摘　　要：液压系统的工作可靠性与油液的清洁度有密切关系,固体颗粒和水是液压油中污染物的重要组成成分,因而对于这两相的滤除是提高油液清洁度的关键。该研究基于一种新型超重力净油装置,借助于计算流体力学(CFD)软件FLUENT对该装置内涉及的两类流场——超重力流场及旋流分离流场进行数值仿真分析研究。通过获取旋流场内的固-液分离特性及超重力场内的液-液分离特性,进而对超重力净油装置的净油效果进行综合评估。仿真结果表明,该种新型超重力净油装置能有效去除液压油内5μm左右的固体颗粒污染物和其中含有的水分,该研究的实施为提高我国污染控制水平提供一种新思路。Researches indicate the cleanliness of hydraulic oil is closely related to the reliability of fluid power sys- tem （FPS）. Therefore, it is essential to control the contamination level of FPS especially for removing the solid par- ticle contaminants and moisture contained in the hydraulic oil. Based on a novel higee hydraulic oil purification de- vice, characteristics of high gravity flow field and hydrocyclone flow field are explored with the help of computation- al fluid dynamics （CFD） software FLUENT. The separation efficiency can be obtained in succession. Numerical simulation results show that the higee hydraulic oil purification device can effectively remove solid particles whose diameters is 5 ~m and moisture contained in the hydraulic oil. The research will provide a new way for improving the contamination control level in our country.
