【摘要】：本文以300MW核主泵双向推力轴承油密封副为研究对象,通过数值模拟分析、连续运转试验等方法,研究了各密封性能参数的相互影响以及密封面结构与密封性能的内在关系。通过对机械密封动、静环的受力变形分析,研究了密封端面变形与性能参数之间的联系。在考虑空化和不考虑空化两种情况下,分别对密封面进行了流场分析。阐述了影响泄漏量关键参数的取值方式。通过计算分析和连续运行试验验证,证明了该密封副结构变形小,应力分布合理,得出了泄漏量和开启力与密封副压差、动环端面流体浅槽深度的关系,密封泄漏量满足设备运行要求。
[Abstract]:In this paper, the effect of sealing performance parameters and the inherent relationship between sealing surface structure and sealing performance are studied by numerical simulation and continuous operation test, taking the 300MW nuclear main pump two-way thrust bearing oil seal pair as the research object. Based on the analysis of mechanical seal dynamic and static ring, the relationship between seal end face deformation and performance parameters is studied. Considering cavitation and not cavitation, the flow field of the sealing surface is analyzed. The method of determining the key parameters of the leakage is described. Through calculation, analysis and continuous operation test, it is proved that the structure has small deformation and reasonable stress distribution. The relationship between leakage amount and opening force, pressure difference of seal pair, shallow groove depth of fluid on moving ring end face is obtained. Sealing leakage to meet the operational requirements of the equipment.
