Abstract
The utility model provides a modular compressor dry gas seals assembly and disassembly tools structure, includes main part board (9), lock bracing strut (3), a lock axle pull rod (2), lock nut (1), connecting screw (5), lock bracing strut fixing bolt (4), keeps apart sealed pull rod (10), keeps apart sealed pull rod butterfly nut (13), primary seal pull rod (15), primary seal pull rod butterfly nut (16), top wire receptacle (7), jackscrew (6), kicking block (8) etc.. The utility model discloses a kicking block upper surface V type groove structure has the automatic centering function, ensures that the axle is with sealed concentric. Adopt 4 pull rods to bear, the atress is even. On butterfly nut's gyroscopic moment was used in the main part board, the pull rod only produced the axial force, kept apart during the installation sealedly can not take place rotatoryly with the primary seal. Being equipped with two sets of guiding holes on the main part board, being used for the dismouting to keep apart sealedly and the primary seal respectively, the dismouting is sealed, and it is integrated on the main part board to lift the axle. The lock axle can be accomplished in the combination, measures rotor axle clearance function.
Description
Technical field
This combined dismounting instrument is for centrifugal compressor bearings at both ends, dry gas seals, isolating seal dismounting and installs.Lifting s function, four screw mandrels stress simultaneously can dry gas seals and isolating seal steadily be removed and installation puts in place.It is primarily adapted for use in petrochemical industry, natural gas line centrifugal compressor field.
Background technology
Centrifugal compressor safeguards and in maintenance, dry gas seals and isolating seal dismantled and installation has high requirements.When existing instrument is installed, rotation pushnut can produce the moment along direction of rotation and cause sealing rotation, and time serious, alignment pin can misplace.Also need to crane or lift axle equipment to ensure axle with seal coaxial, operating difficulties, the big installation effectiveness of labor intensity is low, if in installation process unbalance stress or concentricity difference can cause sealing ring damage even sealing ring damage cause economic loss.Incur loss through delay maintenance duration.Measure lock shaft instrument span when axial gap and lock shaft position big.
Utility model content
The technical problems to be solved in the utility model there is provided a kind of combination type compressor dry gas seals dismantling device, improves work efficiency, reduces labor intensity, it is prevented that sealing ring and sealing ring damage.It is provided simultaneously with lifting axle and lock shaft function.
This utility model is realized by following measures:
A kind of combination type compressor dry gas seals dismantling device structure, fixed with compressor shaft bearing (11) by attachment screw (5) including main board (9) outer rim, it is connected by lock shaft bracket fixing bolt (4) with lock shaft support (3), lock shaft pull bar (2) one end is fixed with spindle nose (12), utilizes 2 locking nuts (1) and lock shaft support (3) to complete lock shaft.When removing isolating seal, by 4 isolating seal pull bars (10) with isolating seal (14) installing hole with threadeding, corresponding through hole on main board.Adjusting the jackscrew (6) on top screw seat (7) promotes jacking block (8) to make axle be in center.Installation isolating seal pull bar wing nut (13) rotates wing nut symmetrically and evenly and is split out by isolating seal, and during installation, the anti-turnback of wing nut acts on inside main board, rotates wing nut symmetrically and evenly until installing and putting in place.When splitting out primary seal (20), first mounting disc (17) is connected fixing by stationary ring screw (18), rotating ring screw (19) with primary seal (20).Again by 4 primary seal pull bars (15) with installing hole in mounting disc with threadeding, corresponding through hole on main board.Axle is made to be in center.Installation primary seal pull bar wing nut (16) rotates wing nut symmetrically and evenly and is split out by isolating seal, and during installation, the anti-turnback of wing nut acts on inside main board, rotates wing nut symmetrically and evenly until installing and putting in place.
The beneficial effects of the utility model: when lifting axle, jacking block upper surface V-groove structure has self-centering function, it is ensured that axle is concentric with sealing.Adopt 4 pull bar carryings, uniform force, effectively prevent excessive damage of local pressure from sealing.The turning moment of wing nut acts on main board, and isolating seal pull bar and primary seal pull bar only produce axial force, and during installation, isolating seal and primary seal will not rotate, it is ensured that the accuracy of location.Main board is provided with two groups of pilot holes, is respectively used to dismounting isolating seal and primary seal, compact conformation, and dismounting seals, and lifts axle and is integrated on main board.It is bolted combination to complete lock shaft, measure rotor axial gap function.
