The drill bit plays an important role in the drilling process of Water Well Drilling Tools. The quality of a drill bit directly affects the efficiency of water well drilling and the quality of the hole, so we need to pay attention to the selection and use of the drill bit. During the drilling process, the operator should pay attention to the use of the drill bit to make the drill bit better for production operations. Several aspects of the drill bit in Water Well Drilling Tools:
1. After the drill bit of Water Well Drilling Tools is drilled into the structure, 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 is blown clean. After the drill stops rotating, the Water Well Drilling The drilling tool in Tools is slowly lifted upwards. It is most suitable when the lifting force is just enough to lift the drilling tool.
2. The drill bit of Water Well Drilling Tools is summarized in the drilling process. It is also necessary to carefully observe the follow-up situation of the casing, timely understand the specific situation in the hole, and keep the hole clean when necessary, and in Water Well Drilling Tools The drill bit must not be pulled out forcefully during the drilling process.
3. The bottom of the hole of Rock Button Bits sometimes leaves a lot of residual slag. The rotating part of the eccentric bit will be blocked by the slag, which will affect its gathering and production. At this time, it is necessary to deliver compressed air and re-execute the hole. Clean and make the down-the-hole hammer work for a short time, and then re-start the lifting operation of the center drill.
