These materials are generally used for mechanical seals

These materials are generally used for mechanical seals Mechanical seal is a shaft sealing device that relies on one or several pairs of end faces that slide relative to the shaft perpendicular to the shaft under the action of fluid pressure and the elastic force (or magnetic force) of the compensation mechanism to keep it fit and to be equipped with an auxiliary seal to achieve leakage prevention. Commonly used materials for mechanical seals : 1. Sea water; normal temperature; (dynamic) tungsten carbide, 1CR13 surfacing cobalt chromium tungsten, cast iron; (static) resin graphite, tungsten carbide, cermet; superheated water 100 degrees; (dynamic) tungsten carbide, 1CR13 cobalt surfacing Chromium tungsten, cast iron; (static) impregnated resin graphite, tungsten carbide, cermet. Purified water; normal temperature; (dynamic) 9CR18, 1CR13 surfacing cobalt chromium tungsten, cast iron; (static) impregnated resin graphite, bronze, phenolic plastic, river water (containing sediment); normal...

What factors will affect the service life of mechanical seals?

What factors will affect the service life of mechanical seals ? The main corrosive substance in the desulfurization circulating pump is chloride ions. Due to the strong reducibility of chloride ions, it has corrosive effect on the medium of the mechanical seal material, causing surface corrosion of the mechanical seal. The sealing material medium is limestone and gypsum slurry, the solid content (mass percentage) is about 35%; the temperature is controlled within 70℃; the pressure is less than 0.8MPA; the pH value is between 4-8; the chloride ion content is less than 0.04%. Among them, chloride ions can penetrate mechanical seals when they are severely corroded. What is more serious is that dissimilar metals work together in the medium, causing electrochemical corrosion. This leads to inadequate fixing of the ring. If the sealing surface is in friction for a long time, or the cooling water supply is quickly stopped, or impurities enter the sealing surface, it will initially cause smal...
