When the threaded connection of the drill rod is difficult to loosen, it will be moved to the threaded place for a while. Explain that the following points should be paid attention to during the use of drilling tools: Before entering the rod, adjust the appropriate impact pressure, propulsion pressure, rotation speed, and buffer pressure according to different geological rock formations, and adjust each pressure value to make the pressure value custom auger bits less than
The geological rock formations and rock hardness match each other. In the process of retreating the rod, try to avoid repeated vibration of the rod (this operation is one of the reasons for the large damage to the drill rod). We will give professional technical answers. After the drill rod is drilled, each drill rod that is withdrawn should be coated with cooling lubricant in the threaded end and quick interface of the drill rod-after the rock drilling operation is completed, the threaded joint of the drill rod is hot And there are some crushed stones and mineral water, and the cooling oil is applied to lubricate, reduce temperature, prevent corrosion and improve the wear resistance of the thread. at any time.
When drilling holes, make the drill tool group concentric to avoid bending and deformation of the drill tail, drill rod, and drill bit.Drill tool manufacturers talk about the precautions for use. The above precautions in the use process are mentioned here
