Seal Reconstruction of Hydrogen Centrifugal Compressor

介绍了某石化用双端面干气密封替代浮环密封的原因及应用情况。改造后的运行效果表明该干气密封性能稳定、运行可靠、泄漏量小、能耗较低,经济效益显著。

The reason and the application of centrifugal compressor in tianjin petrochemical was introduced, which used the dry gas with the double end surface instead of floating ring seal. The movement effect indicates the sealing property was stable, the movement is reliable, leak is small, the energy consumption is lower, the economic efficiency was remarkable.
