4对某炼油厂高温服役的烟气管道进行了数值模拟分析,得到管道服役时的应力、位移和力矩分布图,讨论了导致该管道产生较大变形及力矩的原因,并由此提出了两个改进的技术方案,在分析比较模拟计算结果的基础上确定了最优方案。
By an analysis of resistance change and regulating character of gas exhaust ductwork in the condition of cell-machining,gets the way to regulate the damper at the exit of the cell.
通过对铝电解槽排烟管道系统阻力变化和调节特性的分析,得出了槽盖板打开时电解槽出口管路阀门调节的方案,并提出一种提高电解槽排烟管道调节性能的改进措施:通过调整排烟管道的尺寸,使电解槽盖板打开时能自动保持其原有阻力损失基本不变,减少了调节工作量和调节误差。
