摘　　要：针对氮气压缩机轴封泄漏问题进行排查,发现是由轴封系统设计缺陷引起,通过扩大压缩机上缸体隔离气进气孔和密封气漏气孔尺寸,并重新配置漏气管线,增大漏气管和漏气放空总管,解决了泄漏问题,保障了机组稳定运行。Searching the shaft seal leakage in nitrogen compressor,we found that the leakage was caused by the design defect.By expanding the compressor cylinder isolation air inlet and the sealing air leakage hole size,reconfiguring the leakage pipeline,and enlarging the leakage pipe and the venting header,the leakage problem was solved,and the stable operation of the compressor was ensured.
