Reliable Rotary Transmission
Solutions for Hydroelectric Power
In hydroelectric power generation, the ability to adjust turbine blade angles for optimal flow conditions is crucial. Penlink’s rotary unions provide supply and return hydraulic power to blade actuators, enabling precise adjustments to the turbine blades in varying water levels.
Our rotary unions are engineered for hydropower environments, designed to offer continuous and reliable operation. When integrated with electrical slip rings and positioning sensors, they ensure precise position feedback in addition to fluid transfer, allowing for the smooth and efficient functioning of hydropower turbines.
