Abstract: Structure and working principle of dynamic hydrocyclone are introduced.Based on deepening research of separating mechanism and performances of dynamic hydrocyclones,it was confirmed that the better separation effect could only be obtained by reasonably defining its structural parameters.Its optimical design procedure of main structural parameters is introduced in detail.The contrasting analysis of static and dynamic hydrocyclones used on oil-water separation manifests that the dynamic ones have obvious priority.Its successful research and manufacture is beneficial to the deepening research of its mechanism and flowfield measurement,and is important for its application in oil fields.

Key words: dynamic hydrocyclone, structural parameter, separation efficiency, optimical design, parametric modeling
