Applications

The KT7C high air-pressure down the hole drill rig for open use is an advanced drilling device integrating down the hole drilling system and screw air compression system, typical of compact structure, excellent integrity and mobility. Equipped with the single-stage high air-pressure screw host, the flow stands at 13m3/min and air pressure at 1.7MPa, thereby proving high-valued parameters. The drill rig provides strong power for the high air-pressure down the hole hammer and the drilling speed is higher than that of middle air-pressure drill rig by 20%-50%. It is characterized by energy conservation, efficiency, safety, environment-friendliness, flexibility, simple operation and stable performance, etc. Equipped with the Yuchai China stage III engine, the drill rig meets national standards for emissions and environment.

Performance Characteristics

  • 1.The drilling rig is equipped with screw air compressor and adopts the high air pressure pneumatic impact. The drilling rig is with high efficiency, low energy consumption.
  • 2. The drilling rig is equipped with hydraulic dry integrator to collect dust and reduces the pollution of the environment.
  • 3. The drilling rig is equipped with hydraulic manipulator, the drill pipe warehouse which disassemble the drill pipe and the floating joint which protect thread of drill pipe .One can disassemble the drill pipe.
