Mechanical Seals
Mechanical seals are devices used to prevent the leakage of fluids between two surfaces in relative motion. In the context of space and astronautical engineering, mechanical seals are used in various applications such as rocket engines, pumps, and valves to prevent the leakage of fluids such as fuel, oxidizer, and hydraulic fluids. The performance of mechanical seals is critical for the safe and efficient operation of these systems. Factors such as temperature, pressure, and vibration can affect the performance of mechanical seals, and therefore, they need to be designed and tested to withstand extreme conditions. The design of mechanical seals involves selecting appropriate materials, such as ceramics and carbon, and optimizing the geometry of the seal to ensure a tight and reliable seal. Testing of mechanical seals involves various methods such as pressure testing, leak testing, and endurance testing.
