【Abstract】 In this paper, based on the combination of theory and practice ,the mechanisms of vibration malfunction for imported type 300MW turbogenerator sets is analyzed. The three bearing structure of generator and exciter is the main cause of question to initiate the large unbalance response for #6, #7 bearings and rubbing of sealed block . Finally in this paper author suggested the effective measure to control the vibration climbing and instability for #6, #7 bearings.更多还原
