The Principle of Bellows Mechanical Seal

Bellows mechanical seal is a sealing structure commonly used in high temperature, high pressure and strong corrosive environment. Its main principle is to use the elastic deformation of metal bellows to maintain the gap of mechanical seal surface to prevent medium leakage. Bellows mechanical seal has the advantages of good sealing, long service life and low maintenance cost, so it is widely used in petrochemical, chemical, pharmaceutical, food, papermaking and other fields.
