摘 要:合成氨装置空气压缩机组经过富氧技术改造后,检修时发现压缩机高、低压缸封头和缸体均出现了不同程度的流体冲刷、氧化腐蚀现象。综合考虑,采用手工钨极氩弧焊方法,对冲刷、腐蚀部位进行堆焊修复,保证了压缩机能够按照检修进度正常开车运行。Air compressor used in synthetic ammonia plant after oxygen-enriched technology reformation was found during maintenance that the high and low cylinder head and the cylinder body were suffered from fluid scour and oxygen corrosion in differently level.Taking comprehensive consideration,the manual argon tungsten-arc welding method was taken to make surfacing weld to repair the scoured and corroded part,so as to ensure the schedule of maintenance and normal start-up.
