Fourth, the assembly is carried out under extremely clean conditions, and the working surface of the part is free of bumps, scratches, burrs and other attachments;
Fifth, strict operating procedures, seals should be installed correctly to prevent deformation when not in place;
Sixth, master the performance specifications and use requirements of seals, and replace failed parts in a timely manner;
