The conflicting vice should ensure a close fit and form a sealing surface to avoid medium leakage. This requires that the pump mechanical seal conflict must have outstanding abrasion resistance; the moving ring can move axially and actively compensate for the wear of the sealing surface, making it fit the static ring outstandingly; the static ring has a buoyancy and cushioning effect.
Elastic components (tension springs, bellows, diaphragms, etc.)
It mainly provides compensation, pre-tightening and buffering effects, and is also an element that causes a reasonable specific pressure on the sealing end face. It is requested that the mechanical seal of the kettle always adhere to the elasticity to overcome the conflict between the auxiliary seal and the transmission parts, and the inertia of the moving ring, etc., and ensure that the end face conflict pair is outstandingly fitted and the moving ring compensation effect.
Auxiliary seals (O-rings, V-rings, wedge-shaped rings, etc.)
It mainly plays a sealing effect on the relative stopper, and also plays a floating and buffering effect. The auxiliary sealing element of the static ring is required to ensure the tightness between the static ring and the gland and the sealing ring has a certain buoyancy; the auxiliary sealing element of the moving ring is required to ensure the seal between the moving ring and the sleeve. The data should have heat and cold resistance and be compatible with the media.
