Positive/Negative

| | | | |

By on February 7, 2017

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 […]

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 […]

The NXA Extended Alignment Function – What is it? When to use it.

| | | |

By on January 25, 2017

When training clients to use VibrAlign’s Verti-Zontal Alignment Process we show taking the 3rd measurement at a horizontal position, typically at 3 o’clock. This is simply for expediency and is NOT a requirement as Fixturlaser Shaft Alignment Systems can take measurements at any position due to the inclinometers in M & S sensors. If possible […]

The One Tool Missing in Most Aligner’s Toolboxes

| | | | |

By on January 18, 2017

I am going to pass along to you a gift – one that I believe could potentially cut your alignment times-maybe by more than half!  One that could lessen loosening and tightening bolts, reduce frustration, and increase your “alignment” confidence substantially!  Would you like such a gift? Well, here it is – measure your shim […]

Are Flexible Couplings Designed to be Misaligned?

| | | |

By on January 12, 2017

A common misbelief that occasionally comes up in our precision shaft alignment training classes is that, elastomer insert flexible couplings are designed to allow misalignment between rotating machinery shafts.  This is not the case.  Although this type of coupling may be more forgiving to the effects of misalignment, they are definitely not intended to be […]

Maintenance Strategies: Part One

| | |

By on January 4, 2017

In the current highly competitive global economy we live in, there is always a drive to get the competitive edge. One way is to develop a maintenance strategy that will improve safety, meet production goals, increase uptime, increase plant efficiency and thus increase plant profitability. There are four basic maintenance strategies: Breakdown Maintenance Preventive Maintenance […]

Alignment Considerations of Machines with Stiff Elastomeric Couplings

| | | |

By on December 28, 2016

These types of couplings are quite common in industry, and there are various companies producing similar types of couplings.  They are capable of transmitting large amounts of torque in a reasonably small space.  They also do not require lubrication, and are quite easy to install, in most circumstances.  These attributes make them quite desirable in […]

Cutting Corners Can Affect Safety and MTBF

| | |

By on December 21, 2016

As a Millwright, Service Technician or any type of field or in-house Mechanic, we understand there is one main goal that we have in common, which is to keep the equipment running.  This includes repairing and minimizing downtime in the event of an unpredicted failure or breakdown.  Although it’s important to make repairs and perform […]

Back Off Jack Bolts for Improved Alignment Results

| | | | |

By on December 14, 2016

Millwrights and mechanics know the benefits of using jack bolts to precisely control the horizontal position of the movable machine when performing a precision shaft alignment. However, we also see the tendency to tighten the jack bolts, on both sides of the movable machine, either before or after tightening the hold down bolts. Tightening jack […]

Why and How to Measure in Clock Method

| | |

By on December 7, 2016

Proper use of any tool is essential to success in achieving your desired goal. Many tools have optional configurations to adapt that tool to your needs. Fixturlaser Precision Alignment Systems are no different. The alignment tools produced by Acoem/Fixturlaser are second to none in ease of use. The Acoem AB design engineers do all they […]

Base Bound Machinery Corrections

| | | | |

By on December 2, 2016

Most aligners are familiar with a bolt bound situation, which occurs when the motor cannot be moved enough to achieve proper horizontal alignment.  A base bound condition occurs when a motor cannot be lowered sufficiently to achieve proper vertical alignment.  Here is an example.  During a customer’s recent pump replacement, the motor was left in […]

Determining Cold Alignment Targets from OEM Dial Indicator Specifications

| | | | |

By on November 23, 2016

A client was aligning a motor-compressor set and wanted to use the OEM specifications for thermal growth (OL2R) compensation. The manual gave the target values as rim and face dial indicator numbers for either the motor hub or compressor hub. In this case the motor hub specifications were used. He was using the Fixturlaser NXA […]

Other Influences to Precision Shaft Alignment Results

| | | | | |

By on November 9, 2016

Over the years we have fielded several technical support calls from maintenance personnel having repeatability and soft foot issues (during an alignment) all of which had a common issue; other influences. Meaning not the typical looseness, coupling backlash, soft foot issues. During the “heat of the battle” to get the precision shaft alignment job finished […]

Cooling Tower Alignment

| | | |

By on November 4, 2016

Performing Precision Shaft Alignments on Cooling Towers present a unique set of challenges. A recent job is typical of what I find. We were originally called out because on three cooling towers the motors were experiencing high vibration. Some of the challenges include: 1 – Access through shrouds 2 – Ladders often required to gain […]
