Operation and maintenance Of Drilling Hammer:
1、Because the drive chuck and top sub of the Drilling Hammer are all right-handed threads, the Drilling Hammer should always be kept turning right during the drilling work.
2、Start collaring with reduced throttle to the impact mechanism and feeding, let the bit work its way slightly into the rock.
3、It is important that the feed force is adapted to the weight of the drill string. The force from the feed motor needs to be corrected during drilling, depending on the variable weight of the drill string.
4、The normal rotation speed for Drilling Hammer lies between 15—25rpm. The upper limit generally produces the best generation rate, however, in highly abrasive rock, rpm should be in order to avoid excessive wear of the drill bit.
5、Clogged or cave-in of the hole, can lead to a stuck drill. It is best therefore, to cleans the hole regular intervals, by carrying out air-blowing with the Drilling Hammer.
6、During the pipe connection process, rock ballast and various impurities will fall into the Drilling Hammer, so the loose threaded end of the drill pipe must be capped to ensure that the drill pipe does not stick to rock ballast and dust.
7、Reasonable lubrication of the Drilling Hammer can never be ignored, otherwise, it will accelerate the wear of the Drilling Hammer and even cause damage.
