JRC300 Reverse Circulation(RC) Drilling Rig
JRC300 reverse circulation drilling rig is a new multi-purpose, high-efficiency, environmental protection, multi-track-type rig, which uses the latest foreign gas lift reverse circulation drilling technology, rock dust can be effectively collected through a dust collector to avoid environmental pollution.You can also collect slagging cyclone separator can be used in geological prospecting department of sampling analysis.It is a geological exploration drilling, drilling wells, monitoring wells, ground source heat pump air-conditioning and other deep hole of choice for equipment.
The drilling rig can be used in a variety of compressed air on the ground hole reverse circulation drilling. The lifting system,guide compensation, drill pipe loading and unloading, rotation and feed, legs, winch, walking and other system to achieve all of the hydraulic system to significantly reduce the labor intensity and improve the efficiency and quality of construction .

Application Characteristics
1.Diesel engine mounted hydraulic system, all the system include the walking, rotation, feed, lifting, Leg, lifting, compensation system, rod change is hydraulic.
2:Reverse circulation system working together with DTH technology, air compressor provide pressed air for impact and dust collect.
3.During working, use the reverse circulation hammer, double tube, pressed air enter between two tube and dust out from the inner tube.
4.Also it's available to positive circulation use normal drilling tool.
5.The working system composed of feed system, guide(mast),rotary head, compensation system, centralizer, rod exchange system, winding and so on.
6.Axes pressure, feed speed, rotary speed is adjustable.
