Drill bit has a pivotal role in the drilling process of water well drilling rig. The good or bad of a drill bit directly affects the efficiency of water well drilling and the quality of formed holes, etc. Therefore, we need to pay attention to the selection and use of drill bit. In the drilling process, the operator should pay attention to the drilling use of the drill bit, so that the drill bit can produce better operation. Several aspects of the drill bit in the water well drilling rig need to be noted.
1、After the drilling structure of the water well drilling rig, the center drilling tool needs to be replaced in time. First, the bottom of the hole needs to be cleaned, and then the residue at the bottom of the hole needs to be blown clean, and after the drill bit stops rotating, the drilling tool in the water well drilling rig should be slowly lifted upwards, and it is more appropriate when the size of the lifting force is just enough to lift the drilling tool.
2、Water well drilling rig bits in the drilling process summary, but also need to pay careful attention to observe the casing follow-up, timely understanding of the specific circumstances of the hole, when necessary to keep the hole clean, and water well drilling rig bits in the drilling process prohibit strong start and pull.
3、Sometimes there will be more residual slag at the bottom of the hole of the water well drilling rig, and the rotary part of the eccentric drill bit will be stuck by the slag and thus affect its closing production, then it is necessary to convey the pressure air, clean the hole again, and make the submerged hammer work for a short time, and then carry out the lifting operation of the central drilling tool again.
