Mechanical seal sealing material performance requirements

Mechanical seal sealing material performance requirements The performance of the mechanical seal sealing material is an important factor to ensure effective sealing. The choice of sealing material, the main mechanical seal should be based on the working environment of the sealing element, such as the use temperature, the working pressure, and the working medium used. Mechanical seals and movement methods, etc. The basic requirements of mechanical seal materials are as follows: 1. The mechanical seal material has certain mechanical properties, such as tensile strength, elongation, etc.; 2. The mechanical seal material has proper elasticity and hardness, and has small compression set; 3. The mechanical material has resistance High temperature and low temperature performance, no decomposition and softening at high temperature, and no hardening at low temperature; 4. The mechanical seal material is compatible with the working 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 are low in price; Keywords: mechanical seals, mechanical seals
