Abstract
The utility model discloses a pumping non-contact bearing comprising a pump body (3) and a pump shaft (8). The pump body (3) is fixedly provided with a bearing body (4) which is internally provided with a first permanent magnetic cylinder (10); the pump shaft (8) is fixedly provided with a shaft sleeve (2) which is internally provided with a second permanent magnetic cylinder (9); and the first permanent magnetic cylinder (10) and the second permanent magnetic cylinder (9) are corresponding in the position, are concentric and have the same magnetic pole. In the utility model, the pump can be started in a dry way without cooling and lubricating during operation as the bearing is contactless, and the pumping medium can be directly cooled and lubricated as the sliding bearing of various waterpumps for safe and reliable operation, thereby having wide application prospect and promotional value.
Description
Technical field
The utility model relates to a kind of bearing, particularly relates to a kind of Sliding bearing for pump.
Background technique
Water pump generally adopts the radial support of sliding bearing as pump, the material that sliding bearing adopts is generally rubber or non-ferrous alloy, though the bearing made from these materials also can use the regular hour, but these bearings all are the contact type bearings, there is contact that friction must be arranged, have the friction must consumed power, bearing also can be worn very soon simultaneously; And when the water pump conveying contains the iron oxide severe edema due to hypofunction of the spleen of sand water (as Huanghe water) or Iron And Steel Plant, because granule content is bigger, particle is harder, even the flushing of external clear water and lubricated (can't external clear water under a lot of situations, as the sliding bearing in the middle of the self-balance type multistage pump), sliding bearing also can rapid wearing, causes the water pump fault, influences safe operation.
The model utility content
Technical problem to be solved in the utility model provide a kind of when carrying all kinds of medium the life-span long, do not need external clear water flushing and lubricated, conserve water resource, improve the pump contactless bearing of pump efficiency.
In order to solve the problems of the technologies described above, the pump that the utility model provides contactless bearing, comprise the pump housing, pump shaft, bearing support and axle sleeve, described bearing support is fixed on the described pump housing, described bearing support is built-in with the first permanent magnetism magnetic cylinder, described axle sleeve is fixed on the described pump shaft, and described axle sleeve is built-in with the second permanent magnetism magnetic cylinder, the described first permanent magnetism magnetic cylinder and the second permanent magnetism magnetic cylinder position correspondence, with one heart and magnetic pole identical.
The protective layer of the first permanent magnetism magnetic inside wall of cylinder that described bearing support is built-in is thinner, and its thickness is at 1mm.
Protective layer at the first built-in permanent magnetism magnetic cylinder outer wall of described axle sleeve is thinner, and its thickness is at 1mm.
The described bearing support and the described pump housing adopt Spielpassung, overlap with the center of the pump housing with the center that guarantees the permanent magnetism magnetic cylinder in the described bearing support.
Described axle sleeve and described pump shaft adopt Spielpassung, overlap with the center of pump shaft with the center that guarantees the permanent magnetism magnetic cylinder in the described axle sleeve.
Gap between described bearing support internal diameter and the described axle sleeve external diameter guarantees at 0.1～0.2mm.
Adopt the pump contactless bearing of technique scheme, compared with prior art, have following advantage:
1, because the interaction between the two magnetic cylinders, square being inversely proportional to of the distance between magnetic force and two magnets makes bearing support and axle sleeve remain contactless state, so both improved the efficient of pump, prolonged the working life of bearing again.
2, because the interaction between the two magnetic cylinders, square being inversely proportional to of the distance between magnetic force and two magnets makes pump shaft all the time in the rotation of the center of the pump housing, and this bearing has the absorbing effect, therefore uses the pump of this bearing, and vibration, noise are little, operate steadily reliably.
3, pump can be done startup, does not need external clear water flushing and lubricated, and the conserve water resource is saved operating cost.
In sum, the utility model is a kind of rational in infrastructure, and reliable when carrying all kinds of medium, the life-span is long, improves pump efficiency, reduces noise, saves and safeguards and the pump contactless bearing of operating cost.
Description of drawings
Fig. 1 is pump contactless bearing structure figure.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Referring to Fig. 1, on the pump housing 3, be fixed with bearing support 4, bearing support 4 adopts Spielpassung with the pump housing 3, and fix with screw 6, be built-in with the first permanent magnetism magnetic cylinder of making by neodymium iron boron 10 at bearing support 4, should guarantee during making that the first permanent magnetism magnetic cylinder, 10 centers are consistent with bearing support 4 centers, the protective layer of the first permanent magnetism magnetic cylinder, 10 inwalls that bearing support 4 is built-in is thinner, and its thickness is at 1mm; On pump shaft 8, be fixed with axle sleeve 2, axle sleeve 2 adopts Spielpassung with pump shaft 8, axially locating of axle sleeve 2 by first impeller 1 and second impeller 7, axle sleeve 2 is built-in with the second permanent magnetism magnetic cylinder of being made by neodymium iron boron 9, the first permanent magnetism magnetic cylinder, 10 magnetic poles identical (be all the N utmost point or be all the S utmost point) in the second permanent magnetism magnetic cylinder 9 and the bearing support 4, should guarantee during making that the second permanent magnetism magnetic cylinder, 9 centers are consistent with axle sleeve 2 centers, the protective layer of the second permanent magnetism magnetic cylinder, 9 outer walls that axle sleeve 2 is built-in is thinner, and its thickness is at 1mm; Bearing support 4 forms the contactless bearing with axle sleeve 2, and the gap between bearing support 4 internal diameters and axle sleeve 2 external diameters is played the radial support effect at 0.1～0.2mm to pump.
The utility model bearing, non-contact does not have friction, has the absorbing effect, and water pump can be done startup, and the available medium of pumping in service is cooling and lubricated directly, and it is reliable to operate steadily, and is with a wide range of applications and promotional value.
Personnel in the present technique field should be realized that, the foregoing description is not with this novel qualification of opposing, as long as in this novel connotation scope, any the foregoing description technique variation, flexible program are not all exceeded protection domain of the present utility model.
