Understanding Hydraulic Rotary Drilling Fundamentals

Hydraulic rotary drilling systems utilize high-pressure fluid circulation to achieve superior penetration rates compared to conventional methods. Modern hydraulic rotary drilling
machines operate at 120-350 RPM with torque outputs exceeding 12,000 Nm, enabling efficient borehole creation in granite, basalt, and other challenging formations.

Key operational components:

• Dual-pump hydraulic systems delivering 500-800 L/min flow rates
• Advanced drill pipe threading technology (API 5DP standard)
• Automated pressure compensation systems (±2% accuracy)

Technical Superiority in Geotechnical Applications

Field tests demonstrate hydraulic rotary drilling rigs achieve 40% faster penetration rates than mechanical alternatives in 80 MPa compressive strength rock. The technology's adaptive pressure control reduces bit wear by 28%, extending tool life to 1,200-1,500 operational hours.
