High-Pressure Nitrogen Gas Accumulator for Hydraulic Rock Drills
Engineered for extreme underground mining conditions, this accumulator ensures reliable pressure stabilization in high-vibration hydraulic rock drill systems. Constructed with a carbon steel shell and nitrile rubber diaphragm, it withstands continuous dynamic loads while resisting abrasion and corrosion in harsh environments .

 

Technical Specifications & Design
The accumulator features a 5 L nominal volume and 200 bar maximum working pressure, adhering to ISO 16028:2016 dimensional and performance standards. Its hot-dip galvanized coating (54 μm thickness) passes 240 hours of salt spray testing (ISO 9227), ensuring long-term durability in wet or corrosive mining environments . The precharge pressure of 50 bar (nitrogen gas) optimizes energy storage and release efficiency, while the ±0.5% volume tolerance guarantees precise pressure regulation .

 

Performance Advantages
  • Vibration Resistance: Engineered to maintain dimensional stability in high-frequency oscillating systems, minimizing wear in critical hydraulic connections.
  • Corrosion Protection: Hot-dip galvanized coating exceeds industry standards, extending service life by 30% compared to standard electroplated coatings .
  • Precision Fit: Dimensions adhere to ISO 16028:2016 tolerances, ensuring compatibility with standard hydraulic system components.
  • Ease of Installation: Clear torque specifications (20 N·m for inlet valve) streamline maintenance processes .

 

Applications
  • Underground Mining: Critical for stabilizing pressure in rock drills used in tunnel boring and ore extraction.
  • Heavy Machinery: Used in excavators and loaders to buffer hydraulic shocks and reduce energy consumption.
  • Industrial Hydraulics: Supports presses and material handling equipment, ensuring consistent pressure supply in repetitive motion tasks.
