摘要
介绍了低比转速离心泵水力设计和结构设计研究现状,分析了低比转速离心泵水力性能方面存在的效率较低、扬程曲线易出现驼峰和轴功率易过载等问题产生的原因及解决办法,对各水力设计方法进行了评述。讨论了低比转速泵发展中有待解决的问题,并对发展趋势作了前瞻,为低比转速离心泵的研究与设计提供参考。
The hydraulic design theory and configuration status of low-specific-speed centrifugal pumps are summarized. The main problems of pumps in hydraulic characteristics such as low pump efficiency, humble head-flow curve and easily overload brake horsepower etc, and their countermeasures developed in recent years including greater flow design and non-overload theory etc, are introduced thoroughly. Some problems under settlement in the development of low-specific-speed centrifugal pumps are discussed and the trends for further development are also put forward.
