Kazakh Taraz fully hydraulic rope core drilling rig 1000 project

Performance and advantages of full hydraulic power head surface core drilling rig

1. Hydraulic system:

The imported parts of the hydraulic system have a high proportion, and the main control and execution systems of the main and auxiliary systems are the original imported hydraulic parts from Europe (most of the other manufacturers only the main pump and individual control system parts are imported, and the level and use proportion of the imported parts are low).

2. Main pump and feed pump oil route:

The most advanced load sensitive pump is adopted to save energy, reduce the construction cost, and increase the pressure oil filter to improve the service life of hydraulic components and reduce the failure rate.

3. Feed into the system:

1), the rig power head is not directly into the cylinder, reduce the intermediate transmission components, so as to reduce friction loss,

 Can also reduce the daily maintenance, at the same time by reducing the intermediate link, into the oil cylinder into the drilling tool into the force can be more accurate reflection;

2) Accurate drilling pressure control can more effectively reduce the accident in the hole in the drilling process.

4. New ways to add stress:

Advanced pressure and decompression drilling system (balance principle). First, balance the weight of the drill pipe, and the force applied to the drill bit is zero, and then pressure the drill tool through the oil cylinder, by adjusting the size of the pressure valve, timely and accurately read the size of the inlet and outlet. Advanced decompression drilling system not only improves the life of the bit, but also improves the drilling efficiency, so the operation is very easy and convenient.

5. Power head:

1) The drill adopts a 4-gear stepless gearbox, wide speed range, the power head torque matching is more reasonable, can achieve the different drilling process to speed requirements;

2) The drill has installed the speed sensor on the gearbox, and the reading is accurate and reliable;

3) Increase the floating function of the power head, the power head floats upward when unloading the buckle, more effectively protect the drill pipe thread, prolong the service life of the drill pipe, and save the construction cost;

4), the power head increases the hydraulic automatic sideslip function, the function is mainly to reduce manpower, improve work efficiency, so as to greatly reduce the labor intensity of the construction personnel.

7. Main roll:

The main winding of the rig increases the speed regulation function, and adjusts the displacement of the hydraulic motor by proportion, so as to adjust the winding and rope out speed of the winch, which greatly improves the drilling efficiency.

8. Rope core and roll:

The rig auxiliary winding increases the rope arrangement mechanism to prevent the wire rope winding, and can improve the service life of the wire rope.

9. Mast:

1) The mast and mast slide are processed on the longest 11 m planer platform in China, with high accuracy, which reduces the swing of the power head and greatly increases the overall stability of the drilling rig;

2), the drill hole plate and hinged support is to make the mast force through the hinged plate better not ground contact, increase the stability of the mast;

3) When the mast slip stroke of the rig is 1.1 meters and the drilling Angle reaches 45°, the mast can be directly grounded, improving the stability of the rig and reducing the possibility of major safety accidents;

10. Hydraulic hose and pipe joint:

For imported products, effectively reduce the oil leakage point, reduce the maintenance time.

11. Stepless speed regulation function of mud pump:

The rig adds a load-sensitive plunger pump and a throttle valve to refine the regulation of the mud pump flow. By drilling load sensitive plunger pump and throttle valve, the flow of mud pump can be continuously adjusted at each gear of the mud pump. The flow control of mud pump can meet the needs of various centering drilling processes such as stone rope centering drilling, especially suitable for impact rotary drilling process.

12. Mud mixer:

The rig is equipped with stirers with original American imported motors
