Are Shims Causing a Soft Foot Issue?

| | | | |

By on May 15, 2018

One of the many things I love about my job is the numerous challenges we face during the field alignment portion of our Precision Shaft Alignment Training. Prior to the training, there were some repeatability issues when attempting to perform a precision alignment on this piece of equipment. One of the main causes of non-repeatability […]

Challenging, But Not Impossible!

| | | | |

By on April 3, 2018

As we trainers travel around the country conducting precision shaft alignment training, we often run into some fairly harsh work environments during the field portion of the training. At times the equipment that needs to be aligned is caked in product from spills or leaks. This can create a significant challenge when attempting a precision […]

Should Soft Foot Be Corrected in Centrifugal Pumps?

| | |

By on March 20, 2018

  In a previous blog I wrote in Jan of 2016 “Soft Foot Concerns in the Stationary Machine?” soft foot in the pump was causing repeatability issues during a precision shaft alignment. https://vibralign.com/other-topics/soft-foot-concerns-stationary-machine/ Soft foot can also distort the pump casing which can change clearances within the casing. This can shorten the life of the […]

By on February 8, 2018

While on the road conducting precision shaft alignment training I run across a wide range of skill level. It is not uncommon to have a lot of questions. I like it when there are questions, that is usually an indication that the trainees are engaged. It is also not uncommon that a question starts with, […]

What is Misalignment Costing You?

| | | | |

By on November 16, 2017

I recently received a support call from a nearby client, the issue was that the precision shaft alignment of a right-angle gear reducer to a line shaft was taking up to 12 hours (using another brand alignment tool) with little to no success. There are about a dozen of these units in this facility. This […]

BEFORE and AFTER: The Effect on Vibration Levels

| | |

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 […]

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 […]

It’s The Little Things

By on April 20, 2017

When we trainers conduct training, the first thing we want to know is what is your cause of frustration or “pain” when performing a precision shaft alignment. What we consistently hear is repeatability as the foremost cause of frustration. First the laser says add shims, then take them out, then add and so on. In […]

Maintenance Strategies: Part Four – Proactive Maintenance

| | | | |

By on March 16, 2017

Proactive Maintenance includes a number of maintenance strategies, such as Precision Maintenance, Reliability Based Maintenance, Reliability Centered Maintenance, and Root Cause Failure Analysis. The idea is to anticipate and solve problems before they become problems. Reliability Centered maintenance would begin with a study done on a piece of equipment to gain understanding of all its […]

Maintenance Strategies, Part Three – Predictive Maintenance

| | | |

By on February 21, 2017

Predictive Maintenance, also known as Condition Based Maintenance or affectionately known as “if it ain’t broke, don’t fix it” also has its own set of pro’s and con’s. The pro’s: Rotating equipment usually gives warning signs before failure. Vibration level or pattern changes, rise in temperature, wear detected via oil analysis, performance change, motor current […]

Maintenance Strategies: Part Two

| | | |

By on February 1, 2017

Preventive Maintenance, also known as planned maintenance, scheduled maintenance, calendar based maintenance, historical maintenance, etc. has its own set of pro’s and con’s. The theory is machinery has a life cycle. The probability of failure increases as the machine ages so maintenance needs to be performed prior to failure to extend its life and avoid […]

By on October 20, 2016

As a technical trainer for VibrAlign, I do a lot of reading in order to hopefully continuously improve. I am also very curious.  Quite often I run across articles I believe are worth sharing. This article was on LinkedIn, an IDCON reliability and maintenance discussion written by Mr. Ken Latino. In case you have not […]

By on September 30, 2016

It really doesn’t matter the industry; industrial maintenance technicians suffer the same frustrations when performing a precision shaft alignment. Our team of trainer’s travel all over the country conducting training classes for paper mills, steel mills, chemical plants, gas and oil, etc. What we hear is universal across all industry. “I can’t get repeatable results, […]

Three Major Contributors to Equipment Failure

| | | |

By on August 24, 2016

Past maintenance & production issues found in the industrial or manufacturing environment are still prevalent even in today’s equipment reliability focus. The major contributors to equipment failure remain the same, misalignment, unbalance and assembly errors. Another is lubrication, Mr. Stan Riddle addressed this in one his blogs “Machinery Vibration Problems part 3 – Lubrication”. Let’s […]
