Failure Prediction and Health Management of Drum Filter Actuating Device in Nuclear Power Plant

This article focuses on the failure prediction and health management of drum filter actuating device in nuclear power plant. Firstly, by the analysis of drum filter actuating device’s key feature, mechanical structure and main failure form, it found that equipment maintenance trend was transitioning from shutdown maintenance or periodic inspection to real-time online condition monitoring and fault analysis. Secondly, based on the actual situation of the fault concentrate on the medium/high speed first stage reducer, especially the bearing fault, this paper mainly introduced the application cases of drum filter failure prediction and health management, the validity and accuracy of diagnostic conclusions were verified by the equipment maintenance. This case provides practical guidance to implement predictive maintenance and condition maintenance, which provides strong guarantee for the stable operation and contributes to the goal of maximizing the efficiency of the plant.
