Any product needs to be operated in the right way. Spiral drill pipe is a kind of equipment that can be used in geological engineering and other construction projects. In the process of using this equipment, we need to understand the precautions for using the drill pipe. 1. The storage of the drilling rig shall be moisture-proof and ventilated. Do not strike gears and screws during operation. 2. It is strictly prohibited to use hand drill to avoid uneven force on the three palms of the drill bit and accelerate the damage of the drill bit. 3. In normal perforation operation, the main air channel of the air compressor will not have more serious air leakage, so as to ensure sufficient air flow and pressure and prolong the service life of the drilling rig. 4. When the drill bit is in the hole and the air compressor suddenly stops working, it floats
Any product needs to be operated in the right way.auger drill pipeIt is a kind of equipment that can be used in geological engineering and other construction projects. In the process of using this equipment, we need to understand the precautions for using the drill pipe.
1. The storage of the drilling rig shall be moisture-proof and ventilated. Do not strike gears and screws during operation.
2. It is strictly prohibited to use hand drill to avoid uneven force on the three palms of the drill bit and accelerate the damage of the drill bit.
3. In normal perforation operation, the main air channel of the air compressor will not have more serious air leakage, so as to ensure sufficient air flow and pressure and prolong the service life of the drilling rig.
4. When the drill bit is in the hole and the air compressor suddenly stops working, the scum can easily enter the drill bit. Therefore, it is strictly forbidden to rotate for a long time, causing bearing wear, repeated extrusion of scum (or drill bit accessories), and accelerated drill bit wear.
5. When the bit is in the well, it is strictly prohibited to reverse to prevent the bit from falling into the well.
6. When drilling a new drill bit, first run it at low axial pressure and low speed for 20-30 minutes, and then gradually increase to normal axial pressure.
7. When a new drill bit opens a new hole, carefully remove debris (crushing, metal scrap, etc.) around the hole. When rotating, it should be slowly close to the ground ventilation to protect the drill bit from impact, impact and damage.
8. The drill bit should be reasonably stored on the drill bit to prevent dust and other debris from entering the drill bit.
9. Before drilling, please check the appearance of each part of the drill bit, whether the end face of the threaded fastener of the spiral drill pipe is consistent with the manufacturer's serial number and certificate on the bit box, and whether there are sharp marks on the surface of the new tooth to prevent counterfeiting.
The perforating operation of the drilling rig must follow the matching principle of the three drilling elements (wind pressure, axial pressure and speed) and the recommend drilling parameters. Ruilong drilling tools can provide "geological drill pipe, spiral drill pipe, rib drill pipe, double-arm drill pipe", etc.
Daily usedrill pipeWhen working in different rock formations, different types of drill bits, axial pressure and speed should be selected according to the hardness and softness of the rock; when working in soft rock formations and replacing the intermediate drill bit, the back palm and the old drill bit should be strictly checked. Alloy on the cone. Whether the tooth falls off from the bottom of the hole; when the old position is left in the hole, the new position should be strictly prohibited from being in the original hole; when the rock or rock crack caused by the explosion, it should be prohibited to use. When working in fissures and goaf, the axial pressure and speed should be reduced to prevent tooth breakage.
