Product Overview
This high-performance accumulator diaphragm and piston cup seal is customized for Atlas Copco DP3100 heavy-duty hydraulic rock drill, a high-power drill rig drifter widely used in underground mining, tunnel excavation and large-scale rock engineering. The product integrates nitrogen energy storage diaphragm and hydraulic impact piston cup seal, fully meeting full overhaul and daily maintenance requirements of DP3100 hydraulic drifter.
Adopting thickened fabric-reinforced NBR rubber and high-hardness wear-resistant PU polyurethane as core raw materials, this sealing assembly features excellent nitrogen permeation resistance, ultra-high impact fatigue resistance, abrasion resistance and long-term anti-aging performance, serving as a perfect direct replacement for original Atlas Copco OEM sealing spare parts. It thoroughly solves typical failures including accumulator nitrogen leakage, cylinder internal oil leakage, hydraulic impact pressure attenuation and weak striking force, greatly extending the service life of DP3100 drifter under long-time heavy-load, high-frequency impact, violent vibration and high-dust underground harsh working conditions.

Key Selling Points
1. 100% OEM Standard Dimension, Direct Installation Without Modification
Fully matched with original Atlas Copco DP3100 drifter, consistent with OEM size, radian and installation positioning. No cutting, grinding or secondary modification needed. Suitable for daily routine maintenance, underground field overhaul and emergency breakdown repair, effectively reduce equipment downtime and manual maintenance cost.
2. Thickened Composite Special Material, Stable Sealing Under Full Working Conditions
The energy storage diaphragm adopts multi-layer fabric-reinforced nitrile rubber, strong tear resistance and excellent elastic recovery, resisting cracking after millions of high-frequency impact cycles; piston cup seal uses high-density cast PU material with outstanding anti-extrusion and wear resistance. The material resists nitrogen aging, hydraulic oil corrosion and fatigue deformation, maintaining stable sealing elasticity continuously from -40°C alpine mining to 130°C high-temperature deep tunnel construction.
3. Ultra-High Pressure & Anti-Impact Design, Eliminate Pressure Loss & Leakage
All sealing components pass strict 32MPa high-pressure endurance and long-cycle impact simulation tests. Curved bowl-shaped structure fits the inner cavity tightly, completely block accumulator nitrogen leakage and cylinder internal oil seepage, stabilize hydraulic striking pressure, guarantee constant impact power of DP3100 drifter under heavy rock breaking, continuous impact and strong vibration working scenarios.
4. Special Customized Structure for DP3100, Convenient Inventory & Maintenance
Independently developed according to DP3100 accumulator and piston sealing cavity structure, precise curved surface fitting. Single independent vacuum packaging, simplify spare parts classification and inventory management, shorten overall repair cycle and cut daily equipment operation and maintenance expenditure.
5. Multi-Round Strict Factory Inspection, Quality Reaches OEM Standard
Every set of diaphragm and cup seal undergoes air tightness leakage test, high-pressure durability test and cyclic impact aging test before delivery. All performance indicators meet original factory technical standards, providing long-term stable operation guarantee for underground mining and tunnel engineering hydraulic drill rigs.
6. Wide Application Scenarios for Heavy Rock Drilling
Specially matched for Atlas Copco DP3100 high-power hydraulic drifter, widely applied in heavy-duty rock engineering fields:
• Underground metal/coal mine: Underground roadway tunneling, stope rock drilling, ore blasthole drilling
• Tunnel engineering: Highway/railway mountain tunnel excavation, urban subway hard rock driving
• Hydropower project: Hydropower diversion tunnel, dam foundation rock drilling, slope anchoring drilling
• Quarry & open-pit mine: Large stone mining, open-pit rock blasting hole construction
• Infrastructure engineering: Mountain road excavation, underground pipe gallery rock breaking
