目前,水电站机组的技术供水系统多采用水泵供水方式为:尾水(管)取水→水泵增压→自动滤水器过滤→各冷却器→排水汇集→下游尾水。在技术供水系统设计中,如何选择合理的水泵流量和扬程是关键。在选择水泵时,有些人只是简单地计算从取水口到排水口之间的水头损失(包括局部损失和沿程损失),然 At present, the technical water supply system for hydropower units mostly adopts the water supply method of the water pump as follows: tail water (pipe) water intake → pump pressurization → automatic water filter filtration → coolers → drainage collection → downstream tail water. In the technical water supply system design, how to choose a reasonable pump flow and lift is the key. When choosing a pump, some simply calculate the head loss (including local loss and loss along the way) from the water intake to the water outlet
