摘要: 为丰富螺线管型传感器对液压油污染物的检测内容,提出并制作一种基于微流体芯片的对置螺线管型多功能检测传感器。理论推导了对置螺线管线圈的金属颗粒电感检测模型和非金属颗粒电容检测模型。为进一步提高检测灵敏度,试验对比分析了硅钢片对对置螺线管线圈的电感检测和电容检测的灵敏度。试验结果表明,硅钢片能够显著提升对置螺线管线圈的金属颗粒检测灵敏度,60~70 μm铁颗粒和160~170 μm铜颗粒的检测信噪比分别提升127.44%、222.07%,也能提高对置螺线管线圈的非金属颗粒检测灵敏度,但不显著,140~150 μm水滴和240~250 μm气泡的检测信噪比分别提升21.92%、7.95%。该研究对提高螺线管型传感器的液压油污染物检测能力提供了技术支撑,对液压系统健康状态监测以及故障诊断具有重要意义。

Abstract: In order to enrich the detection content of the solenoid sensor for hydraulic oil contaminants, a multi-function detection sensor based on microfluidic chip is proposed and fabricated. The inductance detection model of metal particles and capacitance detection model of non-metal particles are constructed theoretically for the opposed solenoid coil. In order to further improve the detection sensitivity, the effect of silicon steel sheet on the sensitivity of inductance detection and capacitance detection is tested. The experimental results show that the silicon steel sheet can significantly improve the detection sensitivity of the metal particles of the opposing solenoid coil. The SNR of detecting 60-70 μm iron particles and 160-170 μm copper particles is increased by 127.44% and 222.07%, respectively. The detection sensitivity of the non-metallic particles of opposite solenoid coil is not significant, and the SNR of detecting the 140-150 μm water droplet and the 240-250 μm bubble is increased by 21.92% and 7.95%, respectively. This research is expected to provide support for improving the detection capability of the hydraulic oil contaminant of the solenoid sensor, which is of great significance for the monitoring of the health status of the hydraulic system and fault diagnosis.

Key words: opposite solenoid coil, microfluidics, sensor, oil contaminant
