Case Studies
11K Rod Seal Solves Fluid Leakage in Large Press with Minimal Disassembly
Challenge
Background
A 5,000-ton press had issues with leakage of hydraulic oil around the ram. The equipment was quite old and in need of repair. Due to the size of the equipment, it was not possible to completely disassemble it. The medium being compacted was Zirconium powder, which may be used in applications such as high density hydrogen storage.
5,000-ton compaction press was too large to disassemble.
Solution
Product
A Chesterton® 11K Rod Seal set with a spacer and a 9K AER Backup Ring designed tight to the outer diameter of the packing chamber were selected to make installation less challenging. Installation occurred overhead and the interference fit was intended to help in this process.
Leakage around rams was evident.
Results
No Fluid Loss and Smooth Actuation
The Chesterton solution resulted in minimal equipment downtime with equipment soon returning to production. Further, the equipment was quite old, so the softer blue AWC825 primary seal conformed well to the worn seal surfaces. Overall, the result of the solution was smoother system actuation with no oil leakage following installation.
