Taiwan specializing in the supply of imported seal top Wall TC model seal, TC oil seal, high temperature seals, nitrile seals, fluorine rubber seals, and so on. Seal oil seal is a typical representative of, the general said, referring to the oil seal oil seal. The role of oil seals in general is part of the drive components need lubrication and output components isolation, and will not allow oil leakage. Like skeleton reinforced concrete structures inside, serve to strengthen the role and seal to maintain the shape and tension. Form of the structure can be divided into single-lip oil seal and oil seal lips. Vice-lip oil seal lips played the role of dust, to prevent outside dust and impurities into the inside of the machine. Skeleton type can be divided according to package seal, and seal the exposed skeleton oil seal assembly. According to the working conditions can be divided into rotating and reciprocating oil seal oil seal. For gasoline engine crankshaft, diesel engine crankshaft, transmission, differentials, shock absorbers, engines, axles and other parts. Skeleton oil seal structure: seal structure consists of three parts: seal body, strengthen the skeleton and the self-tightening spiral spring. Sealing body is divided into different parts according to bottom, waist, edge and sealing lip and so on. In general, oil seal a free state, the inner diameter smaller than the shaft, which has a certain "amount of interference." Thus, when the seal into the seal seat and shaft seal edge pressure and self-contraction of the tight coil spring shaft produce certain radial clamping force, after a period of time to run, the pressure will decrease rapidly and even disappear thus, you can always compensate plus spring force from the tight seal. Imported oil seal TC model application: Widely used in aviation, automobile, motorcycle, railway, vehicles, ships, home appliances, construction machinery and other industries. Adapted for rotary motion and reciprocating seals. Installed in various heavy model engines, transmissions, axles, ships, cylinders and other parts. Primarily prevents the sealing medium (gas liquid.) Penetration and foreign matter into the body. Note TC oil seal: the common seal pressure range is very limited, typically 0.03 MPa. This pressure is generally lubricating oil pressure elevation formation itself. If you need to seal a higher pressure, the need to use high-pressure seals (generally can withstand up to 1 MPa pressure) or use other forms of sealing.
