Liquid jet pumps are widely used in various industrial applications for fluid mixing, circulation, and transport. The efficiency and performance of liquid jet pumps play a crucial role in determining their overall effectiveness and economic viability. The performance of liquid jet pumps is primarily affected by parameters such as motive fluid pressure, nozzle design, and entrainment ratio. Liquid jet pumps exhibit a notable drawback in terms of comparatively lower efficiency when compared to alternative pump types. The reduced overall efficiency of liquid jet pumps stems primarily from energy dissipation incurred during the entrainment process. To address this obstacle, a water-water loop system was implemented in conjunction with a liquid jet pump, followed by the introduction of drag-reducing polymers (DRPs) into the suction flow of the liquid jet pump using a specific configuration. This configuration led to a significant reduction in drag within the liquid jet pump, raising its efficiency in some cases from 13.8% to 26.7% with a drag reduction of 46%, subsequently improving its overall performance. The resulting enhancement was evaluated using various efficiency models documented in the existing literature to comprehensively assess the overall performance of the liquid jet pump. A new interpretation of jet pump efficiency has been shared, along with a comparison of the various efficiencies.
液体喷射泵广泛应用于各种工业领域，用于流体混合、循环和输送。液体喷射泵的效率和性能在决定其整体有效性和经济可行性方面起着至关重要的作用。液体喷射泵的性能主要受诸如工作流体压力、喷嘴设计和引射比等参数的影响。与其他类型的泵相比，液体喷射泵在效率相对较低方面存在明显缺点。液体喷射泵整体效率降低主要源于引射过程中产生的能量耗散。为解决这一障碍，在液体喷射泵的基础上实施了水 - 水回路系统，并采用特定配置将减阻聚合物（DRP）引入液体喷射泵的吸入流中。这种配置使液体喷射泵内的阻力显著降低，在某些情况下，其效率从13.8%提高到26.7%，减阻率达46%，从而改善了其整体性能。使用现有文献中记录的各种效率模型对所产生的性能提升进行了评估，以全面评估液体喷射泵的整体性能。同时分享了对喷射泵效率的新解释以及各种效率的比较。
