Abstract
The utility model discloses an impeller pump shaft, which comprises an impeller locking nut mounting part, an impeller mounting part and a shaft sleeve mounting part sequentially. A first arc-shaped chamfer is arranged between the impeller locking nut mounting part and the impeller mounting part of the impeller pump shaft, a second arc-shaped chamfer is arranged between the impeller mounting part and the shaft sleeve mounting part, and the shaft sleeve mounting part of the impeller pump shaft is provided with a single-layer shaft sleeve. No cutter retraction slot is processed between the impeller locking nut mounting part and the impeller mounting part of the impeller pump shaft, but the first arc-shaped chamfer of R3-R5 is arranged instead. No cutter retraction slot is processed between the impeller mounting part and the shaft sleeve mounting part, but the second arc-shaped chamfer of R3-R5 is arranged instead. Due to the arc-shaped chamfers, stress can be dispersed in a concentrated way, so that the impeller pump shaft of a circulating pump cannot be broken easily. The impeller pump shaft has a simple and reasonable structure. By adopting the impeller pump shaft, breakage can be avoided effectively, and wear can be reduced.
Description
Technical field
The utility model relates to a kind of pump machines, relates to a kind of impeller shaft specifically.
Background technique
In the zinc hydrometallurgy industry, 80 percent recycle pump adopts 904 expensive stainless steel metal recycle pumps in the electrolysis workshop section circulatory system, 904 stainless steel metal recycle pumps of the prior art use as impeller shaft shown in Figure 1 in the Figure of description, comprise impeller locknut assembly department, impeller assembly department and axle sleeve assembly department, this impeller shaft all be reserved with tool withdrawal groove 6 at an impeller locknut assembly department and an axle ladder position, tool withdrawal groove 6 reduces the diameter of impeller shaft greatly, stress is concentrated under equal torsional interaction increases, cause the impeller shaft fracture, key 7 is with respect to keyway displacement, axle sleeve 8 and impeller shaft heavy wear.904 stainless steel metal recycle pumps of the prior art in use, project organization problem because of impeller shaft, average every three months all can be in the fracture of impeller position once, and because structure unreasonable, also can cause axle sleeve 8 and axle heavy wear, impeller shaft after the wearing and tearing need be taken machine shop and repeat to repair, each maintenance needs to change the 904 stainless steel round steel of about Φ about 100 * 500, about 5,000 yuan of generation expense, one of electrolytic process, two, three phases hypothesis has 21 of 904 stainless steel metal recycle pumps, three above impeller shafts of maintenance in average every month, ten thousand yuan of generation expenses every month at least two, not only brought certain influence, and maintenance expenses can increase greatly thereupon also, how provide a kind of impeller shaft of impeller shaft fracture and wear problem of effectively avoiding to become the urgent demand of people to production.
The model utility content
The purpose of this utility model is to overcome deficiency of the prior art, provides a kind of and can effectively avoid rupturing and the impeller shaft of mitigate wear.
The purpose of this utility model realizes by following scheme: a kind of impeller shaft, described impeller shaft is followed successively by impeller locknut assembly department, impeller assembly department and axle sleeve assembly department, be provided with first circular arc chamfering between the impeller locknut assembly department of described impeller shaft and the impeller assembly department, be provided with second circular arc chamfering between described impeller assembly department and the axle sleeve assembly department, be provided with solid bearing bush at the axle sleeve assembly department of described impeller shaft.
Described first circular arc chamfering and second circular arc chamfering all are the circular arc chamferings of R3～R5.
Advantage of the present utility model is: impeller shaft of the present utility model is not processed tool withdrawal groove between impeller locknut assembly department and impeller assembly department, but adopt first circular arc chamfering of R3～R5 to replace, between described impeller assembly department and axle sleeve assembly department, do not process tool withdrawal groove yet, adopt second circular arc chamfering of R3～R5 to replace, circular arc chamfering concentrate to disperse stress, and then the axle pump that makes recycle pump easy-rupturing not.Axle sleeve assembly department at described pump shaft is provided with solid bearing bush, the double-deck axle sleeve that has keyway before being compared to, solid bearing bush has reduced the wearing and tearing of axle, but also the operation and the expense of having saved the processing double-layer axle sleeve, be a kind of simple and reasonable, can effectively avoid the impeller shaft of pump shaft fracture and wear problem.A kind of impeller shaft of the utility model passes through related personnel's test of many times and conscientiously proves, now solved the disconnected and wear problem of pump shaft fully, of the present utility modelly inner use of our unit off-axis and wear phenomenon do not take place so far one year over, directly or indirectly economize on the use of funds about 500,000 yuan every year.
Description of drawings
Fig. 1 is the structural representation of the impeller shaft of prior art;
Fig. 2 is the structural representation of impeller shaft of the present utility model;
In Fig. 1, include:
6 tool withdrawal grooves; 7 keys; 8 axle sleeves.
In Fig. 2, include:
1 impeller locknut assembly department; 2 impeller assembly departments; 3 axle sleeve assembly departments; 4 first circular arc chamferings; 5 second circular arc chamferings.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described further.
As shown in Figure 2, a kind of impeller shaft, described impeller shaft is followed successively by impeller locknut assembly department 1, impeller assembly department 2 and axle sleeve assembly department 3, be provided with first circular arc chamfering 4 between the impeller locknut assembly department 1 of described impeller shaft and the impeller assembly department 2, be provided with second circular arc chamfering 5 between described impeller assembly department 2 and the axle sleeve assembly department 3, be provided with solid bearing bush at the axle sleeve assembly department 3 of described impeller shaft.Described first circular arc chamfering 4 and second circular arc chamfering 5 all are the circular arc chamferings of R3～R5.
Should be noted that at last; above content is only in order to the explanation the technical solution of the utility model; but not to the restriction of the utility model protection domain; the simple modification that those of ordinary skill in the art carries out the technical solution of the utility model or be equal to replacement does not all break away from the essence and the scope of technical solutions of the utility model.
