China's mining machinery and equipment will face a new round of industrial demand, especially the demand for drill pipes, drill bits and other accessories is becoming more and more extensive. More and more mining has just begun to use mechanization to improve mining efficiency and eliminate hidden safety risks. The degree of mechanization of coal mines, copper mines, zinc mines and other mines has greatly increased the market capacity of mining machinery and equipment. Drill pipes and drill bits should be safe when used, which requires us to strictly follow the use steps. Strictly check before use. In order to measure the diameter of the drill bit, the connecting thread should meet API standards, no damage, perfect gears and seals, no interaction between gears, and no crack welding
China's mining machinery and equipment will face a new round of industrial demand, especiallydrill pipeThe demand for accessories such as drill bits is also becoming more and more extensive. More and more mining has just begun to use mechanization to improve mining efficiency and eliminate hidden safety risks. The degree of mechanization of coal mines, copper mines, zinc mines and other mines has greatly increased the market capacity of mining machinery and equipment.
Drill pipes and drill bits should be safe when used, which requires us to strictly follow the use steps. Strictly check before use. In order to measure the diameter of the drill bit, the connecting thread should meet API standards, no damage, perfect gears and seals, gears do not interact, no cracks are welded, air holes are welded, bearings are not loose, and nozzles are installed correctly and reliably. The inspection results and the number of drill bits should be clearly recorded, and the drill bits found to have problems cannot be carried out smoothly.
Special attention should also be paid to its installation. When installing the nozzle, the nozzle and the housing should be kept clean, the nozzle body should be smooth and undamaged, the sealing ring should be complete, the hammer is strictly prohibited, so that the nozzle and the sealing ring are not damaged, and the nozzle yellow must be reliable to avoid the nozzle. The drill bit should be equipped with a suitable loader. When using the drill box, the drill box should be filled with rope or rags to prevent damage to the teeth.
When drilling and drilling, special attention should be paidPDC BitsThis drill is more prone to errors. Before drilling, the index table and automatic recorder should be corrected. The drilling operation should be stable, and the descent speed should be controlled. Special care should be taken in hard formations, irregular well diameters and inclined well sections to avoid the drill bit hitting the well wall to cause tooth fracture or tip damage, resulting in early seal failure.
