Well drilling rig works by pumping reverse circulation type, in the role of atmospheric pressure, water well drilling rig circulating fluid through the return from the sedimentation tank ditch along the ring gap flow to the bottom of the borehole, the drill drive rotation of drilling, established by the mud pump suction vacuum the debris mud suction lumen Tai'an tunnel drill rig, circulating fluid after precipitation continue to flow into the well bore. Well drilling rig operations and maintenance are very convenient tunnel drilling rigs, spare parts and long service life, is relatively low production costs. Drill new structure, to mention lead, breakout unique tools to facilitate the demolition drill pipe connection and fast. _ Long lowest tunnel rig industry machinery (certified) _ Long tunnel rig provided by Shandong Machinery Co., Ltd.. Shandong Machinery Co., Ltd. Dragon (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.
