Working Principle of Reverse Circulation Drill Rig
The reverse circulation drilling machine operates on a unique fluid circulation system that sets it apart from traditional drilling equipment. Instead of pushing drilling cuttings up the annular space between the drill pipe and the borehole wall, it creates a vacuum effect that draws cuttings upward through the center of the drill string. This closed-loop circulation prevents cross-contamination of samples from different depths and allows for faster penetration rates. The system also reduces water consumption and minimizes environmental disturbance on the job site, making it a more sustainable choice for many projects.
Reverse Circulation Drill Rig Application Areas
- Mineral Exploration: Delivers undisturbed, depth-specific core samples that enable geologists to accurately map mineral deposits, assess resource volumes and plan extraction operations with precision.
- Geotechnical Engineering: Collects reliable soil and rock data for foundation design, slope stability analysis, dam construction, and large-scale infrastructure site characterization.
- Water Well Construction: Excels in drilling through gravelly, sandy or alluvial aquifers where conventional methods often encounter collapse or sample loss issues, producing high-yield, long-lasting water wells.
- Foundation Piling & Ground Improvement: Supports deep foundation projects, soil stabilization works and ground reinforcement for commercial buildings, bridges and industrial facilities.
- Environmental Monitoring: Facilitates underground water quality testing and soil contamination investigation by providing clean, uncontaminated samples from specific depths.
Features of the YG Reverse Circulation Drill Rig
The YG150RC reverse circulation drill rig combines power, precision and durability to meet the rigorous demands of modern construction and exploration. Its key features include:
- Robust Power & Mobility System: Powered by a reliable 125kW Cummins 6BTA5.9-C125 diesel engine with a maximum rotary speed of 2200rpm, delivering consistent performance during extended operation periods. The 9000kg heavy-duty crawler chassis provides exceptional stability on uneven terrain and slopes, with a 1.2km/h walking speed for efficient on-site movement between work zones.
- Industry-Leading Drilling Performance: The high-performance drill head generates 8000N · m of maximum output torque, with both continuous (30/60, 54/108rpm) and interval (62/124, 105/210rpm) rotation speeds to adapt to different rock types and drilling conditions. The efficient feeding system provides 45kN of thrust force and 65kN of lifting capacity, enabling smooth and efficient drilling operations up to the full 150m nominal depth.
- Integrated Operational Efficiency Features: Comes standard with an integrated pipe-puller device that delivers 30000N · m maximum torque and 40rpm rotation speed, with a 370mm hole-through diameter to handle pipe installation and extraction tasks quickly and safely. An 11kN first-layer pull force auxiliary winch with 60m rope capacity supports on-site material handling and auxiliary drilling operations.
- Wide All-Weather & All-Angle Adaptability: Functions reliably in ambient temperatures from -10°C to 38°C, with a full drill angle range of -10° to 90° and adjustable horizontal hole height from 1.85m to 2.8m, enabling vertical, horizontal and angled drilling to match diverse site layouts and project requirements.
