China OEM Oil Seal 90311-50037 - Mechanical Spring Seal 3.75″RTG22 SIC/SIC/FKM – GS Seal

Mechanical seal type MG1 109-100 ASF G9

Mechanical seal refers to at least a pair of end faces perpendicular to the axis of rotation under the action of fluid pressure and compensation mechanism elastic (or magnetic force) and with the cooperation of the auxiliary seal to keep fit and relatively sliding device to prevent fluid leakage.

The elastic loading mechanism with the auxiliary seal is the mechanical seal of the metal bellows which we call the metal bellows seal.In the light seal, and the use of rubber bellows as auxiliary seal, rubber bellows elastic limited, generally need to be supplemented by spring to meet the loading elastic.”Mechanical seal” is usually referred to as “machine seal”.

Mechanical seal is a shaft seal device of rotating machinery.Such as centrifugal pumps, centrifuges, reactors and compressors and other equipment.Because the drive shaft runs through the inside and outside of the equipment, there is a circumferential clearance between the shaft and the equipment, and the medium in the equipment leaks outward through the clearance. If the pressure in the equipment is lower than atmospheric pressure, the air leaks into the equipment, so there must be a shaft seal device to stop the leakage.There are many kinds of shaft seals. Because the mechanical seal has the advantages of less leakage and long life, the mechanical seal is the most important shaft seal in these equipment in the world.Mechanical seal is also called the end face seal, in the relevant national standards is defined in this way: “by at least a pair of perpendicular to the axis of rotation of the end face in the fluid pressure and compensation mechanism elastic (or magnetic force) role and auxiliary seal with the combination of the relative slide and maintain stick to prevent fluid leakage device
