In the petroleum, chemical and other industries, due to the various working media and harsh working conditions of the pump, such as high speed, high pressure, high temperature, strong corrosion, high precision, solid particles, etc.,
when selecting or designing mechanical seals according to the use requirements, in addition to selecting the appropriate sealing structure and sealing system, it is also necessary to pay attention to the materials used for mechanical seals.
It is necessary to correctly select the materials of the sealing pair, auxiliary sealing ring, spring element and other parts according to the specific medium properties and working conditions of the use.
This plays a very important role in ensuring the normal operation of the mechanical seal, extending its service life and reducing costs. The basic requirements of mechanical seal materials are mainly reflected in the material properties.
The performance of the sealing material is an important factor in ensuring effective sealing.
When selecting sealing materials, it is mainly based on the working environment of the sealing element, such as the use temperature, working pressure, applicable working medium and movement mode.
The basic requirements for sealing materials are as follows:
1. Have certain mechanical properties, such as tensile strength, elongation, etc.
2. Appropriate elasticity and hardness, small compression permanent deformation.
3. Resistant to high and low temperatures, no decomposition or softening at high temperatures, no hardening at low temperatures
4. Adaptable to the working medium, no swelling, decomposition, hardening, etc.
5. Good oxidation resistance and aging resistance, durable.
6. Wear-resistant, no corrosion to metals
