在航空飞行器及工程机械等液压系统中,对动力介质的清洁度往往有非常严格的要求,为此必须在传输管路中对于动力介质予以过滤,以限制较大颗粒的杂质进入液压元件而影响动态性能。因为无纺布可以满足过滤时强度的要求而广泛用于制作管路中的过滤材料.为满足滤液技术条件的要求,须对其孔径大小进行测量,否则,将直接影响到产品的出厂。无纺布类似于滤纸,其网眼的形状无规则,无法用
In the aviation aircraft and construction machinery and other hydraulic systems, the cleanliness of the power medium often have very strict requirements, for which must be in the transmission line to filter the power medium to limit the larger particles of impurities into the hydraulic components and influence Dynamic performance. Because the non-woven fabric can meet the requirements of filtration strength, it is widely used to make the filter material in the pipeline.To meet the technical requirements of the filtrate, the pore size must be measured, otherwise it will directly affect the product’s factory. Nonwovens similar to filter paper, the shape of the mesh irregular, can not be used
