Bladder Type

A bladder type accumulator, sometimes known as a hydro-pneumatic accumulator, is a metal tank that contains a rubber bladder filled with compressed gas. There is also a poppet valve in the discharge port and a gas valve used to precharge the bladder.

Advantages of the Bladder Type Accumulator

The bladder is made of a light and flexible synthetic rubber which means there is virtually no resistance to movement.
Because of this, a bladder type accumulator can respond nearly instantaneously to changes in the hydraulic system.

Bladder Type Failure

The rubber bladder – which allows the bladder type accumulator to respond so quickly to pressure changes — is also the greatest point of failure.
Because the bladder is made of rubber, it is vulnerable to cold environments. Extended periods of time in the cold can cause the bladder to become brittle, and a brittle bladder is prone to bursting.

Piston Type

A piston type accumulator does away with the gas filled bladder. Instead there is a sealed piston that separates the gas-filled side of the accumulator from the oil-filled side.

Advantages of the Piston Type Accumulator

Piston type accumulators have several advantages over other designs. Because of their simple design, piston accumulators are more durable and require less maintenance.

Piston Accumulator

One way is to use a pressure gauge or a transducer to detect the pressure on the gas side of the accumulator. This allows us to detect any increase of the precharge pressure.

Another technique is to have a piston position sensor added to the accumulator.
Tracking the position of the piston can determine if it is in the expected position for a given system pressure. Deviations change.

Pressure changes occur in a hydraulic system when the oil is subject to rising or falling temperatures. There may also be a pressure drop due to leakage of hydraulic oils. Accumulators compensate for such pressure changes by delivering or receiving a small amount of hydraulic oils. In the event the main power source should fail or be stop, the accumulator would act as an auxiliary power source, to maintain the pressure in the system.

Accumulators can be use in a pre-charge application for rapid oil flow when command by other components in a system.

Accumulators can be used as time delay devices for shutting down SDV’s in some particular order.
Particular attention must be paid when determining how much nitrogen pre-charge pressure is used per application.
Never pre-charge the gas side of the accumulator with oxygen or shop air.

OPERATION

 Piston type accumulator that provides a mean for regulating the performance of a hydraulic system. It is suitable for storing hydraulic energy under high pressure, absorbing hydraulic shocks and dampening pump pulsation and flow fluctuations. The anodized aircraft grade aluminum construction allows for high corrosion resistance in harsh environments. The honed bore and wear ring allow for a smooth stroke, maximizing the total life cycle. The simple design also allows the RAIL to be disassembled and cleaned without the need for any special tools.
