(hydraulic rotary drilling)
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:
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.

A: Hydraulic rotary drilling is a method that uses high-pressure fluid to power a rotating drill bit, enabling efficient penetration through hard rock or soil. It is commonly used in mining, construction, and geotechnical exploration.
A: A hydraulic rotary drilling machine uses hydraulic motors to rotate the drill bit while pumping fluid to remove cuttings. This system ensures precise control and high torque for demanding drilling tasks.
A: Hydraulic rotary drilling rigs offer high power output, adaptability to varying ground conditions, and reduced mechanical wear. Their modular design also allows for easy transportation and setup.
A: These rigs are widely used in oil and gas exploration, water well drilling, foundation piling, and mineral exploration. They excel in projects requiring deep or large-diameter boreholes.
A: Regular inspection of hydraulic fluid levels, filter replacements, and seal checks are critical. Proper lubrication of rotating components and timely replacement of worn drill bits ensure optimal performance.
