Machine parts that are used for generating energy via hydropower are exposed to extreme environmental conditions: they have to withstand very high loads, be resistant to saltwater and UV radiation and continuously operate without failure. Downtime due to material wear and frequent maintenance measures can negatively affect the energy output. igus offers a large variety of customer-specific solutions that fulfil the requirements of these sources of renewable energy, and help improve the technology of the entire system. Whether wave power plants, hydropower turbines or screening plants - there are a lot of application areas for our plain and spherical bearings lead screws and energy guide systems in the hydro energy industry.
This year, we are launching a total of 168 innovations. Industry Manager Richard Won presents the top hydro energy news in three minutes. One example is the KCRM steel rod end with internal threads:
Specifically for adjusting the rotor blades of hydropower turbines
For use in point absorbers
Also suitable for underwater use
Complete system for the moving energy supply in screening plants
Higher efficiency for the energy generator specifically in point absorbers
Energy chain for wave energy converter
CorPower Ocean, a Swedish company, makes point absorbers that are light and compact and cope well with storms thanks to the innovative Wavespring Phase Control Technology. A cascade gearbox that drives a power generator converts the buoy's up-and-down movement into rotational movement. Energy supply within the buoy is secured by two vertically installed E4.1 series e-chains and chainflex servo, power and control cables.
Tocardo's developers were looking for a way to route cables safely from the turbine to the converter in the control cabinet and thus achieve the longest possible service life for the system. igus provided the perfect solution with series E/4 e-chains, which are corrosion-free, completely resistant to persistently damp environments, easy to install, and quick to open if a cable needs to be replaced.
The Volta wave energy converter made by PolyGen Ltd in Chesterfield is the world's first device for generating renewable energy from ocean waves and is made predominantly of plastic. For the flap axles, the developers were looking for bearings that could withstand the high mechanical loads and corrosive saltwater for as long as possible. They found the perfect solution at igus: iglidur flange bearings made of H370, a material developed specifically for wet environments.
