旋流泵(也称无堵塞泵)由于结构特殊(图1),工作原理与普通离心泵有很大区别。虽然这种泵在国内外已得到了较为广泛的应用,但关于其内部流动规律和设计计算方法的研究尚不够深入。1970年西德学者Grabow率先对无叶腔的
Swirl pump (also known as non-clogging pump) due to the special structure (Figure 1), the working principle and the ordinary centrifugal pump is very different. Although this kind of pump has been widely used both at home and abroad, the research on its internal flow law and design calculation method is not deep enough. 1970 West German scholar Grabow pioneered the non-leaf cavity
