The non-contact seal of mechanical seal, the manufacturability requirements of materials

　2017-02-14　　

For the non-contact sealing of mechanical seals, the requirements on the manufacturability of materials are quite strict. Generally, the non-contact sealing rotating parts of the dynamic mechanical seal have a complicated shape and significant material consumption. The economy of this type of mechanical seal mainly depends on the degree of high-productivity process methods used in the processing of sealing materials, such as pressure casting, molding, and rolling. The surface roughness of the working foot ring is an important factor. If engineering plastics are used instead of metal materials, due to the relatively high surface roughness, not only the processing hours can be reduced, but the centrifugal sealing efficiency can be increased by 3%-5%. .　　262.html,
