Aiming at the “high plasticity and strongswelling-shrinkage” characteristics of expansive soils, water well drilling rig selection should follow the “three highs and one strength” principle:
High torque output: Hydraulic system torque ≥ 3000N・m to cope with the viscous resistance of expansive soils.
High-speed adjustment: Bit speed continuously adjustable from 0-300r/min to adapt to formations with different water contents.
High-protection design: Electrical system with IP65 protection level to prevent clay particles from intruding.
Strong slag discharge capacity: Mud pump displacement ≥ 180L/min to ensure timely discharge of cuttings.water well drilling rig
