Functional requirements for sealing materials of mechanical seals

Mechanical seal sealing data function requirements The function of mechanical seal sealing data is an important factor to ensure a useful seal. The selection of sealing data is mainly based on the operating environment of the sealing element, such as the operating temperature, operating pressure, operating medium used, and movement method Wait. The basic requirements of mechanical seal materials are as follows: 1. The mechanical seal materials have certain mechanical functions, such as tensile strength, elongation, etc.; 2. The elasticity and hardness of the mechanical seal materials are appropriate, and the shrinkage and permanent deformation are small; 3. The mechanical materials are resistant High temperature and low temperature function, no decomposition and softening at high temperature, no hardening at low temperature; 4. The mechanical seal material is compatible with the operating medium, and does not swell, decompose, harden, etc.; 5. The mechanical seal material has good oxygen resistance and aging resistance , Durable; 6. Mechanical seal materials are wear-resistant and do not corrode metals; 7. Mechanical seal materials are easy to form and process, and the price is low; Keywords: mechanical seal
