ST 300 Pneumatic Borewell Machine Main Parameter:

ST 300 Pneumatic Borewell Machine Advantages:

The rig can create drilling jobs in different strata, borehole diameter can up to 245-294mm. The rig with hydraulic technology,supporting high torque hydraulic motor rotation and large bore hydraulic cylinder push, the multi cylinder engine of famous factory provides power for the hydraulic system.

ST 300 Pneumatic Borewell Machine Operating Instructions:

During the working process of water well drilling rig, the pump is 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 through the return ditch along the annular gap of the well. At this time, the rotary table drives the drill pipe to drive 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 and discharges it into the sedimentation tank through the mud pump. The circulating fluid after sedimentation continues to flow into the well, The reverse circulation drilling work is formed.
