摘要
利用主泵振动监测系统得出的振动信号,文章结合田湾核电站俄供ΓΠH A-1391型主泵结构特点,对主泵径向止推轴承轴向振动缓慢升高的原因进行了分析,判断其上幅面板可能存在缺陷,提出了大修期间的检修建议和备件准备。在其后大修中进行检查,验证了振动分析的可靠性,为后续分析诊断提供了经验。
According to vibration signal of reactor coolant pump(RCP) vibration monitoring system and structure charactefisties of Tianwan nuclear power plant Russia ГЦ H A - 1391 type RCP, the cause of slowly rise of the RCP radial thrust bearing axial vibration is analyzed, and conclusion that upper panel may be flawed is drawn. Suggestions and preparations of spare parts are put forward to the overhaul maintenance. The reliability of vibration analysis is verified, and which provides the experience for subsequent analysis.
