The Improvement of Storage Method for Spare Part of Turbine Bearing in Power Plants

High quality of turbine babbit bearing has to be maintained for smooth operation of power plants. So in the research center of the Korea Electric Power Company, Ultrasonic testing has been peformed on the spare part of babbit bearing during past ten years. Since separation between babbit bearing and base metal was seen for most of the bearings in stock, investigation has begun in order to see the effect on temperature and humidity variation of the separation, and thus searching for the optimum storage method.
