What is a true high-temperature seal? In specific applications, the performance range of standard seal structures can be improved by either cooling the sealed liquid and holding it at an appropriate operating temperature, or cooling the gland or seal to maintain an acceptable measurement of that part. Especially suitable for mechanical shaft seals, the seal structure often allows the use or substitution of seal materials to further improve the working temperature range of the seal, which is called high-temperature seals. Teriburg Sealing System launches Ultra High Temperature Seal.
With its revolutionary structure and design, aircraft manufacturers can develop more efficient engines and achieve more sustainable operation by achieving lower fuel consumption.
Quinn Collett, General Manager of Airframe, said, "The higher the operating temperature of the engine, the greater the thrust obtained under the same fuel quantity conditions, making the engine more efficient and fuel consumption lower. The goal of aircraft designers is to keep the engine running at higher temperatures, and the latest options can operate at temperatures of+315 ℃ and above, significantly higher than previous generation products
Under extreme temperature conditions, specialized fireproof seals help ensure the safety of passengers on board. They are used in fuselage, wings, cable towers, thrust commutators, and engine applications, and play a crucial role in preventing airflow from flowing from one area of the aircraft to another under normal operating conditions. This function is extremely important. However, more importantly, they can also prevent the occurrence of fire accidents. Their function is to control the fire in an area of the aircraft, enabling it to land safely within 15 minutes.
Collet continued: So far, there is no high-temperature fireproof seal that can operate at temperatures up to+315 ℃ and meet all the fireproof sealing requirements of customers. Treburg's ultra-high temperature seal is unique. Its patent pending design overcomes the inherent characteristics of silicone relaxation and compression under high temperature conditions, which is also the main reason for the failure of fireproof seals. Therefore, Treburg's ultra-high temperature seal Seals can be used for aircraft engine applications under high temperature conditions and achieve normal operation
In order to demonstrate the ability of the product under different compression loads, Treburg conducted comprehensive testing on it. In the hot soak test, the performance of ultra-high temperature sealing is superior to other fireproof sealing components. In all cases, it is below the 15% permanent deformation target.
In order to manufacture this product, Treburg Sealing System developed a proprietary method that integrates all components together to create complex geometric shapes. Due to the fact that ultra-high temperature seals do not require thermal protection of sealing components, they further reduce weight, reduce the number of parts, and make assembly easier.
It has been proven that ultra-high temperature seals can operate within the temperature range of -40 ℃ to+315 ℃, while meeting all customer fire sealing requirements. Its design life is 60000 flight cycles (takeoff, flight, and landing), which will vary depending on the application. Ultra high temperature seals can also be used as an alternative product to seals that currently cannot meet all fire sealing requirements, such as operating under high temperature conditions or meeting customer needs, providing seals with a longer service life than their existing seals.
This seal meets the requirements of the "Federal Aviation Standard AC20-135 Fire Test Methods, Standards, and Guidelines for Power Plant Installation and Propulsion System Components" and the "ISO 2685:1998 Aircraft - Environmental Test Procedures for Airborne Equipment - Fire Protection in Designated Fire Zones".
