A
PistoFram
accumulator has a light weight piston where the dynamic seals are aligned
with the piston center, and where both the gas and liquid skirt ends have
graphite filled Teflon guide rings. The hollow piston center contains a
diaphragm which is able to accept or produce liquid flow by instantaneous
deflection during the millisecond or so taken for piston mass acceleration;
producing faster response characteristics than from traditional glued balloon
in can bladder accumulators. At gas or liquid end of stroke the central
diaphragm flow hole cannot align with the inlet out porting that is spaced
either side of centerline, thus there is no encumbrance to flow of anti
extrusion devices.
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.
Main Features: Solid Light-Weight Piston, Close-Coupled
Seals, Dual Graphite-Filled Bearing Strips for Low Stiction, Various Seal
Elastomers, Zero Leakage When Shut Down ,Super Fast R Locking, Flow-Thru
Port Facility.
