The main drilling method of the drilling rig is rotary table - mud
positive circulation drilling; If equipped with appropriate
drilling tools, it can also adapt to other drilling tools
It can be drilled in clay, sand layer, bedrock and other strata. At
the initial stage of opening, the pressure mechanism can be used to
pressurize the drilling tool to realize
Pressurized drilling is used to improve the efficiency of shallow
hole drilling. With the increase of hole depth, when the weight of
drilling tool exceeds the pressure that needs to be added to the
drilling tool, it can be implemented
Decompression drilling.
The drilling rig is equipped with a main winch, an auxiliary winch
and a tool winch. The main winch is used to lift drilling tools and
lower wells
Tube, etc. The auxiliary winch is used to drive the impact sampler
or other coring tools and sand lifting cylinder, and can also be
used for well washing operation. Tool winch
It is mainly used to lift and move a single vertical root, and can
also be used to lift other tools to reduce physical labor.
The load distribution of the front and rear axles of the whole
machine is reasonable, with good driving and off-road performance.
Each core component has enough space for operation and maintenance,
It can be safely and conveniently maintained by operators. The
whole machine has good wind and sand resistance and seismic
performance, and can adapt to - 20 ° C-45 ° C
Operate at ambient temperature.
The main power components and hydraulic components of the machine
are from regular and reliable manufacturers, and all oil seals and
bearings are standard parts.
