摘要
根据API 682标准的基本要求并结合自身设计经验,对炼油装置中离心泵密封的选型要点进行了总结,主要包括密封类别、型式、布置方式、冲洗方案的选择以及泵用干气密封的使用范围和注意事项,进而对炼油装置中高温热油泵、闪蒸烃泵、有毒有害类介质泵、常规工艺流程泵、高温热水泵、焦化切焦水泵、循环水泵及其他常温水泵、易结晶介质泵的密封选配方案进行了分析并提出了合理化建议。
In this article,in accordance with the fundamental requirements and combined with self-experiences in design,the author summarized the key points in selection of seals in centrifugal pump used in refining industry from aspects of seal kinds,seal forms,seal layout,cleaning scheme,and the applicable scope of dry gas seal and the notes in its use.Then the seal schemes selected for various pumps used in refineries,including high temperature oil pump,flash hydrocarbon pump,toxic and harmful liquid pump,conventional process pump,high temperature water pump,coke pump,circulating water pump,normal temperature water pump and crystallization liquid pump,were analyzed,and some appropriate proposals were presented.
