摘要: 提出一种基于微流体芯片的新型油液多污染物区分检测方法,该方法设计的传感器由一个直通道微流体芯片以及嵌入芯片中的两个相同的单层线圈组成,不仅从电感原理对船舶液压油中的铁磁性和非铁磁性金属颗粒进行区分检测,也能从电容原理对油液中的水滴和气泡进行区分检测。相较于传统单线圈电感传感器,该双线圈传感器不仅能够检测多种参数,而且具有更高的分辨率。从检测原理对该方法进行了仿真及分析,然后用该传感器搭建检测系统对油液中的多种污染物进行检测试验,在试验中成功检测到了油液中40 μm的铁颗粒和110 μm的铜颗粒;作为电容传感器时能够检测100 μm的水滴和180 μm的气泡。该研究对船机油液污染物的快速区分检测提供了技术支持,这对于船舶机械系统的故障预防与诊断具有重要意义。

Abstract: A novel method based on a microfluidic chip is presented for the detection of multi-contaminations in marine lubricants. The sensor designed using this method consists of a straight microchannel and two single-layer coils, which can detect not only ferromagnetic and non-ferromagnetic particles in oil as an inductive sensor but also water droplets and air bubbles in oil as a capacitive sensor. Compare with the conventional single coil inductive sensor, the double-coil sensor not only detects two kinds of parameters but also offers higher resolution. The method is simulated and analyzed from the detection principle. Then the sensor is used to build a detection system to detect the multi-contaminations in the oil. In the experiments, we detected 40 μm iron particles and 110 μm copper particles successfully. Meanwhile, as a capacitive sensor, we are able to detected 100 μm water droplets and 180 μm bubbles in oil. This study is expected to provide supports for the rapid detection of multi-contaminants in marine lubricants, which is of great significance for the prevention and diagnosis of marine mechanical system faults.
