摘要：
In order to improve the safety of pipeline transportation, model pumps with different inlet angles and blade quantities were designed and the pipeline transportation system was built. The particles with volume fraction of 5% and diameter of 3 mm were transported to different model pumps. Based on the results, the influence of the design parameters of the guide blade on the particle passing the pump was analyzed. The results show that the pump is better when the inlet angle is 25° and when there are 5 blades. In this model pump, the particles enter the passageway from the back of the guide leaf, and it is not obvious that the particle impacts the back of guide vane. Particles flow out of the guide vane from the center of the passageway, potentially reducing the impact. The particles have less time to pass through this pump than other pumps, and particles do not all collide in one single place, which leads to less wear for the guide vane. © 2018, Central South University Press.
