Thermal Growth with Daus Studenberg

When a machine heats up and starts expanding in all the directions is simply called the thermal growth. When it actually comes to understanding it, it means that you are dealing with machinery movement and that can cause misalignment in the machine. Also, your alignment is only as good as your target. If your machine starts moving and you have a bearable misalignment in the off-set condition, you will allow that bear minimum of misalignment in your machine deliberately in that condition. So, before you detect thermal growth, you need to have a correct target in place to measure it against.

In this episode, we focus on the following points:

  • What is thermal growth?
  • What are the standards of thermal growth measurement?
  • What packages are available that come with laser alignment tools?

And much more!

Understanding Thermal Growth with John Lambert

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.

297 – The Silent Killer of Rotating Machinery – Softfoot with Daus Studenberg

297 – The Silent Killer of Rotating Machinery – Softfoot with Daus Studenberg

The Silent Killer of Rotating Machinery – Softfoot with Daus Studenberg

It is my pleasure to welcome Daus Studenberg to the podcast, the product manager, a national product manager of the alignment with Lu DACA.

In this episode we covered:

  • How many ways can we?
  • What is soft foot?
  • If we’re going to perform a proper installation, we got to consider soft foot. Is that before or after we do an alignment?

The 7 Steps to Proper Machinery Alignment

How to Ensure Your Assets are Installed to Prevent Premature Failure

How many times has an asset been installed or commissioned, only to have it fail in a few days or months when it should have lasted even longer?  If you look at the study by Nowlan & Heap, they have found that only 11% of failures are age related, so when is happening with these assets?  The answer… comes down to poor installation practices.

Ensuring Equipment Doesn’t Grow Out of Alignment

Understanding & Compensating for Thermal Growth

A major asset is being installed, and the asset is vital to the success of a brand new, high-profit product being introduced to the site.  This product is enough to keep the site operational for many years to come.  The installation of the asset is critical, and there is extensive prep work to eliminate soft foot, ensuring the base is flat (using geometric measurement) and that the asset is aligned properly.

109 – Top 10 Machinery Installation Issues with John Lambert

109 – Top 10 Machinery Installation Issues with John Lambert

Top 10 Machinery Installation Issues with John Lambert

When you are installing a new machinery in a facility of the organization, there are certain issues. These issues are listed from top to the bottom categorized on the basis of seriousness. The top of the list is shaft alignment. It is the most common issue while installing the machinery. It occurs due to lack training or of precision instruments, as well as measurement misconceptions. Most organizations think they have achieved alignment just because an instrument showed so. They don’t take the stress and heating mechanisms into account which causes misalignment between the collinear wings of the shaft.

Steam Trap Operation and Selection

Steam Trap Operation and Selection

This article covers the operation of steam traps and how they work. Steam is a greatly used medium. Its use ranges from heating process and domestic fluids through to driving turbines by the expansion of the vapour. Yet the steam trap at the bottom of a drop leg is easily forgotten.  [Read more…]

O-Ring Design, Operation and Use

O-Ring Design, Operation and Use

Properly designed o-ring grooves and properly installed o-rings stop the passage of pressurised liquids or gasses. Flexibility while being deformed under pressure is their greatest sealing advantage.  O-Ring Design and Materials O-rings are made of elastomeric materials such as rubbers and plastics. They deform under pressure and then return back to their original shape once the pressure is removed. They also accept the movement of mirror-finish shafts while deformed by pressure. Usually they are shaped like a rubber elastic band of round cross section, but they can have rectangular, trapezoid and even ‘+’ shapes depending on the application. The material, internal diameter (ID) and cross section diameter specify o-rings of round cross section.  [Read more…]

Angular Contact Bearings

Angular Contact Bearings

They are used on shafts that encounter axial forces or combined loads (both axial and radial forces). Examples are centrifugal and helical rotor pump shafts and helical and worm gear shafts in gearboxes. Their design only permits axial forces in one direction. For alternating axial loads they must be installed as a bearing set to accommodated the forces from both directions. When set back to back, and less so when set face to face, they act to stiffen the shaft and handle larger bending moments such as overhung components or high midpoint shaft loading.

The Importance of Fit, Tolerance & Clearance

The Importance of Fit, Tolerance & Clearance

Many equipment breakdowns and stoppages occur because of improper clearance between holes and shafts.

The shaft is too tight in the hole; the center of the hole is not at the center of the shaft making it off-center; one part is loose on another and slips out of place or does not seal as it should.  [Read more…]

19 – The Role of Alignment in Precision Maintenance with Alan Luedeking

19 – The Role of Alignment in Precision Maintenance with Alan Luedeking

The Role of Alignment in Precision Maintenance with Alan Luedeking

In today’s episode, our guest is Alan Luedeking and the topic of discussion is alignment and precision maintenance. The first thing that pops up into the mind is that where to start with the precision maintenance. The first step can be keeping all of your equipment aligned because that really helps to avoid common problems in equipment. The alignment saves you a lot of money, increases the productivity, and efficiency. After this, we can start monitoring activities all along the way.

Fatigue

Fatigue

Fatigue is a common degradation and failure mechanism. It involves localized, permanent damage to metals exposed to cyclic stress. The stress can be uniaxial, bending, or torsional resulting from a variety of sources including an applied force, vibration, acceleration and deceleration, and differences in thermal expansion between mating components exposed to heating and cooling cycles. Localized means the damage is confined to a small portion of a component or joint.

RCA and How to Understand the Basics of Component Failure 

When performing a PROACT® Root Cause Analysis (RCA) there is a data collection step called ‘Preserve’ (or the PR in the PROACT acronym) which requires the team to collect failed parts, conduct interviews, obtain paper data and positional information after an undesirable event occurs.
