        The advantages and disadvantages of metal bellows mechanical seal

        The advantages of metal bellows mechanical seal:

        1. The force on the sealing end face of the bellows mechanical seal is relatively uniform;

        2. Simple structure, easy installation, strong adaptability, static ring with floating.

        3. The bellows mechanical seal has good followability, which can make up for the end clearance (generally less than 1μm) caused by the bending deformation of the rotating shaft, the vibration of the equipment, the coaxiality error of the static and static ring and the sleeve to a certain extent, so as to reduce the leakage of the mechanical seal;

        4. The static ring of the bellows mechanical seal is fastened on the mechanical seal gland by bolts.The static ring of most spring type mechanical seals basically relies on the over-matching of the O-ring with the mechanical seal gland, as well as the action of the fluid pressure and the external spring to seal. It is affected by the matching size and corrosion degree of the gland sealing surface, and the sealing effect is poor.

        5. Compared with the large spring type mechanical seal, the bellows mechanical seal is less affected by the corrosion of the sleeve surface;

        Disadvantages of metal bellows mechanical seal: high price;High production accuracy.
