JRC300 RC Hydrauclic Reverse Circulation 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.

 

Advantages

1. One machine with multiple functions, realizing fast switching of various drilling processes;

2. The power head has a wide range of speed adjustment, large torque, meeting different technological requirements, and convenient high and low speed adjustment;

3. The control console is reasonably arranged, and the power head speed is digitally displayed for easy operation;

4. The hydraulic system adopts load sensing control system and imported components, which saves energy and has high reliability;

5. The mast has variable angles and overall sliding to achieve landing support and enhance the stability of drilling;

6. The main drawworks is imported from the United States, which can realize the function of drilling while drilling;

7. The crawler is easy to load and move, which is convenient for overall relocation and quick installation.

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 provided 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.

7. The walking system is a self-walking system, convenient for moving, which 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 extension system, which ensure the guide could moving toward the drilling surface, to keep the balance of the guide.

11. Gradienter, angle label 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.
