The data acquisition system on vibration evaluation and predictive maintenance for cooling water pumps system in TPS

The purpose of this paper is evaluating vibration status for cooling water pump system in TPS. The utility systems operate continuously since TPS commission in 2014. The predictive maintenance based on vibration level and spectrum became more important, especially for those unstoppable operate water pump systems. The vibration monitoring system started to construct in 2017 and upgraded in 2023. After vibration test over several months and years, some components of the cooling water pumps found abrasion and mismatched. The recorded data showed vibration level increase irregularly over ISO 10816 standard. The spectrum showed the detail status in the pump system. The cooling water pump systems repaired and maintained base on vibration evaluation after vibration evaluation. The utility systems could prevent malfunction at least over one month through regular vibration inspection and daily data acquisition. The data acquisition system for pump systems on vibration evaluation provided the predictive maintenance enough time to solve the problem and avoid system suddenly shutdown.
