便携式金属磨粒分析仪的研制

Development of a Portable DebrisAnalyzing Instrument

在对直读式铁谱仪进行改进的基础上，研制了一种新型便携式金属磨粒分析仪。介绍了磨粒分析仪监测原理及各部分的结构，并利用该仪器探讨了铁磁性颗粒和弱磁性颗粒在沉积管内的沉积规律。结果表明，金属磨粒分析仪能同时监测这两类性质不同的颗粒。文中还提出了一种新的可用于监测弱磁性颗粒的定量指标，并重新定义总磨损量参数。

A new kind of portable metal debris monitoring instrument(MDMI) was developed on the base of improving the old direct reading ferrography. The theory of monitoring and every part of the instrument were introduced in the paper. Both submagnetic debris and magnetic debris were tested in the precipitator with MDMI. The results showed that these two kinds of debrises can be monitored by the monitoring instrument. A new quantitative index used for submagnetic debris was put forward, and the parameter of total wear volume was also redefined.
