ISO 표준 기반 산업설비 진단 사례 연구

다국어 초록 (Multilingual Abstract)

In recent years, as the power demand of thermal power plants increases, the amount of fuel used increases, resulting in an increase in coal supply, which increases the operational burden on major components of the fuel system and increases the frequency of failures. Vibration analysis is one of the representative methods of nondestructive testing used to diagnose the failure of rotating machinery. This study is a case study related to conveyor system equipment diagnosis of thermal power plant. Especially, it is a case of diagnosing failure of gearbox, bearing, etc. of rotating equipment based on ISO standard. The vibration of the Conveyor Drive Motor was measured using ISO 20816. The review confirmed that the application of Class IV was necessary due to the flexible foundation structure. In addition, it was confirmed that the rotational speed component (29.9 Hz) was dominant in the case of the motor, and the rotational speed component (29.9 Hz) was also dominant in the reducer. Vibration caused by the gear defect frequency component has less energy transfer effect and the looseness phenomenon was observed. As a recommendation, it was found that the field balancing needs to be carried out on the motor side, and the stiffness reinforcement is necessary to remove the effect of looseness.
