Guide for Installing Bellow Type Mechanical Seals

The Role of Bellow Type Mechanical Seals

The bellow typr mechanical seal is the sealing component at the connection of the bellows. Its role is to prevent medium leakage and ensure the sealing performance of the bellows system. Therefore, special attention is needed in the selection and installation process of the bellow type mechanical seal.

Installation Method of Bellow Type Mechanical Seal

1. The installation position of the bellow type mechanical seal should be in the groove on the flange side of the bellows flange end face.

2. Before installing the bellow type mechanical seal, the flange end face and seal ring should be cleaned and a certain amount of sealing grease should be applied.

3. With the bellow flange end facing down, align the seal ring with the flange groove and gently push the seal ring in until it rebounds, ensuring the seal ring is fully installed.

4. Finally, tighten the connection bolts of the bellows flange and the flange.

Precautions for Installing Bellow Type Mechanical Seal Rings

• When installing the bellow type mechanical seal, pay attention to the installation direction of the seal ring. Typically, the groove side of the bellows flange is the installation surface of the seal ring.

• The bellow type mechanical seal ring must be installed strictly according to regulations, without omission or duplicate installation.

• When pressing in the bellow type mechanical seal ring, do not exceed the bending limit, otherwise it will cause the seal ring to deform or break.

• The waves of the bellows mechanical seal ring must be closely attached to the flange of the bellows, with no dead angles.

• The bellow type mechanical seal ring cannot be used with other materials to avoid poor material compatibility which can lead to leakage.

By following the above installation methods and precautions, common problems during the installation process of the bellow type mechanical seal ring can be effectively avoided, ensuring the normal operation and service life of the bellows system.

The correct installation and use of bellow type mechanical seal rings are crucial for the performance of the bellows system. It helps to improve the sealing and reliability of the bellows connection, preventing the system from leaking air, oil, etc. Therefore, during use, the correct installation methods and precautions should be followed to ensure the normal operation and service life of the bellows system.
