摘要
针对我国部分梯级泵站存在的流量监测设备不完善、泵站提水效率评估困难的问题,通过分析影响泵站提水效率的主要因素,提出了泵站提水效率评估的模型。将该模型运用于甘肃景泰川电力提灌一期工程的提水效率分析,结果表明,水泵的设计扬程和铭牌扬程匹配良好,模型计算结果和工程实际的运行效率相吻合。
In accordance with the problems caused by the imperfection of flow monitoring equipment and the difficulty from the evaluation on pumping efficiency of pumping station,a pumping efficiency evaluation model is put forward herein through the analysis made on the main factors of the impact on the pumping efficiency,and then the model is applied to the analysis on the pumping efficiency of the Phase I of Jingtaichuan Pumping Irrigation Project in Gansu Province. The result shows that the design head of the water pump is better matched with that of its nominal one,while the calculation result from the model coincides with the actual operation efficiency of the project as well.
