How to Maintain the Threaded Drill rod?

Threaded drill rod plays an important role in rock drilling and exploration engineering in today's society, but it also needs timely maintenance after use, otherwise it is easy to be damaged. Today, let's talk about how to maintain the threaded drill rods.

What are the maintenance methods of threaded drill rod?

1. The drill rod shall be maintained regularly, the maintenance cycle time shall be specified, and the rust and ash removal treatment shall be done on time.

2. The application of drill rod needs to select the matching drill rod according to the basic parameters, models and specifications of drill distance within the rated drill distance of the drilling machine.

3. During construction in hard rock layer, coal rock or other special natural environment, the drilling depth of the drill rod shall be determined according to the actual material physical performance index and main parameters of the drill rod.

4. When the drill rod and drill bit are used together, generally, the drill bit should exceed the radius of the drill rod. Pay attention to the situation of the drilling machine and drill rod at any time during the whole drilling process. In case of sudden sticking and sudden death, stop drilling immediately or drill in slowly after drilling back to ensure that the drill rod is not bent and deformed.

5. When the rock drill rod is in natural ventilation or water supply, it shall be clear that the drill rod is tightly connected when drilling. When the drill rod has sealing materials, such as O-ring, pay attention to the application of sealing materials. In case of sudden damage, corrosivity and other problems, the sealing material shall be replaced immediately. After successful drilling, clean and maintain the sealing materials.

6. When drilling the drill rod, it shall be manually operated and slightly tightened to ensure close cooperation (thread type). It is not allowed to drill directly with the drilling machine to avoid damage to the drill rod.

7. If the bending degree of the drill rod after application exceeds the standard requirements or the thread is damaged, resulting in the failure of the normal construction of the top hammer drilling rod, it shall be scrapped or returned to the factory for maintenance immediately.

8. According to the provisions of the standard, it should be ensured that the drilling depth of the drill rod meets the relevant regulations to avoid the problem of the drill rod falling off due to the drilling depth reaching the application limit of the rock drilling rod.

9. When working in acid-base areas, pay attention to the corrosive effect on the drill rod. Upon successful drilling, clean the surface layer of the rod body with clean water immediately to remove the corrosive layer.

10. The drill rod needs to be stored in a dry place with a little more support at the bottom. During long-term storage, the drill rod of the top hammer drilling tool should be cleaned and maintained on time.

11. The drill rod shall not be used as a support platform for the accumulation of heavy objects. The drill rod shall not be placed under the gravel and coal pile or stacked in a scattered manner.

12. After cleaning, maintenance and rust removal of the threaded drill rod, it is necessary to fasten the protective cap or put it in a cabinet for storage to ensure that the drill rod is always new.
