By on February 13, 2020

By now, if you’ve kept up with the VibrAlign balancing “how-to” blogs, you should see that balancing is mostly just a math problem – counteracting forces.  But we haven’t discussed when the balance job is through. When I started balancing fans many years ago, I stopped balancing when: The fan owner said, “that’s much better”, […]

Using Your Laser Alignment System to Check the Validity Rule

| |

By on February 5, 2020

The validity rule is an important concept in precision shaft alignment. It can be used to confirm that your readings are accurate and is why we don’t have to rotate a full 360 degrees in order to get accurate alignment information. Here is a previous blog post with an embedded video that discusses dial indicator […]

Using the Verti-Zontal Process on Wind Turbines with Adjustable Chocks

| |

By on January 15, 2020

  Precision shaft alignment of wind turbine generators mounted on adjustable chocks is as straightforward as when aligning rotating machinery mounted on chocks down at ground level. In the case of a recent NXA Training Class in a Vestas V82 we knew before going up-tower that one revolution of the adjustable chocks equals 1mm. Also, […]

Compressors, Drivers and Alignment Considerations

| |

By on January 9, 2020

The two main types of compressors are dynamic and positive displacement. The positive displacement compressor is probably the one you’re most familiar with.  It traps gas in a volume and then decreases that volume.  The decrease in volume causes a rise in pressure. A dynamic compressor uses a rotating element (usually called an impeller) which […]

By on January 2, 2020

In a previous blog written by Brad Case (Sept 24, 2019), he explained how to perform a repeatability test and why it is good idea to do so. Here are few other items that have contributed to repeatability issues. 1)      The top rails were not sufficiently clean prior to taking readings. Paint was not removed, […]

By on December 16, 2019

At a recent Fixturlaser Smart Machine Checker (SMC) training class, one particular pump came up during the discussions. This pump has been “a problem child” for years. It had been rebuilt recently by one of the class attendees. The mechanic had rebuilt the pump “just as it had come apart” and was certain the impeller […]

How to Reorder Points in the NEST

| |

By on December 9, 2019

Setting up routes is a very easy process in the ONEPROD NEST software and allows you to move machines into any order to allow for expeditious data collection. However, sometimes points need to be rearranged within the machine. Take the gearbox below for example.  Due to its size you don’t want to have to walk […]

By on November 6, 2019

For the field portion of a recent training class, the decision was made to check the alignment on a plastic extruder. At first glance, checking the alignment of the motor shaft to gearbox input shaft is pretty straightforward. However, the output side of the gearbox had two shafts, so maybe this is not so straightforward. […]
