High-Impact Percussion Kit for Hydraulic DriftersEngineered to deliver consistent impact energy in demanding underground drilling environments, this percussion kit optimizes the performance of hydraulic drifter systems in hard-rock applications.
Technical Components & SpecificationsThe kit includes:
- Impact Piston: Constructed from ISO 898-1 grade quenched and tempered alloy steel (tensile strength ≥1000 MPa), heat-treated to HRC 45–50 for wear resistance during high-frequency impacts (30–45 Hz).
- Dual-Layer Seals: Primary and secondary seals (NBR material, ISO 6194-1 compliant) create a pressure-tight barrier, resisting leakage at 110% of rated pressure (275 bar) and filtering out particles ≥5μm.
- Buffer Spring: Chrome-plated alloy steel spring (ISO 230-2 certified) with a fatigue life of 1 million cycles, absorbing shock to reduce stress on connected components.
Performance Advantages
- Energy Transmission Efficiency: Transmits 92% of hydraulic energy to the drill string, maintaining impact force consistency even in abrasive conditions (e.g., quartz-rich rock formations).
- Vibration Resistance: Dynamic balance testing (ISO 1940 G6.3 grade) ensures minimal lateral vibration, extending the service life of drill bits and tool joints by 25%.
- Environmental Adaptability: Operates reliably in extreme temperatures (-30°C to +100°C) and high humidity (95% RH non-condensing), meeting IP67 ingress protection for underground use.
Applications
- Underground Hard-Rock Mining: Ideal for deep-hole drilling (60+ meters depth) in gold, copper, and iron ore mines, where consistent impact energy is critical for breaking dense rock formations.
- Tunnel Boring & Construction: Supports hydraulic drifters in tunnel excavation, delivering sustained impacts for limestone and granite drilling while minimizing maintenance downtime.
- Quarry Exploration: Enhances productivity in surface quarries by maintaining drill penetration rates in medium-hard rock (uniaxial compressive strength ≤200 MPa).
