Rotating rig operation procedures

1. Check the height of the oil surface of each running assembly before the drill.

2. Check all connection bolts and tight threads, and find loosening and tightening in time.

3. Check whether each component has oil leakage, water leakage, and air leakage.

4. Add calcium lubricants to each lubricant on time.

5. Each class should be placed in the water of the drilling fuel tank.

6. When the drill is opened, the air should be given first, and then the drill should be raised slightly. During the drilling process, the force value of the rolling machine should be determined according to the size of the drill and the geological condition, and the drill head should be suspended. When the slag is interrupted, the drill head should be raised immediately, and the residue discharge will be slowed down slowly. When you stop your drill, you should first lift the drill, and then stop the wind.

7. Before the drill assembly is running, be sure to open the oil pump motor to make the system be in a good lubrication.

8. Cover the hole with a wooden board with a wooden plate. The tools and iron parts are strictly forbidden to fall into the hole.

9. During the drilling process, if the pointer of the current watch is swinging sharply and when the instantaneous current exceeds the tolerance value, it cannot be automatically disconnected, and the drill should be stopped first.

10. Drilling and drilling in the sand layer to apply low speed
