摘要:
以通启运河泵站5台1 000 kW双向潜水贯流泵为研究对象，基于2026年3次完整潮汐过程1 200余组实测数据，系统分析净扬程变化对机组功率、流量、效率、振动及温度的影响规律，建立扬程-功率-效率特性曲线并开展多机组性能评估。结果表明：净扬程0.08~2.21 m内，机组功率随扬程升高呈非线性增长，单位功率温升0.05~0.06 ℃/kW；低扬程工况流量超设计值25%，效率较高，高扬程工况振动与温度显著上升；4号机组摆度异常，5号机组综合性能最优，3号机组热负荷最高。采用基于实时扬程的优化调度策略，可降低泵站总能耗3%~5%。研究可为潮汐型变扬程泵站安全经济运行提供数据支撑与工程参考。
Abstract:
Taking five 1000 kW bidirectional submersible tubular pumps in the Tongqi Canal Pumping Station as research objects, this paper systematically analyzes the influence laws of net head variation on unit power, flow rate, efficiency, vibration and temperature based on more than 1200 sets of measured data from three complete tidal cycles in 2026. The head-power-efficiency characteristic curves are established, and the performance evaluation of multiple units is carried out. The results show that within the net head range of 0.08-2.21 m, the unit power increases nonlinearly with the rise of head, and the temperature rise per unit power is 0.05-0.06 ℃/kW. Under low head conditions, the flow rate exceeds the design value by 25% with high efficiency; under high head conditions, the vibration and temperature rise significantly. The wobble of Unit 4 is abnormal. Unit 5 has the best comprehensive performance, while Unit 3 has the highest thermal load. The optimal scheduling strategy based on real-time head can reduce the total energy consumption of the pumping station by 3%-5%. This study can provide data support and engineering reference for the safe and economic operation of tidal variable-head pumping stations.
