摘要
从离心泵变速调节原理入手 ,探讨了当泵站取水点水位发生变化时以维持泵系统流量不变为目的所确立的水位与泵转速、扬程和能耗对应的关系及计算方法 。
The problem to maintain stable discharge of pumping equipment in case when the water level at the suction point is fluctuant is discussed. As a base of speed control of centrifugal pump, the relationships and calculations of pumping parameters such as rotation speed, delivery head and power requirement to fluctuant water level at expected constant discharge must be assured. The power consumptions of two ways, the pump speed control and the valve discharge regulation are compared.
