XDEM ZJ-80 Portable Water Well Drill Rigs Self-propelled Tractor Mounted Water Well Drilling Machine

Main Features of the Water Well drilling mchine

Drilling machine mainly consist of diesel engine, friction clutch, gearbox, transfer case, transmission shaft, mud pump, clarified water pump, vacuum pumps, rotary table, swivel, hoister, hydraulic systems, control mechanism , mast, drilling tool, frame and other components.

Working principle of the water well drilling machine:

Water well rig works through pump-absorption reverse circulation. Under the pressure of atmospheric, the circulating fluid from the sedimentation tank through the return ditch along the annular gap between the borehole flow to the bottom of the well, when the rotary table drive drill pipe, drive bit drilling, mud pump suction creat the negative pressure inspire the debris cavity into the drill pipe iumen, then rose up to the swivel, through the mud pump into the sedimentation tank. The post precipitation circulating liquid continues to flow into the borehole, again and again, forming a reverse circulation drilling work.
