Rotary-drilling with reverse circulation CBM universal Drilling Rig TDR -50
The TDR -50 universal drilling rig enables each user to drill with the following methods, with borehole diameters of 3.5 ″to 47″and drilling depths up to 1 200m.
●Rotary-drilling with direct circulation
●Rotary-drilling with reverse circulation
●Percussion core drilling (ram coring)
●Wire-line core drilling
●Down-The-Hole hammer drilling
●Direction deviation drilling
TDR servies rig can be use for shallow oil and gas, coal bed methane drainage, geothermy, explotation of mine and large diameter deep water well application, also can be use for gas emissions of colliery and down hole of rescue.
TDR-50 Full Hydraulic Multifunction Top Drive Drill Rig
1. Unite Engine
Diesel engine, 6 cylinders, in-line, 2 valves, turbocharged intercooled; Separate cylinder heads, frame block; Using mechanical high-pressure injection technology for fuel system.
The crankshaft of diesel engine provides power for hydraulic pump through flexible coupler (made by KTR in Germany).
Model WD10G330E211 Diesel engine
Power 330 HP (243 Kw)@ 2200 RPM
Max.torque 1250 Nm@ 1500 RPM
Displacement 9.726 L
Min Fuel Consumption 210g/kw h
2. Hydraulic System
Four hydraulic pumps, three variable displacement piston pumps and one fixed displacement
hydraulic pumps, all together provide power for the rig. The hydraulic system is an open circuit with proportional control valve and completely circuit filter unit. The filter element can be replaced.
The heat dissipation of hydraulic is from forced air cooling. Variable displacement piston pump and proportional control valve of rotating and feeding system are load-sensitive designed,
which controls the flow of pump as required. All hydraulic branches are protected by overflow valve.
3. Outriggers and Mast Tilt
Outrigger is made by heavy square steel pipe, both front and rear cylinders are connected with the drill mounting. There are locking devices at both loading and travel position. Each outrigger could position all by itself.
The cylinder of mast has buffer end, which could reduce shock when it goes up and down, and makes it more stable. The control valve could change speed as needed.
4. Control Panel
Arc-swing panel located at the left side, and it can retract under the mast when transporting.
Control panel consists all the apparatus and driller position.The dash board consists: water-thermometer, tachometer, oil manometer, pressure gauge of rotating system, pressure
gauge of feeding system, pressure gauge of drilling system, pressure of drilling, Pressure
of assistant pump etc.
5. Telescoping Mast
Telescoping mast provides much more travel distance and height for the drill head, and
shortens the length of main machine in transportation. The sliding cylinder helps the mast
with travel distance up to 3.65 m, and makes it firmly contact the ground, accordingly,
minimizes the force of drill mounting.
Fully Expanded:62 feet (18.9 m)
Fully Retracted:39.4 feet (12 m)
6. Feeding System
Top drive head is driven by hydraulic cylinder and chain. When it is rising, the upper end of
mast could extended at the ratio of 1:2, the max length of head unit is about 46 foot (14.02m)
Capacity of pull back force 110 230 lbf (50 000Kg)
Capacity of pull down force 26 455 lbf (12 000Kg)
Max. Pull down speed 80m/min
Stroke of mast slip 3.65m
7. Safety System
Hydraulic system of mast is equipped with safety hydraulic valve, when something goes wrong
with hydraulic system and the rotate unit is drilling down out of control, the safety hydraulic
valve will lock the head unit, thus stops it from drilling down and avoids an accident.
8. Slow-Feeding Drill-Up Valve
The operator could control the pressure accurately through slowly feeding drill-up.
9. Top Drive Head
Top drive head suits for tricone bit, DTH hammer, PDC Dill bit and diamond bit which meets
special demand of rotate speed and torque during work. The 4-shift Gearbox using spur gear
drive, oil bath lubrication. Hydraulic Motor and gearbox could provide for much high speed
and torque to be adjusted.
The angle of rotate unit could be adjusted as needed, ranges from 0º(vertical)--90º.
Internal diameter of faucet core shaft: 76.2 mm
11. Power Wrench
The tongs are designed and manufactured according to SY/T5074 standard and API Spec 7K” Specification for Drilling and Well Servicing Equipment”.
Size Rang 3 1/2 ″coupling - 8″body
