Currently a large part of the construction of drilling rigs to pass through Quaternary soil, gravel layer and other complex formations 130 drilling machine manufacturers, pile-hole forming aspects, the impact of reverse circulation construction aperture is generally clay, loam, silt quality soil, when silt layer construction to prevent collapse hole, still using positive cycle percussive drilling, but easy necking, but the verticality of the pile is better, according to the data I had several engineering construction showed 130 drilling rigs In the mean filling coefficient rotary drill feed section 1.15; while the filling factor of the drilling machine into the segment was 1.25, the filling factor in the impact of soil and rotary base close to the above is some preparatory work for the drilling machine before operating For more information about 130 drilling machine manufacturer, I believe that through this article 130 drilling machine image, many people will prepare matters for drilling rigs operating before have more understanding, I believe that many people are It is very useful. Work drilling machine is pumping reverse circulation type. It works are: the role of atmospheric pressure, the circulating fluid from the settling tank through the return ditch along the annular gap flow to the wellbore bottom, because the turntable drive drill, drill drive rotation of drilling, established by the mud pump suction vacuum the debris drill mud suction lumen, then rose to the faucet, the mud pump into the sedimentation tank, circulating fluid continues to flow after precipitation wellbore, so again and again, forming a reverse circulation drilling work. Mud or water from the drill pipe into the outflow from the wellhead. Positive circulation drilling machine. Mud or water from the drill pipe sucked out from the wellhead inflows. For the reverse circulation drilling machine. Refers to reverse circulation drilling fluid (mud or water) in the drilling machine cycle ways to say, the drilling machine drill drilling time will have to produce sediment, slag stone, by reverse circulation can take the mud these scum to the ground, and then through the mud after the settler back to drilling. Thus, the continuous cycle, and finally into the hole. Reverse circulation can bring a larger diameter slag. 130 drilling machine image, irrigation County 130 drilling machine, Prius Prius provided by Luoyang Drilling Equipment Co., Ltd.
