The Drilling Project Services Shocksub (DPS SHOCKSUB) was designed and developed in Southern Africa and provides optimum protection to the rotary head and mast structures of all rotary drills. The DPS shocksub element minimises both the vertical and rotary vibrations, and impact loading that are created during drilling and assists in maintaining the drillbit more uniformly in contact with the formation being drilled. The dampening effect of the shocksub assembly reduces the shock loads and vibrations which are transmitted up the drill column to the drive train of the machine, thereby minimising drill maintenance and gearbox damage.
Reduces the amount and amplitude of vibrations transmitted from the drill string to the drive head, resulting in:
The shocksub assembly also compensates for the drill pipe deflections caused by misalignment, resulting in:
The shocksub assembly maintains a more constant load on the drillbit and absorbs vertical vibrations and the torsional stresses encountered during normal drilling operations, resulting in:
1. Machine make and model.
2. Hole size being drilled.
3. O.D. of drillrod.
4. Top connection details for shocksub.
5. Bottom connection details for shocksub.
6. Maximum acceptable length of complete unit.
7. Breakout slots or flats required on bottom connection of shocksub unit.
PLEASE ENSURE THAT THERE IS SUFFICIENT SWING CLEARANCE TO ACCOMMODATE THE CHOSEN UNIT.
