Research and Development of Mechanical Seal Technology (1)

　2016-12-09　　

Mechanical seal technology abroad, after the 1970s, in order to fundamentally solve the reliability problems of mechanical seal static seals and asbestos substitution problems, a series of international cooperative research has really started, especially the American mechanical engineers A series of experiments on the performance of mechanical seal gaskets organized by the Pressure Vessel Committee (PVRC) under the Association (ASME). Now the series of studies have achieved considerable results, and new design methods and guidelines for mechanical seals have been preliminarily determined.

In the past ten years or so, a lot of work has been done on the research of static mechanical seals in China. Some universities and scientific research institutes have established research institutions and carried out a lot of research and development work. A large number of petrochemical companies using seals It also invested a lot of manpower and material resources. Some seal production plants have been established one after another, and various new sealing materials have been emerging. Now a development system combining scientific research, production and use has been formed, in order to reverse the prevailing situation in the 1970s and 1980s. The phenomena of running, staying, dripping and leaking play a positive role. At present, great progress has been made in product varieties and applications.　　191.html,
