Method And Theory About Defect Detection Of Empty Tube Detonators Made In Metal

This paper which uses non-destructive testing technology and CFD (Computational Fluid Dynamics) theory were a complete three-dimensional analysis of high-pressure air tube gas detection detonators, and were simulated leak at different locations,comparison of changes in its parameters .It is use in the production and save resources play a human role. This article is composed of five.(1)Defects and the harm of empty tube detonators are introduced in the production process and made a detailed description of detection technology. It determined program of high-pressure gas detection.(2)Introduce the equation, turbulent energy equation and the equation of state about numerical analysis of High-pressure air detection empty tube detonators based on the principle of fluid dynamics.(3)It establish a three-dimensional model of high-pressure gas detection empty tube detonators use Pro/e,which mesh grid and set the boundary conditions of model in Gambit . Numerical simulations of three-dimensional and two-dimensional have been made. ( 4) Three-dimensional model of automatic detection system of empty tube detonators was established in Pro/e and made a detailed description that empty tube detonators have sport in each movement of the system and structure of system.(5)This article summarizes the work.
