SP350(350M) Water Well Drilling Rig

SP350 water well drilling rig is widely applied in the hole drilling of water wells, geothermal wells and so on. It can operate under different complicated geological conditions, with a larger drilling diameter. The unique longhole axial compression control system can adjust the propulsion reasonably, reducing the steering resistance of deep well drilling. The two-stage telescopic carriage enables the use of a 6m drill pipe, greatly reducing the times of pipe extension. Besides, the overhead drive head comes with a large spindle diameter, making the drilling rig suitable for the drilling of mud, air and foam to satisfy the requirements of different geological conditions.

Key Parameters
Drilling Depth:350m
Drilling Diameter:140-325mm

Diesel Engine Power:92Kw


1. The water well drilling rig equips a 92 kW Yuchai turbocharged engine to provide powerful movement.
2. Patented composite arm provides a long stroke and the dual cylinder lifting device provides a large lifting power of 13T.
3. The main arm of this water well drilling rig is installed with a stopper to protect the cylinder.
4. Professional extractor base is extremely durable and offers strong bearing capacity. Its wide chain plate causes little damage to the road.
5. The design of parallel transmission with independent oil pump allows for sufficient power, reasonable distribution. The unique hydraulic system offers simple maintenance and low cost.
6. The hydraulic motor is equipped with a reducer to ensure durability and long service life.
7. Fast distribution valve allows for three-gear speed regulation and a rotary speed of 66-135 rpm, enabling the drilling of water and air.
8. Each hydraulic hose is covered with a soft management unit to enlarge its service life.
9. SP350 water well drilling rig is driven by a diesel engine and its walking, turning, propelling, lifting, leg and discharge rod are hydraulic controlled.
10. This crawler mounted geothermal drilling is convenient to move. Its rubber tracked base enables it to travel freely in the city and courtyards without damaging the ground.
11. Strong hydraulic leg can adjust the height of the rig quickly and stably for easy loading and transposition.
12. The water well drilling rig’s special wellhead provides a certain center for drilling, ensuring a vertical drilling and the position accuracy.
13. The mechanical positioning of the carriage and frame improves the stability of this water well drilling rig.
14. The pneumatic system comes with a customized lubricator to lubricate the drill hammer, so as to increase the service life of the hammer.
