Abstract
In auto leak detection equipment based on differential pressure decay, plugging quality directly impact on its accuracy and reliability. Since the cylinder is usually used to provide plugging force, plugging cylinder selection is an important part the detection equipment design. The main mechanical structure of the detection equipment was described. The equilibrium equations of plug were established and the bore size calculation formulas were derived in line seal and in face seal. To acquire the parameters such as circumference, area, etc. of the irregular seal surface, the subsection curve fitting-integration method and distilling from CAD model method were studied.
