    摘要:

    通過(guò)改變?nèi)~片外緣與殼體之間的間隙,，運(yùn)用CFD軟件對(duì)螺旋離心泵進(jìn)行了內(nèi)流場(chǎng)的數(shù)值計(jì)算,，對(duì)其外特性進(jìn)行了預(yù)測(cè),。并在相應(yīng)條件下通過(guò)螺旋離心泵的性能試驗(yàn)進(jìn)行比較,；研究了間隙變化對(duì)泵性能的影響，給出了間隙的合理范圍,，為螺旋離心泵的設(shè)計(jì)提供了一定的理論和試驗(yàn)依據(jù),，同時(shí)也說(shuō)明了數(shù)值計(jì)算研究方法對(duì)開(kāi)展泵性能預(yù)測(cè)的重要性。

    Abstract:

    The numerical calculation about the interior flow field of the screw centrifugal pump with the CFD software by changing the clearance between the impeller outer edge and shell was given and based on which the exterior performance of the pump was predicted. The performance experiments were done at the same conditions. Compared the performance prediction with the experimental results, the effect of clearance on the pump performance was analyzed and the reasonable range of clearance was given which provided some meaningful references for the design of screw centrifugal pump, and the importance of the numeric simulation method was indicated.
