Unidrill Power Head for Rotary Drill Rig
By Li Chenyu / hcfire360 October 2020
The power head is the core component of the rotary drilling rig, which provides torque and pressure for the drilling rig; it provides guidance for the drilling of the drill pipe; and provides high and low frequency instantaneous impact for the drilling of the drill bit.
Unidrill power head advantages:
- The structural parts are reliable and effective in strength, ensuring stable construction and reliable hole formation;
- The sliding ear installation of the carriage is free of assembly adjustment;
- The slide plate is easy to disassemble and maintain;
- Modularization of steel wire rope and cylinder pressure configuration,
- Maintenance of pressurized pulley without dismantling steel wire rope;
- The buffer device has an anti-torsion function;
- Buffer mechanical limit effective protection buffer device and structural parts;
- The buffer is far superior to its counterparts, works more smoothly, and effectively protects structural parts;
- The fixing method of the key plate is easy to replace and there is no risk of oil leakage;
- The length of the key plate is better than that of peers, and the drill pipe has better guidance and better force;
- The sleeve interface is modularized, and a full set of pipework methods can be switched;
- The sleeve can be matched with a small size drill pipe downwards;
- Sleeve customized bearings, improve accuracy, impact resistance, improve the structural strength and sealing of the box
- Open the cover under the box to improve the strength, rigidity, tightness, processability, replacement and maintenance;
- The tank body, case cover, sleeve end cover, and gear shaft lower cover are all equipped with oil drain to avoid blind areas for oil change;
- The combined sealing structure will never enter the sand and prevent oil leakage;
- It can match all construction work modes of host manufacturers.
