The main reasons for failure of mechanical seals due to improper selection of materials include improper matching of sealing surface materials, poor pressure resistance, poor corrosion resistance and poor vibration resistance.
Detailed explanation Improper matching of sealing surface materials: If the selection of sealing surface materials is not appropriate, it will lead to poor sealing effect and easy leakage. For example, some materials will deform or harden under high temperature or high pressure environment, resulting in sealing failure.
Poor pressure resistance: Mechanical seals need to withstand a certain pressure to work properly. If the pressure resistance of the material is insufficient, the sealing surface will deform or crack under high pressure, resulting in leakage.
Poor corrosion resistance: Corrosion is one of the common reasons for failure of mechanical seals. If the material is not corrosion-resistant, it will gradually be eroded after contact with the medium, resulting in damage to the sealing surface.
Poor vibration resistance: Mechanical seals will be affected by vibration during operation. If the material is not vibration-resistant, the sealing surface will loosen or be damaged during vibration, resulting in leakage.
By selecting suitable materials and optimizing the design, these failure problems can be effectively avoided to ensure the stability and reliability of mechanical seals.
