Abstract
The utility model discloses a wear -resisting magnetic force pump shaft sleeve, including the axle sleeve body that adopts flexible graphite to make, the axle sleeve body be equipped with the cylindric structure of through -hole for the center, the through -hole in the side surface be provided with the oil groove, the oil groove be helical configuration, the axle sleeve body on the surface the spraying have one deck wear -resistant coating, the coating be polytetrafluoroethylene, molybdenum disulfide and polyamideimide resin's mixture. In this way, the utility model discloses simple structure has better lubricated effect between axle sleeve and the pivot, the wear -resistant paint can effectively strengthen the rub fastness of axle sleeve, improves the wearability and the rub resistance of axle sleeve, can bear the axle sleeve and because of the friction loss that idle running caused, prolong its life, is worth promoting.
Description
Technical field
The utility model relates to Pump Body Parts field, particularly relates to a kind of wear-resisting magnetic drive pump axle sleeve.
Background technique
The axle sleeve of magnetic drive pump mainly plays shaft seal effect also referred to as separation sleeve in magnetic force driving pump, is to embody leak free sole component.In magnetic drive pump, running shaft does not stretch out from fixed pump body, and instead of gland seal device with separation sleeve, prevent the highly pressurised liquid in the pump housing from spilling, prevent the highly pressurised liquid in the pump housing from spilling simultaneously, prevent air from entering in the pump housing simultaneously, so magnetic drive pump is provided with seal arrangement, isolate with axle sleeve between axle and the pump housing, instead of gland seal device, graphite bushing is main base material with graphite material, graphite bushing has selflubricating, high temperature resistant, corrosion-resistant, the features such as light weight, for prior art, the axle sleeve of magnetic drive pump in use often damages, the friction damage that its reason mostly is the inevitable idle running of axle sleeve generation and causes, existing magnetic drive pump axle sleeve cannot bear the wearing and tearing be subject to because of free-runing operation.
Model utility content
The technical problem that the utility model mainly solves is to provide a kind of wear-resisting magnetic drive pump axle sleeve, can improve wear resistance and the rub resistance of axle sleeve.
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: provide a kind of wear-resisting magnetic drive pump axle sleeve, it is characterized in that, comprise: adopt the sleeve body that Expanded graphite is made, the cylinder-like structure of through hole is provided with centered by described sleeve body, described through hole inner surface is provided with oil groove, described oil groove is helicoidal structure, described sleeve body is coated with one deck wear resistant coating on the surface, and described coating is the mixture of teflon, molybdenum disulfide and polyamide-imide resin.
In the utility model preferred embodiment, described wear resistant coating comprises the teflon semisolid lubricant of 20%, the molybdenum disulfide solid lubricant of 30% and polyamide-imide resin.
In the utility model preferred embodiment, the cross section of described oil groove is trapezium structure.
In the utility model preferred embodiment, described oil groove arranges in the shape of a spiral.
The beneficial effects of the utility model are: the utility model structure is simple, good lubrication effect is had between axle sleeve and rotating shaft, wear-resistant paint effectively can strengthen the rub proofness of axle sleeve, improve wear resistance and the rub resistance of axle sleeve, the frictional loss that axle sleeve causes because of idle running can be sustained, extend its working life, be worthy to be popularized.
Accompanying drawing explanation
In order to be illustrated more clearly in the technological scheme in the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, wherein:
Fig. 1 is the structural representation of a kind of wear-resisting magnetic drive pump axle sleeve one of the utility model preferred embodiment;
In accompanying drawing, the mark of each parts is as follows: 1-sleeve body, 2-through hole, 3-oil groove.
Embodiment
Be clearly and completely described to the technological scheme in the utility model embodiment below, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, the utility model is embodiment comprise:
A kind of wear-resisting magnetic drive pump axle sleeve, it is characterized in that, comprise: adopt the sleeve body 1 that Expanded graphite is made, the cylinder-like structure of through hole 2 is provided with centered by described sleeve body 1, described through hole 2 inner surface is provided with oil groove 3, described oil groove 3 is helicoidal structure, and described sleeve body 1 is coated with one deck wear resistant coating on the surface, and described coating is the mixture of teflon, molybdenum disulfide and polyamide-imide resin.
Be different from prior art.
In another embodiment, described wear resistant coating comprises the teflon semisolid lubricant of 20%, the molybdenum disulfide solid lubricant of 30% and polyamide-imide resin, this coating forms wear-resisting lubricating layer when axle sleeve can be made to operate, even axle sleeve generation free-runing operation, also can reduce friction to a certain extent, avoid frictional loss.
In another embodiment, the cross section of described oil groove 3 is trapezium structure, strengthens lubrication effect.
In another embodiment, described oil groove 3 arranges in the shape of a spiral.
The utility model structure is simple, good lubrication effect is had between axle sleeve and rotating shaft, wear-resistant paint effectively can strengthen the rub proofness of axle sleeve, improve wear resistance and the rub resistance of axle sleeve, even if axle sleeve generation free-runing operation, also can sustain the frictional loss that axle sleeve causes because of idle running, extend its working life, be worthy to be popularized.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model description to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present utility model.
