摘　　要：对油品含水率进行检测是保障航油安全的重要环节,对航油进行油水界面检测并采用自动方式进行精准放沉是当前航油存储管理发展的必然趋势。在现有油水分析技术的基础上,针对航空煤油的存储特点,提出基于电容检测技术的油水分界面测量方法,以实现航油储油罐底油水界面的精确测量,并结合工艺流程与现场控制技术实现罐底水分的自动放沉。结果表明:该测量方法能够极大地提高油水界面测量准确性及放沉作业自动化水平,从而减少人工和煤油过度放沉带来的生产经营成本,提高油库信息化管理水平。Detection of moisture content in oil products is an important link to guarantee the safety of aviation fuel. Thus, the oil-water interface measurement of aviation fuel and accurate drainage of water in an automatic way is the inevitable trend for development of aviation fuel storage and management. By comprehensively researching the existing oil-water analysis technology, an oil-water interface measuring method based on the capacitance detection technology was put forward with consideration given to the storage characteristics of aviation kerosene, so as to accurately measure the oil-water interface at the bottom of the aviation fuel tank, and in combination with the process flow and the site control technologies, to realize the automatic drainage of water at the bottom of the tank. The results show that, the measuring method can greatly improve the accuracy of oil-water interface measurement and the automation of water drainage, further to reduce the operation cost resulted from the labors and excessive discharge of kerosene and to improve the information management of oil depot.
