| Abstract: | One bearing pad burned accident arise from lacking of oil,because the two lubrication oil pumps can not normally supply the oil at the same time during the 135MW turbine in idling state.After investigation of the accident,the oil pump problem was analyzed and concluded.Burned bearing pad was checked and measured,then the new pas was changed.When all the installation process,rotor turning,pad installation,oil system check,gland seal clearance check,rotor fixation was completed,the turbine wad started up and ... |
