摘　　要：为了实现一般动设备的预知性检修,以某装置脱盐水、脱碳水和凝结水的输送泵群为例,进行了泵结构分析及建模,泵转子及轴承的受力分析以及轴承使用寿命计算。通过结合实例计算轴承寿命来定量估算同类型泵的轴承寿命,在轴承使用寿命后期,运用BH550等尖端科技仪器进行状态监测来判断轴承的磨损程度,为预知性检修提供依据。最终达到合理利用人力物力的目的。In order to realize predictive maintenance of general rotating equipment,took pump group of a equipment for example that can desalt water,decarburize water,and condensate water,analyzed and modeled structure of pump,analyzed stress of rotor and bearing of single-stage single-suction centrifugal pump and analyzed life expectancy calculation of centrifugal pump bearings.Combined with practical case,reckon up bearing life of the same type of pump.In the later period of bearing life,use the advanced monitoring instruments BH550 was used to judge the attrition rate of bearing through condition monitoring,which provided basis for predictive overhaul,ultimately,achieved the purpose of rational usage of human and material resources.
