Deep Borehole DTH Drilling Rig – 350m Depth Water Well Machine Full Hydraulic Operation
Product Description
Designed for superior drilling performance, the RCF350C rig can drill holes up to 350 meters deep and 350 mm in diameter. Its innovative design integrates seamlessly with a mud pump or air compressor, enabling it to operate in a wide range of geological formations, from soft alluvial soils to complex hard rock formations.
The system uses intelligent pressure control technology to automatically adjust the axial pressure through a positive/negative pressure valve. This ensures optimal impact efficiency throughout the drilling process, even with the addition of drill rods. The advanced hydraulic system provides constant power transmission, ensuring precise control of drilling parameters.
Key benefits:
Adaptive pressure control for maximum impact efficiency
High torque rotary system for improved drilling performance
Modular configuration to meet different operating requirements
Rugged design for longer service life in harsh conditions
Ideal for agricultural, industrial and municipal water supply projects, the RCF350C achieves the perfect balance of power, precision and reliability in professional drilling operations. Its optimized impact mechanism and pressure control system ensure efficient penetration and reduce energy consumption.
