摘要(Abstract):

第三版的API 682标准已于2004年正式发布,与最新发行的ISO 21049完全相同。符合API 682标准的机械密封在石油、化工等工业大量应用。因此,对机械密封生产厂家有重要的指导作用。本文探讨分析了第三版API682做出的变更以及影响,并在端面材料、密封种类参数要求、密封腔体设计、连接管道设计、冲洗方案及设备等方面做出了改进和突破。
The third edition of API Standard 682 that is technically equivalent to the new ISO Draft International Standard 21049 has been published since 2004.The mechanical seals that meet the standard have found wide applications in petrochemical and chemical industries.Therefore,the standard was to serve as a guide to manufacturing seals based on what was working in actual services.The changes to the third edition of API Standard 682 were discussed and analyzed in this paper.It was seen in the edition that face materials,features of seal categories,design requirements to connections,standard flush plans and auxiliary hardware were improved and developed.
