橡胶坝充排水系统使用水泵作为充坝、坍坝的动力设备,水泵选型的合理性是橡胶坝工程正常运行的关键。充坝时水泵的净扬程为正值而坍坝时水泵的净扬程为负值。因此,水泵选型时应充分考虑水泵在不同工况下净扬程对水泵选型的影响,合理计算确定水泵的扬程及范围,使选定的水泵运行在正常工况点范围内。
Rubber dam filling and drainage system uses the pump as filling dam, sluicing dam power equipment, pump rationality is the key to the normal operation of the rubber dam project. When filling the pump, the net lift of the pump is positive and the net lift of the pump when the dam collapsing is negative. Therefore, the pump selection should take full account of the pump under different conditions net head lift on the selection of the pump, a reasonable calculation to determine the pump head and range, so that the selected pump is operating within the normal operating point range.
