介绍了德国BORSIG公司生产的 43 0 0kW氢氮压缩机 (型号为BX45 80 / 45 3 )。通过分析压缩机K2 、K4列高压段填料频繁外漏影响其长周期稳定运行的原因 ,对压缩机填料盒注油位置、填料材质、密封方式、填料盒结构几个方面加以改进。改造后使填料密封性能、运转周期、故障率、经济性等重要指标远远优于原始设计值 ,高压段填料连续运行创下 2 0 3天的好成绩 ,取得了较好的经济效益和社会效益。
The 4300kW Hydrogen Nitrogen Compressor (Model BX45 80/45 3) produced by Germany Borsig Company was introduced. By analyzing the reasons that the frequent leakage of high-pressure section packing of compressors K2 and K4 affect the long-term stable operation, the filling position, packing material, sealing mode and stuffing box structure of the compressor packing box are improved. The important indexes such as sealing performance, operating cycle, failure rate and economy of the packing are far better than the original design values after the transformation. The continuous operation of high-pressure section packing set a good result of 203 days and made good economic and social benefits .
