Crawler Hydraulic Wells Geothermal Drilling Rig for Geothermal Projects Drilling
Crawler Hydraulic Wells Geothermal Drilling Rig
Crawler Hydraulic Wells Geothermal Drilling Rig
Roschen RS-W series drilling rig is an versatile internal combustion driven crawler hydraulic drilling rig that is designed and manufactured elaborately by Roschen Group Limited to ensure the stability of the rig's performance, the key components are imported.
The maximum drilling depth of the rig is up to 500 meters and drilling range is between 105-350mm in diameter. The rig can meet needs under the different geological environmental for geothermal projects, the exploitation of groundwater , hydro-geological exploration, pile construction and some other projects’ needs.
The whole rig is advantageous with a more powerful engine, bigger output torque, higher working efficiency and flexibility, as well as better stability and multifunctions, etc. When DTH hammer is applied on rock drilling in the operation, the crushed gravel is discharged by high pressure air-flows, and the drilling efficiency is ten times faster than the traditional rotary drilling rigs. Cutting drilling or cone drilling can be operated in the unconsolidated layer, rock and mud discharging. Totally, the rig is suitable for drilling in complicated geological conditions. Comparing with other competitors, the rig can replace the same type of the imported rigs and the performance price efficiency is more outstanding than the later.
Advantages:
Operation Panet:
The Control board is consist of console frame, electro-hydraulic valve, reducing valve, compensated flow control valve, oil pressure gauge, engine instruments, cable accelerator, ignition locks and other components. All control functions are centralized in the control tables, that makes operation easier and improve work efficiency.
Winch system
Hydraulic motor powered winch can flexibly hoist less than four point two tons of drilling tools or accessories.
Engine
Power system is diesel drive system. Cummins 93 k industry specific engine, hydraulic pump and motor provide a strong impetus for the rigs.
Generator
The drilling rig is driven by the hydraulic motor. A three phase synchronous ac generator with a output power of24 kw can be used as an emergency power supply, which is suitable for sleeve welding, or any other equipment that requires 380 V ac power supply.
Air filter
Two stage air filter can filter over 90% of dusts in the air inflow, which can effectively reduce the abrasion of engine, endare the lifetime and be used in various severe working conditions.
Wrench hydraulic cylinder
Hydraulic cylinder powered wrench can disassemble all kinds of joints quickly and lighten labor intensity.
Rotary Head
Rotary power head mounted on the drill, a rotary electro-hydraulic valve controls two hydraulic motors, enabling rotation speed and the two kinds of gearbox output torque to enable rig adapt to different working conditions.
Hydraulic Outrigger
Large stroke hydraulic legs for rig transport makes loading and unloading without lifting equipment, equipment can be self-loaded, hydraulic legs with the direction of the horizontal instrument to achieve rapid leveling rig.
Hoist & feeding system
Drilling and lifting are supported by hydro-cylinder - chain plate structure, which is safe, reliable and durable.
