In fact, the drill bit plays a decisive role in the process of the water well drilling rig, and the quality of a drill bit directly affects the efficiency and pore quality of the water drilling rig, so we all need the selection and use of the drill bit, during the drilling process, the operation Everyone must pay attention to the use of the drill, so that the drill can work better, and everyone pays more attention to some aspects of the drill.
1. After the drill bit of the water well drilling rig is drilled into the structure, it is necessary to replace the center drilling tool in time. First, the bottom of the hole needs to be cleaned, and then the residue at the bottom of the hole is blown clean. After the drill bit stops rotating, the drill in the water well drilling rig is drilled. It is most suitable when the lifting force is lifted up slowly and the lifting force is just enough to lift the drill.
2. The drill bit of the water well drilling rig is summarized in the drilling process. It is also necessary to pay close attention to the follow-up condition of the casing, to know the specific conditions in the hole in time, to keep the hole clean in time, and to drill the drill bit in the water well drilling rig. Strong lifting is prohibited during the process.
3. At the bottom of the hole of the water well drilling rig, there will be more residual slag. The eccentric drill bit will be stuck by the slag and affect the gathering production. At this time, it is necessary to transport the compressed air and re-clean the hole. And make the down-the-hole hammer work for a short time, and then re-do the lifting work of the center drilling tool.
