Features and application scope of O-ring

The O-ring is composed of a low friction filled polytetrafluoroethylene (PTFE) ring and an O-ring. The O-ring provides sufficient sealing preload and compensates for the wear of the PTFE ring. The friction coefficient of PTFE is small and the dynamic and static friction coefficients are similar. The O-ring is composed of a low friction filled polytetrafluoroethylene (PTFE) ring and an O-ring. The O-ring provides sufficient sealing preload and compensates for the wear of the PTFE ring. The friction coefficient of PTFE is small and the dynamic and static friction coefficients are similar. It is suitable for high and low speed reciprocating motion and high pressure system. Two step rings are used for sealing, and zero leakage can be achieved. 1. Features of O-type rubber seal ring: 1. Easy to install. Because the structure of O-type rubber seal ring and its installation parts are extremely simple and standardized, it is very easy to install and replace. 2. The structure is simple and the sealing performance is good. The section structure of O-type rubber seal ring is extremely simple. It has self sealing function and reliable sealing performance. 3. It can be widely used to effectively seal oil, water, air, gas and various chemical media by selecting appropriate rubber materials and designing appropriate formula. The temperature can be used in a wide range of - 60 ℃ ~ + 220 ℃), and the pressure can reach 1500kg / cm2 when it is fixed (used in combination with the reinforcing ring). 4. There are various kinds of materials suitable for various purposes, and the sizes and grooves have been standardized. 2. Application scope of O-type rubber seal ring: the O-type rubber seal ring is widely used in the sealing of diesel locomotive, automobile, tractor, engineering machinery, machine tool and various hydraulic and pneumatic components. It can bear the sealing of fixed, reciprocating and rotary motion. The O-type rubber seal ring accounts for more than 50% of the sealing of mechanical products. According to the need, it can produce all kinds of special-purpose sealing rings and special-shaped rubber sealing products for high temperature, low temperature vacuum, high pressure and different media.
