随着航空工业的发展,对航空仪表、电器的要求越来越高。为适应高空、高速、高温、湿热和冰冻各种恶劣条件,同外从五十年代起,航空仪表电器产品就采用了密封或半密封结构,同时装配中的超净技术也不断被采用。六十年代密封技术迅速发展并被广泛应用,大大提高了产品质量,延长了使用寿命及封存期限。目前国外不少产品采用密封结构,并实现了小型化。从对国外产品的分析看我国航空仪表电器产品,为
With the development of the aviation industry, the requirements for aviation instruments and appliances are getting higher and higher. In order to meet the high altitude, high speed, high temperature, hot and humid conditions and a variety of harsh conditions, with the same since the fifties, aviation instrumentation electrical products on the use of a sealed or semi-sealed structure, while the assembly of clean technology has also been used. Sealing technology in the sixties rapid development and is widely used, greatly improving product quality, extending the service life and storage period. At present, many foreign products using sealed structure, and achieved a miniaturization. From the analysis of foreign products to see China’s aviation instrument electrical products,
