US3601413A - Mechanical seal - Google Patents
A mechanical seal includes a sealing surface formed by chemical vapor deposition of an extremely hard material, such as silicon carbide. The surface is finished to the required smoothness by optical grinding. The resulting seal has excellent wear resistance as well as high tolerance to corrosive chemicals, extreme temperatures and other adverse operating conditions.
5 Ways To Kill A Mechanical Seal During Installation
4. Dirty work surface/hands. Dirt on the seal face, even oil from finger prints, can set a mechanical seal up to fail. Tiny particles can create wear and destroy seal faces, causing leakage. Ensure proper handling during installation by following these tips: 5. Uneven or over-tightening of fasteners.
