back-up ring的用法详解

'

Back-up rings are one of the components most commonly used in high-pressure hydraulic systems. They are used to reduce the diameter of the seals and provide additional protection for the seals.

Back-up rings are commonly used in combination with O-rings, which are the primary seal in the system. O-rings are installed inside a groove in a mating surface, and the back-up ring helps to further secure the O-ring in place and protect it from wear and tear.

Back-up rings come in two main types: spiral-wound and non-spiral-wound. Spiral-wound back-up rings are made of a coiled steel strip or wire, while non-spiral-wound back-up rings are made of a simply flat strip. Both types of back-up rings are designed to reduce the gap between the O-ring and the mating surface, which further enhances the system’s sealing efficiency.

Back-up rings are not only used in hydraulic systems. They are also used in other applications, including automotive and aerospace applications, where they are used to secure and protect seals and O-rings.

The installation of back-up rings is critical for ensuring the system functions properly. Back-up rings should be installed properly and with the correct amount of tension to ensure the O-rings are held securely in place and protected from damage. When installing back-up rings, it is important to pay attention to the size of the back-up rings and the gap between the O-ring and the mating surface. Too large of a gap can cause the O-rings to slip or fail, while too small of a gap can cause excessive wear and tear on the O-rings over time.
