Working Principle of the Small Water Well Drilling Rigs:
The drilling machine works by pumping reverse circulation. Its working principle is: under the action of atmospheric pressure, the circulating fluid flows from the sedimentation tank through the return ditch to the bottom of the well along with the annular clearance of the good hole. At this time, the rotary disk drives the drill pipe to drive the drill bit to drill. The negative pressure established by mud pump suction inhales the debris mud into the inner cavity of the drill pipe, then rises to the faucet, it is discharged into the sedimentation tank through the mud pump, and the circulating liquid after the sediment continues to flow into the good hole so that the drilling process of the reverse circulation is formed.
