Abstract
The utility model relates to a quiet ring mounting tool of centrifugal pump mechanical seal. Cause fish tail, atress inequality to arouse the sealed bad problem of effect easily in mainly having solved the current fixed mechanical sealing ring installation that exists among the prior art. Its characterized in that: 2 round holes that the last both ends in base (8), top cap (2) correspond about opening and having, base (8), top cap (2) both ends correspond has from top to bottom worn single -end positioning bolt (3) fixed connection between the round hole, it has the round hole to open in the middle of top cap (2), has worn in the round hole in the middle of top cap (2) single -end bolt (1), base (8) overhead seals gland (7) organically, and the machine seals gland (7) upper portion and has placed fixed mechanical sealing ring (5), has put between fixed mechanical sealing ring (5) and single -end bolt (1) circular press plate (4). This quiet ring mounting tool of centrifugal pump mechanical seal can make fixed mechanical sealing ring installation atress even, and there is not the fish tail phenomenon in sealed face, guarantees the sealed effect that the warpout sealed.
Description
Technical field
The utility model relates to a kind of aid in flight-line maintenance assembling field, particularly a kind of mechanical face seals of centrifugal pumps stationary ring erecting tools.
Background technology
In daily pump maintenance process, mechanical seal is easy leak site, changing machine envelope is one of main maintenance items of centrifugal pump maintenance, changing machine seals the rotating ring and stationary ring that just need fitting machine to seal, in traditional installations, maintenance personal uses other instrument fitting machine envelope stationary rings such as tetrafluoro rod, nylon rod (φ 25X200) hand hammer, be installed in the process of machine sealed cover machine being sealed stationary ring, because stationary ring material is graphite material, be easy to the rubbing surface of scuffing machine envelope stationary ring, thus cause machine to seal leakage.And conventional mounting arrangements machine envelope stationary ring discontinuity, the sealing effectiveness that the machine that can not ensure seals.
Summary of the invention
Technical problem to be solved in the utility model be overcome in the existing machine envelope stationary ring installation process that exists in background technology easily cause scuffing, problem that unbalance stress causes sealing effectiveness bad, and a kind of mechanical face seals of centrifugal pumps stationary ring erecting tools is provided, this mechanical face seals of centrifugal pumps stationary ring erecting tools, machine can be made to seal stationary ring uniform force is installed, there is not scuffing phenomenon in sealing surface, the sealing effectiveness that the machine that ensure that seals.
The invention for solving the technical problem reaches by following technical scheme: this mechanical face seals of centrifugal pumps stationary ring erecting tools, comprises base, top cover, and on described base, top cover, two ends have 2 corresponding up and down circular holes; Be installed with single head bolt between described base, the upper and lower corresponding circular hole in top cover two ends to be fixedly connected with; Have circular hole in the middle of described top cover, in the middle of top cover, in circular hole, be installed with single ended bolt; Described base is equipped with machine sealed cover, organic envelope stationary ring is placed on machine sealed cover top, is equipped with circular pressing plate between machine envelope stationary ring and single ended bolt.
The utility model can have following beneficial effect compared with above-mentioned background technology: this mechanical face seals of centrifugal pumps stationary ring erecting tools is owing to adopting said structure, machine sealed cover is lain on base, machine envelope stationary ring and machine sealed cover centering, circular pressing plate lies on machine envelope stationary ring, top cover is pressed on circular pressing plate, located by single ended bolt, bonding hook bolt, circular pressing plate, machine envelope stationary ring, machine sealed cover are concentric.Fastening single ended bolt, circular pressing plate is stressed to be moved downward, and makes machine seal stationary ring uniform stressed and installs.Machine envelope stationary ring installs uniform force, and sealing surface does not exist scuffing phenomenon, the sealing effectiveness that the machine that ensure that seals.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model;
Accompanying drawing 2 is top views of top cover of the present utility model.
In figure: 1-single ended bolt, 2-top cover, 3-single head bolt, the circular pressing plate of 4-, 5-machine envelope stationary ring, 6-O type circle, 7-machine sealed cover, 8-base.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Shown in accompanying drawing 1 composition graphs 2, this mechanical face seals of centrifugal pumps stationary ring erecting tools, comprises U-shaped trough-shaped base 8, top cover 2, and on described base 8, top cover 2, two ends have 2 corresponding up and down circular holes; Be installed with single head bolt 3 between described base 1, the upper and lower corresponding circular hole in top cover 2 two ends to be fixedly connected with; Have circular hole in the middle of described top cover 2, in the middle circular hole of top cover 2, be installed with single ended bolt 1; Described base 8 is equipped with machine sealed cover 7, and organic envelope stationary ring 5 is placed on machine sealed cover 7 top, is equipped with circular pressing plate 4 between machine envelope stationary ring 5 and single ended bolt 1; Described machine sealed cover 7 and machine seal between stationary ring 5 and are equipped with O type circle 6.Described base 1, upper and lower corresponding circular hole both sides, top cover 2 two ends also have some circular holes, for regulating the spacing that single head bolt 3 is housed, are convenient to the machine envelope stationary ring installing different size.
When this mechanical face seals of centrifugal pumps stationary ring erecting tools uses, machine sealed cover is lain on base, machine envelope stationary ring and machine sealed cover centering, circular pressing plate lies on machine envelope stationary ring, top cover is pressed on circular pressing plate, located by single ended bolt, bonding hook bolt, circular pressing plate, machine envelope stationary ring, machine sealed cover are concentric.Fastening single ended bolt, circular pressing plate is stressed to be moved downward, and makes machine seal stationary ring uniform stressed and installs.Machine envelope stationary ring installs uniform force, and sealing surface does not exist scuffing phenomenon, the sealing effectiveness that the machine that ensure that seals.
