    摘要:

    按無(wú)過(guò)載離心泵設(shè)計(jì)要求，選擇對(duì)復(fù)合葉輪離心泵性能影響比較關(guān)鍵的葉片出口安放角β2、葉片出口寬度b2、喉部面積Ft和短葉片進(jìn)口直徑Di的4個(gè)參數(shù)為變化因素按正交方案設(shè)計(jì)了9臺(tái)復(fù)合葉輪離心泵模型。采用Fluent全流場(chǎng)數(shù)值模擬方法對(duì)設(shè)計(jì)的9臺(tái)模型泵進(jìn)行正交試驗(yàn)，得到了各幾何參數(shù)對(duì)復(fù)合葉輪離心泵各性能指標(biāo)影響的主次順序， 并得出模型泵的最優(yōu)設(shè)計(jì)方案。對(duì)最優(yōu)設(shè)計(jì)方案的樣機(jī)試驗(yàn)表明，全流場(chǎng)數(shù)值模擬方法的選 優(yōu)結(jié)果在實(shí)現(xiàn)無(wú)過(guò)載的同時(shí)，保持了較高效率，達(dá)到了試驗(yàn)?zāi)康?。研究結(jié)果驗(yàn)證了全流場(chǎng)數(shù) 值模擬正交試驗(yàn)選優(yōu)的可行性。

    Abstract:

    Based on the design requirements of non-overload centrifugal pump, blade outlet angle β2, blade outlet width b2, throat area Ft and the inlet diameter of short blade Di, all of which affects the performance of centrifugal pump with complex impeller were chosen to design nine centrifugal pump models with complex impeller. Numerical simulation of whole flow field based on Fluent was adopted to do orthogonal test, the important order of geometric parameters affect the performance of centrifugal pump with complex impeller. The best design scheme for pump model was acquired. Through the test of specimen of the best design scheme, it demonstrated that the excellent selection by using numerical simulation of whole flow field was non-overload and high efficiency. Orthogonal test based on numerical simulation of whole flow field was verified by the research result.
