Product Knowledge: The Importance of Hydraulic Seal Kits

The part number 9120079007 typically designates a service or seal kit essential for the high-pressure hydraulic components within an Atlas Copco Rock Drill. The function of these seals is critical: they prevent internal and external leakage, maintain system pressure, and protect sensitive moving parts from contamination. A failed seal kit leads to pressure loss, reduced percussion power, increased oil temperature, and eventual system failure, highlighting why choosing a reliable genuine quality replacement part is paramount for longevity and performance.

Mining Equipment Troubleshooting: Sandvik Drill Rig DT1131i Hydraulic System Fault

Fault: Reduced penetration rate and excessive noise from the Rock Drill on a Sandvik DT1131i Jumbo Drill, despite normal engine RPM.

Possible Cause & Solution: This is often an indication of a hydraulic pressure issue, frequently caused by wear in key components such as the accumulators or internal seals.

  • Check 1 (Accumulators): Verify the pre-charge nitrogen pressure in the rock drill accumulators. Low pressure can lead to erratic percussion and noise. Recharge or replace faulty accumulator bladders (we supply Sandvik drill rig spare parts for accumulators).

  • Check 2 (Internal Leakage): Internal bypass leakage within the drill or feeder cylinder, often due to degraded seals (like the one compatible with 9120079007 but specific to the Sandvik drill). The solution is to replace the relevant hydraulic hammer repair kit.

  • Final Action: Use high-quality replacement parts from Hugeminer for lasting repairs and reduced downtime for your underground mining equipment.
