Requirements for materials used in mechanical seals

　2017-02-14　　

Any engineering component has certain technical requirements for the materials used. For the materials used in mechanical seals, in addition to general requirements, such as economy, manufacturability, safety and reliability, special requirements different from other mechanical engineering are also put forward; or although the requirements are the same, there are Different significance.

The mechanical seal material should first have impermeability to the sealing medium, and can ensure that the contact gap is filled, and the movement of the mating surface is pressed against the microscopic unevenness to form a friction-resistant pair to ensure the constant sealing contact pressure . Although the technical requirements of the sealing material are of great significance, the key point is to reduce and eliminate the leakage of the medium. First of all, the sealing material can be filled into the gap of the connection. It can be seen that the ideal sealing material Chengdang has structural fluidity, which is similar to liquid fluidity. This is especially important for the modern technology that is constantly increasing in shaft speed and developing towards high-speed machines.　　265.html,
