As we know, jiangsu traction type drill of torque is fixed, then drill rod torque value is how to made up of those factors? Small make up also learned after consulting the technology factors, which affect the drill rod torque value consists of the following ways, are now learning to sell: drill rod torque value of the rod body is mainly composed of drill pipe specifications, material and tool joint forms, and the change of the production process the performance of the different conclusion. The change value is because of the different materials and process, drilling depth of the drill pipe and drill pipe of torque is related, but not by the drill stem torque to determine the depth of drilling, should choose according to different geological conditions and suitable for engineering drawing type of drill pipe, drill bit type to determine the drilling depth. So since the output torque of the drill pipe and drill choose good, according to the geological condition choose corresponding pipe after, choose good matching of bit can construction. Of course these are all theoretical data, in the process of construction of concrete problems and concrete analysis.
Depend on when drilling engineering pull-type rotary movement of the broken rock drill hole. Mainly has big, small pot cone drill, positive and reverse circulation rotary disc drill, hydraulic power head type drill rig, DTH vibration of rotary drilling rig, etc. Simple only drilling device, rotary drilling rig rotary drilling rig has perfect structure of drilling device and circulating flushing device of two parts. Rotating disc water well drilling rig drilling tools including drill pipe and drill bit. Commonly used in the name of the drill pipe with 60, 73, 89 and 114 mm in diameter. Bit points with drilling bit and ring with drilling bit two kinds big. Large and small pot taper drill rotating cone used its cutting soil. According to the size of the drilling tool called cauldron and small pot cone, cone can be driven by human or power. Cut soil debris fell into the pot, to discharge on the ground, it has simple structure, low efficiency, can only be used for general soil or sandy pebble is not more than 10 cm in diam., content is less than 50% of the formation. Small pot cone hole diameter of 0.55 meters, the drilling depth of 80 ~ 100 meters; Large taper hole diameter of 1.1 meters, the drilling depth of 30 ~ 40 meters.
Water well drilling rig crawler consists of segments and track pin, etc. Shandong rig caterpillar pin up track link connect all the segments. With a hole at both ends of the segments, and active gear, central has induced tooth, crawler for adjustment. Water well drilling rig crawler is introduced: the water well drilling rig crawler consists of segments and track pin, etc. Caterpillar pin up track link connect all the segments. Segments at both ends of the hole, and active gear, central has induced tooth, crawler for adjustment, and oil rig can prevent falls off to drive treads, strengthen antiskid reinforcement in contact with the ground side) (hereinafter referred to as decorative pattern, in order to improve the robustness of the segments and the crawler and the ground adhesion. Water well drilling rig sites and sprocket, roller, driving wheel and track link, etc.
