即将发布实施的HB5930-86《飞机液压系统工作液固体污染度分级》是飞机液压系统污染控制工作的一项基础标准,它是开展污染测试工作面临的第一个要解决的问题。该标准的制订与发布将结束多年以来沿用的绸布过滤,目测检查的落后方法,继而代之的是用先进的技术科学地评定油液的污染等级,从而使飞机液压系统的污染控制工作,能在先进的技术指导下以适应现代飞机的要求。
The forthcoming implementation of HB5930-86, “Classification of Solid Pollution Degree of Aircraft Hydraulic System Working Fluid” is a basic standard for aircraft hydraulic system pollution control. It is the first problem to be solved in carrying out pollution testing. The formulation and promulgation of this standard will put an end to the outdated methods of silk filtration and visual inspection that have been used for many years and then replace them with advanced technology to scientifically assess the pollution level of oil so as to control the pollution of aircraft hydraulic system, Under advanced technical guidance to meet the requirements of modern aircraft.
