Hydraulics for drilling rigs

Efficiency and precision in use

Hydraulic systems are indispensable in drilling technology, as they provide the necessary power and precision to work efficiently even under extreme conditions. Drilling rigs enable the lifting, lowering, turning and moving heavy components – be it for oil and gas extraction, tunnel construction, geothermal projects or exploratory drilling. Thanks to their performance, they help to ensure that drilling projects can be carried out safely and efficiently.

Areas of application in drilling

Geothermal energy

Hydraulic systems play a crucial role in geothermal projects. They enable the precise control of drill rods and drill heads, necessary for the development of geothermal energy sources. Hydraulic pumps and cylinders provide the power required to successfully drill the deep boreholes under difficult geological conditions.

In addition to tapping deep geothermal energy sources, geothermal energy can also be used to drill hot water wells for the operation of heat pump systems.

Exploratory drilling and soil exploration

Precise and powerful hydraulic systems are essential when carrying out exploratory drilling and soil exploration. These drillings are carried out to analyze the nature of the subsurface, whether for the construction of large infrastructures or the preparation of mining projects. Hydraulic motors and cylinders are key components for moving drill rods precisely and achieving the required drilling depth.

Oil and gas production

In the oil and gas industry, hydraulics are used for onshore and offshore drilling rigs, mobile drilling rigs and horizontal and vertical drilling rigs to move drill pipes and precisely control the drill head. Hydraulic systems in this industry must withstand extreme pressures and temperatures to ensure that drilling operations are successful and safe.

Tunnel der sich noch in der Konstruktion befindet

Tunnel construction

In tunneling hydraulic systems are used for control of tunnel boring machines. These machines must work with high precision to enable tunnel driving under controlled conditions. Hydraulic pumps and cylinders play a central role in moving the drill heads and controlling the advance.

Hydraulic components in drilling rigs

Hydraulic Pumps

Axial piston, radial piston and gear wheel pumps provide the necessary pressure to guide the hydraulic fluid through the system and operate the drilling components.

Hydraulic Motors

These motors convert hydraulic energy into a rotating movement and are used to control the drill head and other rotating parts.

Hydraulic Cylinders

Hydraulic cylinders are used to lift, lower and position the drilling rigs, but above all for the drilling pressure. They convert hydraulic energy into mechanical movement, which is essential for the operation of drilling rigs.

Hydraulic Valves

Control valves regulate the flow of hydraulic fluid in the drilling rigs and thus enable precise movements of the drilling equipment.
