叶片可调式水泵流量在线调节的研究

Study on Adjustable-Blade Pump for Flow on-Line Autoregulation in Diversion Works

为了在大型输水工程中实现全系统的流量平衡 ,提出了叶片可调式流量在线调节方式 ,即来流有扰动时 ,通过自动调节叶片角度改变泵的流量特性 ,保持泵站前池水位不变而实现新的流量平衡。应用此方法编制了过渡过程仿真程序 ,并讨论了调节器参数对调节能力的影响。

In order to keep flow equation for the whole system in large_scale diversion works, each pumping station should have ability of autoregulation. A new method of flow on_line autoregulation based on adjustable_blade pump was offered. When there is turbulence of the flow, by adjusting the blade of the pump to change the discharge characteristic, the system will get new equation with constant water height. Transist simulation of single pumping station was studied and the effect of several parameters was compared.
