    摘要:

    采用徑向前置導(dǎo)葉實(shí)現(xiàn)預(yù)旋，將葉輪與前置導(dǎo)葉結(jié)合進(jìn)行研究，推導(dǎo)了有預(yù)旋離心泵的最大軸功率及其對(duì)應(yīng)流量的計(jì)算公式。分析了導(dǎo)葉幾何參數(shù)對(duì)泵理論揚(yáng)程曲線、功率曲線、理論最大流量、最大軸功率及最大軸功率對(duì)應(yīng)流量的影響。利用CFD軟件對(duì)幾何參數(shù)不同的8組方案進(jìn)行數(shù)值模擬，將模擬結(jié)果與公式計(jì)算結(jié)果進(jìn)行對(duì)比。驗(yàn)證了公式的正確性，該公式對(duì)無(wú)過(guò)載離心泵設(shè)計(jì)具有指導(dǎo)作用。

    Abstract:

    Both the impeller and inlet guided vanes were studied. Considering the inlet prewhirl by using radial inlet guided vanes, the calculation formula of the pump’s maximum shaft power and its corresponding flow rate were deduced. The effects of inlet guided vanes’ geometric parameters on theoretical head curves, power curves, theoretical maximum flow rate, maximum shaft power and its corresponding flow rate were also analyzed. Then eight schemes with different geometric parameters were numerically simulated by using CFD software, the validity of the formula was verified by comparing numerical result and formula calculation, indicating that it can provide guidance for the design of non-overload centrifugal pump.
