油品含水率在线检测仪的研制

Design of Instrument of Online Measurement of Water-in-oil Percentage

介绍油品含水率检测原理、电容/电压转换方法以及系统设计。实验结果表明,该仪器能够准确、快速地检测出油品的含水率,从而避免了润滑失效所带来的潜在危害。

Water may access to hydraulic and lubricant system due to various reasons, but the lubricant oil in hydraulic system will be out of work because of the high water-in-oil percentage. Traditional measuring instrument of water- in-oil percentage has slower response time and higher costs. The principle of detecting water-in-oil percentage, the method of capacitance-to-voltage conversion and the structure of measurement system are proposed in this paper. It is demonstrated that the device can measure water-in-oil percentage quickly and precisely and avoid the potential hazards.
