DFN-800 Fully Hydraulic Portable Drilling Rig
The drilling rig is a multi-purpose portable all-hydraulic engineering geological exploration rig, which is a rope coring rig with turbine diesel engine as power and adopts full-hydraulic power head drilling mode.
Product advantages
1. Adaptability: The maximum drilling depth can reach 800m, with drilling, sampling, comprehensive logging, hydrological test and other functions;
2, lightweight: the use of mast-type drill frame, modular lightweight design, easy to disassemble, handling, the most heavy module 180Kg, four people can carry;
3. Fast: The drilling rig can be driven at high speed and has high drilling efficiency. The thin-walled diamond rope is used for core drilling, and it has high performance in hard rocking layers such as hard rock, granite and quartz sandstone.
4, high exploration quality: the use of thin-walled drilling tools with full hole and pipe drilling, the core diameter is large, the disturbance is small, the adoption rate is more than 95%;
5. Safety enhancement: Full hydraulic transmission, the system has pressure limiting protection, effectively avoiding mechanical accidents and other safety accidents; no rig design, avoiding the risk of working at height; using straight-connected drill pipe, full hole with pipe drilling, right Generally, the fractured formation has good adaptability, and it is not easy to cause accidents such as boring holes to ensure the safety inside the hole.
6. Cost saving: The integration efficiency is more than 3 times higher than that of the traditional vertical axis drilling machine. It does not need road repair, no basic engineering, less floor space, and can be manually handled; it can save a lot of road repair and young crop compensation costs; easy operation and labor saving.
