“Good Vibrations” – MRO Magazine article from KSB Pumps

MRO Magazine recently published a good article by Mehran Masoudi from KSB Pumps on vibration in pumps and pumping systems. As we know, vibration can cause serious problems or issues for maintenance departments. This article provides some tips on things like potential sources of vibration, pump vibrations on critical speeds, piping system vibrations and diagnosing them and advice for controlling certain vibrations. Use these tips from one of the most knowledgeable engineering pump solution’s provider in the industry to stem downtime at your plant!

Below is an excerpt from the article:

Vibrations can be a serious problem in pumping systems, leading to rough, noisy operation and even damage to mechanical components. There are a variety of circumstances that can lead to strong vibrations, including balance problems and rotating components, resonance effects  (when the frequency of a periodic driving force matches and natural vibration frequency of a structure) and fluid-structure interactions around a pump or in adjacent piping. The following are just some sources of vibration problems in pumps and piping systems and ways that these can be controlled.

Sources of Vibration

Well-maintained centrifugal pumps operating close to their best efficiency point (BEP) will generally run smoothly. However, rough running can occur if a pump is operated under seriously off-optimal conditions (such as with severely restricted flows). Off-optimal running can also cause extra loads on bearings and pressure pulses in the output stream. There are also potential problems associated with the intake or suction side of pumps. If the available head at the pump’s intake is less than the unit’s NPSHR (net positive suction head required), cavitation can occur, causing vibrations, unbalanced loads on rotating components and damage to the impeller and nearby surfaces. (NPSHR is determined by the pump’s manufacturer, based on test data.) Other intake problems can arise from plugged suction strainers, air entrainment and vortexing (that is, the formation of “whirlpools” near the inlets of submersible pumps when there is low water level in the sump).

Benchmark PDM joins HP Reliability at PEMAC’s MainTrain Conference in Saskatoon

This week we joined up with HP Reliability’s James Kovacevic (pictured above speaking with PEMAC President, Susan Lubell) to exhibit at PEMAC’s MainTrain Conference in Saskatoon. HP Reliability are proud representatives of Benchmark PDM and Easy-Laser alignment and measurement systems in the South Western Ontario region. As such, we were happy to exhibit our brand new alignment systems: the Easy-Laser XT660 Shaft Alignment system and the XT190 BTA Belt Alignment system.

Distributing Easy-Laser products is only part of what HP Reliability does. To put it in a couple sentences, James explains that:

“We provide an online toolbox full of real world tips, techniques, and training your business can implement to achieve world-class efficiency and bring profit back to industry.

We cover every aspect of the reliability & maintenance process depending on your specific needs. From core fundamentals that will allow your organization to build a solid maintenance foundation, to the advanced techniques that have been refined over 12+ years of real-world experience on the shop floors.”

On top of exhibiting at the conference, James also was one of the speakers where he discussed PM Optimization – Integrating “Lean” Into Your Maintenance Strategy.

Easy-Laser release brand new XT660 Shaft Alignment and XT190 BTA Belt Alignment Systems

The Easy-Laser® XT660 is here!

We are happy to announce the next system in Generation XT, the Easy-Laser® XT660, which builds on Easy-Laser’s groundbreaking cross-platform technology. You can use your own iOS/Android phone or tablet as a display unit, or purchase the watertight, rugged XT11. Or why not do both? The app is free to download, both now and in the future. The choice is yours!

The XT660 offers measuring units with dot laser. You now have access to advanced measurement methods, such as continuous sweep and multipoint. You can perform measurements on larger machines and over longer distances. You have even greater potential to perform correct machine installation right from the start, by checking the twist/flatness of the base. In short, Easy-Laser® XT660 is the system for machine aligners who see the bigger picture.

Other new features in the XT Alignment app:

  • It is now possible to set intervals and time periods in order to register measurement values automatically in the Value program.
  • It is now also possible to e-mail measurement reports from the XT11.
  • New program: digital alignment of sheaves/pulleys (accessory required)
  • Improved graphics and interface.

Note that the other new features (above) in the app will also benefit users of the XT440 system. The new version of the app is expected to be available at the AppStore/GooglePlay and on our website at the beginning of October. Click here for more information on the XT660.

Listen to latest Rooted in Reliability podcast on “Condition Monitoring”

The Rooted in Reliability podcast is a weekly Maintenance and Reliability podcast covering common industry challenges and what you can learn from them. Each episode dives deeper into critical issues and explains who you can begin correcting theses maintenance flaws today. Sharing new tips and techniques to help you achieve industry best practice and shining a light on widely debated maintenance topics with special guest experts. In the most recent episode, host James Kovacevic, of HP Reliability, interviews John Lambert, President of Benchmark PDM, in Toronto, Canada. John has 30+ years experience in machinery installation and condition monitoring. He has trained many people over the years on these subjects. Below is an excerpt from James’ post:

Ever wonder why your assets aren’t producing the value they are supposed to even if you have trained staff and big budgets? Are you a fan of Predictive maintenance improvement of your organizational processes? Then, condition monitoring is where you should start. The meaning of this word is as simple as the word itself. You just need to check the state of your asset on a regular basis and as the state of your asset changes, you would know what possible failures that change can lead to and then you can try predictive maintenance strategies to stop that failure from occurring in the first place.

It is sort of like visual inspection of your assets but it involves plenty of measurements that you have to take. These measurements can be standardized as normal and when there’s a difference also called an abnormal measurement reading and you can start monitoring the assets closely by taking the measurements more often. Considering the consequences of these abnormal readings, you may have to make changes in your processes. To know what is the meaning of those readings you need training, experience, and research data. There needs to be some normal standard to which you can compare the readings that you have taken. These standards can be anything starting from the ISO standards for machine vibration or OEM specifications for the equipment and the historical data to make predictions.

Listen to latest Rooted in Reliability podcast on “Understanding Thermal Growth”

The Rooted in Reliability podcast is a weekly Maintenance and Reliability podcast covering common industry challenges and what you can learn from them. Each episode dives deeper into critical issues and explains who you can begin correcting theses maintenance flaws today. Sharing new tips and techniques to help you achieve industry best practice and shining a light on widely debated maintenance topics with special guest experts. In the most recent episode, host James Kovacevic, of HP Reliability, interviews John Lambert, President of Benchmark PDM, in Toronto, Canada. John has 30+ years experience in machinery installation and condition monitoring. He has trained many people over the years on these subjects. Below is an excerpt from James’ post:

In this episode, the thermal growth and the understanding of the phenomenon how it occurs and how to prevent and calculate it is being discussed by John Lambert. So, first of all, we have to know what actually the thermal growth is. The answer is simple. This phenomenon occurs when the rotating machines get hot due to the difference in temperature and they start to expand in every direction. As these machines are mostly metal so their thermal growth is explained by the coefficient of linear thermal expansion that is already known for many different materials.

Now what happens is that organizations don t do the necessary calculations even though these are pretty simple. You can calculate it easily if you have the coefficient of thermal expansion of the material, to what temperature it is to be heated, and the length of material. Their product is what helps you to apply the calculations that you have made for thermal growth and help you prevent the thermal expansion in your machines. You should not think of it as a common issue because it can get critical if you do not address it properly. Measuring it not only makes your shaft alignment better, it also compensates for losses on a regular basis.

“Driven By Precision” – MRO Magazine does Feature Interview with John Lambert in June 2017 Issue

The popular MRO Magazine, who have been “serving machinery & equipment maintenance professionals across Canada” since 2009, have recently published an interview John Lambert in their latest edition. The interview, called “Driven by Precision” features John Lambert, President of Benchmark PDM, and about passing on his many years of experience to the colleges and the next generation.

Below is an excerpt from the interview:

MRO: You recently changed your company name to Benchmark PDM (Precision Driven Maintenance). Why did you make this change?
Lambert: We used to be Benchmark Maintenance Services reflecting the desire to be a service provider. However, because of our strong training programs we became a knowledge-based company and as such we promote a maintenance strategy/philosophy, which is condition-based maintenance. An element of this is precision maintenance. It’s simple; you don’t have to buy anything. All that it is is working to a standard.

MRO: You are on the advisory board at Durham College. Do you teach there?
Lambert: Being on the advisory board is something I enjoy. It’s my way of giving back. I still think of myself as a tradesman and I’m proud of it. The trade has been good to me and I like to help if I can. I don’t teach; they have very good and very qualified instructors at the college. Our role on the board is to advise on industry trends, on new technology being used. On new demands, such as windmill tower maintenance or on growing industries such as elevator service work.
