摘　　要：针对多台离心式水泵作为动力源的水流量标准实验装置,利用变频调速技术,设计一套具有显著节能效果的多变频调速系统,保证离心泵工作在高效区,实现转速调节,克服流量调节阀的节流损失。解决了高位水塔供水产生水塔溢流造成的严重能量浪费。水流量标准实验装置供水系统也进行了技术改造。运行结果表明,各项性能指标达到预期的目的。Aiming at many centrifugal water pumps as motive power in the water-flow standard apparatus, using variable-frequency to change the rotational speed, designing a set variable-frequency system of saving re sources remarkably, making sure centrifugal water pumps work at the high efficiency area, realizing the rota-tional speed＇s regulation,and overcoming flow-raegulation valve＇s throttle loss should be done. The system solves serious energy waste of water tower＇s overflow, thereby, reforming the water-flow standard apparatus. As a result, a variety of properties target can he achieved for the expectable purpose.
