SPJ-400 water well drilling rig
The features of SPJ-400 water well drilling rig
SPJ-400 water well 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.
