The following safety instructions must always be followed when working with hydraulic accumulators: This guide discusses how to disassemble and install a new bladder in Parker Hannifin’s BA Series Only use an inert gas like nitrogen for a Accumulators. This guide is to be read thoroughly, pre-charging.
Since hydraulic accumulators are pressure vessels, the installation, commissioning, disassembly, and maintenance should be performed by professionally trained and qualified personnel.
Never attempt to disassemble the accumulator while it is under pressure. Always assume the accumulator is under pressure until it is confirmed that it isn’t. Never add unnecessary weight or load on top of the accumulator, never use the accumulator as a structural support and never step on them.
Since hydraulic accumulators are pressure vessels, the installation, commissioning, disassembly, and maintenance should be performed by professionally trained and qualified personnel. Only use an inert gas like nitrogen for a pre-charging. Nitrogen that is 99.99 percent by volume is strongly recommended.
Used to remove hydraulic port assembly from the accumulator. Rounded edges. Used to tuck in hydraulic port O-ring. Cleaning: All metal parts should be cleaned with a cleaning agent. Seals and soft parts should be wiped clean. Bladder (Item 2): Inflate bladder to normal size. Wash bladder with a soap solution.
Install accumulator on machine. Figure 1: Once the accumulator has been removed from the equipment, the accumulator body should be secured in a vise, preferably a chain vise. If a standard jaw vise is used, brass inserts should be used to protect the accumulator hydraulic port assembly (Item 7) from damage.
