摘要
裂解气压缩机是乙烯装置的核心设备,近年来多选用干气密封作为机组的轴封。从旋转方向、配置方式和隔离密封等方面,对该机组干气密封的选型进行了分析,并提出了相应的对策。同时,对影响干气密封使用寿命的盘车系统、空气运转、密封气源等因素进行了讨论,给出了建议。
harge gas compressor is the core equipment of ethylene plants.In recent years,dry gas seal has always been used as its shaft seal. From rotary direction,configuration mode and separation seal,this article analyses the selection of dry gas seal and proposes the corresponding countermeasures.Meanwhile,it discusses the influencing factors of the service life of dry gas seal,including shaft turning gear system,air operation and seal gas sources and presents some corresponding suggestions.
