Mechanical seals are precision, structurally complex basic mechanical components and are key parts of various pumps, reaction and synthesis vessels, turbo compressors, submersible motors, and other equipment. A mechanical seal mainly consists of two parts: a rotating part (carrying the rotating ring) and a stationary part (carrying the stationary ring). The mating end faces of the rotating and stationary rings form the main sealing surface (friction pair). The materials used for mechanical seals are selected according to the medium. Common materials for the friction pair (rotating/stationary ring) include silicon carbide, cemented carbide (tungsten carbide), ceramics, and resin-impregnated graphite. Common materials for auxiliary seals (O-rings, etc.) include nitrile rubber, fluororubber, silicone rubber, polytetrafluoroethylene (PTFE), and expanded graphite. The main selection parameters are: seal chamber pressure (MPa), fluid temperature (°C), operating speed (m/s), fluid characteristics, and the effective space available for seal installation.
