Oil Whip Phenomena and Countermeasure on Steam Turbine in 350MW Load Thermal Power Plant

350MW급 화력 발전소 증기터빈의 오일 휩 현상 및 대책

There are several bearing systems at the large steam-turbines in thermal power plant. The bearing system is one of the most important parts of rotating machinery. The steam turbine vibrations mainly depend on the bearing oil and the shaft alignment condition. This paper describes on the steam turbine abnormal vibration due to the oil whip in terms of the shaft alignment in the thermal power plant.
