Comparing of performance curves and cavitation property with common centrifugal pump of same specific speed was presented in this paper.

同时，针对旋流泵的性能曲线和汽蚀问题与同比转数普通离心泵进行了对比分析。

The performance curves directly reflect the running status of reciprocating pump and its features; the traditional drawing method has the characteristics, a great deal of work and low efficiency.

性能曲线可直观地反映往复泵运行工况及其特性，传统的绘制方法工作量大，且效率低。

Therefore, the change pump performance curves become the main form of energy-saving pumps.

因此，改变水泵性能曲线成为水泵节能的主要方式。
