Working Principle
The Kaishan KS350 operates on a hydraulic top-head drive principle. A diesel engine powers the hydraulic system, which drives the rotary head to generate torque and rotation. The feed system applies pull-down force to the drill string, while compressed air or mud is circulated through the drill pipe to remove cuttings. For hard rock, a down-the-hole (DTH) hammer is used, where compressed air drives a piston to impact the bit while the rotary head rotates it. The crawler chassis allows the rig to move between holes. The operator controls rotation speed, feed rate, and air/mud flow from the centralized panel to match geological conditions. This combination enables efficient drilling of water wells and other boreholes with good hole quality and penetration rate.
