When we align equipment, we are aligning the rotational centerlines of the shafts. We have a stationary machine and a moveable machine. In most cases the stationary machine’s center of rotation is the target and reference for all measurements and corrections of the movable machine. When reading laser or dial indicator values, the terms of […]

By on January 5, 2016

In his blog post “Repeatability vs. Desired Outcome – parts 1&2”, Stan Riddle, one of my fellow technical trainers for VibrAlign, explains why alignment results may vary from the expected outcome. He explains in some detail a number of causes and how they are affecting your alignment process. Many of these causes could be eliminated […]

Repeatability vs. Desired Outcome in Shaft Alignment, Part 2

| | | |

By on December 2, 2015

In my last post, we looked some reasons for non repeatable, or when “two plus two doesn’t equal four”. This time, let’s think about when we don’t get an expected or desired outcome when we shim and move. Think of it as when “two minus two doesn’t equal zero.” You may perform an alignment measurement, […]

Repeatability vs. Desired Outcome in Precision Shaft Alignment, Part 1

| | | |

By on October 14, 2015

When mechanics align rotating machinery, they expect two outcomes. One, they expect their alignment values to be repeatable. Two, they expect shimming and moving machinery to produce a desired outcome-namely, to be in tolerance. In this paper, we’ll discuss repeatability, which is, performing the same measurement twice, and getting the same results. If alignment results […]

By on September 3, 2015

In my nearly 38 years of industrial maintenance, I have had the opportunity to work on high speed precision machinery. Most often this is highly automated equipment with photo eyes that determine which function needs to occur for the next sequence. After a few instances of frustration, I found that most often when a particular […]

By on June 25, 2015

There are many pump types, sizes and applications. Positive displacement: gear, screw, progressive cavity, lobe, peristaltic, diaphragm, Velocity: radial & axial flow, mixed flow, educator, etc. With all the various pump types, sizes and applications it would be quite the feat to list the exact cost for each one in this blog. I will leave […]

By on September 17, 2014

After completing a recent training class, I had opportunity to ask our customer what were some of the highest cost failures they experienced. The answer? Mechanical seal failures. Mechanical seals come in a wide variety of configurations and manufacturers. The cost of these seals can range from $1000 to $3000 per inch of shaft diameter. […]

Precision Shaft Alignment and Energy Consumption

| |

By on February 25, 2014

It has been a long standing belief amongst maintenance and reliability professionals that electric motor energy consumption must be less when rotating machines are precision aligned vs. when misaligned.  There have been several studies on this subject that have shown varied results, from 1% to as much as 10% less energy consumption for a precision […]

By on February 6, 2014

Any aligner knows that not properly correcting soft foot during a precision shaft alignment leads to frustration and anguish, not to mention wasted time. Soft foot is such a problem there has been numerous articles on The Alignment Blog the past few years about the subject. The articles discuss the many causes of soft foot […]

By on September 9, 2013

During a recent Fixturlaser GO Pro Training class, at a mid-west university, we performed a shaft alignment on a large Flowserve HVAC pump with a 500 HP electric motor.  This motor was large enough that multiple people could work on both sides without really seeing each other.  Well, that proved to be an issue with […]

The Shaft Alignment Nightmare

| | | | | |

By on April 10, 2013

Sometimes precision laser shaft alignment is a quick, neat, orderly maintenance task.  And sometimes, it is not!  Occasionally, everything that can be wrong IS wrong. While teaching a Fixturlaser Go Pro training class in Illinois, the class went into the plant for some “hands on” shaft alignment work.  The machine chosen was a 25 HP […]
