含沙量对高扬程梯级提水泵站输水能耗的影响研究

The Influence of Sediment Concentration on Water Consumption in the High Lift and Rundle Irrigation Pumping Station

根据现场调查及泵站多年运行试验数据,通过实例计算含沙量对高扬程梯级提水泵站输水能耗影响并进行了分析.结果显示清水与高含沙水流对泵站输水能耗影响有很大不同.提出在泵站系统中设置沉砂池以减少含沙量,提高泵站运行效率.

Based on site investigation,the operation data of pumping station-for many years running,and the calculation and analysis of the influence of sediment concentration on water consumption in the high lift and rundle irrigation pumping station. The results show that clean water and high sediment concentration have a conspicuous effect on the pumping station. It is suggested that sand pools can be built in the pump station system so as to reduce the sediment concentration and enhance its onerating efficiency
