System and method for detection and non-transient computer readable storage medium

Abstract

The invention provides a system and method for detection and a non-transient computer readable storage medium. In one example embodiment, a fluid induced instability detection system is provided thatmonitors various vibration characteristics of a turbo-machine, collects vibration data in real-time, and uses the vibration data to detect and analyze changes in various operating parameters such as vibration, speed, and loading conditions, and to provide an indication of a vibration anomaly and / or potential operational risk in one or more components of the turbo-machine. The vibration data can beparticularly associated with certain components that are directly or indirectly impacted by a modification in process fluid flow characteristics or lubrication oil flow characteristics in the turbo-machine due to various reasons such as process fluid flow disturbances, lubricating oil flow disturbances, and / or a change in turbo-machine operational parameters. The fluid induced instability detection system detects abnormalities in the vibration data and provides an indication of one or more potential faults in the turbo-machine.

Description

technical field [0001] The present invention relates to turbomachinery and, more particularly, to systems and methods for detecting fluid induced instability conditions in turbomachinery. Background technique [0002] Turbomachines are machines that operate based on the interaction between fluids and machine parts. An example of a turbomachine is a gas turbine that uses a fluid (heated gas) to move the blades of a rotor assembly. Another example is a compressor that uses elements such as pistons to compress a fluid (air-gas mixture). Most of these machines are quite complex in construction and comprise a large number of parts. Like any component, especially a moving part that is exposed to constant wear or breakage, the various components of a turbomachine can malfunction which can lead to damage to the turbomachine. Accordingly, various types of monitoring devices and / or sensor devices are used to continuously monitor the status of various components of turbomachinery an...

AI Technical Summary

Problems solved by technology

[0003] Some faults are relatively easy to monitor and detect, while some other faults are somewhat subtle in nature and difficult to identify

For example, barely noticeable low frequency vibrations in components of a turbomachinery can lead to much larger magnitude vibrations at resonant frequencies and sudden severe damage

Some other failure such as a slight change in the nature of the thermal flow can raise the temperature of the component beyond operable limits and cause the component to fail
