| Abstract: | Excessive vibration of low pressure rotor support bearing block is the common problem of Siemens 1 000 MW ultra-supercritical steam turbine generator units.Illustrated with a case of Unit 7 in Beilun Power Plant,this paper introduces the vibration characteristics that the unstable vibration of No.4 bearing and shaft is the reason for being unable to operate.Based on the experimental research and analysis,it proposes the solution which combines shaft system dynamic balance treatment with bearing block mainte... |
