Basic Info.
Core Barrel drill operating procedures
1)Before running the core barrel, the flexibility of the mechanism must be checked at the orifice.
2)Bucket flaps must enter the hole when fully stretched.
3)The initial drilling can not be pressurized, and then gradually pressurized after the backdrilling is stable. At this time, the core barrel should not appear to skip(move up and down).
4)If countersinking or stuck drilling occurs during drilling, stop pressurizing and do not use reverse drilling
5)During the drilling, it was found that the slewing resistance suddenly increased. At this time, it can be preliminarily judged that the core has been broken, and it can be reversed 2 to 3 times, and the core barrel can be lifted.
6)During the drilling process, a sudden pressure loss is found, that is, there is no resistance when turning. You need to stop drilling immediately and check to prevent the rotating shaft from breaking.
