【摘要】 通过试验研究双锥油水分离旋流器的压降比和分流比两个无因次参数之间的关系，以及结构参数对两者关系的影响，发现压降比和分流比的关系仅与旋流器的结构参数有关，与操作参数无关；压降比和分流比的关系是非线性的，其非线性程度随溢流口直径的减小而增强，当分流比较小时近似处理为线性会造成较大误差；尾管直径比对压降比和分流比关系曲线的起点和变化趋势影响较大；进口尺寸对压降比和分流比关系曲线的起点影响很大，对其变化趋势影响较小；小锥对压降比和分流比关系曲线的起点影响较明显，对其变化率影响不大，大锥则仅对变化率略有影响。更多还原

【Abstract】 The relation between the pressure drop ratio and fractional flow ratio of a twin-cone hydrocyclone and the effect of geometric paramters of the hydrocyclone on this relation are investigated by means of test. The relation between the pres sure drop ratio and the fractional flow ratio is only related to the geometric parameters, and has nothing to do with the working paramters. There is a nonlinear correlation between the pressure drop ratio and fractional flow ratio. If they are taken as linear correlation while the fractional flow ratio is rather small, big error will be resulted. The tail pipe diameter ratio has great effect on the starting point and tendency of the correlation curve of the pressure drop ratio and fractional flow ratio; the inlet size has great effect on the starting point, but has little effect on the tendency; the small cone has obvious effect on the starting point, but slight effect on the variation rate of the curve; while the big cone only has slight effect on the variation rate.更多还原
