Deep Borehole DTH Drilling Rig – 350m Depth Water Well Machine for Professional Use
Product Description
Engineered for superior drilling performance, the RCF350C rig achieves remarkable 350-meter drilling depths with 350mm bore diameter capability. Its innovative design allows seamless integration with either mud pumps or air compressors to handle diverse geological formations - from soft alluvial soils to challenging hard rock layers.
The system incorporates intelligent pressure regulation technology that automatically adjusts axial pressure through positive/negative pressure valves. This ensures optimal impact efficiency throughout the drilling process, even as additional drill pipes are added. The advanced hydraulic system delivers consistent power transmission while maintaining precise control over drilling parameters.
Key advantages include:
Adaptive pressure regulation for maximum impact efficiency
High-torque rotary system for improved drilling performance
Modular configuration for various operational requirements
Robust construction for extended service life in tough conditions
Ideal for agricultural, industrial and municipal water supply projects, the RCF350C represents the perfect balance of power, precision and reliability for professional drilling operations. Its optimized impact mechanism and pressure control system guarantee efficient penetration rates while reducing energy consumption.
