Full Hydraulic 350m Pneumatic Water Well Drilling Rig
Introduction of pneumatic drilling rig
Water and air drilling rig is an efficient and multifunctional drilling equipment. It is mainly suitable for drilling water wells,
agricultural irrigation wells, geothermal air conditioning holes and other wells, especially suitable for water intake projects in mountainous areas and rock formations. . The efficiency is ten times higher than that of traditional rotary drilling rigs, and the economic benefits created for users are extremely considerable. In particular, it solves the difficulty in drilling the soil layer with air DTH hammer, and the construction problem of the rotary drilling rig in the hard rock layer, gravel and pebble layer. It can work efficiently under various geological structures and realize the perfect combination of water drilling and air drilling.

Characteristics of pneumatic drilling rig
1. The drilling rig hydraulic transmission of the rig effectively utilizes the power. This makes the overall power loss small and the drilling cost low.
2. The drill rig has more positive speed stages and 14-500r / min speed range, and the output torque is 13428-250N.m.
3. The drilling rig has 2 reverse speeds, which is convenient for handling accidents.
4. The air compressor drilling rig adopts a long-stroke double-speed mechanism, a mechanical power head, and a power head stroke of 3400MM to improve drilling efficiency and reduce the occurrence of plugging and burning accidents.
5. The water well drilling rig rig uses dual oil pumps for oil supply. A single pump is used for drilling, and a double pump is used for confluence when lifting. The power loss is small and the auxiliary time is short.
6. The drilling rig machine has advanced structure and reasonable layout, which is convenient for maintenance, maintenance and repair.
7. The crawler water drilling rig machine chassis is adopted, and the trip of the outrigger
cylinder can be automatically loaded for 1.5m, which is convenient for relocation and transportation.
8. The drill rig reserves some functional interfaces in the hydraulic system, and can expand the functions according to the technological requirements of different users.
