AbstractAbstract
[en] Amount of electricity which was produced from generator decided by control valve of turbine. Operating method of control valve have two modes. First operating method is partial arc admission, and second operating method is full arc admission. Especially, partial arc admission mode has an influence on alignment of turbine. In this paper, we had investigate abnormal vibration of turbine due to control valve

AbstractAbstract
[en] During the operation, central ventilation fan stopped when switch 'on' condition. When central ventilation fan disassemble, ten blades of fan fractured. We have searched cause of failure. We had modeling one of the fan blades and analysis with computer programs. Thus we have find that fracture of central ventilation fan blades is alternative stress and vibration at hub. In this paper, we have described cause of failure

AbstractAbstract
[en] Vibration of turbine is concerned with array of last moving blade at lower pressure turbine. When last moving blade at lower pressure turbine was replaced, we must consider mass unbalance problems of blades. If mass unbalance happened at rotor, it is impossible to operate turbine. In this paper, we have how to minimize the mass unbalance problems of last moving blade at lower pressure turbine

AbstractAbstract
[en] Oil supply system is one of the most important part of turbine. Lubricating oil of bearings supplied by oil pump. Failure of oil supply pump critical damaged parts of turbine, especially bearings. In this paper we have discussed the serious damage of turbine bearings due to failure of oil supply pump
