일체형 삼점지지 고압 LNG 2차 펌프 rotor의 1차 mode 특성을 고려한 Balancing 벡터선도 연구

다국어 초록 (Multilingual Abstract)

Balancing of rotating machinery can determines the life of the machine. before further damage occurs. The subject of this paper is a secondary high-pressure LNG Pump. This pump has a long shaft and integral type of rotor. Also, the shaft has three support points. This shape has difficulty correcting the unbalance using the existing two-plane balancing. Therefore balancing technology development is required. It simulated a high-pressure LNG Pump with Rotor and Shaft shape of the subject integrated using Pilot Rotor as previous studies to determine the optimal balancing rpm of the Lab Scale Shaft. By carrying out balancing at each rpm, we compared the amplitude, drew the graph and compared every aspect resulted from balancing at each rpm. Then, we check which rpm the most advantageous balancing occurs at.
