1.The main charateristic of SPJ-300 water well drilling rig 

a.SPJ-300 disc drilling rig is powered by diesel engine, and can also be driven by motor in electric power area.

b.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 uses are: 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.

c. When drilling rigs, mud flushing fluid (positive circulation) and rotary table are used to drive the drilling tools to rotate. Winch system decompression drilling, lifting drilling, underground pipe, impact sampling, stand rig etc..

d.The drilling rig is equipped with fine adjustment drilling mechanism and mechanical screwing down drilling tool device.
