ZHANG Shanpeng1, XING Xiuping21.Shandong Electric Power Research Institute. CAUSE ANALYSIS OF UNSTABLE VIBRATION ON BEARING NO.9 OF SUPERCRITICAL 660 MW UNIT AND DISPOSAL THEREOF[J]. Thermal power generation, 2010, 39(8): 51-53.DOI:
The phenomenon and characters in climbing and suddenly changing of vibration on bearing no.9 of unit no.5 after overhaul in the process of start-up at Huangdao Power Plant have been presented
especially the rapid changing of vibration
boasting certain typical and representative characters.The causes leading to climbing and suddenly changing of vibration have been analysed
and disposal measures
such as controlling the tightness of coupling bolts between generator and slip-ring within 1700~2000 kNm
and controlling the swaying at bearing neck no.9 within 0.05 mm
being put forward.After implementation
the shaft vibration under constant speed 3000 r/min
