Abstract
The invention discloses a multi-stage pump shaft sleeve quick disassembling device. The multi-stage pump shaft sleeve quick disassembling device comprises a subdivision round ring, wherein the diameter of an inner hole of the subdivision round ring is smaller than the outer diameter of a shaft sleeve, the end surface of the subdivision round ring is provided with a pair of bulges, the bulges are provided with a pair of threaded holes, the threaded holes are assembled and connected with screws, the subdivision round ring is symmetrically provided with a pair of through holes in the radial direction, the through holes are fixedly connected with the ends of pulling rods, the other ends of the pulling rods are fixedly provided with a limiting ejector plate, the center of the limiting ejector plate is provided with a threaded hole, the threaded hole is internally assembled with a screw rod, and the outer end of the screw rod is fixedly provided with a nut. The inner hole of the subdivision round ring can be in tight contact with the surface of the shaft sleeve of a pump, the screw rod in a bearing plate can be aligned to the center of the end surface of a pump shaft, the nut can be rotated by sleeving a wrench on the nut of the screw rod, and thus a multi-stage pump shaft can be slowly pulled out. The multi-stage pump shaft sleeve quick disassembling device disclosed by the invention has the advantages that the maintenance is convenient, and the device is not damaged.
Description
Technical field
The present invention relates to a kind of multistage pump axle sleeve quick-release arrangement.
Background technology
Centrifugal multistage pump, in industrial production, is important chemical industry conveying equipment, have large flow high-lift, and floor space is little.Such pump is compact to design, the plural pump with said function is gathered together, be connected on fluid channel structure, the medium pressure relief opening that shows the first order communicates with the import of the second level, the medium pressure relief opening of the second level communicates with the import of the third level, so the mechanism of series connection has formed centrifugal multistage pump multiple centrifugal pump, thereby has improved system pressure.
Because this pump is compact to design, aspect maintenance of equipment, acquire a certain degree of difficulty, this is less in the gap of axle and shaft room, use in intermediate gap and produce iron rust, mud etc., several axle sleeves are together assemblied on axle, due to radially very close to each other, sleeve outer surface is smooth, not having can be for tearing the convex drawing open, and like this, dismounting and change axle sleeve is more difficult, sometimes only have destructive dismounting, and destructive dismounting has local damage to part of appliance, and the repair time is long, has a strong impact on production.
Summary of the invention
For the deficiencies in the prior art part, the present invention aims to provide a kind of multistage pump axle sleeve quick-release arrangement, to guarantee not destroy multistage pump axle sleeve, and the fast fast reparation of energy, the repair time of shortening equipment, promptly put into production, guarantee the steady propelling of producing.
For solving the problems of the technologies described above, the technical solution used in the present invention: a kind of multistage pump axle sleeve quick-release arrangement, comprise a subdivision annulus, the diameter of bore of subdivision annulus is less than axle sleeve external diameter, subdivision annulus end face has a pair of projection, a pair of screwed hole is set in projection, in screwed hole, assemble joint bolt, in subdivision annulus radial symmetric, a pair of through hole is set, the described through hole pull bar one end that is fixedly connected, at the fixing spacing top board of the pull bar other end, arranges a screwed hole at spacing top board center, in screwed hole, assemble screw rod, the outer end of screw rod is fixed with nut.
Adopt technique scheme, subdivision annulus is connected into one by projection, subdivision annulus is installed to and needs the pump shaft of dismounting to put, then tighten the joint bolt in subdivision annulus nut, make endoporus and the pump shaft of subdivision annulus overlap surperficial close contact, again screw rod in spacing top board is aimed to pump shaft end face center, be enclosed within spanner on the nut of screw rod and rotate, just multistage pump axle sleeve can be extracted at leisure.
Adopt above-mentioned special purpose device, simple in structure, maintenance is convenient, does not destroy equipment, and the repair time is short, can put into production rapidly, does not affect production.
accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is subdivision circular ring structure schematic diagram;
In accompanying drawing: spacing top board 6 screw rods of 1 axle sleeve 2 subdivision annulus 3 pull bar 4 pump shaft 5
Protruding 9 screws of 7 impeller of pump 8.
The specific embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
As Fig. 1, shown in Fig. 2, a kind of multistage pump axle sleeve quick-release arrangement, comprise a subdivision annulus 2, the diameter of bore of subdivision annulus 2 is less than axle sleeve 1 external diameter, the endoporus of subdivision annulus 2 and axle sleeve 2 surfaces just have the condition that produces interference fit like this, axle sleeve 2 is assemblied in pump shaft 4 one end, on the other end of pump shaft 4, be provided with multiple impellers of pump 7, subdivision annulus 2 end faces have a pair of protruding 8, namely at two subdivision bodies, projection 8 is set, in projection 8, a pair of screwed hole is set, in screwed hole, assemble joint bolt 9, by screw 9, subdivision annulus 2 is connected into entirety, and by adjustment screw 9, make subdivision annulus 2 endoporus and axle sleeve 1 surface be interference fit, in subdivision annulus 2 radial symmetric, a pair of through hole is set, described through hole assembling connects pull bar 3 one end, at the fixing spacing top board 5 of pull bar 3 other ends, certainly, on spacing top board 5, there is a pair of through hole to coordinate with pull bar 3 one end, in order to regulate distance between spacing top board 5 and subdivision annulus 2, in all machining screw of pull bar 3 two ends, and assembling nut, rotating nut just can regulate distance between spacing top board 5 and subdivision annulus 2, spacing top board 5 centers arrange a screwed hole, in screwed hole, assemble screw rod 6, the outer end of screw rod 6 is fixed with nut.
