There are several things you need to pay attention to the well drilling rigs while drilling a water well.
The drilling bit plays a pivotal role in the drilling process, Drilling bit affects the efficiency of drilling a water well and the quality of holes. So we need to choose and use of drilling bit carefully. In the drilling process, the operator should pay attention to the drilling bits, so that the drill bit can perform better. There are several aspects to be noticed for drilling bits of well drilling rigs:
The types of Crawler water well drilling rig we have here.
1. The drilling bits of well drilling rig drill through the ground surface structure, the drilling bit needs to be replaced by middle hole drilling bits, first, clean the bottom of the hole, and then blow the residue out of the water well. When the drill bit stops rotating, then lift the drill bit of the well drilling rig slowly upward. The lifting force of well drilling rig is just able to lift the drill bit is the most appropriate.
