By on February 20, 2020

Years ago, an automotive oil filter company’s ad campaign, capitalized on the phrase “pay me now, or pay me later”. The premise was that you could pay less upfront for an inferior oil filter, and then pay again because the oil filter would fail, and your vehicle’s engine would require an overhaul. Or, you could […]

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 […]

Flatness Measurement Repeatability Test

| | | |

By on September 24, 2019

When performing the Ariel ER-82 Top Plane Compressor Frame Measurement, surrounding reciprocating compressors in operation may cause repeatability issues due to excessive vibration. To compensate for high/excessive vibration the Sampling Time (measurement time at each measurement location) in the Fixturlaser NXA Ultimate can be lengthened as needed. The NXA has a built in Repeatability Test […]
