“…Kirst et al [18,19] optimized the performance of the vertical pump system by installing a baffle wall after evaluating the inflow conditions in the structure of the pump intake of a compact sewage pump station model, which was verified by the experiment. As for underground pumping stations, research on their complicated internal flow pattern has not been carried out systematically, and the existing research on the underground pumping station mainly focuses on the civil structures [20], layout [2], and stability [21], etc. In this context, the present paper attempts to answer the following questions:…”

In order to provide specific references and suggestions for the design and operation of underground pumping stations, in this paper, an experimental model of an underground pumping station, including 4 pumps and 2 pump intakes (primary and secondary), was obtained through similitude of fluid mechanics. The phase diagrams of various vortices, in terms of different dimensionless numbers are presented, which can reveal their appearance and evolution process. Three specific cases with different vortex flows were analyzed. The experiment results may provide a reference for the current design guidelines for underground pumping stations.

In order to quantitatively study the relationship between the performance of a pump and the related hydraulic phenomena in a pump intake of a model pump station, a model test was carried out in the present paper. The results show that when the dimensionless water level (water level/diameter of the pipeline: W/d) WL*≥5.46, the influence of the water level on the performance of the pump can be ignored, and the operation of the pump is stable. When WL*=5.15, the performance of the pump decreases deeply, the dimensionless flow rate (actual flow rate/reference flow rate under standard working condition) Q* can be as low as 0.79, and the pump becomes noisy. Finally, when WL *<5.15, although the impeller is still rotating and the input power is unchanged, the pump no longer pumps water.
