Alignment Check vs. Alignment

| | | |

By on March 7, 2019

One question that arises regularly in training is about doing alignment checks. Is it okay to just check the alignment? Of course, it is.

A Vector Approach to Single Plane Balancing

| |

By on February 7, 2019

Unbalance (Imbalance) is often defined as the unequal distribution of the weight of a rotor about its rotating centerline. A rotor can be balanced either in-place or in a balancing machine assuming unbalance is the issue and weight can be added or removed.  Modern balancing instruments will do the math for you. I originally learned […]

How to Read an Alignment Report Part 2 – Thermal Growth Targets

| | |

By on January 23, 2019

The goal of a precision alignment is to align the machine within tolerance when at operating condition. Many, but not all, machines are aligned without the need to compensate for offline to running (OL2R) movement most often associated with thermal growth. A previous blog post (see link below) discussed how to read an alignment report […]

How Do You Align Machinery on a Flexible Base?

| | |

By on November 20, 2018

This is as much a title for a blog as it is a question. One our Technical Trainers once stated that to align rotating machinery, they must first be alignable. What is meant in part by this is that when we have a collinear tolerance of 0.5mil /1” angularity and 2.0 mils offset, the machines […]
