Main characteristics

1. Working oil pressure: 12-16MPa;

2. High-pressure bladder accumulator, which replaces the high-pressure air system for power station;

3. High level of hydraulic integration; excellent technical performance indexes, and; reliable operation;

4. Its volume and weight only reach 1/2-1/3 of that for conventional governor;

5. The hydroturbine unit needs not to be provided with a governor shaft. The hydraulic oscillating cylinder directly replaces the connecting rod to control the speed ring;

6. Operating power: GYT600/1000/1800/3000/5000/7500/10000/15000/20000/30000kg.m.
