What defines Leakage in terms of gas turbine maintenance?

In the context of gas turbine maintenance, leakage is typically defined by the number of drops of fluid that escape from a system over a specified period, which helps in diagnosing the condition and integrity of various components such as seals and gaskets. A range of 6-10 drops in 5 minutes is considered acceptable and indicates a minor leak that can be monitored for future maintenance.

Defining leakage in this way allows technicians to categorize the severity of a leak and determine if further action is necessary. It's important to establish these thresholds to ensure that any leakage does not compromise performance or safety. In practice, if the rate of leakage exceeds this range, it could indicate a more serious issue that may require immediate attention, while lower frequencies may be deemed as normal wear and tear. Understanding these definitions helps in maintaining the reliability and efficiency of gas turbine systems.
