tätningsring

A tätningsring, also known as a packing ring or packing, is a mechanical seal used to prevent the leakage of fluids or gases in rotating shafts. It is typically made from materials such as graphite, PTFE (polytetrafluoroethylene), or other suitable sealants. The tätningsring is designed to create a tight seal between two mating surfaces, often in applications where a dynamic seal is required, such as in pumps, compressors, and other rotating machinery.

The tätningsring is installed in a groove or annulus around the shaft, and it is compressed by a gland or other means to ensure a proper fit. The design of the tätningsring can vary depending on the specific application and the type of fluid or gas being sealed. For example, in high-pressure applications, a multi-piece tätningsring may be used to distribute the load more evenly and reduce the risk of failure.

Proper installation and maintenance of the tätningsring are crucial for its effectiveness. Regular inspection and replacement of worn or damaged tätningsrings can help prevent leaks and ensure the reliable operation of the machinery. Additionally, the choice of tätningsring material should be compatible with the fluid or gas being sealed to avoid chemical reactions that could degrade the seal or the machinery itself.
