Abstract:

Feed water pump is one of important auxiliary equipments of steam turbine. In tuning up the feed pump of a steam turbine, over-vibration phenomena were found. In this paper, the vibration characteristic of the feed pump is analyzed carefully according to the vibration measurement data. It is found that the oil whip is the main cause of the over-vibration. The results provide a reference for tuning up and design of the feed pumps.

Key words: vibration and wave, turbine feed water pump, sound and vibration, oil whip
