利用节流孔板降低VVER低压安注泵振动

Reducing Low Pressure Injection Pump Vibration with Orifice in VVER

通过对田湾核电站3号机组调试过程中低压安注泵自由端振动高的原因分析和泵循环管线上节流孔板数量和孔径的计算优化,解决了低压安注泵体及其相关管线的振动问题,为后续核电机组低压安注系统管系设计提供重要的经验反馈和参考。

This paper analyzes the free end vibration of low-pressure injection pump, during the commissioning test on unit 3 of Tianwan Nuclear Power Plant.Through the quantity of orifice plates and optimization of aperture calculation, the pump and pipeline vibration problems are solved. It provides important empirical feedback and reference to the follow-up mechanical calculation for nuclear power unit pipeline.
