NL 180 Water Well Drilling Rig Features :
1.180m DTH Crawler Mounted Well Drilling Rig is compact, and its width is only 1.3m, suitable for narrow drilling condition,
2.Perfect Maneuverability with hydraulic control.
In order to fulfill various application cases, the main parameters of drill can be adjusted, such as rotation speed, torque, feeding pressure anti-feeding pressure, feeding speed, lifting speed.
3.Rotation, feeding, lifting by Top driven.Easier for rod changing, reducing rod changing time, better for follow – down drilling.
4. Multi-functional drillingMultiple drilling ways could be worked on this rig, such as DTH drilling, anti-air circulation drilling, anchor drilling, rotation drilling, and follow-down drilling, as well as core drilling.
5. Low operation cost,Down the hole drilling for rocks has the lowest drilling cost with highest level of working productivity.
6. Crawler chassis with long stroke jack cylinders,Long stroke jack cylinders are easy for truck self loading during transportation, and crawlers are of better mobility in mud working sites.
7.Adjustable feeding pressure to get the best feeding force at various drilling depths.

How can we do a good job in the maintenance of well drilling rig?
1. Pay attention to check whether the bolts and nuts of water and gas pipelines and various accessories of the drilling rig are firm at any time
2. . Always check the lubricating oil condition of the wind motor
3. . When the working face is immersed in water, a large-diameter drill head shall be used to insert the drill pipe when opening the hole, so that the drill pipe is 1-2 meters above the water surface to prevent mud and rock slag from falling into the hole
4. . The drilling rig is not allowed to reverse during drilling operation, so as to prevent the drill pipe from falling into the hole
5.. When the drilling rig stops working for a short time, a small amount of air pressure shall be given to prevent sediment from invading the interior of the percussion device of the drilling rig. If the drilling rig stops working for a long time, the percussion device shall be lifted 1-2m away from the hole bottom for fixation
