SW-280J drilling rig is a mechanical top-drive drilling equipment that integrates water drilling and air drilling. It solves the difficulty of drilling with air drills and down-the-hole hammers in soil layers, and the low construction efficiency of water drilling and mud drilling in hard rock layers, gravel, and pebble layers. It is a water-air dual-purpose drilling rig that is suitable for various formations and has high efficiency in drilling cores for geological exploration and in drilling water wells. It is widely used in drilling water wells, geothermal wells, engineering holes, geological exploration, mineral exploration, etc. It is suitable for various construction techniques: air down-the-hole hammer drilling, mud drilling, single-tube coring, double-tube rope coring, etc.
Main feature:
1. The drilling rig speed can reach a speed range of 14-1030r/min, and the maximum output torque is 9000N.m.
2. The drilling rig adopts a long-stroke double-speed mechanism and a mechanical power head with a stroke of 2500MM to improve drilling efficiency and reduce drilling costs.
3. The drilling rig adopts dual oil pumps to supply oil. A single pump is used when drilling, and the two pumps are combined when lifting the drill. The power loss is small and the auxiliary time is short.
4. It adopts crawler chassis and the outrigger cylinder stroke is 1.5m, which can be loaded automatically, making it easy to relocate and transport.
