Key Features and Replacement Notes
1. Sealed and Maintenance-Free: Pre-charged with nitrogen at the factory and welded sealed, non-rechargeable. Long service life with no risk of leakage.
2. Non-interchangeable: Different structural design from bladder or piston accumulators; cannot be directly replaced.
3. Common Faults:
- Accumulator failure: Rapid pressure drop, weak operation, jammed movements
- Leakage: Oil seepage from housing or interfaces, requiring complete replacement
4. Installation Notes:
- Keep interfaces clean to prevent contaminants from entering
- Installation direction is arbitrary; recommended with oil port facing downward
- Ensure proper tightening torque to prevent loosening and leakage
