油液在线监测是目前装备润滑磨损状态监测技术发展的重要方向，而监测仪器的开发是这一监测诊断技术研究热点。针对现代远洋船舶流动性工作特点及机械润滑磨损状态监测实时性要求，开发一套集油液磨粒监测和黏度检测的在线监测装置。装置具有结构紧凑、尺寸小、安装方便等特点。调试试验分析表明，该集成装置具有良好的稳定性，能快速实现油液磨粒含量、黏度趋势分析及超限报警。该油液在线监测装置的集成实现，为后续集成如水分、颗粒计数指标以及温度、压力等状态参数提供了研发基础。 Oil on-line monitoring technique is now an important development direction of the equipment lubrication and wear monitoring technology, developing the monitoring instruments is one of the research hotspot in this field of the monito- ring and diagnosis technology. Aimed at the flowability characteristics for the modem ocean-going vessels and real-time re- quirements of mechanical lubrication and wear condition monitoring, a set of oil on-line monitoring device integrating fer- rography detector with viscosity sensor was developed. This device has the advantages of compact structure, small size, and easy installation. Testing analysis shows that the integrated device has good stability, can quickly carry out the trend analy- sis of the wear particle concentration and the oil viscosity, and realizes the limit alarm. The integration achievement of oil on-line monitoring device provides a basis for research and development for the subsequent parameter integration, such as moisture, particle counter and temperature, pressure and so on.
