Drill rig composition structure we used classification roughly: rotary drilling rig, vibration drills, impact drills and complex rig. The main structure is made rig drilling rig itself, rigs, mud three major components. When the rig is used to lower and raise drill hole, the drill pipe to the lifting bracket by raising the wheel, reverse action, drill and drill steel 丝绳提 usefulness. Further drilling rig itself is again: clutch, drilling disc (folder drill), lifting wheel, hydraulic control systems, pump stations, body, faucets, spindle gearbox and other components. In operation, the drill pipe clamped on the drill plate, by the power (electric motor or diesel engine) driven rotary drill through the transmission system, and the most distal end of the drill bit mounted, feed force by the hydraulic system control, when drilling a certain depth, followed by a long drill, and so forth to drill until the holes drilled to the desired depth. When the drilling mud pump is to drill high-pressure pump cooling water supply, cooling demand due to the drill bit during drilling, while also discharging the drilled mud sand, so after the drill hole in the middle to high-pressure water transport to the drill bit while submersible drilling rig, together with high-pressure water and sediment from the drill hole is extruded around. So when you say that the effect of drilling mud pump is very important. Use submersible drilling rig in the technical points of DTH drilling industry rapid development, promotion and application in an increasing number of drilling projects, mainly because of its cost advantages. Now involved in the drill rod solder industry with increasing business. Submersible drilling rig in the use and maintenance are required attentive, so as to extend the life of the tool, play a greater effect. Drilling three elements - the drilling rig, speed, torque, axial compression shall be the best match under certain conditions of pressure and borehole size, which is included with specific rock formations and types of change varies. The following briefly about submersible drilling rig in the course of technical points: 1, with the new rig for users of small rig operator before the appointment is subject to technical training. 2, recommended that the soil is not easy to Ken scum hole, sand, gravel, gravel layer, breaking layer, reinforced concrete layer drilling use. 3, drilling inclined hole horizontal hole, drill life reduced accordingly. 4, low impact uses pressure should be ≤0.8Mpa; use high-pressure pneumatic shock should ≤2.5Mpa. 5, the metal mine ore finer particles, the greater the proportion of the more tough, drill more easy to wear. 6, in case other, more complex technical issues, please contact the manufacturer an advisory and consultative tunnel rig, Long industry machinery (online consultation), the rig by Dragon Machinery Co., Ltd. Shandong. Machinery Co., Ltd. Shandong Long (www.longyejixie.com) is Tai'an, engineering machinery parts leaders, over the years, the company implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Lung industry machinery leadership with the staff warmly welcome all inquiries negotiations to create the dragon industry machinery better future.
