Numerical Investigation on Silt Particle Abrasion Characteristics of the Centrifugal Pump

Abstract

Silt particle abrasion characteristics of the centrifugal pump were numerically investigated. Mean diameter of the employed silt particles was 0.025 mm and the concentration was 1%. Results indicated that for diverse pressure and suction surfaces, distributions of silt particle mass concentration were various. The distribution scope on suction surface was larger than that of the pressure surface. Silt particle abrasion rate on suction surface was greater than in the pressure surface. They were alternation change. The laws on suction surface were contrary to that of pressure surface. The investigations could provide theoretical supports for engineering applications in hydraulic machinery engineering fields.
