Product Description

DEFY DFQ-200 DTH Hammer Drilling Machine for Water Used

I. General Description
DFQ-200 water drilling machine is fully-hydraulic, air-operated drilling machine with lightweight, high efficiency and multi-functions.

II. Application
It is widely used for water well drilling, geothermal air-conditioning project and other boreholes, especially applicable to mountain area and rock formation water engineering.
Especially solve the problems to drill very hard rocks.

IV. Advantages
1. It can work on different geological stratum. Drilling Depth is up to 200m, caliber Φ 105-203mm.
2. It adopts new type full-hydro technology, with two big torque hydraulic motor. Rotary torque is up to 1050N. M, speed can be 135 rpm. Ten times more than traditional drilling rig.
3. Two large high pressure cylinders offer 8.5ton lifting force, ensuring the stable propelling force and lifting force.
4. Multi-cylinder water cooling engine offer rich power for hydraulic system, ensuring high efficient working.
5. The advanced new embedded guide wheel mechanism increases the carriage stroke(it can lift up to 4 meters drill pipe), which greatly facilitates users to unload drill pipe and casing.
6. Hydraulic control panel is easy to operate.
7. Crawler mounted mobile base can work in different stratum. High speed and protect the road.
