轴流泵的性能分析及其运行调节

轴流泵是常用的一种泵型，由于具有低扬程、大流量的特点，在低洼区和平原地区的排涝灌溉中得到广泛的应用，为了合理选择和使用轴流泵，必须了解轴流泵的有关性能，正确分析轴流泵的性能曲线，以便使轴流泵经常在高效区域内工作，并且使轴流泵在充水、起动、运行和停止动作中都能正常进行。文章对此作了较为详细的分析。

Analysis on Performance and Operational Adjustment of Axial-flow Pump

Axial-flow pump is a kind of pump which is widely used in irrigation and drainage of low-lying areas and plane areas because of its low head and large flow rate. With the purpose of choosing and using rationally, we must know about its performance and analyze its performance curve correctly. Thus we should make axial-flow pump work in the region of high efficiency and operate normally in the periods of water filling, starting, operating and stopping.
