    摘要:

    為解決國(guó)產(chǎn)標(biāo)準(zhǔn)泵蝸殼壁較厚問(wèn)題,，用傳統(tǒng)公式計(jì)算S50-160/75型標(biāo)準(zhǔn)泵壁厚,，并進(jìn)行修正,。采用Fluent模擬小流量與設(shè)計(jì)工況下蝸殼內(nèi)沿液流方向的壓力分布,，分別為由大到小再變大及逐漸增大的趨勢(shì)。采用ANSYS計(jì)算2種工況下蝸殼所受應(yīng)力與應(yīng)變情況,，得到易破壞部位分別為蝸殼隔舌與環(huán)形部分最大尺寸軸面處,。對(duì)蝸殼強(qiáng)度進(jìn)行校核及有限元分析，表明修正后的蝸殼壁厚滿足強(qiáng)度要求,。并通過(guò)水力性能試驗(yàn),，得到計(jì)算結(jié)果與試驗(yàn)數(shù)據(jù)相吻合。

    Abstract:

    The thickness of the S50-160/75 standard pump volute calculated by the traditional formula was amended to solve the volute wall of the domestic standard pump. The pressure distributions in the volute along the flowing were simulated by using Fluent software, and the trends were from rising to declining to rising again in low flux condition and rising gradually in rated condition. The stresses and strains have been calculated approximately in different conditions with ANSYS software, it concluded that the throat section and the largest ring of the axial region are the most easily damaged and the most dangerous parts. Strength check on the volute and finite element analysis showed that the amended thickness of the volute met the strength requirements. And the hydraulic performance tests of the pump proved that the calculated results are consistent with the actual results.
