How do you decide which condition monitoring technologies
to use?
There are many condition monitoring technologies that we
could employ. And within each technology there are sub-technologies. For
example, within vibration analysis we can use high frequency analysis, spectrum
analysis, time waveform analysis and phase analysis. Within each sub technology
there are settings we must select. For example, we must set the frequency range
when collecting spectra. But which technologies should we use? Which settings
are correct? The best way to make those decisions is by understanding the failure
modes of the equipment.
If you understand what leads to failure, and what is likely
to fail, you can select the most appropriate technologies and settings. You may
argue that that is an obvious statement to make. You are probably not using
vibration analysis on your steam traps… But after 30 years of experience in
vibration analysis, it is common to see that fault conditions a totally missed
because of the misapplication the technology.
It is not necessary to perform a full RCM (reliability
centered maintenance) or FMEA (failure modes effects analysis) to make this
determination. A so-called “accelerated RCM” is sufficient to ensure
that you make the right decisions.
