Shaft Alignment

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 […]

How Long Will a CNC Machine Stay in Alignment?

| | | | | |

By on July 24, 2019

This is not an easy question to answer. We all know that machines can move and don’t stay level forever. Do you ever have a crash on your machine that could throw off the alignment? While we hope this doesn’t happen often, the reality is, crashes and wrecks do happen.  However, there are some things […]
