GK 200 Portable Test Drilling Machine for Geological Exploration With 295mm Diameter
Product Description:
1. Compact structure of the whole machine with small dimensions meets the requirement of drilling in limited space and tunnel transportation.
2. With two optional drive modes of the drive unit, the drilling rig has a wide adaptability of strata.
3. Extendable mast (or optional box-type mast) is adopted to meet the requirement of long casing drilling construction, which improves the working efficiency.
4. Integrated visualized pressure feeding system can regulate the drilling pressure accurately according to the drilling depth.
5. With the configuration of 4 hydraulic supporting legs, it can realize rapid horizontal adjustment and transportation without crane.

Product Features
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.
Precautions for drilling and coring machine
1. When drilling, the drill shall have small hand resistance and smooth cutting. The feed speed during drilling shall be about 4-5m/min. When the drilling is nearly completed, the drilling will vibrate due to the change of cutting force. At this time, the feed speed shall be appropriately reduced. When the cutting is completed, the drill shall be quickly lifted until the cutting edge is separated from the work, and the drill shall be shut down and the water source shall be cut off. 2. Adequate water cooling must be maintained throughout the drilling process. 3. When quickly lifting the drill bit during and after drilling, do not stop, but stop the spindle rotation when the drill bit just disengages from work, and then lift the drill bit. 4. During drilling, if the drill bit is found stuck, the drill bit shall be quickly lifted for a section, and then slowly drilled in. Do not damage the drill bit by hard drilling.
