在管道弯头内的外侧壁面上布置抗磨肋条 ,观察固相颗粒通过管道时对管壁的磨损 ,比较光滑壁面的弯管和在壁面添加助条的弯管被磨损的情况 ,并初步研究抗磨肋条的优化策略。在 90°弯管的局部范围内布置肋条 ( 10°～ 70°) ,带肋条弯管的减磨效果达 93 .0 2 %。实验结果表明 :在弯管内的外侧壁面上布置抗磨肋条的抗磨策略能明显提高弯管抗磨性能 ;在同一高度下 ,矩形肋条的抗磨效果有比正方形肋条更显著的趋势 ;肋条弯管减磨效果随肋条的数目增多而有变好的趋势
Anti-wear ribs are arranged on the outer wall of the pipe elbow to observe the abrasion of the pipe wall when the solid particles pass through the pipe, the comparatively smooth wall elbows and the elbows on the wall are worn, Anti-wear rib optimization strategy. Ribs (10 ° ~ 70 °) are arranged in a local area of the 90 ° elbow, and the ribbed elbow has an abrasion reducing effect of 93.02%. The experimental results show that the anti-wear strategy of anti-wear ribs on the outer wall surface inside the elbow can obviously improve the anti-wear performance of the elbows. At the same height, the anti-wear effect of the rectangular ribs is more significant than the square ribs. Elbow bend reduction effect with the increase in the number of ribs and have a better trend
