摘要 离心泵的运行工况低于设计工况时,效率降低,耗能增加。为了优化离心泵运行工况的调节,运用叶轮机械设计和前置导叶预旋调节的基本理论,在整流片和Gottingen-364翼型的基础上,设计出两种不同翼型的前置导叶预旋调节装置,研究了不同翼型前置导叶正预旋对离心泵水力特性的影响。试验结果表明,对于单吸离心泵:适当的前置导叶正预旋调节角度选择能够达到离心泵增效节能的效果。与无导叶工况相比,等厚直叶片使离心泵效率最大提高2.05%,功率消耗最多节省6.35%;Gottingen弯叶片使离心泵效率最大提高2.34%,功率消耗最多节省6.53%;两者都减小了扬程,但影响程度较小。等厚直叶片在两个预旋角度下最高效率点都往小流量区偏移到Q=172 m3/h处;对于Gottingen弯叶片,20°预旋时,最高效率点往小流量区偏移到Q=172 m3/h,40°预旋时,最高效率点往小流量区偏移到Q=190 m3/h,两个预旋角度高效区都得到了扩大。

Abstract: When centrifugal pump runs deviated from the design condition, it will increase energy consumption but reduce the efficiency. To optimize the running condition, according to the basic theory of turbomachinery design and inlet guide vanes prewhirl regulation, two different airfoils inlet guide vanes of prewhirl device were designed. Positive prewhirl guide vanes with different airfoils have been studied to determine their hydrodynamic effect on centrifugal pumps. The result shows a single-suction centrifugal pump, appropriate design of positive prewhirl could increase the efficiency of centrifugal pumps. Compared with the performance of the centrifugal pump without inlet guide vane, the efficiency of straight blade-type centrifugal pump could mostly increase 2.05% and the reduction in power consumption could reach the maximum of 6.35%. For Gottingen bowed blade-type, the efficiency of centrifugal pump could mostly increase 2.34% and the reduction in power con-sumption could reach the maximum of 6.53%. Both types have little influence on the head. For straight blade-type, the best efficiency point changed then obtained at Q=172 m3/h. For Gottingen bowed blade-type with 20° prewhirl, the best efficiency point changed then obtained at Q=172 m3/h. Besides the best efficiency point will obtained at Q=190 m3/h when its prewhirl was 40°. The high efficiency scopes of both prewhirl were extended.
