Abstract
The invention discloses a top shaft sleeve of a wear-resisting electric pump. The top shaft sleeve comprises a stainless steel shaft sleeve and a ceramic shaft sleeve, wherein a limiting platform is respectively arranged at each of the upper end and the lower end of the stainless steel shaft sleeve; two or more than two positioning slots are formed in each of the upper end and the lower end of the stainless steel shaft sleeve; the positioning slots are formed between the two limiting platforms; a platform is arranged on the bottom of each positioning slot; the ceramic shaft sleeve sleeves the stainless steel shaft sleeve and is positioned between the two limiting platforms. The top shaft sleeve of the wear-resisting electric pump is convenient to manufacture, low in cost, and capable of improving the wear resistance of the shaft sleeve, so that the integral service life of a water pump is prolonged.
Description
Technical field
The present invention relates to axle sleeve field, specifically relate to a kind of wear-resisting 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 upper end uses stainless steel axle sleeve and the nitrile butadiene rubber bearing fit being arranged on water exit end center, reaches the effect of centering.There is the nitrile butadiene rubber bearing touch position rapid wear on stainless steel axle sleeve and water exit end in actual use, cause impeller to rock, polarization and inordinate wear, reduce the problem such as pump efficiency and working life.
Summary of the invention
For problems such as the rapid wears that the stainless steel axle sleeve on present small flow multistage deep well submerged electric pump pump shaft exists, the invention provides a kind of electric pump top axle sleeve improving wear-resisting property.It comprises stainless steel axle sleeve and Ceramic shaft sleeve, the top and bottom of described stainless steel axle sleeve are respectively provided with a limiting platform, the top and bottom of described stainless steel axle sleeve are respectively provided with two or more guide slot, described guide slot is between described two limiting platforms, the bottom of described guide slot is a platform, and described Ceramic shaft sleeve is enclosed within described stainless steel shaft and puts and between described two limiting platforms.
Further, the top and bottom of described stainless steel axle sleeve are respectively provided with two guide slots, and two guide slots of described stainless steel shaft set upper side are symmetrical vertically, and two guide slots of described stainless steel axle sleeve lower end are symmetrical vertically.
Further, described Ceramic shaft sleeve is provided with directed projection, and described directed projection inserts described guide slot.
Further, the top and bottom of described stainless steel axle sleeve are respectively provided with three guide slots, 60 ° apart of three guide slots of described stainless steel shaft set upper side, 60 ° apart of three guide slots of described stainless steel axle sleeve lower end.
Further, described Ceramic shaft sleeve and described stainless steel shaft cover fit tightly.
Beneficial effect: the present invention's wear-resisting electric pump top axle sleeve is easily manufactured, with low cost, can improve the wear-resisting property of axle sleeve, thus improve the bulk life time of water pump.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention wear-resisting electric pump top axle sleeve.
Embodiment

The structure of a kind of wear-resisting electric pump top of the present invention axle sleeve is as shown in Fig. 1, comprise stainless steel axle sleeve 1 and Ceramic shaft sleeve 2, the top and bottom of described stainless steel axle sleeve 1 are respectively provided with a limiting platform 12, the top and bottom of described stainless steel axle sleeve 1 are respectively provided with two or more guide slot 11, described guide slot 11 is between described two limiting platforms 12, the bottom of described guide slot 11 is a platform 13, and described Ceramic shaft sleeve 2 to be enclosed within described stainless steel axle sleeve 1 and between described two limiting platforms 12.Consider the characteristic of stupalith, the limiting platform 12 of two ends flange breaks in order to the hard contact of Ceramic shaft sleeve 2 and metalwork when preventing from assembling.
General, in order to reduce the consumption of pottery, only mold symmetrical guide slot 11 at upper and lower two ends, the top and bottom of described stainless steel axle sleeve 1 are respectively provided with two guide slots 11, two guide slots 11 of described stainless steel axle sleeve 1 upper end are symmetrical vertically, and two guide slots 11 of described stainless steel axle sleeve 1 lower end are symmetrical vertically.Between symmetrical guide slot 11, inwall distance equals the distance of any two symmetry plane of electric pump hexagonal axis, and the setting of guide slot 11 bottom platform 13 conveniently fits with electric pump hexagonal axis, ensures its concentricity and synchronous rotary.
Or the top and bottom of described stainless steel axle sleeve 1 are respectively provided with three guide slots 11,60 ° apart of three guide slots 11 of described stainless steel axle sleeve 1 upper end, 60 ° apart of three guide slots 11 of described stainless steel axle sleeve 1 lower end.
Wherein, described Ceramic shaft sleeve 2 is provided with directed projection 21, and described directed projection 21 inserts described guide slot 11; Described Ceramic shaft sleeve 2 fits tightly with described stainless steel axle sleeve 1.
During manufacture, stainless steel axle sleeve 1 and Ceramic shaft sleeve 2 sinter, and form through follow-up external grinding.
