| 中文摘要: |
| 针对滴灌中黄河水泥沙含量高的问题,根据其基本特征,研制了适于黄河水泥沙分离的碟式分离机,选用FXJ-150-I型旋流器,将分离机与旋流器串联进行泥沙分离。通过三因素二次正交旋转回归试验,考察了底流口直径、旋流入口压力、转鼓转速对溢流颗粒D50的影响,得出D50与影响因素的回归模型。结果表明:底流口直径和旋流入口压力对D50的影响极显著(P<0.01),转鼓转速对D50的影响显著(P<0.05);获得较小D50的最佳结构和操作参数是底流口直径为14 mm,旋流入口压力为0.06 MPa,转鼓转速为3 800 r/min。 |

| Aimed at the problem of silt in the Yellow River water for agricultural drip irrigation, a dish separator is designed and manufactured in accordance with the major characteristics of silt in the Yellow River and the FXJ-150-I hydrocyclone is chosen. The separator and hydrocyclone are arranged in series for separating silt of the Yellow River wa-
ter. Half-content diameter D50 was selected as experimental target, with three-factor quadric orthogonal regression com-posite experimental design, the influences of underlow port diameter, inlet pressure and drum rotation speed were inves-tigated, and a regression equation with high reliability was obtained. The results show that underflow port diameter and inlet pressure have very significant influence on separation efficiency (P<0.01), and drum rotation speed has signifi-cant influence (P<0.05). The optimum parameters are 14mm of underflow port diameter, 0.06 MPa of inlet pressure and 3 800 r/min of drum rotation speed. |
