摘　　要：为了得到CAP1400堆型主泵在提速升温过程中最高限制转速的设定方法,结合泵的第三相似定律和量纲分析,推导出轴向力和功率均不超过正常工作点的转速设定方法。参照主泵正常工作下的参数,求得AP1000和CAP1400主泵在启动过程中的最高转速设定值,其中AP1000主泵的计算值为87.5%n_0,略低于实际运行的设定值88%n_0。采用实验验证的数值计算方法对自主设计的主泵水力模型在不同设定方法下的轴向力和径向力进行计算。结果表明:参照轴向力的设定方法计算得到的轴向力小于正常工作值,与理论结果相符。In order to get the maximum speed setting standard during the temperature-rise period of CAP1400 reactor coolant pump which rated speed was 1500rpm, the third similarity law and dimensional analysis were used to derive the setting formula of rotation speed which guaranteed that the axial force and power did not exceed the value of normal operating point. The maximum speed of AP1000 and CAP1400 were obtained according the parameters of the normal operating point, and the calculated value of AP1000 was 87.5% rated speed, which was corresponded to the current maximum speed setting of AP1000. The validated numerical computation of the self-designed RCP hydraulic model was carried out to verify the axial and radial force in different settings. The results show that the relation of axial force conforms to the theory when the maximum speed was set to ensure the safety of the axial force. The setting formula ofthe rotation speed which guaranteed both axial force and power can be used to set the maximum speed during startup process of CAP1400 reactor coolant pump.
