Abrasive water jet theory and research status, proposed hydraulic squeeze-type abrasive water jet system model

Engineered and tested hydraulic squeeze-type abrasive water jet equipment prototypes. Come up with a site can be used for disaster relief, and penetration, crushing various materials (such as steel, steel, concrete, rock, etc.) hydraulic squeeze-type abrasive water jet way and equipment. This paper discusses the abrasive water jet  abrasive grinding  theoretical and research status, proposed hydraulic squeeze-type abrasive water jet system model, and use the theory of transient flow system is analyzed. Hydraulic squeeze-type abrasive waterjet system uses a small horizontal  lycrystalline diamond  abrasive chamber confining pressure from environmental media on the resistance caused by the jet. Environmental conditions at high confining pressure dynamic pressure under the jet axis apparent than in the non-confining pressure decay much faster;
