Flatness Measurement Repeatability Test

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…

Maintaining Engine and Compressor Crankshaft End Play (Thrust)

Gas engines and reciprocating compressors, used in the gas compression industry, have a certain amount of crankshaft end play or thrust (as it’s commonly called). The amount of thrust is determined by the OEMs of the machines. The crankshafts of these machines must be able to “float” axially to prevent excessive/premature bearing wear. When new…

Compressor Rod Runout with the NXA Runout Probe

The Fixturlaser NXA Runout Probe was introduced last year as an accessory to the Fixturlaser NXA Pro and Ultimate alignment tools.  As originally envisioned, the runout probe was designed with shaft and coupling runout measurements, and direct soft foot measurements in mind. The Runout Probe provides a digital linear displacement measurement, much like a dial…
