摘要

为了研究进出口压差、进口含气率对双螺杆多相混输泵输出流量和消耗功率的影响

设计并搭建了双螺杆多相混输泵的测试实验台

在不同进出口压差及不同进口含气率工况下

对双螺杆多相混输泵的输送特性进行了实验测试。通过对实验数据的理论分析

得到了双螺杆多相混输泵输出流量及消耗功率与进出口压差、进口含气率的关系

结果表明:在纯液工况下

进出口压差从0.4 MPa增加到1.0 MPa时

双螺杆多相混输泵输出流量降低了3.7%

消耗功率增加了45.3%; 在混输工况下

进口含气率从20%增加到90%

进出口压差分别为0.4 MPa和1.0 MPa时

双螺杆混输泵的输出流量分别减少了18.7%和25.7%

消耗功率分别减小了2.5%和9.3%。理论计算输出流量及理论计算消耗功率与实验测试值在含气率低于80%时吻合较好。

Abstract

To examine the effect of pressure differences and gas void fractions(GVF)on volume flow rates and power consumptions

an experimental investigation was conducted under different operating conditions based on a twin-screw multiphase pump prototype. Experimental results show that

for liquid pumping only

the flow rate decreased by 3.7% and the power consumption increased by 45.3% when the pressure difference increased from 0.4 MPa to 1.0 MPa. For multiphase fluid pumping

at the pressure difference of 0.4 MPa and 1.0 MPa

the flow rate decreased by 18.7% and 25.7% with an increase of gas void fraction from 20% to 90%

respectively

and the power consumption decreased by 2.5% and 9.3%

respectively. The theoretical simulation results agree reasonably well with the experimental data at GVF from 0 to 80%.
