铁谱分析技术特点
Technical characteristics of Ferrography
1)由于能从油样中沉淀1—250μm尺寸范围内的磨粒并进行检测，且该范围内磨粒最能反映机器的磨损特征，所以可及时准确的判断机器的磨损变化。
1) because the abrasive particles in the size range of 1 to 250 mu m can be precipitated from the oil samples and tested, and the abrasive particles in this range can reflect the wear characteristics of the machine most, so the change of the wear of the machine can be judged in time and accurately.
(2)可以直接观察、研究油样中沉淀磨粒的形态、大小和其它特征，掌握磨擦付表面磨损状态，从而确定磨损类型。
(2) we can directly observe and study the shape, size and other characteristics of the precipitated particles in the oil sample, grasp the wear state of the friction surface and determine the wear type.
(3)可以通过磨粒成份的分析和识别，判断不正常磨损发生的部位，铁谱仪比光谱仪价廉，可适用于不同机器设备
(3) the location of abnormal wear can be judged by the analysis and identification of abrasive grains. The Ferrograph is cheaper than the spectrometer and can be applied to different machines and equipment.
