Using the AlignHot App (Hot Check) to Determine Thermal Growth Targets

| | | |

By on July 23, 2015

A previous blog of mine discussed the benefit of taking a set of hot alignment readings to verify if the offset targets used for a cold alignment, to compensate for thermal growth (dynamic movement), were correct.  http://thealignmentblog.com/blog/2015/04/15/benefit-hot-alignment-check/ So what if the actual hot alignment readings you get show a large difference from the anticipated hot […]

Understanding Alignment Target Data from the VibrAlign ThermAlign App

| | |

By on May 13, 2015

Dynamic Movement, often thought of as thermal growth, is a hot topic among alignment professionals (I’ll be here all week!). Plant Services Magazine in conjunction with VibrAlign recently hosted a webinar on this subject (details below). One of the more popular ways to compensate for thermal growth is through the use of a thermal growth […]

The Benefit of a “Hot” Alignment Check

| | | |

By on April 15, 2015

There have been numerous posts on TheAlignmentBlog.com dealing with Thermal Growth and Dynamic Movement of rotating machinery. http://thealignmentblog.com/blog/category/alignment-troubleshooting/dynamic-movement/. Thermal Growth continues to be a subject that is discussed and taught in our training classes, though on a daily basis is not always correctly compensated for in industry. Many maintenance personnel performing precision shaft alignments use […]

OL2R – The True Measure of a Machine’s Movement

| | | | | |

By on December 11, 2014

OL2R is the acronym for OffLine 2 Running. OL2R is an optional program and special precision bracket set that is available for the Fixturlaser NXA Pro & Ultimate (also XA Pro & Ultimate). This option allows the shaft aligner to accurately measure vertical AND horizontal changes of machines from a static (OffLine) position to a […]

“Where can I get alignment specifications?”

| | | | |

By on December 3, 2013

This is a question that comes up surprisingly often in our training classes. The question is usually regarding Thermal Growth offsets (dynamic movement) and shaft alignment tolerances. There are several ways to obtain the data in question. The easiest and most readily available would be the equipment manufacturer. Most companies will supply specific offset and […]

Calculating Foot Target Values

| | |

By on January 23, 2012

A couple of weeks ago we calculated cold alignment targets from field data. We ended up with angles and offsets but the class wanted to go through the math involved in calculating the foot values. It was an interesting math exercise so if you’re up for some brain stretching, follow along. Here are our target […]

How Does Calculating Your Own Alignment Targets Work?

| | | | |

By on January 13, 2012

A recent training class offered us an opportunity to check both the hot and cold alignment conditions on a blower. It was a great time to calculate our own thermal offset values from field data and compare them to the OEM recommendation. So how do we go about doing this? Why would we even want […]
