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.

在研究旋流器轴向速度分布规律的基础上，分析了短路流与循环流的形成原因，试验研究了改变操作参数，即改变入口流量Qi与分流比F对轴向速度场的影响认为短路流与循环流是由旋流器结构决定的，很难完全消除，它们干扰了旋流腔和大锥段的流场，在一定程度上也影响了分离精度试验结果表明，加大入口流量Qi与分流比F，并将其控制在一定范围内，便可提高分离效率这项研究对水力旋流器分离机理的认识与实际应用均有重要意义
