Product selling points

Positive and negative axial pressure adjustment

The best impact efficiency of all kinds of impactors has the best axial pressure and rotation speed. In the process of drilling, with the increasing number of drill pipes, the axial pressure of the impactor is also increasing. Therefore, in the construction, the positive and negative axial pressure valves are adjusted to ensure that the impactor can obtain more matching axial pressure. At this time, the impact efficiency is higher.

Advantage of water well drilling rig:

1. Construction technology: mud positive circulation drilling, mud reverse circulation drilling, air DTH hammer drilling, air lift reverse circulation drilling, hydraulic DTH hammer drilling

2. In the production stage, the strength of materials we adopt greatly exceeds the specifications and requirements of parameters and actual use, leaving fault-tolerant space for operation, achieving the goal that all parts are not always in full or overloaded working conditions, fundamentally reducing the probability of failure of parts, reducing construction losses and reducing implementation. Labor cost. And install protection, automation equipment, protection equipment, to maximize security and improve operability.
