200 Water Well Drilling Rig Description
NL 200 pneumatic drilling rig is especially suitable for water intake in mountainous and rocky strata.Pneumatic water well drilling machine should be used together with air compressor, it can add mud pump and foam pump. Need to use different drilling tools such as: drill rod, hammer, rock drill bits, etc.Our drilling rig is equipped with high hydraulic outriggers. If you need this function, we can provide you with this configuration extra, because it can be convenient for you to install the drilling rig on a truck for long-distance transportation.

NL 200 Water Well Drilling Rig Advantages
It is hydraulically driven by diesel engine. The dashboard is simple and clear. It is a crawler mounted structure, which is easy to move. Steel crawler chassis is adopted (of course, you can also choose rubber crawler to facilitate walking on urban roads). Four standard high legs . When loading by car for a long transportation, you can directly get on the car without lifting. During operation, there are four hydraulic legs to adjust the angle and stability of the car body.
NL 200 Water Well Drilling Rig Applications

What aspects should we pay attention to in the drilling process of water well drilling rig?
1. After the drilling structure of the drill bit of the water well drilling rig is drilled, the central drilling tool needs to be replaced in time. First, the hole bottom needs to be cleaned, and then the residue at the hole bottom needs to be blown away. After the drill bit stops rotating, the drilling tool in the water well drilling rig can be lifted up slowly. When the lifting force is just enough to lift the drilling tool, it is the most appropriate.
2. During the drilling process, the drill bit of the water well drilling rig shall be summarized. It is also necessary to carefully observe the follow-up situation of the casing, timely understand the specific situation in the hole, and keep the hole clean when necessary. Moreover, the drill bit in the water well drilling rig shall not be pulled out by force during the drilling process.
3. Sometimes there will be more residual rock slag at the bottom of the hole of the water well drilling rig, and the rotating part of the eccentric bit will be stuck by the rock slag, which will affect its retraction and production. At this time, it is necessary to transport air pressure, clean the hole again, make the DTH hammer work in a short time, and then lift the central drilling tool again.
