Drill pipe in coal mine workers often use products, but its specific use and maintenance methods, many people are not clear, the following to give you a brief introduction!
1. Drill pipe shall be maintained regularly. The maintenance period shall be determined according to the operating environment and air humidity.
2, the use of drill pipe should be in the rated drilling distance of the drill, according to the technical parameters of drilling distance and drill type, the selection of matching drill pipe.
3. When the drill pipe is used with the drill bit, the drill bit should be larger than the diameter of the drill pipe in general, and the condition of the drill and drill pipe should be paid attention to at all times in the drilling process. In case of stuck drilling or locking, stop drilling immediately or drill slowly after drilling to ensure that the drill pipe does not bend and deform.
4, drill pipe in ventilation or water, drilling should be sure that the drill pipe is tightly connected. When the drill pipe has seals, such as O-ring seals, attention should be paid to the use of the seals. In case of damage, corrosion and other phenomena, the seals should be replaced in time. After drilling, do maintenance and cleaning work on the seals.
5, drill pipe drilling should be manually correctly connected to ensure a close fit, do not use the drill directly drilling, to prevent damage to the drill pipe.
6. If the bending degree of drill pipe exceeds the standard requirements after use or the thread is damaged, and the normal operation cannot be done, it should be scrapped or returned to the factory for repair in time.
7. According to the standard requirements, we should ensure that the drilling depth of drill pipe meets the relevant requirements of geological drilling to prevent the occurrence of falling off due to the drilling depth reaching the limit of the use of drill pipe.
8. When working in acid and alkali areas, attention should be paid to the corrosion of drill pipe. At the completion of drilling, the rod body surface should be cleaned with water in time to remove the corrosion layer.
9. Drill pipe should be stored in a dry place with more support at the bottom. Regular maintenance should be carried out on drill pipe during long-term storage.
10. Drill pipe shall not be used as a support platform for heavy tail stacking. Drill pipe shall not be placed under rubble, coal or piled randomly.
11, drill pipe maintenance after rust removal/dust cleaning should be buckled on the protective cap or packing and sealing to ensure that the drill pipe is often new.
