How to maintain the extension rod

1. The use of the auger pipe should be within the rated drilling distance of the drilling rig, and the matching drill pipe should be selected according to the technical parameters of the drilling distance and the model of the drilling rig.
2. When the extension rod is used together with the drill bit, the drill bit should be larger than the diameter of the drill pipe under normal circumstances, and the conditions of the drilling rig and the drill pipe should always be paid attention to during the drilling process. If there are phenomena such as sticking or locking, the drilling should be stopped immediately or drilled back slowly to ensure that the drill pipe is not bent and deformed.
3. When the extension rod is ventilated or watered, it should be determined that the drill pipe is tightly connected when drilling. When the drill pipe has seals, such as O-rings, pay attention to the use of the seals, and replace the seals in time when damage or corrosion occurs. After drilling is completed, maintenance and cleaning of the seals are performed.
4. The extension rod should be connected manually and correctly when drilling to ensure a tight fit. Do not use the drilling rig to drill directly to prevent damage to the drill rod. It should be ensured that the drilling depth of the high-efficiency auger pipe meets the relevant requirements of geological drilling to prevent the drill pipe from falling off due to the drilling depth reaching the limit of the use of the drill pipe.
5. If the curvature of the auger pipe exceeds the standard requirements or the thread is damaged after use, it should be scrapped or returned to the factory for repair in time.
6. When working in acid and alkali areas, attention should be paid to the corrosion effect on the drill pipe. When drilling is completed, the surface of the rod body should be cleaned with clean water in time to remove the corrosion layer.
7. The extension rod should be regularly maintained, the maintenance cycle should be determined according to the use environment and air humidity, and the anti-rust oiling and dust-proof treatment should be carried out regularly. After maintenance and rust removal/dust cleaning, the protective cap should be buckled or boxed and sealed to ensure that the drill pipe is always new.
