Abstract
The utility model belongs to the technical art of a centrifugal pump and particularly to technical improvement of the dismantled impeller structure of a slurry pump, which mainly comprises a rotator elements formed by a bearing on the pump shaft, a water barrier pan, dismantled impeller block bush, a shaft liner, a flybar impeller and a blade and a ring dismantled impeller made of ceramics materials is arranged between the shaft liner and the water barrier pan. When dismantled for inspection, the block bush of the dismantled impeller made of ceramics materials are slightly broken into pieces to loose the whole rotator elements, eliminate the friction forces on the end surface and conveniently dismantle the impeller; compared with the prior technologies, the utility model does not have a lower costs, save much processing and mounting and dismantling expenses and is convenient and quick for dismantling, thus basically resolve the issue of dismantling impellers.
Description
Technical field
The utility model belongs to the centrifugal pump technical field, specifically is a kind of technological improvement of tearing blade wheel structure open of slag stock pump.
Background technique
In the prior art, the dismounting slurry pump impeller mainly relies on tears that the impeller interstage sleeve finishes open on the rotor part, and its main effect is the dismounting of being convenient to impeller when pump overhauls.The impeller interstage sleeve of tearing open shown in Figure 4 is a kind of petal type structure.To be wrapped on the axle by the impeller interstage sleeve of tearing open that several parts are formed during use, shaft block ring and guard ring double fixed are adopted in the outer ring.Remove shaft block ring earlier before the dismounting impeller, again guard ring is axially shifted out and tear the impeller interstage sleeve open, radially split out petal type with bolt then and tear the impeller interstage sleeve open, itself and axle are broken away from, whole thereupon rotor part is in axial play, eliminate the end-face friction between each part, thereby played the effect of being convenient to dismantle impeller.Fig. 2, the impeller interstage sleeve of tearing open shown in Figure 3 are split type bolt fastening structures.This impeller interstage sleeve of tearing open is with the bolt connection and attached on the axle.With bolt split type interstage sleeve is radially split out before the dismounting impeller, same as above, reach the purpose of dismantling impeller.But these two kinds of structures are in the application of reality, and effect is not so good.Reason is that pump is in running, the lasting interaction of impeller blade and institute's slurry body, make whole rotor part constantly fastening in the axial direction, no matter the impeller interstage sleeve of tearing open of petal type or split-type structural also is difficult to loosening under powerful face pressure, cause that to remove the impeller interstage sleeve just very difficult, more do not have the effect of being convenient to dismantle impeller.No matter how manufacturer improves tearing open on the blade wheel structure, and effect is not very desirable.
Summary of the invention
The utility model overcomes complex structure in the prior art, does not have the drawback of really being convenient to dismantle impeller, provides a kind of simple in structure, and the blade wheel structure of tearing open of convenient disassembly is promptly used pottery instead and torn the impeller interstage sleeve open.
The utility model is realized by following scheme: a kind of slag stock pump tear blade wheel structure open, by being contained in bearing, water retaining disk on the pump shaft, tearing the impeller interstage sleeve open, axle sleeve, pay impeller and impeller mutual group slagging stock pump rotor part, the ring made from stupalith is torn the impeller interstage sleeve open and is contained between axle sleeve and the water retaining disk.Adopt pottery to tear the impeller interstage sleeve open.When pump was opened and inspect, the impeller interstage sleeve of tearing open that only needs stupalith is made smashed gently, just can make whole rotor part loosening, had shed end-face friction, just can realize the dismounting of impeller very easily.
The utility model is compared with prior art not only with low cost, has saved many processing and mounting or dismounting expense, and convenient disassembly, quick, has fundamentally solved the dismounting problem of impeller.

Embodiment
In conjunction with the accompanying drawings embodiment is further described, present embodiment is to be used for illustrating of the present utility model, rather than the utility model is carried out any restriction.
A kind of slag stock pump tear blade wheel structure open, mainly by being contained in bearing 2, water retaining disk 3 on the pump shaft 1, tearing impeller interstage sleeve 4, axle sleeve 5 open, paying impeller 6 and impeller 7 mutual group slagging stock pump rotor parts constitute.Rotor part dependence impeller makes with being threaded of spindle nose and comprises that each part of tearing impeller interstage sleeve 4 open tightly is locked on the axle.The ring made from the stupalith with certain intensity is torn impeller interstage sleeve 4 open and is contained between axle sleeve 5 and the water retaining disk 3.When pump was opened and inspect, the impeller interstage sleeve 4 of tearing open that only needs stupalith is made smashed gently, just can make whole rotor part in axial play, has shed end-face friction, just can realize the dismounting of impeller very easily.
Claims (1)
1, a kind of slag stock pump tears blade wheel structure open, comprise the bearing (2), the water retaining disk (3) that are contained on the pump shaft (1), tear impeller interstage sleeve (4) open, axle sleeve (5), pay impeller (6) and impeller (7) mutual group slagging stock pump rotor part, it is characterized in that ring that stupalith is made tears impeller interstage sleeve (4) open and be contained between axle sleeve (5) and the water retaining disk (3).
