Hydraulic High Performance DTH Impactor. High Wear Resistance: Piston and cylinder block made of high-strength alloy steel with hardness HRC45-50, increasing wear resistance by 30%. Fast Response System: Built-in ring valve plate ensures response time under 5ms for stable high-frequency impact. Central Exhaust Design: Discharges air through drill bit center to remove rock powder and reduce repeated crushing. Overload Protection: Automatically shortens piston stroke when drilling resistance is too high to prevent equipment damage. Wet Rock Drilling: Supports high-pressure water injection to reduce dust pollution and meet environmental requirements. Deep Hole Capability: Capable of drilling water wells up to 300 meters deep and penetrating granite layers.
