O-ring is a commonly used sealing element, made of materials such as rubber or plastic, with good sealing performance and wear resistance. Its cross-section is circular, so it is called O-ring. O-ring is widely used in machinery, automobile, aviation, aerospace and other fields, and is an indispensable sealing element.
The main function of O-ring is to form a seal between two joint parts to prevent liquid or gas leakage. It can withstand harsh environments such as high pressure, high temperature and chemical corrosion, and has good durability and stability. The sealing performance of O-ring depends on the selection of its material and manufacturing process. Generally speaking, materials such as silicone rubber, fluororubber, nitrile rubber have good heat resistance and corrosion resistance, and different hardness and thickness can be selected according to different application scenarios.
O-ring is widely used in mechanical seals, automobile engines, tires, hydraulic systems, pneumatic systems, aerospace and other fields. For example, in mechanical seals, O-rings are usually used in shaft seals, oil seals, water seals and other positions to ensure the stable operation of mechanical equipment. In automobile engines, O-rings are used to seal cylinder heads, crankcases, oil pans and other parts to prevent oil leakage. In hydraulic and pneumatic systems, O-rings are used to seal oil cylinders, air cylinders and other parts to ensure the normal operation of the system.
In short, O-rings are a kind of sealing element widely used in various fields. They have good sealing performance, wear resistance and durability, and are an indispensable mechanical element.
