Peter,
I haven’t had to setup an accumulator in a little while for a hydraulic motion system and i cant seem to find my hydraulics systems fundamentals book that i received when i was on my last training course. Is there a general rule of thumb or a formula for correctly setting the pre-charge pressure in an Accumulator? I am working on a customers system right now which has a 1500 PSI operating pressure and the accumulator precharge is 2100 PSI…which seems way to high.
Thanks
