以核电站设备冷却水泵（以下简称设冷泵）为例，比过深入地分析了负动和润滑对轴承寿命和温度的影响，提出了润滑油选择比较有效的方法，对轴承的报警和停泵温度设定提供了依据。
Taking the cooling water pump of nuclear power plant equipment (hereinafter referred to as the cooling pump) as an example, the influence of negative and dynamic lubrication on bearing life and temperature is analyzed in detail. The method of selecting lubricating oil is more effective, Temperature settings provide the basis.
