Abstract
The utility model discloses a compound type shaft sleeve at the top of an electric pump. The compound type shaft sleeve comprises a stainless-steel bush and a ceramic bush, wherein the upper end and lower end of the stainless-steel bush are respectively provided with a limiting step and two or more than two directional grooves; the directional grooves are positioned between the two limiting steps; a platform is arranged at the bottoms of the directional grooves; the ceramic bush is sheathed on the stainless-steel bush and is positioned between the two limiting steps. The compound type shaft sleeve disclosed by the utility model has the advantages that the manufacture is convenient, the cost is low, and the wear resistance of the shaft sleeve can be improved, so that the whole service life of a water pump is prolonged.
Description
Technical field
The utility model relates to axle sleeve field, specifically relates to a kind of compound electric pump top axle sleeve.
Background technique
The pump shaft of existing small flow multistage deep well submerged electric pump is stainless steel hexagonal axis, and lower end is connected rear and motor shaft end spline joint with coupling, and stainless steel axle sleeve and the nitrile butadiene rubber bearing fit that is arranged on water exit end center are used in upper end, reaches the effect of centering.There is in actual use the nitrile butadiene rubber bearing contact position rapid wear on stainless steel axle sleeve and water exit end, cause that impeller rocks, polarization and inordinate wear, reduce the problems such as pump efficiency and working life.
Model utility content
(1) technical problem that will solve
The problems such as rapid wear that exist for the stainless steel lining on present small flow multistage deep well submerged electric pump pump shaft, provide a kind of compound electric pump top axle sleeve that improves wear-resisting property.
(2) technological scheme
For achieving the above object, the utility model provides a kind of compound electric pump top axle sleeve, comprise stainless steel lining and ceramic chamber lining, the top and bottom of described stainless steel lining are respectively provided with a limited step, the top and bottom of described stainless steel lining are respectively provided with two or more guide slots, described guide slot is between described two limited steps, and the bottom of described guide slot is a platform, and described ceramic chamber lining is enclosed within that described stainless steel lining puts and between described two limited steps.
Further, the top and bottom of described stainless steel lining are respectively provided with two guide slots, and two guide slots of described stainless steel lining set upper side are symmetrical vertically, and two guide slots of described stainless steel lining lower end are symmetrical vertically.
Further, described ceramic chamber lining is provided with directed projection, and described directed projection inserts described guide slot.
Further, the top and bottom of described stainless steel lining are respectively provided with three guide slots, and three guide slots of described stainless steel lining set upper side are each other at a distance of 60 °, and three guide slots of described stainless steel lining lower end are each other at a distance of 60 °.
Further, described ceramic chamber lining and described stainless steel lining cover fit tightly.
(3) beneficial effect
The compound electric pump of the utility model top axle sleeve is easily manufactured, with low cost, can improve the wear-resisting property of axle sleeve, thereby improve the bulk life time of water pump.
Accompanying drawing explanation
Fig. 1 is the structural representation of the compound electric pump of the utility model top axle sleeve;
Fig. 2 is the structural representation of stainless steel lining in the axle sleeve of the compound electric pump of the utility model top;

Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for illustrating the utility model, but are not used for limiting scope of the present utility model.
The structure of a kind of compound electric pump of the present utility model top axle sleeve as shown in Figure 1, Figure 2 and Figure 3, comprise stainless steel lining 1 and ceramic chamber lining 2, the top and bottom of described stainless steel lining 1 are respectively provided with a limited step 12, the top and bottom of described stainless steel lining 1 are respectively provided with two or more guide slots 11, described guide slot 11 is between described two limited steps 12, the bottom of described guide slot 11 is a platform 13, and described ceramic chamber lining 2 is enclosed within on described stainless steel lining 1 and between described two limited steps 12.Consider the characteristic of stupalith, the limited step 12 of two ends flange is that ceramic chamber lining 2 breaks with rigid contact of metalwork in order to prevent from assembling.
General, in order to reduce ceramic consumption, only at upper and lower two ends, mold symmetrical guide slot 11, the top and bottom of described stainless steel lining 1 are respectively provided with two guide slots 11, two guide slots 11 of described stainless steel lining 1 upper end are symmetrical vertically, and two guide slots 11 of described stainless steel lining 1 lower end are symmetrical vertically.Symmetrical 11 inwall distances of guide slot equal the distance of any two symmetry plane of electric pump hexagonal axis, and the setting of guide slot 11 bottom platform 13 is to fit with electric pump hexagonal axis for convenient, guarantees its concentricity and synchronous rotary.
Or the top and bottom of described stainless steel lining 1 are respectively provided with three guide slots 11, three guide slots 11 of described stainless steel lining 1 upper end are each other at a distance of 60 °, and three guide slots 11 of described stainless steel lining 1 lower end are each other at a distance of 60 °.
Wherein, described ceramic chamber lining 2 is provided with directed projection 21, and described directed projection 21 inserts described guide slot 11; Described ceramic chamber lining 2 fits tightly with described stainless steel lining 1.
During manufacture, stainless steel lining 1 and ceramic chamber lining 2 sintering, and form through follow-up external grinding.
The beneficial effects of the utility model: easily manufactured, with low cost, can improve the wear-resisting property of axle sleeve, thereby improve the bulk life time of water pump.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
