Key Features
- Automatic telescopic rig supported by two high-strength oil cylinders with hydraulic valve control for safe, efficient operation
- Rubber crawler chassis reduces weight, noise, vibration, and fuel consumption while being road-friendly
- Hydraulic high outriggers for rig leveling, truck loading/unloading, and auxiliary support
- 24V electric start diesel engine reduces operator fatigue, especially in cold conditions
- Includes BW-160 mud pump with large flow/pressure and easy maintenance
- Optional hydraulic pipe screwing machine (75-168mm) available to boost efficiency
Operation Principle
The water well drilling rig operates using reverse circulation. The pump circulates fluid from the sedimentation tank to the well bottom through the annular gap. The rotary table drives the drill pipe and bit for drilling while the mud pump's suction creates negative pressure to remove debris through the drill pipe's inner cavity, completing the reverse circulation process.
