350m Depth Water Well Drilling Rig 300mm Borehole Industrial Steel

The ST 350 Steel Water Well Drilling Rig is equipped with powerful hydraulic rock drills that offer high penetration rates, reliability, and excellent fuel economy. With a 350-meter drilling depth and customizable drilling hole diameter, it is designed for water wells, agricultural irrigation wells, geothermal wells, and various other well types. This rig is particularly suitable for mountain areas and rock stratum water sourcing projects.

The pneumatic DTH drilling rig primarily drills rock and must connect with an air compressor. It features fast drilling speed, achieving 20-40m per hour with high drilling efficiency. Powered by a 63kw engine, it includes 4 high hydraulic legs that can lift 1.6m height for easy truck loading. The air water well drilling rig machine uses rubber crawler tracks, with hydraulic pumps and valves from import brands.

Pneumatic water well borehole drilling rig tower height can be configured as 3 meters or 6 meters to suit various project requirements.

During the selection process, careful attention should be paid to the selection and use of the drill bit. When operating the drill bit, several critical aspects must be considered to ensure optimal production and operational efficiency.

• Regularly check whether the bolts and nuts of water and gas pipelines and various drilling rig accessories are secure
• Consistently monitor the lubricating oil condition of the wind motor
• When the working face is immersed in water, use a large-diameter drill head to insert the drill pipe, keeping the drill pipe 1-2 meters above the water surface to prevent mud and rock slag from falling into the hole
• The drilling rig must not reverse during drilling operation to prevent the drill pipe from falling into the hole
• When the drilling rig stops working for short periods, maintain minimal air pressure to prevent sediment from invading the percussion device interior. For long-term stoppage, lift the percussion device 1-2m away from the hole bottom and secure it properly
