Analysis on Oil Whip of Steam Turbine

Oil whip, which is one of the typical types of steam turbine failure, may lead to large amplitude vibration of the rotor and even to catastrophic accident. In order to prevent and on-line eliminate the oil whip, researches on vibration of steam turbine caused by the oil whip and its characteristics have been elaborated from two respects of theory and experiment. The causes and the formation mechanism of the oil whip have been analyzed, and in certain conditions, a series of experiments for the oil whip on the rotor experiment rig have been made. Illustrating and summarizing the results of these experiments by change the rotor speed and the lubricant quantity. These researches on the oil whip could provide some theoretical bases for the practical work. Along with the expounded prevention measures of oil whip, some ideas on oil whip online elimination are put forward.
