Applications

KW350 model Multi-Function Geothermal Water Well Drill Rig is mainly used for drilling water wells ,ground source heat pump wells and other uses of the borehole. The rig can drill work on different Geological formations, drilling hole diameter is larger, the max hole depth of up to 350 meters. Unique deep hole axial compression adjustable system to Adjust impetus, deep hole drilling reduces the rotation resistance. Have two-stage telescopic /shrink carriage, use 6 m drill pipe, reducing the times of change drill pipe.

The top-mounted driving head principal shaft has a great drift diameter, which is suitable for many kinds of construction work such as slurry drilling, air drilling, and air foam drilling, meeting the demands of well-drilling in different terrain strata.

 

Performance Characteristics

  • Equipped with 92KW Yuchai brand turbocharged engine, strong power.
  • Patented design composite boom, double cylinder lift, long stroke, large tonnage.
  • The main boom of each rig is equipped with a stopper to protect the cylinder.
  • Drilling machine chassis: professional excavator chassis ,durable,heavy bearing capacity,wide chain plate, less damage to hard road.
  • Parallel gearbox design, separate oil pump, sufficient power supply, reasonable distribution, unique design of hydraulic system, simple maintenance and low cost.
  • The travel motor is equipped with reducer, durable and long service life.
  • Fast distribution valve: the speed of three gears up to 66-135 rpm, basically achieve the dual-use function of water and air.
  • Each hydraulic hose is covered with soft management set to make the hose last longer.
  • The rig power is driven by the diesel engine, and the rig's walking, turning, propulsion, lifting, outriggers, and unloading rods are all controlled by hydraulic pressure.
  • The rig's walking is a crawler-type self-structure, which is easy to move. Its rubber crawler-type chassis makes it easy to walk in the city and the courtyard, and it is not easy to damage the ground.
  • High and Strong hydraulic legs allow quick and stable adjustment of the rig's body level for easy loading and unloading and shifting positions.  
  • Dedicated wellhead setting provide a the certain center for drilling to ensure the  vertical opening and positioning accuracy.
  • Mechanical positioning of the carriage and frame improves the stability of the carriage.
  • The pneumatic system has a custom oil injector that lubricates the impactor, effectively increasing the life of the impactor.
