Description
Technical field
This utility model relates to a kind of detaching tool for flange, particularly relates to a kind of slurry circulating pump demounting flange special tool
Tool, it is adaptable to the single-stage horizontal centrifugal pump dismounting impeller assembly that flange seam fit clearance is less uses.
Background technology
Desulfurization slurry circulating pump is single-stage horizontal centrifugal pump, and running medium is limestone and gypsum slurries.The impeller of this pump
Group is made up of impeller, pump housing bonnet, mechanical sealing assembly, bearing housing assembly etc., and impeller sets and pump case are by pump housing bonnet
During Flange joint is fixed and automatically looked for foremost, bonnet flange faying face and pump case are installed as matched in clearance.After having dismantled pump
During the flange bolt covered, cannot by impeller sets from the matching part of pump case separately the most even cause near jackscrew with jackscrew
Flange is crackle because local stress is excessive.Thus further increase the dismounting difficulty of impeller sets flange.
Utility model content
This utility model is for above-mentioned problems of the prior art, it is provided that a kind of slurry circulating pump demounting flange is special
With instrument, solve the problem that in prior art, impeller sets demounting flange difficulty is big.
The technical solution of the utility model is as follows:
Slurry circulating pump Special tool for demounting flange, including base plate, veneer and screw rod, described base plate includes pedestal
With panel, pedestal and panel are that staged is arranged, pedestal and panel are circular arc；Being provided with through hole on pedestal vertically, screw rod is worn
Cross through hole fastening base；Described veneer is circular arc, and the inner edge diameter of circular arc veneer matches with pedestal upper surface, veneer
Being placed on pedestal, leave gap between veneer and panel, the side of veneer is provided with blind hole.
Described base plate cross sectional shape is L-shaped.
Described veneer cross sectional shape is rectangle, and veneer external profile diameter is identical with panel external profile diameter.
Described blind hole aperture matches with pump case upper flange fastening bolt with position.
Gap between described veneer and panel matches with the thickness of ultrathin separated type hydraulic jack.
Described screw rod is full flight screw, screw flight specification and impeller assembly second level flange fastening bolt phase
With, the length of screw rod is more than the thickness of pedestal.
Described through hole and blind hole are at least provided with two.
The utility model has the advantages of as follows:
This utility model instrument is for being exclusively used in single-stage or other large pump impeller assembly dismantlement works.Main purpose is to make
The more close impeller assembly of fit clearance is more easy to split out in pump case, and does not damage the rear flange outer rim of impeller sets, improves work
Make efficiency, practical, be suitable to popularization and application.

Detailed description of the invention
Embodiment
As it can be seen, slurry circulating pump Special tool for demounting flange, including base plate 1, veneer 2 and screw rod 3, described base
Seat board cross sectional shape is L-shaped, and described base plate 1 includes that pedestal 101 and panel 102, pedestal and panel are that staged is arranged,
Pedestal and panel are circular arc, and pedestal is jack supporting surface, and panel is close to impeller assembly rear pump cover second and encloses flange (inner side
Flange) on；Being provided with two through holes 4 on pedestal vertically, screw rod 3 is arranged on the of impeller sets rear pump cover through through hole fastening base
Two circle flange positions；Described veneer 2 cross sectional shape is rectangle, and described veneer is circular arc, and the outer rim of circular arc veneer is straight
Footpath is identical with panel external profile diameter, and inner edge diameter matches with pedestal upper surface, and veneer is placed on pedestal, veneer and panel it
Between leave gap, gap matches with the thickness of ultrathin separated type hydraulic jack 5, and the side of veneer is provided with two blind holes 6,
Blind hole aperture matches with pump case upper flange fastening bolt with position so that it is in just penetrating hole and firmly by panel 2
Prop up；The another side of panel 2 is plane.
Described screw rod is full flight screw, screw flight specification and impeller assembly second level flange fastening bolt phase
With, the length of screw rod, more than the thickness of pedestal, can meet and is fastened on impeller sets rear pump cover by thicker pedestal, the spiral shell of fastening
Cap can use the nut of same model on the pump housing to replace.
During use, veneer is arranged on the outmost turns flange of pump case, and base plate is arranged on the second circle of impeller assembly pump cover
On flange, the veneer 2 on outmost turns flange is directly nested with on flange fastening stud by two blind holes, supports by pump case and makees
For a working foundation face of hydraulic jack, base plate 1 utilizes the long threaded rod of screw rod 3 to be fixedly attached to by two through holes
On two circle flanges, it is allowed to the pump postoperculum with impeller sets and is integrally forming.The basic process of its dismounting is: first by veneer and base plate
It is respectively mounted and is fixed on two flanges, between veneer and base plate, lay separated type hydraulic jack, according to gap length
Adjust pad, under the effect of jack, be respectively acting on two power of pump case and the impeller sets pump housing by the impeller sets pump housing gradually
Push up from pump case and press out.Also a pair or two pairs of this utility model instruments can be symmetrically installed on the circumference of pump postoperculum, the most same
Step top pressure, until the pump housing is deviate from from pump case.
The above is specific embodiment of the utility model and the know-why used, any based on this utility model
Equivalent transformation on the basis of technical scheme, within belonging to protection domain of the present utility model.
