Every year on November 22 and 23, when the sun reaches 240 degrees of the yellow longitude, it is light snow. "light snow" is the second half of November in the solar calendar and the second half of October in the lunar calendar. "Light snow" is a reflection of the weather phenomenon of the festival.
triangular drill pipeRegular maintenance should be carried out, especially in winter. Yikuang Xiaobian will explain the use and maintenance of triangular drill pipe in winter.
1, triangular drill pipe should be carried out regular maintenance, especially in winter, according to the use of the environment and air humidity to determine the maintenance cycle, regular anti-rust oil and dust treatment.
2. The use of triangular drill pipe shall be within the rated drilling distance of the drilling rig. According to the technical parameters of the drilling distance and the drilling rig model, the matching drill pipe shall be selected.
3, triangular drill pipe is made of high quality carbon alloy steel pipe and its matching joint friction welding, so it has good follow-up and high tensile strength, can adapt to the soft geology
and deep hole drilling in soft coal seams. When working in soft geology and soft coal seam or other special environment, it is necessary to determine the reasonable drilling depth according to the physical properties and parameters of the actual material of the drill pipe.
4. When the triangular drill pipe is used with the drill bit, the drill bit should be larger than the diameter of the drill pipe under normal circumstances, and the condition of the drill and the drill pipe should be paid attention to at all times during the drilling process. In case of sticking, locking, etc.
For example, the drill pipe should be stopped immediately or drilled slowly after returning to ensure that the drill pipe is not bent and deformed.
5. When the triangular drill pipe is ventilated or ventilated, the drill pipe shall be closely connected during drilling. When the drill pipe has seals, such as O-ring seals, attention should be paid to the use of the seals.
In case of corrosion, etc., the seals shall be replaced in time. After the drilling is completed, do maintenance and cleaning work on the seal.
6. When drilling, the triangular drill pipe shall be connected manually and correctly to ensure close cooperation. It is not possible to directly drill with the drilling rig to prevent damage to the drill pipe.
7. If the bending degree of the triangular drill pipe after use exceeds the standard requirements or the thread damage causes the normal operation to be impossible, it shall be scrapped or returned to the factory for repair in time.
8, according to the standard requirements, should ensure that the drilling depth of the drill pipe in line with the relevant requirements of geological drilling to prevent the drill pipe due to the drilling depth to reach the limit of the use of the drill pipe, the occurrence of falling off phenomenon.
9. When working in acid and alkali areas, attention should be paid to the corrosion of drill pipes. When drilling is completed, clean the surface of the rod body with clean water in time to remove the corrosion layer.
10, triangular drill pipe should be stored in a dry place, the bottom should be multi-point support, long-term storage to deal with the drill pipe regular maintenance.
11. The triangular drill pipe shall not be used as a supporting platform for heavy tail stacking, and the drill pipe shall not be randomly placed under gravel, coal pile or scattered pile.
12,triangular drill pipeAfter rust removal/dust cleaning, protective caps shall be buckled or packed and sealed to ensure that the triangular drill pipe is usually new.
