Title:
タービンの回転軸の動的挙動を監視するための方法と装置
Document Type and Number:
Japanese Patent JP2009506261
Kind Code:
A
Abstract:
The invention relates to a method for monitoring the dynamic behavior, in particular of the oscillating behavior of a rotating shaft, the oscillation being detected by at least two sensors at defined different spatial position, the oscillating behavior in at least one preferred direction being determined from the oscillation. The invention also relates to a device for monitoring oscillating behavior in a rotary machine with rotable parts, having at least two sensors, a shaft and a computing unit, characterized in that the at least two sensors are positioned in a defined spatial position outside the shaft, detect measurement variables which characterize the oscillations and are connected to a computing unit for the transfer of data. The invention also relates to a gas turbine and a steam turbine that use a method and a device as per the invention.
