摘要(Abstract):

通过分段测试得到水力旋流器内部各分段压力损失占总压损失的比例情况 ,同时得到脱油型静态水力旋流器流量、分流比分别与压力、压力损失和压降比的拟合曲线近似呈乘幂关系。通过实验测定与理论分析 ,发现旋流器有效分离时底流需保持合理的背压 ,而当溢流压力与底流压力满足适当的比例分配关系时分离效果才较为理想。
Scale correlation of each segment of the total pressure drop was obtained by testing subsection inside hydrocyclones.At the same time,a new kind of power correlation was found by measuring flow rate and split ratio which was connected with pressure, pressure drop and pressure drop ratio on de-oiling hydrocyclones, and we discovered water outlet should keep a rational back pressure when hydrocycloens were in proper function by means of real testing and theoretical analyses.To keep a proper pressure distribution between water outlet pressure and oil vent pressure a better separating effect.
