The Working Principle Of Water Well Drilling Rig

Its working principle is: under the action of atmospheric pressure, the circulating fluid flows from the sedimentation tank through the backwater ditch to the bottom of the well along the annular gap of the well hole. At this time, the rotary table drives the drill pipe and drives the drill bit to rotate for drilling. The negative pressure established by the suction sucks the debris mud into the inner cavity of the drill pipe, then rises to the tap, and is discharged into the sedimentation tank through the mud pump. The precipitated circulating fluid continues to flow into the well hole, and the cycle repeats, forming a reverse circulation drilling work.
