Abstract

The invention relates to a sealing device of a rotating shaft, in particular to an integrated double mechanical seal. The integrated double mechanical seal comprises a driving seat, a static ring, a movable ring I, a movable ring II and a floating driving device; the movable ring II and the movable ring I sleeve the outer side of the driving seat in sequence from inside to outside; the inner wall of the movable ring II is in sealed connection with the driving seat; one ends of the movable ring I and the movable ring II are connected with the driving seat through the floating driving device; the other ends of the movable ring I and the movable ring II cling to the static ring. The integrated double mechanical seal is compact in structure, convenient to detach and stable and reliable in use, reasonably selects sealing materials, efficiently utilizes the sealing space, gives play to the excellent mechanical sealing performance to the greatest extent and solves the problem of easiness in scaling and the sealing problem of medium containing sand and the like.

Description

technical field [0001] The invention relates to a sealing device of a rotating shaft, in particular to an integrated double-face mechanical seal. Background technique [0002] According to the requirements of API610 standard production pump, the supporting seal should be produced according to API682 standard. The pump has a standard sealing cavity, and the size of the matching sealing structure should be in accordance with DIN24960 or GB6556. The symbol standard seal has good interchangeability, compact structure, and stable performance in conventional media. When the standard seal is used in media that is prone to fouling and sand, the service stability is seriously insufficient, and short-term failures often occur. The current targeted solution is to use two sets of seals in series or parallel arrangement, the structure is complex and takes up a large axial space, and the cost of sealing increases. Contents of the invention [0003] In view of the above problems, the ...
