The drilling project is of course with the most professional machinery and equipment, that is the water well drilling rig, which is characterized by advanced structure, convenient assistance and short use time. Its good performance greatly enhances the speed and efficiency of well drilling, especially in areas where agriculture is more popular, due to the demand for agricultural water, well drilling as well as well drilling rigs are more widely used. Now Relied Group will briefly introduce the use of water donut drilling rigs for you.

The water well drilling rig cannot work without the use of a pump, which is used to perform a reverse circulation operation. Under the action of atmospheric pressure, the circulating fluid flows from the sedimentation pond to the bottom of the well via the return trench along the annular gap of the borehole, because the rotary disc at this time drives the drill pipe and drives the drill bit to rotate for drilling , the negative pressure established by the mud pump pumping draws the debris mud into the inner cavity of the drill pipe, which then rises to the tap and is discharged into the sedimentation pond by the mud pump, and the circulating fluid after sedimentation continues to flow into the borehole, and so on and so forth, forming a reverse circulation of drilling work. Mud or water enters from the drill pipe and flows out from the wellhead for positive circulation drilling rig. When mud or water is sucked out of the drill pipe and flows in from the wellhead, the drilling rig is reverse circulation. The positive and negative circulation refers to the way the drilling fluid is circulated in the drilling rig. The drilling rig bit produces slag, slagstone, etc. when drilling, which can be brought out by the mud through positive and negative circulation.
