Komponenten für erneuerbare Energien: Energieerzeugung mit Federkraft
Veröffentlicht: 2025 08 21
Rund 50 % der Stromerzeugung im Vereinigten Königreich stammen mittlerweile aus erneuerbaren Quellen wie Wind-, Wasser- und Solarenergie. Mit dem weiteren Wachstum dieser Sektoren steigen auch die Anforderungen an Langlebigkeit, Präzision und Zuverlässigkeit – speziell bei den essenziellen Bauteilen, die Energiesysteme am Laufen halten. Hier kommen Federn und ähnliche Komponenten ins Spiel – von Sonnenverfolgungssystemen über Bremsmechanismen für Windräder bis hin zu Wasserkraft-Durchflussregelungen und Energiespeicherlösungen spielen sie eine zentrale Rolle in der gesamten erneuerbaren Energiebranche.
Lesjöfors kombiniert fortschrittliche Federnfertigung mit Expertise in Gasfedern, Stanz- und Biegeteilen sowie individuell entwickelten Lösungen, um den anspruchsvollen Anforderungen der globalen erneuerbaren Energiewirtschaft gerecht zu werden.
In this post, we’ll explore how renewable energy components rely on Lesjöfors products, highlight key applications, and share examples of innovative projects shaping the future of energy generation.
Renewable Energy Equipment
Every renewable energy power plant, whether it’s solar, wind, hydro, or biomass, depends on precisely engineered parts to perform reliably in harsh and demanding environments. From compression springs to stamped components, there are many critical parts hidden within these systems, enabling safe operation, smooth movement, and stable energy conversion.
Solar Energy Components
Solar energy systems rely on photovoltaic panels, inverters, racking assemblies, and sun-tracking units. As part of wider renewable energy equipment, these components must operate continuously under exposure to heat, wind, and UV radiation.
Springs in Solar Energy Applications
Lesjöfors supplies a range of products that support solar energy systems. Torsion and extension springs feature in solar tracking mechanisms, helping panels follow the sun’s path for maximum efficiency. Gas springs are widely used for safe panel lifting and maintenance access, while pressings and stampings provide structural support in mounting assemblies.
Wind Turbine Components
Wind turbines require large-scale renewable energy equipment, including rotor blades, nacelles, and gearbox systems. These components must resist high mechanical stress and variable wind conditions.
Springs in Wind Turbine Applications
Lesjöfors springs are widely used in generator control systems and pressure relief mechanisms, ensuring safe, stable, and efficient turbine performance.
Large compression springs are vital in braking systems, while precision wire forms are used in sensors and electronic controls. Gas springs improve safety in service hatches, and pressings and stampings provide structural reliability within nacelles and blade assemblies. Pitch control systems rely on torsion springs to adjust blade angles, while vibration-damping springs protect sensitive components from constant motion, improving turbine efficiency and reducing downtime.
Hydroelectric Systems
Hydropower plants use dams, turbines, and flow control gates to convert water pressure into electricity. These renewable energy power plant components operate under constant hydraulic force.
Springs in Hydropower Applications
Our springs control hydraulic flow and mechanical movement in critical hydropower systems. We also provide heavy-duty coil springs for gate regulation and turbine assemblies, as well as corrosion-resistant pressings for structural housings.
Gas springs are widely used in maintenance and handling equipment, improving operator safety. Turbine and flow gate systems rely on compression and torsion springs to regulate movement with precision, while shock-absorbing springs protect machinery from pressure surges, extending service lifespan.
Renewable Energy Storage Systems
Energy storage balances supply and demand across renewable grids. Example applications include batteries and pumped hydro storage, each requiring durable, reliable components.
Springs in Energy Storage Applications
Lesjöfors products are integral here. Contact springs provide secure electrical connections in battery packs, while gas springs are used in cabinet systems for safe operation and maintenance. Pressings and stampings support enclosures and structural assemblies. Springs also accommodate thermal expansion in batteries, ensuring stable performance over repeated charge cycles. In mechanical storage systems, damping springs maintain rotational balance and absorb shocks.
Ocean Energy Components
Tidal and wave systems capture the motion of the sea through turbines, floats, and oscillating devices. These demand renewable energy components that resist corrosion, continuous motion, and constant impact.
Springs in Tidal & Wave Energy
Lesjöfors manufactures stainless steel and alloy springs for tidal turbines, mooring systems, and converters, alongside marine-grade pressings and gas springs designed for saltwater durability. Springs absorb motion and reduce stress in tidal and wave converters, protecting both the structure and the power output systems. Materials are carefully chosen for corrosion resistance in extreme marine conditions.
Biomass Energy Components
Biomass facilities generate power from organic matter through combustion, digestion, or gasification. Key equipment includes feedstock conveyors, combustion chambers, and turbines.
Springs in Biofuel Applications
Lesjöfors supplies heavy-duty springs for valve systems, gas springs for maintenance equipment, and pressings and stampings for feed handling systems. Fine wire springs are also used in monitoring sensors and control units. Springs regulate pressure and flow in combustion chambers, ensuring safe and efficient performance. They also support conveyor and feeder systems, maintaining consistent throughput in biomass plants.
