The First Rule in Precision Shaft Alignment is “Don’t Assume”!

| | | |

By on October 6, 2017

This is an obvious statement and most of us know what happens when we do “ASSUME” with most things in life. However, we (The VibrAlign Trainers) see assumptions being made quite often during a precision shaft alignment. Several years ago, I read a book titled “A Millwright’s Guide to Motor/Pump Alignment” by Tommy “T-Hammer” Harlon […]

By on September 7, 2017

Whether instructing a training class for precision shaft alignment or geometric measurements, the topic of machine specifications frequently comes up. Specifications such as shaft alignment tolerances, bolt torque values, frame or base flatness requirements and the frequency of verification of these specifications are typical of what is asked. There are general industry specifications such as […]

Fire Pump Maintenance

By on August 30, 2017

Fire Pumps are a critical safety item in facilities across the world. Their purpose is to make sure a building has enough water pressure in case of a fire emergency. Of course, the hope is that they are never needed but if they are they need to perform reliably. Fire Pumps are typically tested on […]

By on August 24, 2017

One of the most enjoyable parts of precision shaft alignment training for me as a trainer, is the field portion. This provides the opportunity to build confidence that what the students learn in the classroom, really works in the field! In a recent Fixturlaser GO Basic class, the decision was made to align two recently […]

Precision Alignment and Balance isn’t Important – Unless you care about budgets and the reliability of your rotating assets.

By on August 16, 2017

I read an interesting article in the June/July 17 issue of Uptime Magazine. It was titled “The Reliability Impact Within the P-F Curve” by Randy Riddell. Randy is the Reliability Manager for the SCA Barton Mill in Alabama. I encourage you to read the full article (https://reliabilityweb.com/articles/entry/the-reliability-impact-within-the-p-f-curve). The article includes the following graphic that I […]

Rolled Steel Frame Electric Motors

| | |

By on August 9, 2017

In the precision shaft alignment business, we encounter all types of electric motors.  One type we come across are “Rolled Steel Frame” (RSF) motors.  These motors have a frame housing and feet that are made from mild, rolled steel.  They range from very small up to about 25hp.  They are common in many industries; however, […]

Fresh Perspective

By on July 26, 2017

We all have run into situations where things just aren’t working out the way we think they should. Kind of like not seeing the forest for the tree’s. Part of our profession as trainers at VibrAlign is fielding support calls when a client has questions or has reached the point of frustration where they just […]

Critical Machines? It Depends on Who You Ask

| | | |

By on July 20, 2017

I recently taught alignment training at a gas compression site.  These were sharp technicians, and they keep these large gas compressors in excellent shape.  We went out to check alignment between the engine and compressor.  It was great just as I expected, because compressing gas is their only product. So I asked if they had […]

The Cure for Alignment Frustration!

| | | |

By on June 28, 2017

A customer called me, extremely frustrated, because he could not get a good alignment.  “I’ve spent two hours trying to align this stupid pump!” he said.  He blamed the laser, the “cheap” pump his company had, the bad base, his bad trainer (me), and anything else that came to mind. I did not take it […]

Correcting for base bound or bolt bound conditions.

| | | | |

By on June 12, 2017

A question often asked during our training classes is how to deal with base bound and/or bolt bound conditions when performing a precision shaft alignment on rotating machinery. Base bound is the vertical condition that occurs when the moveable machine needs to be lowered but is “bound” by the base due to an insufficient number […]

Roughing In Before Precision Shaft Alignment

| | | | |

By on June 1, 2017

Some people believe that precision laser shaft alignment has evolved to the point where pre-alignment steps, such as roughing in the alignment with a straightedge, are no longer needed.  Well, quite frankly, those people are wrong! The reason for roughing in the alignment has little to do with how accurately the lasers/sensors measure.  It has […]

Precision Shaft Alignment with Adjustable Chocks

| | |

By on May 17, 2017

We have written, here on the VibrAlign blog, about adjustable chocks used in place of shims for vertical adjustment and machine support. A recent experience at a customer site prompted this article, to share a simple tip that could save valuable time and effort. The customer was using vertical jack bolts while viewing live alignment […]

Save Time. Save Money.

Time is a commodity maintenance personnel typically have in short supply. We hear quite often, in our on-site Shaft Alignment Best Practices training classes, “………. doesn’t give us enough time for a proper shaft alignment”. So how can maintenance personnel get more time for shaft alignment? Stop wasting it! I had the pleasure of working […]

Precision Shaft Alignment of Machines With Small Diameter Shafts

| | | |

By on April 27, 2017

A VibrAlign customer recently called, stating they were having repeatability problems with aligning a small motor to gearbox to pump.  After some phone conversation, I asked if they could send me photos of the machine, and the discrepancy in the measurements.  After seeing them, I knew what the problem was.   Machines with small diameter […]
