JRC200 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 .
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 provice 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 cystem, winding and so on.
6. Axes pressure,feed speed,rotary speed is adjustable.
7. The walking system is a self-walking system,convient for moving,wich could install four hydraulic leg,when load on truck,it doesn’t need hiking up,it can load on truck directly.
8. Four hydraulic leg use for keep the balance of the drilling during working.
9. The sub winding could hoisting Max.1ton drilling tool,it also could help to rod change.
10.The guide(mast) could working in 45°-90°,guide have a extention system,which ensure the guide could moving toward the drilling surface,to keed the balance of the guide.
11. Gradienter,angle lable and centralizer to ensure the precision accuracy of hole.
12. The air system have a special lubrication system to lubricating the hammer to extend the service life.
In our after sales service system, We establish perfect control system strictly according to ISO-9000 series, in this system, technology date and problem solve solution and preventive measures will be provided in any maintain project, all the spare parts will be used in new OEM products with installation instructions, packing list, manufacturer's instruction, qualification and Warranty certificate.
We provide "one equipment & one case, endless service, namely the after sales service begin from the order confirmation, last for the working life of the equipment.
