Woodward 8520-312
Product Overview
It is a pure mechanical hydraulic integrated governor designed for large bore diesel engine and steam turbine units. It relies on engine lubricating oil as power source, without external power supply, automatically senses speed change and adjusts fuel rack displacement. The overall structure is compact and integrated, with mechanical linkage and hydraulic amplification mechanism, adapting to high temperature vibration and oil mist harsh working conditions, and maintaining long-term speed regulation stability.
