Compressed air aluminum alloy pipeline aerospace manufacturing industry application case
Compressed air plays an extremely important role in the Aerospace manufacturing industry, and the aluminum alloy pressure piping system plays a very good role in the aviation manufacturing industry.
1. Here are some examples of aluminum alloy compressed air pipes used in the aerospace manufacturing industry:
1). Rocket fuel delivery system: In rocket launches, accurate fuel delivery is essential. Aluminum alloy compressed air pipes are used to deliver compressed air to provide power and pressure regulation for fuel delivery. For example, some models of the Long March series of rockets use special aluminum alloy compressed air pipes that can withstand extreme temperature and pressure changes during launch, ensure the stable operation of the fuel delivery system, and ensure the successful launch of the rocket.
2). Spacecraft environment control and life support system: Spacecraft need to maintain a suitable environment in space to protect the lives of astronauts and the operation of equipment. Aluminum alloy compressed air pipes are used in environmental control systems to deliver compressed air to adjust temperature, humidity, and air pressure. For example, the environmental control system of the International Space Station uses aluminum alloy compressed air pipes with good sealing performance and corrosion resistance, and can work stably in the space environment for a long time.
3). Aerospace manufacturing workshop power supply system: In the aerospace manufacturing workshop, various tools and equipment need to be driven by compressed air. Aluminum alloy compressed air pipes provide a stable supply of compressed air for the workshop, with the advantages of easy installation, corrosion resistance, and energy saving. They can improve production efficiency and product quality while reducing maintenance costs and safety risks.
2. Compressed air plays an extremely important role in the aviation manufacturing industry, which is mainly reflected in the following aspects:
Tool power source
A large number of pneumatic tools are used in aviation manufacturing, such as pneumatic wrenches, pneumatic drills, pneumatic grinders, etc. These tools are powered by compressed air and have the advantages of high output power, high speed, light weight, and flexible operation. They can meet the high-precision and high-efficiency requirements in the manufacturing and assembly of aviation parts. For example, in the assembly of aircraft wings, the use of pneumatic wrenches can quickly and accurately tighten a large number of bolts to ensure the strength and reliability of the connection.
Parts processing
Compressed air plays a key role in the processing of aviation parts. For example, in CNC machining centers, compressed air is used to drive the cooling system of the tool, and the heat generated in the cutting area is taken away by high-speed airflow, which reduces the temperature of the tool and the workpiece, improves the processing accuracy and surface quality, and prolongs the service life of the tool. In addition, compressed air can also be used to clean up the chips and dust generated during the processing and keep the working area clean.
Spraying and painting
Surface spraying and painting of aircraft are important links in aviation manufacturing. Compressed air is widely used in spraying equipment, such as spray guns, sandblasting machines, etc. Compressed air is used to evenly spray paint or abrasive onto the surface of the aircraft to achieve the coating of anti-corrosion, aesthetic and special functional coatings. During the spraying process, the pressure and flow control of compressed air directly affect the thickness, uniformity and adhesion of the coating, which is crucial to ensure the surface quality and appearance of the aircraft.
System testing and purging
After the Aerospace manufacturing is completed, the various systems of the aircraft need to be strictly tested and purged. Compressed air is used to perform pressure tests on hydraulic systems, fuel systems, air conditioning systems, etc. to detect whether the sealing and performance of the system meet the requirements. At the same time, after the aircraft is assembled, compressed air is used to purge the pipes, cavities, etc. inside the aircraft to remove residual impurities and dust, and ensure the cleanliness of the aircraft's internal environment and the normal operation of the system.
Environmental control
In the Aerospace manufacturing workshop, compressed air is also used for environmental control systems. For example, compressed air-driven air purifiers and ventilation equipment can filter, purify and circulate the air in the workshop to keep it clean and fresh, providing a good working environment for workers while also helping to reduce the contamination of aviation parts by dust and impurities.
In the Aerospace manufacturing industry, aluminum alloy compressed air pipes provide key support for the development of the industry with their own characteristics. Good corrosion resistance enables them to adapt to complex environments, effectively resist erosion, and ensure the long-term stability of the system. In terms of operation guarantee, high strength and high reliability allow aluminum alloy pipes to withstand high pressure, adapt to extreme working conditions, and ensure trouble-free operation of the compressed air system in key links; excellent sealing performance prevents air leakage and maintains stable system pressure. In terms of manufacturing technology, the easy processing and forming characteristics of aluminum alloy enable it to meet the complex design requirements of aviation manufacturing and flexibly layout pipelines; the advantages of easy installation and low maintenance cost effectively improve manufacturing efficiency and reduce full-cycle costs, which is of far-reaching significance to the high-quality development of the aviation manufacturing industry.
