Professional Testing Method of Oil Seal Performance

图片
Automotive oil seal ,  commonly known as valve oil seal, is one of the rotary seals. It has good elasticity, low compression deformation and aging resistance, but the rubber seal material must be adapted to the working conditions of the car, the type of medium, working pressure, temperature and application status and other conditions. Automotive oil seals prevent oil from entering the intake and exhaust pipes, causing oil loss, preventing gasoline and air mixture and emission exhaust gas leakage , and preventing engine oil from entering the combustion chamber. The valve oil seal is one of the important parts of the engine valve set, which is in contact with gasoline and oil at high temperature, so it needs to be made of materials with excellent heat resistance and oil resistance, usually fluoroelastomer. In addition to fluoroelastomer, NBR, silicone rubber, acrylate rubber, polyurethane and PTFE are also commonly used materials. The representative form of oil seal is  TC oil seal ,  wh

What Is the Function of Skeleton Oil Seal

The role of the  skeleton oil seal  is generally to isolate the parts that need lubrication in the transmission parts from the output parts so as not to leak the lubricant.   Rotary shaft, a rotary shaft lip seal. The skeleton is just like the reinforcing steel inside the concrete structure, which plays a reinforcing role and allows the oil seal to maintain its shape and tension. According to the skeleton type, it can be divided into inner skeleton oil seal, outer skeleton oil seal, and inner and outer skeleton oil seal. The skeleton oil seal is made of high-quality nitrile rubber and steel plate, with stable quality and long service life. Widely used in automobiles, motorcycle crankshafts, camshafts, differentials, shock absorbers, engines, axles, front and rear wheels and other parts.   1. Prevent sediment, dust, moisture, etc. from invading the bearing from the outside;   2. Limit the leakage of oil in the bearing. The requirements for oil seals are that the dimensions (inside diame
