摘　　要：鉴于传统的给水泵数学模型不能很好的解决变速调节及中间抽头、汽蚀等问题，且精度较差，本文依据泵的原理和定律，并借助于给水泵的实际性能曲线，建立了给水泵的通用数学模型。通过实际的仿真算例证明，本模型能准确的反映变转速条件下泵的实际性能，并很好地解决了抽头和汽蚀等问题，具有普遍的适用性。The traditional mathematical model of feedwater pump cannot solve problems such as variable-speedcontrol, interspace water extraction and vapor erosion accurately.A new type of universal mathematical model offeedwater pump is built in this article based on its practical performance curve and the theories and principles ofthe pump.Practical simulation calculation prove that the universal model can solve the probleins above mentioned with great accuracy and it can be widely and generally used.
