OEM Color Deep Well Drilling Equipment High Speed ST400
well drilling equipment high speed
,high speed drilling equipment for water well
,hydraulic well drilling equipment
The Water Well Drilling Rig adopts steel crawler chassis and has strong cross-country ability with excellent mobility. The rig is equipped with large torque hydraulic motor and large bore hydraulic cylinder, making it especially suitable for water intake projects in mountainous rock stratum. It offers advantages of large diameter, deep drilling, fast footage, flexibility and high efficiency.

The working process of water well drilling rig is inseparable from the use of pump, which is used for reverse circulation operation. Under the action of atmospheric pressure, the circulating liquid flows from the sedimentation tank through the return 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 of the mud pump sucks the debris mud into the inner cavity of the drill pipe, then rises to the faucet and is discharged into the sedimentation tank through the mud pump. The precipitated circulating liquid continues to flow into the well hole, which goes on and on, forming reverse circulation drilling work.
Mud or water enters from the drill pipe and flows out from the wellhead in a positive circulation drilling machine. Mud or water is sucked out from the drill pipe and flows in from the wellhead in a reverse circulation drilling machine. Positive and negative circulation refers to the circulation mode of drilling fluid in the drilling machine, which brings out muck, slag and stone produced during drilling.
