Research on Key Technology of Shield Machine Main Drive Sealing

Article Preview

Abstract:

Due to poor bonding of a shield machine main drive leading to seal failure sealing fracture failure occurs, the proposed installation forms of adhesive sealing method is replaced by platen method, and seal material NBR replaced by a fluorine rubber, so that the combination of the housing seal is more reliable, avoiding the fracture caused by discontinuity of local sealing. Construction process increases the injection of three different oils enhancing the sealing effect. Through the application of practical project, no failure appears after sealing transformation.
