Abstract:
This disclosure describes embodiments of a system and device to prevent damage that can occur during an over-speed condition in a turbo-machine. The embodiment includes a fluid circuit with a header, which couples to the turbo-machine, and a hydraulic circuit through which fluid can evacuate the header to a drain. The hydraulic circuit includes a trip header manifold with a pilot element in flow connection with a drain valve element that has an actuator to regulate the flow of fluid from the header. In one example, the pilot element uses solenoid valves to change the pressure of a fluid in the drain valve element and, in particular, maintains the actuator in a first position to prevent fluid to evacuate during normal operating conditions at the turbo-machine. When the over-speed condition occurs the actuator moves to a second position to place the header in flow connection with the drain.
