反应堆主循环泵故障诊断

FAULT DIAGNOSIS FOR THE PRIMARY LOOP PUMP OF REACTOR

应用振动监测技术，通过参数分析、信号分析及谱分析，对反应堆一循环在役主泵的故障进行了分析诊断。诊断结果与解体结果完全一致。

Fault diagnosis of main pump of the primary system of reactor which runs at normal condition is studied by the vibration, analysis technique. By means of picking up vibration signals of the pump,using the parameter method, the probability density function, correlation analysis and spectrum analysis etc, the fault type of the pump and corresponding reasons are diagnosed and analysed.
