Abstract: |
Starting from structure, dimension precision and pressure test of break membrane in nozzle closure, the reasons of difficult processing and the low success rate of pressure test are analyzed. The corresponding countermeasure and the clamping and positioning device are designed, and the pressure test equipment is mproved. The machining and test technology of a thin bottom workpiece are obtained according to the verified practice . |
