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.
