We all agree that machinery will perform better when it is properly aligned. The snag is that word "properly". We believe that all machines have an optimum alignment profile, which takes into account the changes in the shaft train when the unit is operating. Differential thermal growth, rotational displacement, and foundation fastening restraints all affect the final position of the shaft/shafts, and need to be considered.
Due to our wide experience with all types of rotating machinery, we can often predict the offsets required with accuracy. Where doubt exists, we can measure the movements of the machine casing during shutdown, using precision optics and laser-based systems, and factor the measured offsets into the final re-alignment.
