1防止液压中混入杂质液压传动系统以油作为传递能量的工作介质,在正确选用液压油以后,必须使液压油保持干净,防止混入杂质和脏物,因为在液压传动系统所用的各种泵、阀类元件中,相对运动部件都有很好的配合表面,精度很高。这样的配合表面间的间隙都很小,此外,在液压元件中也有不 1 to prevent the mixing of impurities in hydraulic Hydraulic transmission system with oil as the working medium to transfer energy, the correct selection of hydraulic oil, the hydraulic oil must be kept clean to prevent mixing impurities and dirt, because the hydraulic drive system used in a variety of pumps, Valve components, the relative movement of parts have a good match with the surface, high precision. The clearance between such mating surfaces is small, and in the case of hydraulic components too
