High-Pressure Hydraulic Accumulator Assembly | For HL500/HL510 DriftersEngineered to stabilize hydraulic pressure and store energy in high-demand drilling applications, this accumulator assembly ensures consistent performance in HL500/HL510-type hydraulic drifters.
Technical Specifications & DesignConstructed from ISO 6953 grade carbon steel with shot-peening treatment, the housing resists cyclic fatigue and mechanical stress, maintaining integrity under frequent pressure fluctuations. The piston-style design features a PTFE-coated seal (ISO 6194-1 compliant), achieving zero leakage at rated pressure (210 bar) and minimizing friction for responsive pressure regulation. The NPT 3/8″ threaded ports (ISO 7-1 compliant) enable quick integration with OEM hydraulic lines, reducing installation time by 30% compared to generic fittings.
Performance Advantages
Energy Storage Efficiency: Stores up to 1.5 L of hydraulic fluid, compensating for pressure surges during drill bit impact and reducing pump load by 15%.
Environmental Resilience: Operates reliably in -20°C to +80°C temperatures, with a zinc-chromate conversion coating (ISO 4520) providing 500+ hours of salt spray resistance (ASTM B117).
Safety Features: Burst pressure rating of 250 bar (119% of max operating pressure), compliant with ISO 6020/1 safety standards for hydraulic accumulators.
Applications
Mining Operations: Ideal for underground hard-rock mining, where it stabilizes pressure in drill feed systems during long-hole drilling (30+ meters depth).
Quarrying & Construction: Supports surface quarry drills and foundation rigs, reducing hydraulic system wear in high-vibration environments like limestone or granite drilling.
Industrial Maintenance: A direct replacement for worn accumulators in HL500/HL510 drifters, restoring pressure stability and extending pump/motor service life by 20%.
