ACCUMULATOR

The ACCUMULATOR 3115 3451 81 (3115345181, 3115-3451-81, ACCUMULATOR 3115345181) is a high-pressure hydraulic accumulator block engineered for ATLAS COPCO and EPIROC drilling rigs. Designed for mining and tunneling duty, the ACCUMULATOR 3115 3451 81 stores and releases hydraulic energy to stabilize system pressure under rapidly changing drilling loads.

This ACCUMULATOR 3115 3451 81 absorbs and moderates hydraulic shock loads generated by feed cylinders, rotation drives, and impact systems. By damping pressure spikes, 3115345181 protects pumps, seals, hoses, and valve assemblies from cavitation, vibration, over-pressurization, and machine-oil aeration. The identifiers 3115345181 and 3115-3451-81 are commonly used catalog variations for the same assembly.

The ACCUMULATOR 3115 3451 81 maintains consistent hydraulic delivery to rotation, percussion, and feed systems, improving drilling accuracy, penetration rate, and equipment smoothness. Stable accumulator response minimizes system fatigue and contributes to longer component life in harsh mining environments.

Inspect the ACCUMULATOR 3115 3451 81 for nitrogen loss, shell fatigue, leakage, or diminished damping performance. Replace 3115345181 immediately if pulsation increases or accumulator response becomes delayed. Follow OEM nitrogen precharge specifications and hydraulic bleeding procedures for correct installation.

Also indicated as 3115345181, 3115-3451-81, and ACCUMULATOR 3115345181, this hydraulic accumulator block is widely chosen for OEM-standard performance and good-price replacement options for ATLAS COPCO and EPIROC machinery.
