HydroTrole piston accumulators have a sealing geometry
that ensures pre-charge gas retention with immeasurable loss over an MTBF
(meantime between failure) design criteria of 32 million cycles, with minimum
hysteresis break out stiction achieved by placing the dynamic seals so closely
adjacent each other that seal deflection ensures that the lubricant held
between the seals instantly reaches the same pressure as the oil and the
pre-charge gas. All pistons with so lightly loaded dynamic seals are prevented
from experiencing a differential pressure at gas end and at liquid end of
stroke by a static encapsulated shut-down seal than face seals against the
end of the piston skirt on each side. Piston accumulators are recommended
because when they do begin to go down it is gradual progressive, and determinate.
They are recommended for emergency standby power.
