The current progress of domestic mechanical seal technology

　2016-12-29　　

At present, domestic flange gaskets use the old ASME code m, y coefficient method, but the sealing parameters m and y values u200bu200badopted by the ASME code are unreliable, and the sealing design method and gasket sealing performance test method themselves have certain The limitations. my country has also done a lot of work in this area. Domestic research units, especially colleges and universities, have conducted a lot of experimental research and have achieved gratifying results. For example, the research on flange gasket sealing parameters and new structure undertaken by the University of Petroleum, and its room temperature gasket sealing test equipment, including the computer data acquisition and control system, is close to the international advanced level. The sealing design methods, test methods and tightness criteria proposed in China have been developed to the practical stage.　　217.html,
