摘　　要：研制出1种监测不透光润滑油中磨粒图像可视在线铁谱仪,介绍了其中关键零部件(混合磁铁和磨粒探测单元)的组成及其工作原理,并进行了性能试验研究.结果表明,所研制的图像可视在线铁谱仪具有采集不透光润滑油中尺寸大于10μm磨粒图像的功能,其稳定性、线性度和重复性较好,能够通过磨粒在线反映机器磨损的状态.A novel on-line ferrograph for monitoring wear particles in opaque lube is developed. The basic principle of on-line ferrograph and its key parts, namely hybrid magnet, and wear particle detector is introduced, and experiments were performed. Results show that the on-line ferrgraph is capable of collecting wear particles large than 10μm from lubricating oil, its stability, linearity, and repeatability are satisfactory. This apparatus can on-line monitor wear state of machinery friction.
