摘要
分析了450 kt/a合成氨装置合成气压缩机组的汽轮机在检修过程中出现高压段螺栓螺纹咬死现象的原因,根据汽轮机高压段螺栓拆装方法并结合实际检修情况,对拆卸工艺进行了优化。拆卸工艺优化后,实现了汽轮机高压段螺栓的顺畅、安全拆卸。
The causes of the bolt thread bite of the steam turbine high pressure section during the maintenance process of the synthetic gas compressor unit of 450 kt/a ammonia plant are analyzed. According to the disassembly method of the bolt in the steam turbine high pressure section, combined with the actual condition of maintenance, the disassembly process is optimized. After optimization, the smooth and safe disassembly of high pressure section bolts of steam turbine is realized.
