Types of friction pair materials for mechanical seals:

When selecting mechanical seal materials, the starting point is to ensure that the friction pair materials meet their necessary characteristics as much as possible. In most cases, in order to meet the three major properties of the friction pair material, the general medium often uses a combination of soft and hard friction pair materials. The soft material sealing surface is mainly maintained by the running-in and self-lubricating properties of the wear table. The hard material sealing surface relies on the high precision of the wear table. For the hard-to-hard combination of friction pair materials, it is only used under special circumstances (medium containing hard solid particles). In the following, the friction pair materials are divided into soft materials and hard materials to introduce. 527 mechanical seal 　　994.html,
