Hydropower and wind power systems operate under long-term continuous load and environmental exposure. Turbine assemblies, hydraulic pitch systems, braking systems, control actuators, and shaft sealing systems require sealing components capable of maintaining performance over extended service intervals.
Unlike intermittent industrial equipment, renewable energy systems are designed for sustained operation with limited maintenance access. Equipment may operate for decades under outdoor or offshore conditions, including moisture, UV exposure, ozone, seawater contamination, vibration, and abrasive particles. Sealing reliability directly impacts equipment uptime, operational efficiency, and lifecycle cost.
Seals used in hydropower and wind energy equipment are exposed to several demanding conditions:
These conditions require materials and seal geometries capable of maintaining structural stability, wear resistance, and sealing performance over extended service cycles.
