三坪灌区位于积石山县以北刘家峡水库库区,灌区取水口位置处在河谷与库区的衔接段。因此,形成了急流峡谷与大幅度水位变化并存的特定水源条件。通过方案比较,确定取水枢纽采用泵车方案。经过建成后一年多的运行观测,泵车运行状况良好,具有灵活、稳定、可靠、适应水位大幅度变化;且操作人员少、管理方便的优点。现将有关泵车的布置方式及结构计算介
The Sanping Irrigation District is located in the Liujiaxia Reservoir Area north of Jishishan County. The water intake at the irrigation area is located at the junction between the river valley and the reservoir area. Therefore, the formation of the rapid canyon and large water level changes coexist with specific water conditions. Through the program comparison, determine the water intake hub pump program. After more than a year after the completion of the operation of the observation, the pump running in good condition, with a flexible, stable and reliable to adapt to a substantial change in water level; and fewer operators, the advantages of easy management. Now about the pump layout and structure of the calculation of the medium
