摘　　要：本文首先对轻水反应堆的核主泵类型进行了分析,针对其核主泵的主要应用形式——轴封型核主泵进行了端面密封类型的介绍,再从可靠性的观点出发,分析了端面密封中核心零件密封环的失效形式。在分析的基础上,从可靠性角度分析了端面密封环的不同形式的失效模式以及定性可靠性指标。为开展和主泵的端面密封形式选择。This article firstly introduces several types of the Light-water nuclear reactor primary pump type and its shaft seal. Then from the viewpoint of reliability, the failure mode of sealing ring, which is one of the core parts in face seal is analyzed. On the basis of the analysis, from the point of view of reliability the failure different mode and qualitative reliability index of face seal ring are calculated. The article provides references on the selection of the mechanical face seal form in designing nuclear coolant pump.
