Water well rotary drilling rig is the most common drilling method at present, divided into Rotary well drilling rig and Reverse well drilling rig.
The water well rotary drilling rig is to drive the drill rotating through the rotary mechanism. Drill bits fit to the drill pipe end and cut soil or grind rock into pieces. The high-pressure mud pump will flush the medium (water, drilling flushing fluid), and pressure the medium into the drilling hole, and the slag will come our from the drilling hole.
According to the power transmission, a rotating well drilling rig can be divided into the powerhead, turntable drilling and underground power drilling.
Check the types of water well drilling rig we have.
The powerhead of a good drilling rig is hydraulically powered from the top, which drives the drill bit to break the rock.
The turntable drilling rig machine fits a turntable at the drilling platform. The center part of the turntable has square holes, the square drill pipe at the top passes through the square hole. the power drives the drilling pipe and the drill bit to rotate, and break the rock.
The underground power drilling rig machine uses the underground power drill pipe to drive the drill bit to break the rock. Drilling pipe does not turn when drilling, so the equipment wear is small, long service life, especially for directional drilling, divided into turbine drilling, screw drilling and electric drilling and other types.
