Based on an analysis of distribution pattern of hydrocyclone"s axial velocity, by changing the inlet flow rate Qi and split ratio Fand making an investigation in the effect of Qi and F on axial velocity field, the factors causing the forming of short-cut circuit and circulating flow are found. It is considered that the short-cut circuit and circulating flow are produced by the structure of the hydrocyclone, and can"t be eliminated completely, though they interfere the flow field inside a hydrocyclone and affect the separation accuracy. Test results show that, by increasing Qi and F and controlling them in a certain range, the separation efficiency of the hydrocyclone can be improved.

With the higher requirement of the low energy lost of hydrocyclone, especially single-level hydrocyclone inaccessible separation standard, industrialization requirements are carried out by series-parallel connection of multilevel hydrocyclone. Thus, the utilization of uniflow hydrocyclone becomes more and more abroad when the hydrocyclone changes its role from primary ultimate separation equipment to advance separation equipment.
