【Abstract】 Througth test of unstable vibration of mediumpressure rotor of many 300MW steam turbines manufactured by ALSTOMBeizhong Inc., it is considered that the cause leading to the said unstable vibration to be collision and wearout between the mediumpressure rotor and the static part. Combining with structure features of the units, measures for controlling and preventing the movable and static parts from collision and wearout have been suggested.更多还原
