渣浆泵叶片出口边无叶空间内流动分析与凹度计算

Flow Analysis within Vaneless Cavity and Concavity Calculation of Vane Exit Edge for Slurry

通过对渣浆泵转轮的凹形叶片出口边的研究,从流体动力学的角度指出了改善渣浆泵过流部件磨损情况的可能性;提出的计算凹度的半经验公式,经过实践考验证明具有一定的实用价值。

After investigating the concave exit edge of slurry pump impeller, the paper points out the possibility to improve the flow passage wear of slurry pumps in the hydrodynamics point of view. Experimental investigations show that the semiempirical concavity calculation formulation given here are practical.
