synthesis cylinder, Very difficult problem, put forward the main bolt is divided into two inside and outside the ring is arranged on the end of the cylinder, the inner and outer ring by two main bolts together to withstand axial load method to solve the problem of strength calculation. The design of a detachable lug, the design of chiller and its characteristics, the discussion of pressure test of large jacket pipelines, the design of gas preheater, the design of vertical gas mixing equipment with middle shaft
