The reasons for the poor or failure of the sealing effect of graphite sealing components may vary, but here are some common ones:
1.Insufficient Surface Roughness: If the surface roughness of the graphite sealing component is insufficient, it may lead to incomplete contact between sealing surfaces, thereby reducing the sealing effect. This may result from processing issues or wear during manufacturing.
2.Improper Material Selection: The chosen graphite material may not be suitable for the specific working environment or medium. Certain media may cause corrosion or chemical changes in graphite, affecting its sealing performance.
3.Improper Installation: If the graphite sealing component is not properly fastened or positioned during installation, it may deform or distort, thereby affecting the sealing effect.
4.Inappropriate Temperature and Pressure Conditions: The performance of graphite sealing components is often influenced by temperature and pressure. If the temperature or pressure in the working environment exceeds the design range of the graphite sealing component, it may lead to poor sealing or failure.
5.Aging and Wear: Long-term use or improper operation may lead to aging and wear of graphite sealing components, reducing their sealing performance. This may include surface wear, cracking, or deformation issues.
6.Special Properties of the Medium: Some media may have special chemical properties or viscosity that could adversely affect the performance of graphite sealing components, such as the flowability, acidity or alkalinity, or solid particle content of the medium.
In summary, the poor or failure of the sealing effect of graphite sealing components may result from a combination of factors. Therefore, when selecting, installing, and using graphite sealing components, it is necessary to consider various factors comprehensively and ensure compliance with design requirements and working conditions.
