Problems solved by technology

[0004] In order to avoid the relative movement of the dynamic and static ring surfaces due to the adjustment of the dynamic and static rings during the mechanical seal assembly process, resulting in damage to the sealing surface, the traditional mechanical seal assembly process installs the dynamic and static ring components separately. This method is not suitable for the assembly of the dynamic and static ring components. Box-in-box mechanical seal

Abstract

The invention belongs to the technical field of rotating equipment assembly, and particularly relates to an assembling tool and method for a box-packed mechanical seal. By adopting the tool and method, the risk of friction failure of a moving ring and a static ring in the assembly process of the box-packed mechanical seal can be completed avoided, and meanwhile, the assembly quality and efficiencyof the box-packed mechanical seal are ensured. According to the tool and method, the risk of the friction failure of the moving ring and the static ring in the assembly process of the box-packed mechanical seal is avoided; and aiming at the structural characteristics of the box-packed mechanical seal, a moving ring assembly and a static ring assembly are prevented from being assembled separately,and the assembly working quality and efficiency are improved.

Description

technical field [0001] The invention belongs to the technical field of rotating equipment assembly, and in particular relates to an assembly tool and method for a boxed mechanical seal. Background technique [0002] The mechanical seal components rely on the micron-level thickness of the sealing liquid film on the end faces of the dynamic and static seal rings to realize the axial sealing function of the rotating machinery. [0003] The dynamic and static sealing ring is the core functional part of the mechanical seal, and the positioning in the circumferential direction is realized by the anti-rotation pin installed on each part. [0004] In order to avoid the relative movement of the dynamic and static ring surfaces due to the adjustment of the dynamic and static rings during the mechanical seal assembly process, resulting in damage to the sealing surface, the traditional mechanical seal assembly process installs the dynamic and static ring components separately. This meth...
