Introduction To The Working Method Of Top Hammer Drilling Tools

Body

        The working process of DTH Drill Pipe is inseparable from the use of the pump, which uses the pump for reverse circulation operation. Under the action of atmospheric pressure, the circulating fluid flows from the sedimentation tank to the bottom of the well along the annular gap of the well hole through the backwater ditch. At this time, the rotary table drives the drill pipe and drives the drill bit to rotate for drilling, which is sucked by the mud pump. The negative pressure sucks the debris mud into the inner cavity of the drill pipe, then rises to the tap, and is discharged into the sedimentation tank by the mud pump, and the precipitated circulating fluid continues to flow into the well hole. This repeats and forms a reverse circulation drilling work. Mud or water enters from the drill pipe and flows out from the wellhead, which is a positive circulation drilling machine. Mud or water is sucked out from the drill pipe and flows in from the wellhead, which is a reverse circulation drilling rig. Positive and negative circulation refers to the circulation method of the drilling fluid in the drilling machine. Top Hammer Drilling Tools will produce muck, slag, etc. when drilling, which can be carried out by the mud through the positive and negative circulation.
