SPJ-400 water well drilling rig mill drill machin
1.The features of SPJ-400 water well drilling rig SPJ-400 disc drilling rig is powered by diesel engine, and can also be driven by motor in electric power area. The drilling rig is a bulk rotary table drill, which is mainly used for middle Quaternary, fine grained strata and soft rock layers. The main usageis: the hydrogeological conditions at the bottom of the exploration and survey; the drilling and drilling for the agricultural irrigation, the industrial water use, the underground tunnel ventilation, the bridge and other engineering drilling. When drilling rig works, mud flushing fluid (positive circulation) and rotary table are used to drive the drilling tools to rotate. Use winch system to realized ecompression drilling, lifting drilling,down pipe, impact sampling, vertical drilling tower. 2.The specifications of SPJ-400 water well drilling machine Borehole diameter 500mm-1800mm Drilling depth 400m Maximum output torque 18kn.m Active drill rod 108*108*12mm Drilling pipe 89mm Main indlass lifting power 30kn Assistant windlass lifting power 20kn Rotary table latusrectum 500mm Rotating speed (forward and inversion) 40/70/128r/min height of the drilling tower 13m Gross weight (excluding drill pipe) 9t External dimension 2200*6000*13000mm Drilling tower type A / hydraulic drilling tower This product is widely used inwaterconservancyproject, pile foundation engineering, bridge construction and so on.
