| Abstract: | The basic principle, accuracy and resolution of the leak detection method by means of bubble emission were investigated, and the calculating formula of leakage rates was derived. The leakage rates of rubber asbestos gaskets were measured with this method. The experimental data possess a good comparability with which obtained with the leak detection method by measuring the pressure increment in a sealing capsule. The matters needing attention for using the leak detection method in practice are also discussed in this paper. |
