Product Description
ST300 Pneumatic Water Borewell Machine With Yuchai Diesel Engine Underground Drilling
The ST300 Pneumatic Water Borewell Machine combines air DTH hammer drilling with water drilling capabilities, making it suitable for all types of geological conditions including soil layers, hard rock, gravel, and pebble layers.
Product Overview
The ST300 Pneumatic Drilling Rig Machine addresses the challenges of difficult drilling in soil layers with air DTH hammer and low construction efficiency of water drilling mud in hard rock, gravel, and pebble layers. This water-gas dual-purpose drilling rig is engineered for high core drilling efficiency in both drilling operations and geological exploration applications.

Key Features
  • Speed range of 14-1030r/min with maximum output torque of 9500N.m
  • Long travel speed doubling mechanism and mechanical power head with 3500mm stroke
  • Enhanced drilling efficiency with reduced drilling plugging and burning accidents
  • Mechanical operation with reserved functional interfaces for hydraulic system expansion
  • Customizable according to different user process requirements
Operation Guidelines
During operation, the pump is utilized for reverse circulation. Under 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. The rotary table drives the drill pipe to rotate the drill bit for drilling, while the mud pump's suction creates negative pressure to draw debris mud into the drill pipe's inner cavity and discharge it into the sedimentation tank.
Leakage Prevention
High water head conditions can cause mud leakage into the hole wall. Prevention methods include:
  • Strengthening the retaining wall with thick mud or clay filling for slow deformation
  • Repeatedly impacting the retaining wall with filled soil to infiltrate gravel and pebbles
  • Sealing joint leaks with absorbent cotton and quick-drying cement
