Advantages of metal bellows mechanical seal

Metal bellows mechanical seals have a wide range of applications, from low temperature to high temperature, from neutral media to corrosive media, from low speed to high speed, and from ordinary to harsh working conditions.

Advantages of metal bellows mechanical seal:

1. The sealing end face of the bellows mechanical seal is relatively evenly stressed;

2. Simple structure, easy installation, strong adaptability, and the static ring is floating.

3. The bellows mechanical seal has good tracking performance and can, to a certain extent, compensate for the end clearance (generally required to be less than 1μm), thereby reducing the leakage of mechanical seals;

4. The static ring of the bellows mechanical seal is fastened to the mechanical seal gland with bolts. Most of the static rings of spring-type mechanical seals basically rely on the excessive cooperation between the O-ring seal and the mechanical seal gland, as well as the action of fluid pressure and external springs to seal. This is subject to the matching size and size of the gland sealing surface. Influenced by the degree of corrosion, the sealing effect is poor.

5. Compared with large spring-type mechanical seals, bellows mechanical seals are less affected by corrosion on the surface of the shaft sleeve;
