摘要
水下舰艇武器推进泵的机械密封装置的工作压力波动、使用频率小,并要求可靠性高.根据这些使用要求和技术要求,对高压组合机械密封装置进行研究,分析了关键技术,给出结构设计方法、关键参数的选择以及设计计算方法,并对密封环受力变形问题采用有限元法分析.介绍了专门针对船用高压机械密封进行可靠性试验的试验装置,并对所设计的机械密封装置进行了试验,试验结果表明该密封装置能够很好地满足使用要求.
The mechanical seal utilized in submarine's weapon ejection pump works under fluctuant working pressure and is used in low frequency, and high reliability is indispensable. According to such requirements, this paper conducts analysis and design on high pressure assembled mechanical seal and its key techniques, and then presents the methods of its structure design, selection and calculation of its key parameters. Furthermore, the distortion of seal ring is analyzed by adopting finite element method. This paper involves the experiment device, applied to test reliability of submarine's high pressure mechanical seal, and then conducts test on the designed mechanical seal. The results indicate that such mechanical seal can fulfill the requirements commendably.
