In the next day I will analyze a system that is composed of an induction motor of 60 hp and 1750 rpm. The motor has two DE (drive end) where two oil-hydraulic vane pumps are coupled on both sides.
It's the first time I get this kind of arrangement.
What should I expect in the spectra?
Does anyone have experience in this type of arrangement?
Is it advisable to make measurements at 100% load or 0% load?
As always, thanks for your good comments!
