Maintenance of down-the-hole impactor and drill bit-beneficial mining technology.
The advantages of 1. down-the-hole impactor and drill bit in water well construction 1. High drilling efficiency, long drilling tool life, down-the-hole impactor rock drilling, the medium is air, there is no problem of recovery and treatment of flushing medium, and auxiliary time is reduced. 2. The use cost is low. The down-the-hole impactor requires small shaft pressure on the drilling rig, low speed, low torque, low natural power consumption, relatively thin drill pipe diameter, easy installation and disassembly, and long service life. 3, DTH impactor drilling, the hole wall is more complete, no other media pollution, basically can maintain the original formation structure and water permeability, reduce the well cleaning time, save the cost. 4, in strict

Yikuang Technology analyzes the reasons for the damage of the down-the-hole drill bit for you.
Air DTH hammer drilling is mainly based on high-frequency impact crushing, which can often reach more than 10 times the drilling speed of regular drilling mode, but it is easy to produce various accidents due to the influence of factors such as operation process and complex formation. Common accidents of air down-the-hole hammer drilling mainly include hammer head fracture, alloy tooth collapse, blockage, blocking, mud ring wrapping, stuck drilling, etc. The systematic technical measures formed for the following typical accidents are highly operable and have popularization value. 1. Hammer head fracture occurs at the upper end of the hammer head spline. The common causes of hammer head fracture are:(1) poor quality of the hammer head itself, stress set

1. features 1. The construction process is simple, operable and easy to organize and implement. Through site investigation, design the crossing line, connect the drill bit and pipeline, and the drilling rig is in place, then construction can begin. 2. It does not pollute the environment, does not affect traffic, has little damage to the ground, and can meet the requirements of high environmental protection for urban underground pipe network construction. 3, low cost, significant social and economic benefits, can reduce the administrative examination and approval of excavation, convenient construction organization, low comprehensive cost. 4, good safety, due to the use of pipe construction, construction personnel operations are carried out on the ground, to avoid the impact of deep foundation pit operations and other adverse construction conditions, improve the safety system.

The main body circular grooved drill pipe, rib drill pipe and special-shaped multi-edge grooved drill pipe all have cooling function, especially the latter has directional righting function (not easy to collapse holes, good hole forming quality), taking into account multiple slag discharge principles, and will become the main drilling tool for gas extraction deep hole drilling. Compared with the current coal mine gas drainage using smooth round drill pipe and ordinary triangular drill pipe, because the rod body has no groove structure, protruding coal seam, especially soft coal seam, should not use hydraulic slag drilling. Dry drilling lacks cooling function under blockage (cinder cannot move along the axial direction). Comprehensive comparison, special-shaped multi-edge grooved drill pipe, with hole protection, pressure relief, support

Quadruple Efficacy of Special-shaped Multi-edge Groove Drill Pipe ---- Yikuang Technology
The four functions of the special-shaped multi-edge grooved drill pipe are as follows: 1. The patented structure of the protective hole is rotated in the loose drilling slag to cause the axial vortex flow along the rod body to form a slag discharge airflow, and the drilling slag is discharged through the slag discharge channel formed by the spiral groove. When the drill pipe is buried by the loose drilling slag or the drilling hole collapses, the drilling slag can be discharged through the slag discharge channel. 2, quenched and tempered nitrided drill pipe to join the heat treatment process to strengthen the overall force performance, so that it has a strong hardness and good plasticity and toughness, the joint by nitriding treatment to further strengthen the anti-grinding, anti-fatigue, anti-corrosion and anti-high temperature characteristics. 3. The multi-edge structure of the cooling function rod body can reduce the contact area between the drill pipe and the hole wall,
