Abstract

The present invention relates to one kind of underwater high-confining pressure post-mixing abrasive jet model test system. The model test system consists of mainly underwater environment simulating system and underwater abrasive jet cutting system. The underwater abrasive jet cutting system includes high pressure water generating system, water jet pipeline system, abrasive jet nozzle system, underwater abrasive supplying system and flow rate measuring system. The present invention can realize the underwater cutting environment simulation of any water depth, and solves two difficult problems related to abrasive feeding and back water in underwater high-confining pressure condition. Practice shows that the test system has reasonable design and perfect functions and may be used in the research of abrasive jet erosion performance in any water depth environment.

Description

technical field [0001] The invention relates to an underwater high confining pressure mixed abrasive jet simulation experimental device system, which belongs to water jet [0002] technology field. Background technique: [0003] Internationally, there have been some successful examples of research on submerged abrasive jet technology. In the late 1980s, the University of Hannover in Germany used submerged abrasive jets to conduct cutting tests on steel to find effective parameters of submerged jets. In the early 1990s, researchers from Germany and France used remote control technology to place the abrasive cutting head 15 meters underwater for experiments to verify the cutting control technology, wear status and cutting effect. In November 2000, during the salvage and rescue of the Russian "Kursk" nuclear submarine, it was necessary to drill or cut a hole in the outer walls of different cabins of the nuclear submarine in advance to detect whether there was a nuclear leak in...

AI Technical Summary

Problems solved by technology

However, the change of underwater pressure, the influence of underwater high pressure and the different underwater working environment make the traditional processing method more and more difficult to adapt to underwater working conditions. Therefore, the study of underwater cutting mechanism , Finding new underwater forming tools is an important topic that many researchers are currently facing

However, at present, there is no experimental device capable of simulating the underwater post-mixed abrasive jet cutting environment at any water depth.
