摘　　要：调查了核主泵电机轴承结构及材质,分析了核主泵电机在用润滑油的理化指标、元素含量及磨损颗粒,探讨了核主泵电机润滑油铅含量偏高的原因。结果表明:在本案例中,核主泵电机润滑油铅含量升高与润滑油本身以及电机轴承的机械磨损无关,可能来源于电化学腐蚀电机轴承或者由于加油工艺偏离,换热器、密封等破损导致的外界污染。Structure and material of Nuclear Main pump motor bearing was investigated, in-service lubricant of nuclear main pump motor was analyzed. Source of lead in nuclear main pump motor lubricant was discussed. The result shows: in this case, lead in nuclear main pump motor lubricant is not coming from new lubricant and/or wear metals, it might come from electro-corrosion and/or caused by out-control lubricant-adding, damage of heat- exchange or seals etc.
