??Mechanical seals improve analysis solution

??Mechanical rubber seals may be between the sleeve and the shaft, between the ring and the sleeve, between static and dynamic ring seal between the cap and the sealing pump; pump mechanical seal a wide range of leak intuitively difficult to identify and judge shall long-term management, infrastructure maintenance practice, leak symptoms were observed and analyzed, judged, in order to draw the right conclusion. There are four reasons for the failure of the seal rubber seal that is corrosion, heat damage rubber seals, rubber seals wear seals and installation, operation failure caused by such factors.

??Analysis of improving the mechanical seal can be improved in many ways to understand!

??Improving equipment from: the elastic element by a spring to the bellows, the bellows is both elastic member is movable secondary seal ring, eliminating the original rubber seal ring and the sleeve between the seat only in the ring at the end of plus a rubber seal material to seal the premises, it will solve the contradiction between the rubber seal and compensation, but also completely changed the original quasi-static sealing static sealing, improve the reliability of the seal. Bellows also eliminates the need to switch to the mating surfaces of the mechanical seal spring drive pin and ring and ring seat between the ring to avoid action by the deposition of solid particles caused by failure to further improve the overall performance of the mechanical seal . Bellows provides both elastic compensation and provide torque, better follow and ability to compensate.

??During the installation of static trial Improved: After installation and commissioning of mechanical seals, generally the static test, observe leakage. The leak was smaller, more problematic for the ring or static ring rubber seal; leakage is large, then the move, there is a problem of static friction between the deputy. Preliminary observation in the amount of leakage, determine the leaking part, based on the manually jigger observe, if no significant changes in the amount of leakage, the static and dynamic ring rubber seals have a problem; such as disk car leakage significant change, you can conclude it is dynamic and static friction ring problem exists; such as media leaks along the jet axis, the ring seal problems mostly media leaks to the surrounding injection is mostly static ring seal failure. Also, leak paths may exist, but generally the difference between primary and secondary, as long as careful observation, familiar with the structure, will be able to judge correctly.
