Special-shaped multi-edge grooved drill pipe-main advantage analysis
2. Analysis of Main Advantages The rotation of this series of drill pipes in loose cinder can cause vortex flow. Pulverized coal deposited at the bottom of the borehole is raised by the edge of the drill pipe, and the pulverized coal in the hole is always in motion, thus avoiding accumulation and blockage of pulverized coal in the borehole. At the same time, the discontinuous spiral groove on the surface can assist the cinder to be transported outward. Therefore, it is not easy to cause the phenomenon of drilling and sticking. The principle of rotating a shaped multi-edged cross-sectional rigid body in loose cinder causes vortex flow along the axis of the rigid body.
