监测尤其是燃气或蒸汽轮机的旋转轴动态特性的方法和装置

Abstract

本发明涉及一种监测旋转轴(25)动态特性尤其振动特性的方法,其中,通过至少两个传感器(10、12)在规定的不同空间位置检测振动,以及,根据振动确定至少一个优先方向的振动特性。本发明还涉及一种监测在具有可旋转部分的可旋转机器(40)内振动特性的装置,它有至少两个传感器(10、12)、一根轴(25)和一个计算装置,其特征为,所述至两少个传感器(10、12)定位在轴(25)外部规定的空间位置,以及,传感器检测表征振动的测量参数并为了传输数据与计算装置(70)连接。此外,本发明涉及一种使用按本发明的方法和装置的燃气轮机和汽轮机。
The invention relates to a method for monitoring the dynamic behaviour, in particular the oscillating behaviour, of a rotating shaft (25), the oscillation being detected by at least two sensors (10,12) at defined different spatial positions, the oscillation behaviour in at least one preferred direction being determined from the oscillation. The invention also relates to a device for monitoring oscillating behaviour in a rotary machine (40) with rotatable parts, having at least two sensors (10,12), a shaft (25) and a computing unit, characterised in that the at least two sensors (10,12) are positioned in a defined spatial position outside the shaft (25), detect measurement variables which characterise the oscillations and are connected to a computing unit (70) 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.
