| Abstract: | Some abrasive would effuse from the abrasive tank after stopping the power in DIAJET.And the abrasive led much abrasion on the elements, especially on the nozzle.The analysis was carried out on the primitive DIAJET system.And based on the analysis result, three type of improved structure were put forward for the effused abrasive and abrasion problem.Qualitative analysis in theory were done for the improved structure.The velocity of high pressure gluey pipeline was obtained by experiment method.After analysis and contrast by experiments,the first type improved DIAJET structure is thought as the best one.It can deal with the above problem by decreasing the volume of effused abrasive greatly.6figs.,2tabs.,6refs. |
