    What should we pay attention to when operating the water well drilling rig?

    Water well drilling rig plays a very important role in the drilling rig. The drill bit is an important part of the drilling rig, which directly affects the efficiency of the water well drilling rig and the quality of the drilling rig after drilling. Therefore, we must pay attention to the drill bit when selecting the drilling rig.

    1. After the drilling structure of the drill bit of the water well drill is drilled, the central drilling tool needs to be replaced in time. First, the hole bottom needs to be cleaned, and then the residue at the hole bottom needs to be blown away. After the drill bit stops rotating, the drilling tool in the water well drill is slowly lifted up. When the lifting force is just enough to lift the drilling tool, it is the most appropriate.

    2. During the drilling process, the drill bits of the water well drilling rig should also pay close attention to the follow-up of the casing, understand the specific situation in the hole in time, and keep the hole clean when necessary. Moreover, the drill bits in the water well drilling rig should not be pulled up strongly during the drilling process.

    3. Sometimes there will be a lot of residual rock debris at the bottom of the hole of the water well drilling rig, and the rotating part of the eccentric bit will be stuck by the rock debris, which will affect its retraction and production. At this time, it is necessary to transmit air pressure, clean the hole again, and make the DTH hammer work in a short time, and then restart the lifting operation of the central drilling tool.
