The Hydraulic Institute has just completed the task of developing a new ANSI/HI standard on Rotodynamic (Centrifugal) Slurry Pumps covering nomenclature, definitions, applications, and operation. The standard provides examples of all the different types of pumps available and has an extensive section on definitions. Slurries and their effect on performance and wear are covered. A slurry service...

With the development of coal mining, use elbows has diversified forms underground backfill pipelines, which inevitably complicated transportation characteristics filling slurry in pipeline, thus affecting entire backfilling system. The objective this study is to numerically investigate running state cemented paste (CPB) and coarse particles at different velocities by transporting bend pipes. To...

With the frequent occurrence of geological disasters and extreme weather, pipeline failure accidents secondary caused by debris flow continue to occur. Aiming at impact thin on support pipeline, a multi-physical coupling model with vibration reduction is established based expansion model. The expansive fluid used simulate stress under action flow. results show that effect slurry concentrated in...
