The uniformity of graphite has a very important influence on the quality of the production of the sheet, the surrounding gasket and the packing ring. The corrosion type of the graphite sealing material and the corrosion of the protective method mechanical seal
1.1 Metal ring corrosion tops the list, the surface is evenly corroded. If the outer surface of the metal ring touches the corrosive medium, and the metal itself is not resistant to corrosion, surface corrosion will occur, which is leakage, early wear, damage, sound, and the like. The metal surface is uniformly corroded in both film-forming and film-free shapes. The corrosion of the metal without film is very risky, and the corrosion process proceeds at a certain speed, which is mainly caused by the selection of materials. The film is corroded, and its passivation film usually has the property of maintaining the effect. However, the materials used for the metal sealing ring, such as stainless steel, cobalt, chrome alloy, etc., are damaged in the end face friction, and are new under anoxic conditions. The film is difficult to form, making the galvanic corrosion worse.
Second, stress corrosion cracks. Under the effect of corrosion and tensile stress, the metal first cracks in a thin zone, and then develops in the depth, and breaks, called stress corrosion cracking. The hardfacing alloy and cast iron, tungsten carbide, titanium carbide and other sealing rings are used. Simply present stress corrosion cracking. The seal ring cracks are usually radially divergent, so one or more. These cracks communicate the entire sealing end face, accelerating the wear of the end face and adding the amount of leakage.
1.2 Non-metallic ring corrosion tops, graphite ring corrosion. An impervious graphite ring impregnated with resin, which has three causes of corrosion:
First, when the end face is overheated and the temperature is greater than 180oC, the impregnated resin should be folded away from the graphite ring to reduce the wear resistance of the ring;
Second, if the impregnated resin is not properly selected, it will chemically change in the medium and also reduce the wear resistance;
Third, the resin impregnation depth is not good, and when the impregnation layer is removed, the wear resistance is lowered. Therefore, the establishment of the sealed cooling system, the selection of corrosion-resistant impregnating resin, the use of high-pressure impregnation, it is necessary to add the impregnation depth.
