Explore key applications of metal seals in aerospace

As a key sealing component, metal seals play an important role in the aerospace field. This article will explore the key applications of metal seals in the aerospace field and their importance in improving flight safety and performance.

1. Engine Sealing System:

The sealing system of an aerospace engine is an important part of ensuring the normal operation of the engine and flight safety. Metal seals are widely used in various parts of the engine, such as high-pressure compressor seals and combustion chamber seals in turbojet engines. These seals need to have high temperature resistance, pressure resistance and good sealing performance to ensure efficient operation and safe flight of the engine.

2. Hydraulic System Seals:

Metal seals are also widely used in the hydraulic systems of aerospace vehicles, such as the seals of hydraulic pumps, hydraulic cylinders, valves and other components. These seals need to be able to withstand the challenges of high pressure and high temperature environments to ensure the stability and reliability of the hydraulic system to support the various missions and operations of spacecraft.

3. Door and porthole seals:

The door and porthole seals of aerospace vehicles are key components to ensure the safety of crew and passengers. Metal seals are widely used in the sealing systems of doors and portholes to prevent air pressure loss and the influence of the external environment. These seals need to have good pressure resistance and sealing performance to ensure flight safety and passenger comfort.

4. Fuel system seals:

Metal seals are also needed in the fuel system of aerospace vehicles, such as fuel pipes, fuel tanks, joints and other parts. These seals need to have good corrosion resistance and sealing performance to ensure the safe and reliable operation of the fuel system.

5. Summary:

Metal seals are of irreplaceable importance in the aerospace field. They play a key role in key parts such as engines, hydraulic systems, doors, fuel systems, etc. Through continuous technological innovation and quality control, the performance of metal seals will continue to improve, making greater contributions to the development and safety of the aerospace field.
