RDI’s Motion AmplificationTM, finding a better way to detect premature failures!

RESULTS

  • Captured Motion AmplificationTM (MA) videos and diagnosed the fault in the field within 1 hour
  • Visualisation of the root cause (coupling wear, loose hold down bolts and failed welds) of the high axial vibration that had been difficult to identify with traditional vibration analysis techniques
  • Remediation work during a low load period reduced the high axial vibration at the fan drive end bearing by more than 70%
  • Solution implemented at a time when substantial

“Motion Amplification technology allowed us to identify movement in the bearing pedestal…With this knowledge and by calculating the predicted failure date the fan was proactively removed from service to repair during low load periods.”

PROBLEM

There are two Induced Draft (ID) Fans critical to the operation of each 700+ megawatt turbo generator at this Power Station. Staff had been monitoring a steady increase in axial vibration at the Fan Drive End Bearing of one of the two ID Fans for Unit 3 turbo generator. The axial vibration amplitude had increased from 1.75 mm/sec RMS to 8.5 mm/sec RMS over a 2-month period. The vibration analysts were finding it difficult to identify the root cause of the increasing trend and noise coming from the coupling through traditional vibration analysis techniques. Historically this type of fault would have been left to run to failure resulting in a $70k/hour loss of generating revenue for the business.

SOLUTION

In alliance with the generator’s engineering team a leading global consulting company, ALS Industrial, applied RDI’s Motion AmplificationTM (MA) technology to help solve the emerging ID Fan problem. From arriving at the location of the ID Fan in the power station, setting up the video camera and acquiring several MA videos it took less than one hour. This hour included the time to analyse the results all of which was done in the field. The MA videos helped identify several problems including: coupling wear and movement on the shaft, bearing housing hold down bolt looseness, frame pedestal bolt looseness and cracked welds between the bearing housing spacer block and fan drive bearing pedestal. During a low load period and a 300MW restriction the coupling, bearing housing and bearing pedestal issues identified were rectified. When the fan was returned to service the high axial motion and vibration had been reduced by more than 70% and was now 0.6 mm/sec RMS. The solution to this problem was expedited and better understood through the application of RDI’s Motion AmplificationTM technology.

Another update for IRIS M Motion Amplification

By | Latest News | No Comments

Dear IRIS M Motion Amplification user,

All IRIS M MA users are receiving this update notification.  During the installation process of the new update the license management application will check the status of your license to ensure that you are entitled to the new update.  Entitlement is guaranteed within the initial 12 month period following your IRIS M MA system purchase or with a current RDI Technologies Maintenance Agreement.

Please refer to the “IRIS M new release history” attached for a summary of all the updates over the past 18 months.

RDI Technologies is excited to announce a new update for the Iris M.  This software update brings an exciting set of new features to the product.  These features are the most requested by our users.

Some notable features include:

  • Calculate Spectrum from Portion of Waveform – Calculate spectral data from a specific part of the available waveform.  This is accomplished graphically from the waveform plot, and calculated spectra are updated dynamically as the region over which they are calculated is modified.
  • Bulk Filtering – Using Motion Explorer, copy the filters from one recording and apply them to one or more recordings.  This means that you only have to set up the filters once if applying the same filters to multiple recordings on the same asset.
  • Spectrum Harmonic Cursor – Harmonic cursors are now supported in spectrum plots.  This allows harmonic frequency content to be more quickly recognized.
  • Autoscale Across Plots – Autoscaling the amplitude axis across plots of the same type (e.g. spectrum or waveform plots) allows quick recognition of relative amplitude values.

There are 2 software configurations.

Acquisition System (RDI Acquisition and Motion Amplification) – includes both Acquisition and Motion Amplification software.  This will need to be installed on the dedicated tablet/laptop for field use with the Iris M system

Stand Alone – This is the Motion Amplification analysis software only.  This is a single license and can be installed on another computer (laptop or desktop) for office analysis of the captured data.

NEW IRIS M VERSION 2.0  GAME CHANGING FEATURE: FREQUENCY BASED FILTERING

By | Latest News | No Comments

NEW IRIS M VERSION 2.0 GAME CHANGING FEATURE: FREQUENCY BASED FILTERING

This new feature will revolutionise the way you see motion.

Check out the video to see how

The latest update to RDI Technologies flagship product, the Iris M, allows users to isolate individual frequencies in the Motion Amplified video data. This incredibly powerful new feature is done graphically via a colour-coded spectrum. Also, combinations of filters can be applied to isolate multiple frequencies.

To apply the filter, the user simply indicates a region of interest (ROI) within the captured video which in turn, produces a spectrum. Then simple manipulation of the spectrum with the cursor allows setting of the filter cut-off frequency.

Sounds too simple to be true?

Welcome to the world of IRIS M where ‘Seeing is Believing’…

In addition to the filter update, Iris M Version 2.0 includes the following valuable new features:

  • Orbit Plots – Displays motions at a location in the data on an X-Y plot.
  • Simpler ROI drawing – Drawing an ROI with the mouse has been updated to make displacement measurements more intuitive.
  • Record data sets based on time instead of number of frames.
  • Addition of CPM units.
  • Ability to export time waveforms to .csv files.
