Abstract:

Coal slurry pipeline pressure distribution is related to many factors, and presents the complex nonlinear relationship. The pressure lossmechanism and influence factors of coal slurry pipeline are analyzed in this paper.Considering the coal slurry pipeline pressure loss is combined action of shear stress and frictional resistance, the pressure distribution modelsof the horizontal straight pipe, inclined pipe and vertical pipeline are built respectively.Test results show that the model can accurately calculate the stress distribution of coal slurry pipeline.
