SDT Ultrasound saves production losses by inspecting vital steam delivery system

Since 1999, Adam De Gioia has been a fitter and turner working in a range of different industries from water/wastewater, pharmaceutical, hydraulics, food manufacturing, mining and oil & gas.

Starting his own company; ‘Final Drive Engineering Services’ in 2014, Adam soon partnered with a respected OEM of hydraulic components. It was here that he developed a passion for steam delivery systems and quickly became the ‘go to guy’ for repair work.

In recent years, he has been contracting to a well-known food manufacturing facility where he carries out offline maintenance. Over time he witnessed the degradation of their steam system which resulted in issues in the *CIP (clean-in-place) system.

Adam quoted – ‘Unfortunately, it’s kind of ‘Out of sight, Out of mind’, and only repaired when completely failed’.

To paint a picture, there are approx. 30 steam traps of differing types around the site. They are all critical in terms of pasteurizer and CIP performance. If one trap was to fail, multiple lines and holding tanks would be disrupted and production would cease until repairs were carried out.

Steam Trap with cloudy sight check
Steam Trap with no sight check. How do you know it's working?

Seeing the cost of production losses mounting on his customer, Adam knew he’d have to take a proactive approach.

Online research yielded numerous hits on steam system protection hardware using the SDT Ultrasound range. A meeting was organised with GVS rep Peter Haines at GVS HQ in Newcastle. In 1 hour they covered the basics of ultrasound, how Ultrasound inspection has numerous applications and finished with a focus on Steam Traps.

Adam recognized the benefits, purchased the SDT ULTRAChecker and put it to work the very next night.

Here are Adam’s words about his first experience with SDT’s equipment;

‘The 1st trap I tested had a very cloudy sight check. Using the audio and Histogram (bar graph) feature (on the ULTRAChecker) I quickly determined that it had failed. The 2nd trap had no sight glass on the check valve, and again through the earmuffs, the constant sound indicated yet another failed trap. 2 from 2.

‘The Engineering team are excited by the results. We can now identify steam issues and get on top of it early.’

ULTRAChecker used on functioning Steam Trap. The Histogram (bar graph) shows the fluctuation of when it is open and closed. Simple.

BUT Adam didn’t stop there.

Seeing how effective using a precision Ultrasound inspection device was, he turned to other areas of the plant.

He then went on to identify issues with:

  • condensate return pump
  • auto blow down on one of the boilers
  • hydraulic circuits
  • air leaks on the trucks air system.

In future, Adam will also aim to participate in ‘Live Online Level One’ (LOLO) Ultrasound course to further expand his knowledge and monitor other areas of plant.

GVS love these examples of our ability to supply a solution to a client with a challenging problem.

Thanks very much to Adam for sharing your story of success working with us!

POOR LUBRICATION: What ‘data’ are Lubrication Technicians using to grease?

Stories are great. Humans thrive on stories. Being able to hear and then re-tell stories is what sets humanity apart from other living creatures.

Weird side note: some humans can hear and re-tell the stories of non-living things like; machines!

For example, the below data (sent to us by a customer) would look confusing to most people on the planet. But, in that data lies a story waiting to be told…

This data tells the trained eye that ‘raised acceleration and noise floor in higher frequency spectrum’* was beginning to be a significant problem for this motor DE (drive end) bearing.

But, the conclusion of the story is that… the high frequency acceleration just magically disappeared…

Or is there another story to tell?

Recently, this customer took delivery of 4 x SDT LUBECheckers from GVS.

So, when given the work; grease the bearing, with the aid of the LUBECheckers the lubrication technician was able to leave the asset in an ‘optimal lubricated state’.

This data tells us that; through investment in technology, a machine bearing was clearly saved from further damage

This story is a success story. And this success story comes from 1 x bearing on 1 x electric motor…

This customer works in one of the largest mines in Australia. So, now armed with SDT Ultrasound, they can multiply that success story by how many bearings they have across the facility.

Good news stories make you feel warm and fuzzy… 🙂

Get in touch with GVS to learn how easy it is to use and deploy LUBExpert and LUBEChecker at your facility so you can tell a lot more success stories.

Create a Compressed Air Leak Management Program with SDT. It’s EASY

Why We Ignore Leaks
Compressed air is a misunderstood utility. As such, it tends to be misused and even abused. Leaks continue to be the biggest problem; often overlooked because they are difficult to detect, don’t smell bad, don’t make a mess on the floor, and rarely stop production.

 

The Real Cost of Leaks
One of your factory’s highest operating expenses is the energy consumed by your compressed air system. Only 25% of the cost of a compressed air system is capital cost and maintenance. The remaining 75% is energy, and as much as 35% of that energy is wasted satisfying leaks.

Additional Impacts
Compressed air leaks create fluctuations in system pressure, which negatively impacts product quality. Compressors work overtime to compensate, leading to early degradation of the asset. Eventually, the compressor system can’t keep up with demand. What can you do? Buy yet another compressor for more capacity? Or optimize the capacity you already have by finding and fixing leaks?

With so much at stake, why are compressed air leaks managed so poorly, and why doesn’t every organization have an air leak management program?

 

Where to Look for Leaks
Every component has the potential to leak, but we can hasten our search by focusing on common failure points. Usual problem areas are branch line connections, automatic drain traps, desiccant filters, regulators, coalescent filter assemblies, quick couplers, valves, hoses, fittings, pneumatic cylinders and thread sealants. Most leaks occur at points of use, so begin your search there.

How to Find Leaks
Locating air leaks in a loud factory floor is next to impossible with a human ear. The best, and easiest, way to find air leaks is using ultrasound. Ultrasound detectors allow you to hear the minute hissing noise produced by leaks, despite the roaring noise of a production area. Ultrasound detectors are portable, easy to use and require little training to get started.

SDT have a range of hand-held devices from the entry level LEAKChecker to the SDT340 which can be used for both airborne & structure-borne applications. And now with the all new  SonaVu acoustic imaging camera you can ‘SEE” the leak in real time making it even easier to scan larger areas.

How to Manage Leaks
It’s not enough to just find leaks. Fixing and documenting savings is a necessary part of the program.

Fortunately SDT have simple and easy to use platforms to track and calculate these costs.

LEAKReporter

A mobile smartphone App available for iOS and Android. LEAKReporter is focused, simple and free. It saves inspectors time and money by documenting leaks in pictures, estimating their cost impact and creating fast comprehensive leak reports. This can be used with the LEAKChecker, SDT200, SDT270 or SDT340.

SonaVu InSights™

Is a web application for creating instant reports of compressed air leak and electrical asset surveys performed with the SonaVu Acoustic Imaging Camera from SDT. Document findings, prioritize repairs, estimate cost impact, eliminate energy waste, and save money with this free application.

Being competitive has never been more important than it is today. Energy costs directly impact your bottom line. There is no easier way to reduce energy waste than to tackle the “low hanging fruit” in your compressed air system.

It doesn’t have to be complicated.

Detect, fix and save money with SDT Ultrasound Solutions.

SonaVu Acoustic Imaging Camera identifies vacuum leak within minutes

What is an Acoustic Imaging Camera?

SonaVu™ is an acoustic imaging camera. Using its 112 ultrasound sensors and optical camera, it can detect sources of airborne ultrasound and transmit them into a visual image on its touch screen.

Defects such as compressed air system leaks, compressed gas system leaks, vacuum leaks, the presence of partial discharge on electrical assets, and failed/working steam traps all create turbulence. And when there is turbulent flow present, there is airborne ultrasound. SonaVu™ makes the superhuman hearing capabilities visible to the human eye.

Using an acoustic imaging camera these defects and failure modes can be visualised and pinpointed from up to 50 meters away. And due to the visualisation capabilities of SonaVu™, it’s really easy to use too as demonstrated in the video below.

With minimal device training, maintenance technicians can confidently inspect their assets for defects, long before they cause unexpected downtime.

LUBExpert Case Study: 70% of bearings are still OVER lubricated

Bearings need grease, however… 

It’s a common misconception that if a little grease is good then a lot means better. WRONG!

Too much grease will overheat a bearing causing separation of the oil from its thickener and will begin to run out of the bearing. This can set off a chain reaction resulting in lack of lubrication & hardening of the thickener which left unchecked will cause major issues.

Many studies have shown that only 33% of the open space within a bearing needs to be filled to achieve optimum friction reduction. 

33%? How do you that?

ALS Global (Australia’s largest condition monitoring service provider) conducted an independent study over an 18 month period using the LUBExpert. The device was used across a large volume of grease lubricated bearings which were historically replenished using fixed calculated / time based rates.

Find out why ALS now choose the LUBExpert as their preferred method of lubrication. Download the full case study below.

 

How are you lubricating your bearings?

Ultrasound Inspection On Rotating Assets

front page

GVS Reliability Products in conjunction with SDT Ultrasound Solutions is proud to present the below case study, Ultrasound Inspection On Rotating Assets, submitted by Mike Halls.

Mike is Technical Officer of Condition Monitoring at Rio Tinto’s Yarwun alumina refinery where he has held this position for over seven years. Mike has over 20 years working in the condition monitoring field, utilising popular technologies such as VA, Thermography and Oil Analysis. And now Ultrasound for the last 2 years!

Mike’s years of experience have given him a unique perspective on using ‘alternative’ condition monitoring tools such as the SDT 270 PROthe world’s flagship ultrasound inspection device. With the SDT 270 delivering reliable, repeatable and calibrated ultrasound data and, with the power of signal analysis using SDT’s UAS software, Mike has been able to clearly demonstrate that ultrasound inspection should be the technology of choice for certain applications.

When using Ultrasound inspection technology in a harmonious relationship with other condition monitoring inspection devices, plant coverage increases, as does the overall reliability and availability of monitored assets. This then translates into greater production capacity and therefore overall profitability of an enterprise/company.

A portion of this case history was first published in The Industrial Eye: The official journal of the Australian Institute for Non-Destructive Testing – Condition Monitoring Issue – March/April 2017. 
It has since been edited and rectified to give further information regarding the case.

Read on for Mike’s ultrasound inspection success story…

Case History: Mike Halls – Rio Tinto Yarwun – 16-10-2017

Bearing Life Extension using SDT 270 Contact Ultrasound measurement

vaccum pump

Equipment Details

Equipment: P2620Vacuum Pump

Bearings: Tapered Roller Bearings

Pump Speed: 222 RPM

Motor: 630Kw – 6 Poles

Number of Vacuum Pumps on Site: 21

Costs associated with bearing failure

Overhaul cost due to a bearing failure: $120K
Total Replacement cost: $300K
Costs due to lost production or downtime: Currently there is some redundancy (as long as there are not too many other problems…). This may change in the near as further production demands are made on the plant.

History

Previous vacuum pump equipment failure modes and RCA’s have revealed that there has been an increase in bearing internal clearances & cage wear resulting in premature bearing failure. Due to the nature of these machines, vibration spectral analysis only revealed bearing defects in the later stages of the failure mode. Vibration analysis identified advanced propagation of fatigue due to surface cracks and spalling of the bearing raceway surfaces which were already resulting in unsatisfactory equipment performance.

Contributing factors to consider when using a vibration analysis approach are

a) a relatively low operating speed and

b) fluctuating ‘flow related’ vibration

Both of the above plant characteristics have the tendency to mask the early stage, low level amplitude bearing defect fault frequencies which, had they been detectable, would have indicated sub-surface bearing raceway defects and/or lubrication related anomalies. See the vibration analysis plots below as reference.

Vibration Analysis Plots

Below is the vibration Acceleration & PkVue spectral data taken the day after the acoustic vibration route was collected and, prior to any maintenance or lubricant/greasing intervention. Vibration analysis of the spectral plots indicates that the dominant frequencies relate to the vacuum pump pressure pulse fundamental & related harmonics. Neither of the plots indicates incipient bearing anomalies or lubrication related issues.

vibration analysis_2

Challenge

With traditional condition monitoring technologies being limited in their capacity for detection of the early stages of the bearing failure modes, trending of the degradation process was not possible. Without being able to detect and trend the early stages of the failure modes, this left the plant exposed when needing to determine a projected planned maintenance window. So, once the later stage defects were finally identified, the asset was already at a critical crossroad in

a) needing immediate attention or

b) risk plant failure with consequent potential safety hazards or production loses.

Solution: Acoustic Vibration Monitoring Trial

Acoustic Vibration Monitoring or contact Ultrasound, are terms used when an Ultrasound inspection instrument (in this case the SDT 270 PRO), utilises a sensor to contact (touch) a surface to detect attenuated ultrasound signals. Using a sophisticated instrument such as the SDT 270 PRO, the ultrasound signals can then be acquired as either dynamic (for analysis and playback) or static measurements (for trending) and logged in SDT’s proprietary database, Ultra Analysis Suite (UAS).

Just over twelve months ago, an Acoustic Vibration Monitoring strategy was implemented on a trial basis to complement the vibration analysis program on the vacuum pump routes. This was done mainly to assist with lubrication related concerns and incipient bearing defects that vibration analysis was unable to confidently detect. After employing the ultrasound inspection strategy (with the 270), and the data analysed in UAS, a number of lubrication concerns with the vacuum pump bearings were rapidly identified. See figure 1 and 2 below.

Figure 1. Static trend

Figure 2. Dynamic Signal

dynamic-signal_2

Listen to .WAV sound file at this Dropbox link.

Initial Results and Findings

The above Acoustic Vibration Analysis examples indicate a significant upward trend due to elevated ultrasound generated by the bearings. The ultrasound signal and trend indicate metal to metal contact that is identified by an outer race bearing defect. The causes for this are either inadequate lubrication or incipient bearing defect.

As already mentioned above, at these locations vibration analysis showed only high frequency data with a raised noise floor. This could be attributed to the product ‘flow’ and hence masked the true vibration signal. On the contrary (and unlike vibration), the Ultrasound signal is not affected by the ‘flow’ caused by the pump and hence did not mask/conceal the bearing condition data. Due to the clarity of this anomaly, we can call this a ‘text book case’ because in this example, increased readings in ultrasound data related directly to an inadequate bearing lubrication condition.

Due to the findings via the use of the SDT 270 Ultrasound inspection device, the recommended corrective action was; ‘grease the non-drive end bearing and re-evaluate the ultrasound values’.

Upon the recommendations being carried out in a timely manner, further readings were taken with results shown in Figure 3 and 4 below:

Figure 3. Static trend after recommended intervention

Static-Trend_alt

Figure 4. Dynamic signal after recommended intervention

dynamic-signal_alt

Note: the vertical y axis between fig 2 and 4 is different by approx. a factor of 4

Listen to .WAV sound file at this Dropbox link. 

Secondary Results and Findings

The data collected with the SDT 270 post lubrication intervention shown in figure 3 &4 showed drastically reduced static and dynamic ultrasound signals. Hence, the follow up survey indicated that the values had significantly decreased to within the acceptable ultrasound range. Further inspections were then planned to monitor the health of the asset. Through the unique attributes only available through ultrasound inspection with the SDT 270, the plant was protected.

Conclusion

Cost analysis:

Thanks to Ultrasound inspection and the access to complimentary software, a conservative estimate is that the company avoided a $120K+ cost to overhaul the pump due to a bearing failure. A catastrophic failure ($300K +) and potential compromise to personnel safety and plant production, would have seen the cost to the company far in excess of this $120K estimate.

Technology Analysis:

Ultrasound inspection has unique qualities which were instrumental in allowing condition monitoring to gain a true understanding of the health of the asset. For this application, other condition monitoring technologies were only useful once the asset was in the late stage of this particular failure mode exposing the company to high risks.

Furthermore, with the SDT 270’s ability to collect both dynamic and static data for trending and analysis, and the ability to record and analyse this data in the UAS software, the defect was easily identified and corrective actions taken.

Site Analysis and further actions:

Continued use of Ultrasound inspection technology to identify bearing condition will be employed so as to extend the reliability, availability and life expectancy of these important assets.

When using Ultrasound inspection technology in a harmonious relationship with other condition monitoring inspection devices, plant coverage increases as does the overall reliability and availability of monitored assets.

Thank you for reading.
I hope this study proved to be of use to you confirming best practice in technology integration results in determining a higher accuracy in detecting equipment failure modes.

Take the ‘guess work’ out of Lubrication

Guess what? Lube programs are ‘guess work’

Lubrication is the life blood of a healthy operating rotating machine. This fact was discovered thousands of years agoand employed by the ancient Egyptians in pursuit of greater reliability for their own rotating machinery. E.g. Animal fats applied to wheels of a horse drawn chariot reduced heat and wear on parts!

wood

While lubricants and machinery have evolved from animal fats and cart wheels, what has not changed in all the millennia since then is this: the lack of precise knowledge of quantity and frequency of lubricant application for greatest effectiveness.

Over time through trial and error, we can assume the lube techs and maintenance personnel of ancient Egypt determined the correct time to apply grease/lubricant.

‘That wheel shaft has not been greased for 2 weeks and we travelled through a sand storm yesterday. It’s time to get the animal fat out! But how much should I apply?’

Let’s face it, for a cart wheel, a ‘best guess’ lubrication strategy should probably work fine.

But today in the 21st century, with far more complex rotating machinery, maintenance and lubrication professionals across industry still face the same two critical questions:

‘How much lubricant and when?’

As civilizations have come and gone, greasing programs have still not evolved from the ‘best guess’ approach.

Did I Guess right?

As with our ancient Egyptian forebears, to answer the: ‘How much?’ and ‘When?’ questions, trial and error has led to the conclusions we have made about greasing. From trial and error (testing and research), mathematical formulae have been developed based on; bearing capacity, operational load, rotational speed and operating environment. However, experts agree that this formula is still only the ‘best guess’ regarding grease quantity and frequency of application.

And from this guess work, most industry lubrication programs are based on the calendar.

While calendar based lubrication programs assume that ‘someone’ ‘somewhere’ applied the mathematical formulae to determine the grease quantity and interval, what math can never account for is constant variations in:

  • Load
  • Speed
  • Operating hours
  • Temperature
  • Environment (dust, water, sand etc…)

These variables are critical in the determination of both grease quantity and interval between interventions.

So, we can confidently state: Even the most well thought out lubrication programs running on a calendar basis are ‘best guess’ and not ‘best practice’.

Given that poor lubrication practice (especially over greasing and under greasing), has a significant negative effect on the life cycle of bearings, the question needs to be asked:

Are you happy to leave the healthy operation of your critical assets to guesswork?

Did you answer NO?

Good because now GVS Reliability Products and SDT Ultrasound Solutions can help.

‘Know’ when to grease, not ‘Guess’ when to grease. 

Do you want to ‘know’ when to grease or when not to grease? Do you want to ‘know’ the impact lubricants are having on your precious assets? If yes, then you will need to lubricate with the assistance of Ultrasound technology.

The key to understanding how ultrasound assists with lubrication is this: Friction causes Ultrasound. 

  • Perfect Lubrication (‘sweet spot’) = Lowerfriction = Less Ultrasound = Happy bearing
  • Imperfect Lubrication (under or over greased) = Higher Friction = Higher Ultrasound = Unhappy bearing… ☹

So, given the above information, the premise for the successful lubrication interventions should be this:

Lubricate bearings based on condition/evidence, not on the calendar.

With an SDT ultrasound assisted lubrication strategy, lubrication programs can evolve from ‘best guess’ to ‘best practice’.

With SDT hardware in the hands of a lubrication technician, a source of reliable information (knowledge) as to the friction condition of ANY bearing becomes available. With the knowledge an SDT instrument provides, calendar based programs evolve to become condition based programs.

With the help of Ultrasound, maintenance has the power to change lubrication culture from:

“Hey, it’s 3 months since the last lubrication intervention, therefore my best guess is, it must be time to put 20g of grease into the bearing.”

to

“Hey, it’s 3 months since the last lubrication intervention, therefore it must be time to use my SDT Ultrasound technology to help me determine how much grease to put in the bearing.”

‘I Guess all Ultrasound Lubrication instruments are created equal…?’

‘Best practice’ lubrication is only possible with high quality ultrasound inspection instrumentation.

SDT devices such as the LUBECheckerLUBExpert or 270 provide dB µV data numerically on-screen. This data is reliable and calibrated based on a reference point (1µV = 0dB).

SDT instruments empower operators to confidently say, “when I attached the Ultrasound contact sensor, the screen read ‘X’dB. When I finished greasing the screen now reads ‘Y’dB.”

This is quantifiable data and can be included in reports as evidence given for reasonable action.

The point of the above is this:

  • Numerical data is criticalwhen asking lubrication technicians to grease bearings using technology.

Without credible data, what exactly would we be asking the lubrication techs to do with technology? They can listen but how do they report? ‘Grease the bearing until it gets quieter’. This methodology doesn’t work as ‘louder’ or ‘quieter’ is qualitative and is completely open to interpretation. You might as well just go back to the original guess work!

Prove it

As already mentioned, with an SDT Ultrasound solution, current lubrication strategies can transform into ‘best practice’. By applying the use of the technology, an SDT customer claims the reduction of grease consumption by up to 95%! At the same time, by all measures at their disposal, reliability and plant availability is at an all-time high.

Evolve from ‘Guessing’ to KNOWING!

With the constant development of technology, the way industry lubricates bearings is evolving. Given that evolution simply means ‘change’, then it is time to change.

When it comes to lubrication practices we can now change from:

  • guessing
    to
  • knowing

We can change from:

  • ‘apply 20grams because it’s Tuesday’,
    to
  • ‘it’s Tuesday so I’ll check my Ultrasound data to see if I need to apply 20 grams’.

As with a whole bunch Isralites a few thousand years ago, its time to leave ancient Egyptian practices behind and evolve our practice to survive in a rapidly changing world.

Things evolve. Things change. We are no longer greasing Egyptian chariot wheels. Get on board or risk being the victim of natural selection as the rest of the world changes around you.

Best Practice.

Give your team confidence. Give them the opportunity to perform best practice maintenance. Give them a reliable Ultrasound instrument from SDT!

Learning 101 – Ultrasound

Using Ultrasound for ‘on-condition’ lubrication and bearing health.

This GVS blog post contains a link to a highly informative presentation delivered by none other than SDT’s own, Tom Murphy.

http://reliabilityweb.com/videos/article/on-condition-lubrication-and-bearing-health-using-ultrasound

Premise: The measurement of ultrasound with portable devices to provide an objective assessment of the health of a bearing has been well-documented over the last decade. In more recent times, the interconnection between a grease gun and an ultrasound instrument has taken this process one stage further. Case histories showing how Ultrasound monitoring can be combined with remote lubrication of difficult-access bearings to provide instant feedback on the benefit or otherwise of individual shots of grease.

From GVS point of view, many in Australian and New Zealand are aware of ultrasound being used as a condition monitoring device but, are not up to speed with the power, performance and diverse range of effective applications a modern ultrasound devices (such as the SDT product range) can achieve. Products such as the LUBExpert and SDT270are 2 such modern sophisticated ultrasound monitoring devices.

The presentation aims not only to educate but also, to fill the gap in the knowledge of ultrasound with engineering and maintenance professionals.
