摘要/Abstract

摘要：

某石化公司丁二烯装置的双螺杆压缩机是装置的关键机组，其安全经济运行水平直接影响装置的安全稳定生产。在历次检修过程中,压缩机出口侧密封多次泄漏。2024年7月检修后,压缩机出口侧密封漏量48 L/h，远超机械密封允许泄漏的标准（0.02 L/h）。由于油膜机械密封备件昂贵，单纯通过停车更换备件的常规维护策略，不但耗费巨大且无法从根本上解决机组的泄漏问题。针对以上问题对该设备的机械密封泄漏原因进行分析及制定处理方法。

Abstract:

The butadiene twin screw compressor of a petrochemical company is a critical unit that directly affects the safe and stable production of the unit. During previous maintenance processes, the seal on the compressor's outlet side has leaked multiple times. After the maintenance in July 2024, the leakage rate of the seal on the compressor's outlet side was approximately 48 L/h, far exceeding the allowable leakage standard for mechanical seal (0.02 L/h). Due to the high cost of oil film mechanical seal spare parts, the conventional maintenance strategy of simply replacing the spare parts during maintenance is not only expensive but also fails to fundamentally solve the leakage problem of the compressor unit. In response to the above problems, the reasons for the mechanical seal leakage of this equipment were analyzed, and some treatment methods were developed.

Key words: twin screw compressor, oil film mechanical seal, shaft seal leakage, solution
