jailcd2020065: Research Progress on Resistance Loss of Slurry Pipeline Transportation

Abstract

As pipeline transportation can not only save a lot of manpower and material resources, but also reduce transportation costs, save time and protect the environment, the pipeline transportation technology is widely used in industrial fields such as metallurgy, gas, coal mines, chemical engineering, water conservancy and environment protection, which is important Practical significance. The resistance loss is a major factor affecting the efficiency of slurry pipeline transportation. As one of the core contents of pipeline engineering design, the study of pipeline resistance loss is of great significance. This paper mainly discusses the generation mechanism of frictional resistance, particle collision resistance and particle sedimentation resistance loss in pipeline transportation introduces the basic theory of pipeline transportation resistance loss, including diffusion theory, gravity theory and energy theory, and lists the four most common ones The calculation model of pipeline transportation resistance loss provides basic data for further research on slurry pipeline transportation.
