Part 24 - Rotor Balancing (of rotating masses) 

Your support means everything to us. If you find value in our videos, please consider sharing them with someone who would benefit. Thank you so much!

Many thanks!, nicely put; still have to see the rest of your videos but it would be great if you could comment on the high speed balancing procedure and some of these topics: - balancing machine bearings (sleeve bearings, not always the actual tilting pad job bearings) - pedestal stiffness vs actual turbine pedestal stiffness, (is the test HSB vibration amplitude representative of what will be later seen during machine operation? - though not an API criteria, many users actually want to see the eddy current vibrations amplitude during HSB, as that is what trips the machine later on, and ask for very low amplitude after the test… HSB is sometimes seen as a preliminary “factory acceptance test” Again thanks for the effort in putting all these videos together, they are incredibly educational!
