Failure and treatment of mechanical seal of reactor


Failure and treatment of mechanical seal parts


Fault causes and phenomena






During the operation of the reactor, the sealing end face often appears wear, hot crack, deformation, damage and other situations, and the screw, thread, spring will also relax, fracture and corrosion after being used for a long time. The auxiliary seal ring will also have cracks, twists and deformation, cracks and other situations.








Troubleshooting






If the parts of the mechanical seal fail, it is necessary to replace the parts or improve the machining accuracy of the parts. Improving the machining accuracy of the mechanical seal itself and other parts of the reactor is very beneficial to the effect of the mechanical seal.






In order to improve the sealing effect, the requirements for the smoothness and flatness of the friction surface of the moving ring and the static ring are higher. The width of the friction surface of the moving ring and the static ring is not large, generally between 2-7 mm.
