铁谱技术是从润滑油等工质中分离和分析磨损粒子的新技术。其原理是在高梯度的强磁场作用下,使在润滑油中的磨粒及沾染物分离,按粒度大小依次沉积到一块透明的玻璃基片上,然后对沉积粘度进行光学显微定性观察和对磨粒进行定量测量。这一技术为摩擦磨损机理研究和机械设备的工况诊断、磨损监测、故障预报以及油质评价等开辟了一个新领域。北京型内燃机车的12V240ZJ柴汕机台架磨合规范十几年来一直为17.5小时,这一规范是否先进合理,我们用分析式铁谱仪、直读式铁谱仪和专用形貌仪对五台柴油机磨合期油样内的磨粒浓度、形态、尺寸、数量、粒子分布等进行实验和分析观察并结合形 Ferrography is a new technique for separating and analyzing worn particles from working fluids such as lubricants. The principle is that under the action of a high gradient of strong magnetic field, the abrasive particles and contaminants in the lubricating oil are separated and deposited on a transparent glass substrate in order of particle size, and then the deposition viscosity is observed by optical microscopy and the Grit quantitative measurement. This technology has opened up a new field for research on the mechanism of friction and wear, diagnosis of working condition of machinery and equipment, wear monitoring, fault prediction and oil quality evaluation. Beijing-type diesel locomotive 12V240ZJ Chaishan machine bench running specifications over the past decade has been 17.5 hours, this specification is advanced and reasonable, we use analytical iron spectrometer, direct reading spectrometer and special profilometer on the five Diesel oil run-in period of the abrasive particle concentration, shape, size, number, particle distribution and other experiments and analysis of observation and combined with the shape
