*Related Introduction*

The sealing surface of the mechanical seal must have a certain specific pressure in order to achieve a sealing effect. This requires a certain amount of compression of the spring of the mechanical seal to give a thrust to the sealing end surface, and rotate to make the sealing surface produce the required ratio of the seal. Pressure. In order to ensure this specific pressure, the mechanical seal requires the pump shaft not to have too much displacement, generally within 0.5 mm. However, in the actual design, due to the unreasonable design, the pump shaft often produces a large amount of displacement, which is very unfavorable to the use of the mechanical seal. This phenomenon often occurs in multi-stage centrifugal pumps, especially when the pump is started, the amount of channeling is relatively large.
