摘　　要：主要介绍核电主泵电机空载及一回路低压状态上推力瓦温度比下推力瓦高的问题原因分析,并以CPR1000主泵电机和华龙一号主泵电机实际运行数据为例进行解析,介绍了主泵电机的推力轴承结构、测温原理及其流场分析。This paper mainly introduces the reason why the temperature of the upper thrust pad is higher than that of the lower thrust pad in the no-load and low-voltage state of the main pump motor of nuclear power,analyzes taking the actual operation data of the main pump motor of CPR1000 and the main pump motor of Hualong No.1 as an example and introduces the thrust bearing structure,temperature measuring principle and flow field analysis of the main pump motor.
