O-ring is a kind of seal with annular section, which is used in various industrial equipment. It has sealing function in liquid phase materials with different temperature and working pressure.

Below, Delong Xingye Xiaobian will share with you some advantages of O-ring compared with other sealing rings:
1. The O-ring has the advantages of simple sealing position, compact installation position, relatively small net weight, and good self sealing effect. A hydraulic seal can exceed the actual sealing effect.
2. The O-ring has good sealing performance. When it acts as a fixed sealing performance, there is basically no leakage; And when it acts as a fitness seal, some leakage occurs at high speed. The friction of O-ring aerobics is small and can be integrated into the place where the working pressure changes.
3. O-ring standardization and pipe trench standardization have the advantages of low cost, simple product, convenient use and convenient carrying of outsourced products. Compared with other sealing rings, O-rings are also the following three problems, with special attention:
① The friction resistance of O-ring during startup is large.
② When the O-ring is used as the sealing property of pneumatic equipment, it is necessary to add grease to avoid damage.
③ O-rings have strict regulations on the production and processing of connectors, such as fitness venues, pipe ditches, open spaces, etc
The storage method of O-ring is as follows: pay attention to the deformation of O-ring when installing O-ring in pipe trench. When installing the O-ring, the O-ring of the pipe trench shall be coated with sealing material. When not in use, do not open the original packaging of the O-ring, so as to prevent the dust on the O-ring from entering the dirt and causing the danger of the O-ring. Cut off sunlight and place it around high-temperature heat sources such as heating furnace to prevent O-ring embrittlement, avoid hanging on the metal wire of the needle, and prevent O-ring deformation and lip damage.
It should be noted that the O-ring will sometimes fade during storage, and white frost will form on the surface of the O-ring, which will have a negative impact on the effect of the O-ring.
