摘要
针对润滑油中危害最大物质之一的固体微粒，建立了润滑油介电动力学分离流态实验装置系统，研究了该方法主要工艺技术参数：电场强度和流速等。对国内外几种知名品牌润滑油中的固体微粒进行了分析与对比，并运用介电动力学方法对这些润滑油进行了精制。结果表明：该方法能使国产润滑油中微米级的固体微粒从150～800个／mL减少到5～40个／mL，脱除率95％～98％，产品质量从1530标准的14～16级提高到9～12级以上，达到或超过了国外名牌产品的洁净度质量。该分离方法为提高润滑油的高洁净度质量提供了一种新的技术途径。
For solid particles being the most deleterious matter in lubricating oils, the dielectrophoresis separation process system for removing the solid particles was established. And the process parameter such as electric field intensity and velocity of flow was studied. Several domestic and overseas lubricating oils were analyzed and contrasted, and then refined by the dielectrophoresis separation process. As a result, 150～800 solid particles in each 1-mL in domestic lubricating oils can be reduced to 5～40 with this method; the rate of removal is from 95% to 98%, and the quality of the domestic lubricating oils is improved from grade 14～16 to over 9～12 in ISO, which has reached or exceeded the quality of the overseas lubricating oils. It is believed that this separation technology gives a new way to improve the quality of lubricating oils.
