The mechanical seal is a device used to solve the sealing between the torsion shaft and the machine body. The mechanical seal is composed of at least one pair of end faces perpendicular to the torsion axis. Under the cooperation of the fluid pressure and the elastic force (or magnetic force) of the compensation mechanism and the auxiliary seal, it is connected and fitted and relatively sliding to prevent fluid leakage. It is often used in pumps, compressors, etc. Machines, reaction pumps, mechanical seals, stirring tanks and other torsional fluid machinery, and also used for sealing of gearboxes, valves, torsional joints, and ship stern shafts.

Skeleton oil seal is a typical representative of oil seal, generally speaking, oil seal refers to skeleton oil seal. The advantage of the oil seal is generally to isolate the parts that need to be lubricated from the output parts in the mechanical seal transmission parts for the kettle, so as not to let the lubricating oil leak. The skeleton is like the steel bar in the concrete member, which has the benefit of strengthening and enables the oil seal to maintain its shape and tension. According to the structure, it can be divided into single-lip skeleton oil seal and double-lip skeleton oil seal. The auxiliary lip of the double-lip skeleton oil seal has the advantage of dust prevention, preventing external dust and impurities from entering the machine. According to the frame type, it can be divided into inner frame oil seal, exposed frame oil seal and assembled oil seal. According to the working conditions, it can be divided into torsion skeleton oil seal and reciprocating skeleton oil seal. Widely used in gasoline engine crankshafts, diesel engine crankshafts, gearboxes, differentials, shock absorbers, engines, axles and other parts. There are two types of gaskets. Static seal and dynamic seal.
