Abstract:
Tubular pumping systems which are widely applied in the low and extra-low head pumping stations usually adopt the structure of straight outflows in the conversional design. In order to meet the requirements of low head, short annual operation time, and high safety and reliability in the municipal flood control pumping stations, five structural types of tubular pumping systems with siphon outflows were proposed, and they have the advantages of simple structure, reliable shut-down device, convenient installation and maintenance, and cheap cost of operation and management. Under the condition of unchanged model pump, CFD simulation technology was used to perform the numerical analysis, optimal hydraulic design, and performance prediction of various tubular pumping systems with siphon outflows. According to the optimization results, a comparison test of the shaft-type tubular pumping systems with straight and siphon outflows was carried out in the model test stand with high accuracy. The model test results showed that hydraulic performances of two outflows are similar so that the structural types of straight and siphon outflows are both suitable for the low head pumping station when the tubular pumping system is used. For the extra-low head pumping station, the tubular pumping systems with siphon outflows have significant advantages compared with those with straight outflows.
