Reverse circulation multifunctional drilling rig is a new efficient, environmentally friendly, and multifunctional tracked drilling rig.lt adopts the latest RC drilling and mining technology from abroad, and drilling dust can be effectively collected through dust collectors, avoiding environmental pollution. lt can also be collected and discharged through a cyclone separator, which can be used for sampling and analysis work in geological exploration departments.lt is the preferred equipment for geological exploration drilling and other deep holes.
This drilling rig can use compressed air reverse circulation down-hole drilling on various formations. The lifting of the drilling rig frame, compensation of the drilling frame/multi angle drilling unloading of the drill pipe rotation and feeding,support legs ,hoisting,walking and other movements are all achieved by the hydraulic system, greatly reducing labor intensity, improving construction efficiency and engineering quality.
It is a geological exploration drilling, drilling wells, monitoring wells, ground source heat pump air-conditioning and other deep hole of choice for equipment.
(1)Reliable Performance Basing on the guideline of purchasing the critical auxiliary equipment internationally, the diesel engine,
the hydraulic pump, the main valves, the motors, crawler reducers and key hydraulic spare parts are all adopted famous brands products at home and abroad.
(2)High Efficiency With big torque, high power unit allocation and with reasonable structure design and advanced operation method
, all these guarantee the drill rig's high operation and performance efficiency.
(3)Environmental Protection With lower pollution discharge of diesel engine, professional noise reducing design, the drill rig is
suitable for urban operation and performance.
(4)Energy Saving Adopting the advanced load sensitive control technique, the drill rig has reduced the power consumption and heat
generation to the lowest level. With an elegant outline, compact structure, reliable performance and operation easily, it should be the priority equipment to be selected in the full hydraulic core drill rig of present domestic market.
