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
