The GY300 water well drilling rig have the Character :
1. Adopt automatic hydraulic feeding equipment,improve the drilling efficient
2. Can replace the drilling rod without stop
3. Centralized handles, easy operation, safe and reliable.
4. The drilling rig, pump and diesel engine are installed on a common base frame to make sure the compact structure and save space
5. The weight is light with high detachability ,easy transportation suit for the operate in plains and mountain areas
The drilling rig has the following characteristics:
1. The drilling rig has many (8 gears) rotational speed stages and reasonable rotational speed range.
2. Low rotation speed, high torque, wide application range, can be used for high-speed drilling and low-speed large hole drilling radial drilling.
3. With two reverse speeds, the labor intensity is not high when handling accidents in the hole, and it is safe in the day.
4. The installed power of the drilling rig is large, and it can be equipped with diesel engine or motor.
5. The drilling rig is advanced in structure, reasonable in layout, flexible and reliable in operation, and easy to maintain, maintain and repair.
6. The drill has small volume, light weight and good detach-ability.
7. The vertical shaft of the drilling rig has a feeding distance of 600mm, which is conducive to improving drilling efficiency and reducing accidents such as sticking happen.
8. Stable moving, simple and reliable fixing, good stability of high-speed drilling, and large distance of hole opening.
9. The WOB meter is of oil filled shockproof structure, with simple scale, accurate indication and long service life.
10. The chuck of the drilling rig is of hydraulic pin type, which is reliably clamped and does not damage the active drill pipe.
