Use submersible drilling rig Notes: 1, drilled three elements - that is, under certain conditions of pressure and borehole size, speed, torque, pressure shaft to be the best match, it is with a specific type of rock formations and changes change. 2, for metal ore mines finer particles, the greater the proportion of the more tenacious, drill more easy to wear. For example: When the grade of 50% or more, the life of the drill hole of 150mm less than 20 meters. 3, for the users of the old with the new rig submersible drilling rig, the operator before the appointment is subject to technical training. 4, the proposed Ken scum layer of soil into the hole is not easy, sand, gravel, gravel layer, breaking layer, layer of reinforced concrete drilling use. 5 drill holes inclined, horizontal hole, drill life reduced accordingly. 6, low pressure impactor should use ≤0.8Mpa; use high-pressure shock pressure should ≤2.5Mpa. 7, in case of technical problems not mentioned principles used submersible drilling rig for sale, please contact and consultation with the manufacturer. DTH drill ready before the start: The DTH drill conduct a comprehensive examination of each part (a) carriage ministries weld without cracking, without loosening the connecting screws submersible drilling rig for sale, each connecting rod tensioning device reliability.
