一、概述 航空产品的液压系统中,除金属导管外,还选用了规格不一数量较多的橡胶软管。通常可分低压、中压、高压软管。对于中、高压软管,为确保它承受相当大的工作压力,在它的结构中敷设了钢丝层。我厂某机上采用的高压橡胶软管在装配,典型试验和使用过程中,多次发现钢丝生锈,外胶层起鼓、渗油等严重质量问题。上述问题我厂曾多次向胶管承制厂通报信息,承制厂于一九七八年研制成功镀铜钢 First, an overview of the hydraulic system of aviation products, in addition to the metal conduit, but also the choice of a larger number of different rubber hose. Can be divided into low pressure, medium pressure, high pressure hose. For medium and high pressure hose, in order to ensure that it is subjected to considerable work pressure, lay the wire layer in its structure. I plant a machine using high-pressure rubber hose assembly, the typical test and use of the process, many times found rusty wire, the outer drum from the drum, oil leakage and other serious quality problems. I plant the above problems have repeatedly to the hose factory informed of information, manufacturing plant in 1978 successfully developed copper-coated steel
