piston ring low leakage in slow hyraulic service
piston ring low leakage in slow hyraulic service
(OP)
I would like to know the ring design used to reduce leakage in large slow moving hyraulic service. How do we calculate the leakage?
How many rings should be used for a pressure of 300 psi?
Is there a chart to know how many rings to use for a given pressure differential?

One is sufficient. Multiples are not better.
There is normally leakage amounting to a thin film on the rod. I'm not sure how to calculate it, or why anyone would need to.
Really slow motion can be a challenge; Balseals(r) can be a solution, but they fit in o-ring grooves, so start with o-rings.
