*Related Introduction*
When designing a mechanical seal for a pump, not only the influencing factors of the mechanical seal itself, but also various influencing factors outside the mechanical seal must be considered. Pay attention to the following issues in actual work:
(1) In the design process of pump products, full consideration should be given to the influence of other pump parts and other equipment on the use effect of the mechanical seal, so as to create a good external condition for the mechanical seal.
(2) Increase the understanding of the important role of the mechanical seal auxiliary system, and equip it with a complete mechanical seal auxiliary system as much as possible to improve the sealing effect.
(3) For the mechanical seals of important pump products, protective measures should be added to improve seal quality and reduce seal quality accidents.
(4) When analyzing the causes of mechanical seal quality accidents, it is necessary to fully consider the impact of other parts of the pump on the operation of the mechanical seal, and take measures to continuously improve the effect of the mechanical seal.
