Products / Parker / Cylinders and Actuators / Industrial Piston Accumulator For High Performance Applications - AP Series
Piston Accumulators up to 300 Litres volume, 360mm Bore, 250 Bar & 350 Bar.Parker AP piston accumulators offer quality design and premium technical features which guarantee optimum performance life.
Parker’s AP piston accumulators are a premium specification product
designed for use in high performance applications such as industrial
press, die casting and plastic injection moulding, where large
volumes of fluid have to be displaced at high speed (250 & 350 bar).
A wide range of bore/stroke combinations enables the piston
accumulator with the required volume to be selected in a size that
will optimise the use of available space, while metric mountings and
a choice of port styles simplify connection. Parker offers a full
range of clamps to provide secure mounting.
Parker Olaer have developed very sophisticated simulation software
to optimize sizing recommendations for hydraulic accumulators. You
can download the accumulator sizing software from the Product
Support tab.
Markets:
• Industrial
• Oil & Gas
• Energy
Features/Benefits:
• Special multi-element sealing systems have been developed to
combine good servo application and load holding properties with the
wear characteristics required to withstand continuous use at piston
speeds of up to 8m/s.
• For unique applications and hostile environments, different
designs, materials and coatings can be supplied. Please contact your
local Parker sales company to discuss custom solutions to individual
application requirements.
• 180mm and 250mm bore accumulators feature threaded caps to
minimize downtime and simplify maintenance of the accumulator,
permitting quick and easy installation of seals. 360mm bore units
use a screwed ring to retain the gas and oil caps, reducing the mass
of parts handled during maintenance and providing additional
protection for the gas valve.
• Carbon steel body and Aluminium piston design.
• High burst test safety factor.
Applications:
• Die casting
• Plastic injection moulding
• Presses
• Machine tools
• Renewable energy
Function:
Hydraulic accumulators are an essential component for the optimum
operation of a hydraulic circuit. The accumulator enables:
• Energy Storage: Saves energy without loss and redistributes when
required therefore reducing installed power.
• Pressure Compensation: Absorbs pressure spikes from pumps or other
components to control pressure and flow rates in the hydraulic
circuit.
• Volume Control: Absorbs fluid volume variations induced by
temperature changes in a closed hydraulic circuit and maintains a
rated pressure.
• Emergency Energy Storage: In case of failure of the main energy
source, these accumulators can provide sufficient energy to complete
an operation or to realize a full hydraulic cycle.
• Hydraulic Spring/Shock Absorber: A piston accumulator can act as a
gas spring suppressing shocks and vibrations in hydraulic systems of
lifting vehicles (e.g. Forklift trucks) and maintains real
suspension of the load on a gas spring.
