Drilling rig components
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.
