1. Understanding Accumulator Structure & Lock Nut Disassembly

• Familiarize yourself with the accumulator structure and functions.
• Identify all component names and understand troubleshooting steps.
• Disassemble the lock nut used to secure the valve.
• Remove the spacer for further disassembly.

2. Disassembling Valve & Anti-Extrusion Ring

• Push the valve inward to separate it from the anti-extrusion ring.
• Remove the valve from the bottle after separation.
• Take out the O-ring and support ring from inside the bottle
• Extract the anti-extrusion ring from the bottle.

3. Disassembling Lock Nut & Gas Valve Insert

• Loosen and remove the eye-bolt and seal cap.
• Disassemble the lock nut securing the gas valve.
• Release pressure inside the bladder.
• Remove the gas valve insert.

4. Removing Bladder & Cleaning the Bottle

• Extract the bladder from the bottle.
• Clean the interior of the bottle thoroughly to remove any contaminants.

5. Bladder Leak Check & Insertion

• Inflate the new bladder and check for leaks.
• Insert the new bladder into the bottle carefully.

6. Reassembling Anti-Extrusion Ring & Valve

• Insert the O-ring and support ring into the bottle.
• Place the anti-extrusion ring back into the bottle.
• Insert the valve into the bottle and connect it securely with the anti-extrusion ring.

7. Assembling O-Ring & Valve Lock Nut

• Assemble the O-ring and support ring onto the valve.
• Attach the spacer to the valve.
• Tightly secure the lock nut to fix the valve in place.

8. Assembling Gas Valve Insert & Lock Nut

• Tighten the lock nut to secure the gas valve firmly.
• Reattach the eye-bolt and seal cap securely onto the gas valve.
• Reassemble the gas valve insert that was previously removed.

9. N₂ Charging & Leak Check

• Use a booster to inject N₂ (Nitrogen) into the accumulator.
• Alternatively, connect directly to an N₂ bottle without a booster.
• After charging, check for any N₂ leaks to ensure proper sealing.

10. Assembling I-Bolt & Bladder Damage Inspection

• Secure the I-bolt onto the gas valve for transport.
• Inspect the replaced bladder to identify any damage and determine the cause of failure.
