Features of SNR200C water well drilling rig machine :
1. Full hydraulic control is convenient and flexible
The speed, torque, thrust axial pressure, reverse axial pressure, thrust speed and lifting speed of the drilling rig can be adjusted at any time to meet the requirements of different drilling conditions and different construction technologies.
2. Advantages of top drive rotary propulsion
It is convenient to take over and unload the drill pipe, shorten the auxiliary time, and is also conducive to follow-up drilling.
3. It can be used for multi-function drilling
All kinds of drilling techniques can be used on this kind of drilling machine, such as down the hole drilling, through air reverse circulation drilling, air lift reverse circulation drilling, cutting drilling, cone drilling, pipe following drilling, etc. The drilling machine can install mud pump, foam pump and generator according to the needs of users. The rig is also equipped with a variety of hoists to meet the different needs of customers.
4. High efficiency and low cost
Due to full hydraulic drive and top drive rotary propulsion, it is suitable for all kinds of drilling technology and drilling tools, with convenient and flexible control, fast drilling speed and short auxiliary time, so it has high operation efficiency. The down the hole hammer drilling technology is the main drilling technology of the drilling rig in the rock. The down the hole hammer drilling operation efficiency is high, and the single meter drilling cost is lower.
5. It can be equipped with high leg crawler chassis
The high outrigger is convenient for loading and transportation, and can be loaded directly without crane. Crawler walking is more suitable for muddy field movement.
6. The positive and negative axial pressure can be adjusted
The best impact efficiency of all kinds of impactors has its best matching axial pressure and speed. In the process of drilling, with the increasing number of drill pipes, the axial pressure on the impactor is also increasing. Therefore, in the construction, the positive and negative axial pressure valves can be adjusted to ensure that the impactor can obtain more matching axial pressure. At this time, the impact efficiency is higher.
7. Optional rig chassis
The rig can be mounted on crawler chassis, truck chassis or trailer chassis.
