What is the function of the sump vent subsystem components?

The function of the sump vent subsystem components is primarily to remove air that enters the oil through the oil seals. When oil is circulated within the system, it can create a vacuum effect that draws air into the oil sump. If not managed, this can lead to aeration of the oil, which adversely affects lubrication properties and can lead to a reduction in system efficiency or even damage to components.

By venting the air from the oil, the sump vent subsystem ensures that the oil remains free of air bubbles, maintaining optimal lubrication performance and extending the life of the gas turbine system. This is crucial because air in oil can cause issues such as cavitation and foaming, which can compromise the reliability and effectiveness of the lubrication system.

While other functions might seem relevant, they do not directly relate to the removal of air from the oil sump. For instance, regulating oil temperature is essential for overall system performance but is managed through different subsystems. Similarly, expelling excess oil during operation and filtering contaminants are important functions, but they do not address the specific role of the sump vent subsystem in aeration prevention.
