在锦西乌金塘水源供水工程，水源泵站采用了并联调速水泵机组，以适应乌金塘水库水位变化，通过近５年的生产运行，达到了节能和稳定运行的效果，现将设计中一些体会介绍如下。１调速泵的节能原理改变水泵的转速，可以适应水源水位的变化，使水泵始终与水流阻力相适应，做... In Jinxi Wujintang Water Source Water Supply Project, the water source pumping station adopts a parallel-connected speed-adjusting water pump unit to adapt to the water level change of the Wujintang Reservoir. Through nearly five years of production operation, the energy-saving and stable operation effect has been achieved, and some of the designs will now be designed. Experience is described below. 1The energy-saving principle of speed control pump changes the speed of the water pump, can adapt to the change of water source water level, so that the water pump is always compatible with the flow resistance, do...
