Abstract

Abstract

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.
