Different types of aircraft engines have different requirements for seals due to differences in design, performance and operating conditions. Some high-performance, high-thrust engines may require higher reliability of seals and relatively short maintenance intervals.

If the aircraft is often operated in harsh climates, such as high temperatures, high humidity, high altitudes, or extreme cold regions, the seals may be more affected. In high-temperature environments, seals may be more susceptible to aging and failure; High humidity can lead to seal corrosion; Low air pressure at high altitudes can affect the sealing performance of the seal. As a result, engine seals may have shorter maintenance intervals for aircraft operating in these harsh climatic conditions.

Different missions also have an impact on the load and operating conditions of the engine. For example, aircraft with frequent short takeoffs and landings may have shorter maintenance intervals due to higher engine starts and stops, and seals are subject to greater thermal shock and mechanical stress. In long-haul aircraft, the engine runs for a longer time in a relatively stable working state, and the maintenance interval of the seal may be relatively long.

Professional training is provided to maintenance personnel to familiarize them with the installation, inspection, and maintenance methods of seals. At the same time, maintain close contact with aircraft manufacturers and suppliers for technical support and up-to-date maintenance information.
