Problems solved by technology

Therefore, the failure mechanism of pipeline erosion wear has always been the focus of research by scholars at home and abroad. The indoor experimental characterization of phase erosion is more difficult than that of two-phase erosion. Most of the existing erosion experimental devices rarely consider the influence of temperature on material erosion, the erosion angle can be adjusted, and the erosion experiment can be visualized. The erosion test device can only realize jet erosion or pipe flow erosion alone, and no erosion test device can complete jet flow erosion and pipe flow erosion at the same time

Description

technical field [0001] The invention relates to a gas-liquid-solid erosion wear experiment device combining multi-parameter adjustable jet flow and pipe flow and a use method thereof, belonging to the technical field of parts surface erosion experiment. Background technique [0002] Erosion is a phenomenon in which fluid and fluid-carrying phases (such as droplets, sand, cuttings and other particles) hit the material surface (target surface) at a certain angle and speed, resulting in deformation of the target surface and material loss. Erosion wear is widespread in petroleum, chemical, hydropower and other industrial processes. Various types of equipment exposed to moving fluids will be damaged by erosion wear, which is an important cause of equipment failure. Therefore, the failure mechanism of pipeline erosion wear has always been the research focus of scholars at home and abroad. Scholars from all over the world have proposed their own erosion experimental devices. Among ...
