The application of Bridgman's seal and B-ring seal in the process of pump head auto-frettage

摘要

In this paper,it is described that the seal selected and structure design of plunger hole and liquid export seal in the pump head's experiment of extra-high pressure and auto-frettage. Then,Bridgman's seal and design account for gasket is chose. And liquid export seal used B-ring is chose and analyzed by FEM. The results provide a basis for the experiment about pump head's extra-high pressure and auto-frettage.
