Oil seal engine: Introduction to oil seal technology and DigiPlus fair valueits application in engine Engine is one of the core components of modern automobiles and one of the most active mechanical parts. It contains many mechanical parts and systems, among which oil seal technology is an important part of engine operation. The oil seal technology aims to prevent lubricating oil from leaking out of the engine, while preventing external dust and particles from entering the engine, so as to ensure the normal operation of the engine. In the development of the automobile manufacturing industry, oil seal technology has been widely applied and developed.The function of engine oil seal. In order to maintain sufficient gaps between parts to prevent wear and overheating caused by thermal expansion, lubricating oil must be used for lubrication and cooling. The oil seal technology on the engine aims to prevent lubricating oil from leaking from the engine and reduce pollution to the atmospheric environment as much as possible. In addition, the oil seal can also reduce the friction and noise generated by the engine and improve the life of the engine. Types of engine oil seals Engine oil seals generally include several types: shaft seals, hydraulic seals, gas seals and flange seals, etc. Different types of oil seals need to have different sealing effects, structural forms and wear resistance. Shaft seal: The main function of the shaft seal is to make the bearing of the turning shaft cover the oil seal, so as to protect the engine from the entry of external dust, particles and other impurities. The material of the shaft seal needs to have good wear resistance, high temperature resistance and oil resistance.Hydraulic seal: Hydraulic seal is an encapsulation material used to isolate hydraulic components from the outside world. This packaging material is usually made of rubber, nylon and coating materials to ensure hydraulic balance and prevent oil leakage. The sealing performance of the hydraulic seal is very important for the operation of the engine. Gas seal: The gas seal is mainly used in the combustion chamber of the engine to ensure the normal operation of the engine. The materials used to make this seal are usually high-temperature, wear-resistant and corrosion-resistant metal materials, such as stainless steel and titanium alloy. It has good sealing, heat conduction and corrosion resistance. Flange seal: Flange seal is a kind of packaging part with flange and sealing material as the main structure, which is widely used in automobile cooling and hydraulic systems. For example, the flange seal in the car radiator needs to be high-temperature resistant, wear-resistant and corrosion-resistant to avoid water leakage and pollution of the engine.The development trend of engine oil seal At present, with the continuous progress of science and technology, the oil seal technology of automobile engines has been greatly improved, and new oil seal materials are constantly emerging. These new materials can better protect the lubrication system of the engine to extend the service life of the engine. Among them, new materials such as polytetrafluoroethylene, butadiene rubber, ternary ethylene propylene rubber, silicone rubber, etc., have the characteristics of waterproof, oil-proof, corrosion-resistant and wear-resistant, and have been widely used in engine seals. In addition to new materials, the manufacturing process of engine oil seal technology is also constantly improving. For example, the production method of chemical evaporation can not only reduce the production time, but also improve the quality of the seal. Compared with traditional mechanical manufacturing methods, the manufacturing process of chemical evaporation has superior performance and reliability, and is more and more widely used in oil seal manufacturing.In a word, the development of engine oil seal technology is still constantly progressing and upgrading. The emergence of new materials and processes will certainly bring more innovations and breakthroughs to oil sealing technology. In the future, the automobile industry will continue to improve the requirements for oil seal materials and oil seal technology, and apply more advanced technologies and materials to make the performance and life of the engine reach a higher level.
