1.The features of SPJ-300 water well drilling rig
·SPJ-300 water well drilling rig is powered by electric motors.
·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 usage is: the hydraulic geological conditions at the bottom of the exploration and survey; 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 realize decompression drilling, lifting drilling, down pipe , impact sampling, vertical drilling tower,etc..
·The drilling rig is equipped with fine adjustment drilling mechanism and mechanical screwing down drilling tool device
