Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of erosion wear experimental devices, and particularly relates to a novel pneumatic multi-particle continuous ejection experimental system. BACKGROUND

[0002] Erosion wear phenomenon can be seen everywhere in daily life, which is defined as the phenomenon that solid particles mixed in fluid media repeatedly erode the surface of materials at a certain speed and angle to cause material damage and failure. There are engineering applications based on the phenomenon, such as abrasive water jet cutting of plates, and the phenomenon also causes damage to key components of industrial equipment, such as erosion thinning of pipe elbow wall thickness. Erosion wear is a complex process, and many factors affect the process, such as particle incident speed, incident angle, initial azimuth angle, and particle shape and material properties. The coupling between various factors is not conducive to evaluating the specific damage and failure mechanism of the material, so that corresponding improvement measures cannot be proposed. By controlling variables, the repeated erosion behavior of multiple particles under the same or different incident conditions is studied to determine the primary and secondary factors affecting material damage and failure, so as to deeply understand the material removal mechanism and the influence law of particle incident parameters on the material deformation mechanism. Therefore, a novel pneumatic multi-particle continuous ejection experimental system is urgently needed, but there is currently no experimental device that can realize the controllable multi-particle continuous ejection of research variables.
