摘要: 田湾核电站3、4号机组电动主给水泵在调试过程中发生二倍频振动现象,经模态测试发现二倍频与泵本体三阶固有频率相近;通过对泵本体底座加固调频,提高了泵本体三阶固有频率;经泵组带载试转,泵组轴承座振动明显降低,加固调频取得较好的效果。

Abstract: The main feedwater pump frequency-doubled vibration occurred in Tianwan NPP units 3 and 4 in the process of commissioning. The frequency-doubled is approximately equal to the three times frequency of the pump structure according to the result of modal test. The three times frequency of the pump structure is increased by reinforcing the pedestal of the main feedwater pump. According to the test result, the vibration of the bearing pedestal is reduced obviously. The reinforcement results in good effect.
