摘　　要：秦山第三核电厂1#机组3#主泵在启动和运行期间振动较大。为查找主泵振动大的原因,进行了4个方面主要参数的测量:旋转机械振动在线测量、主泵模态试验、主泵现场振动测量和主泵热位移测量。在分析现场测量数据的基础上,诊断出主泵振动大的根本原因,同时提出主泵振动处理的改造方案。方案实施后,振动有了大幅度降低,消除了长期困扰主泵振动的报警缺陷。The vibration of 3# primary pump of unit 1 in Qinshan NPP3 is serious during the start-up and operation. In order to find out the reasons for the vibration, the main parameters in four fields were measured rotating machinery vibration test, mode test, the vibration test and the heat displacement test of the primary pump. Based on the analysis of the measurement data, the root cause for the vibration of the primary pump is diagnosed, and the modification scheme is put forward. After the implementation of the modification scheme, the vibration is reduced greatly, and the alarm defect of the primary pump vibration has been eliminated.
