Description

technical field [0001] The invention relates to a mechanical seal controllability test device, which adopts a new structure and a high-precision sensor to measure mechanical seal performance parameters. It belongs to the field of mechanical design and process automation control. Background technique [0002] Since the invention of mechanical seal in 1885, with the deepening of sealing theory and application research, the application fields of mechanical seal have become wider and wider, from petrochemical industry, nuclear industry to aerospace field; the sealing medium has changed from ordinary medium (such as: water) From high-temperature and high-pressure flammable and explosive chemicals, the application has also expanded from water pumps to high-speed and high-pressure gas compressors. [0003] Regarding the research on the sealing mechanism, Dr. E.Mayer from Germany, based on his years of research results—ordinary mechanical seals are generally in the boundary frictio...
