摘要
本文分析了离心式水泵在额定与非额定转速下、以及不同特性的水泵并联、同型号水泵在不同转速下并联、同特性水泵在不同泵房内并联等复杂条件下运转的特点，给出了相应特性曲线的拟合方程的确定方法。
The paper analyzes the rotational characteristics of the centrifugal pump on the complex conditions, such as the rated and unrated rotational speed, the parallel connection of different characteristic pumps, the parallel connection of the same type pumps at the different rotational speed, the parallel conduction of the same characteristic pumps in different pump houses, and so on, and derivates the fitting equation of characteristic curve.
