AI Technical Summary
Technical Problem
特别是在叶片进口段与出口段的过渡区域，流速差异可达30%-40%，导致部分区域因流速过高产生空化侵蚀，部分区域因流速过低造成固体颗粒沉积，既降低了水力效率，提高了循环泵能耗的同时，又加剧了叶片局部磨损
Benefits of technology
[0035]本实用新型提供的一种脱硫浆液循环泵对叶轮进行改进，叶轮的主叶片之间设置若干微导流叶片；脱硫浆液在叶轮流道内通过时，在微导流叶片的辅助下，可使浆液流速均匀，减弱甚至消除因流速过高产生的明显空化侵蚀，以及流速过低造成的颗粒沉积；提高水力效率，降低水力损失，减小循环泵自身的能耗。

Abstract
The utility model discloses a kind of desulfurization slurry circulating pumps, belong to wet flue gas desulfurization equipment technical field;Including:Pump housing;Pump inlet, set in the front of the pump housing, with the pump housing inside intercommunication;Outlet passage, set in one side of the pump housing, with the pump housing inside intercommunication;Motor, set in the back of the pump housing;Impeller, movably set in the pump housing interior;The impeller is rotated under motor drive;Main blade, equidistant distribution in the fluid contact surface side of impeller;Micro guide vane, distribute between the main blade.Micro guide vane is reduced on the basis of chord length and height of main blade in specific proportion, so that the existence of micro guide vane will not cause substantial influence to the flow-through space of slurry between blade, micro guide vane can also improve the speed distribution uniformity of slurry in impeller flow passage, reduce hydraulic loss, reduce energy consumption.
