离心压缩机干气密封放空管线缺陷分析与改造

Fault analysis and transformation of Dry Gas Seal vent pipeline used in centrifugal compressor

在介绍干气密封控制系统的基础上,结合天然气增压站因干气密封放空管线憋压造成的压缩机联锁停车实例,分析了干气密封放空管线在运行当中存在的隐患,并提出了整改措施。

Based on the introduction of the control system of dry gas seal,combined with the example of compressor interlock shutdown caused by the pressure holding of dry gas seal vent pipeline in a natural gas booster station,this paper analyzes the hidden dangers existing in the operation of dry gas seal vent pipeline,and puts forward the rectification measures.
