The use of water well drilling tools improves the speed and efficiency of drilling wells. In areas where agriculture is more popular, due to the demand for agricultural water, well drilling and drilling machines are widely used. So, in which way do water well drilling tools work?
The working process of water well drilling tools is inseparable from the use of pumps, which are used 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 good hole through the backwater ditch, because at this time the turntable 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 good hole. This repeats the cycle, forming 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 machine. Positive and negative circulation refers to the way the drilling fluid circulates in the drilling machine. When the drill bit of the drilling rig drills, it will produce muck, debris, etc., which can be carried out by the mud through the positive and negative circulation.
