| 摘要：原油含水率是原油的一项重要指标。原油含水率分析仪就是用来测量原油含水率的仪器。原油含水率分析仪的种类很多，工作原理的种类也很多。本次课题是利用电脱法改进和设计出满足实际需求的原油含水率分析仪。本次课题的主要难点有两点，一是原油含水率测试仪结构的设计，由于原油含水率分析仪需要经常的拆卸，测试仪有可能用在高压的环境下，所以必须对测试仪结构进行校核，使其满足应力要求。二是电极板结构的设计。原油含水率测试仪内电场的分布必须满足能够使原油中的水分子快速的极化，从而使水分子快速的聚集沉降达到油水分离的目的。4936 关键字： 原油含水率测试分析仪；结构设计；ANSYS The design of the Moisture content tester of crude oil Abstract：The moisture content of the crude oil is an important indicator of crude oil. Moisture content tester of crude oil is used to measure the moisture content of the crude oil instruments. Many different types of Moisture content tester of crude oil. There are many types of working principle. The main task is the use of the Electric field improvements and design meet the actual demand of Moisture content tester of crude oil. The main difficulty of the subject for two. First, the moisture content of the crude oil tester structural design, Crude oil moisture analyzer need frequently Disassembly, Tester may be used in the high pressure environment, so It is necessary to check the structure of the tester. To make it meet the stress requirements. The second is the design of the electrode plate structure. The electric field distribution in the moisture content tester of crude oil must meet to be able to make rapid polarization of the molecules of water in crude oil, So that the water molecules quickly gathered sedimentation, To achieve the purpose of the oil-water separator.
