Abstract
An interlinking multi-faceted centrifugal sealing device for a pump comprises a shaft seat, wherein a shaft hole is formed in the shaft seat, and a group of symmetrical blades are arranged on the shaft seat, are flow passage shaped curved blades and are spiral. As the straight blades of the prior art are changed into the flow passage shaped curved blades, an axial pressure into the pump body is formed on the basis of the high pressure generated at the shaft hole, and liquid can not leak from the shaft hole under the pressure, therefore the sealing effect is achieved, the service life of the product is prolonged, the maintenance cost is reduced, and the working efficiency of the water pump is improved.
Description
Technical field
The utility model relates to a kind of mechanism's technical field of sealing technology that belongs to, and relates in particular to a kind of seal arrangement of pump.
Background technique
The sealability of water pump is extremely important, if sealability goes wrong, defectives such as run, drip, leak can occur, influences the working efficiency of water pump, and the inoperable phenomenon of water pump appears in serious meeting.Seal arrangement between water pump body and the water pump spindle adopts mechanical seals such as sealing graphite annulus, seal ring usually, and when water pump operation, friction and wear problem can appear in seal arrangement, make seal arrangement lose efficacy, and need often to repair and change.Be to improve the sealability of water pump, prior art as WFB series water pump, its seal arrangement as shown in Figure 1, it comprises axle bed 1, the axis hole 2 of axle bed 1 band keyway 3, axle bed 1 is provided with the some straight leaf 4 of symmetry.This seal arrangement is fixed on the pump shaft of motor output end, whole in the pump housing, connect with motor cabinet, a pair impeller cover, when pump working, rotation along with motor, the prismatic blade high speed rotating of this seal arrangement high pressure occurs at the prismatic blade place of this seal arrangement, and liquid comes out successfully to arrive pump housing outlet by the leading role of paying impeller cover behind the pump housing from stator.But though because the straight leaf of this seal arrangement plays certain seal action, because that the straight leaf of this seal arrangement gets pressure is not enough, understands some liquid and fail to be convened for lack of a quorum and let out by the gap between axis hole and pump shaft, sealing effect is undesirable.
The model utility content
The utility model is the shortcoming at above-mentioned existence, and good seal performance is provided, and the pump that seal arrangement did not rub, do not have wearing and tearing is with a chain of multiaspect centrifugal seal device.
The technological scheme that technical problem adopted that the utility model solves is:
A kind of pump comprises axle bed with a chain of multiaspect centrifugal seal device, is provided with axis hole in the axle bed, and axle bed is provided with one group of blade of symmetry, it is characterized in that described blade is the curved vane of flow channel type, one group of blade-shaped curl.The prismatic blade of original technology is changed into the curved vane of flow channel type, make it to form one axial pressure in the pump housing on the axis hole place produces the basis of high pressure, liquid can't leak out from axis hole under this pressure, thereby reaches the effect of sealing.Common above-mentioned blade is the 6-10 sheet.
The utility model is applied in the water pump, and seal arrangement does not rub, do not have wearing and tearing in the movement process, and long service life, good sealing effect can replace traditional packing seal, packing_seal, mechanical seal.Effectively reduced in the chemical production field fluid delivery process and produced leakage inflammable, explosive, poisonous, hazardous medium because of seal arrangement life-span weak point.Improved reliability of products, also saved great amount of manpower and material resources, financial resources simultaneously for the user.
The beneficial effects of the utility model are: owing to the prismatic blade of original technology is changed into the curved vane of flow channel type, make it on the basis of axis hole place generation high pressure, to form one axial pressure in the pump housing, liquid can't leak out from axis hole under this pressure, thereby reach the effect of sealing, prolonged the working life of product, reduce maintenance cost, improve the working efficiency of water pump.
Description of drawings
Below in conjunction with drawings and Examples model utility is further specified.
Fig. 1 is the prior art constructions schematic representation.
Fig. 2 is the utility model embodiment's a structural representation.
Among the figure: 1, the curved vane of axle bed 2, axis hole 3, keyway 4, straight leaf 5, flow channel type.
Embodiment
In Fig. 2, a kind of pump comprises axle bed 1 with a chain of multiaspect centrifugal seal device, and the curved vane 5 that the axis hole 2 of axle bed 1 band keyway 3, axle bed 1 are provided with 5, eight flow channel types of curved vane of eight symmetrical flow channel types form helicals.The prismatic blade of original technology is changed into the curved vane 5 of flow channel type, make it to form one axial pressure in the pump housing on the axis hole place produces the basis of high pressure, liquid can't leak out from axis hole under this pressure, thereby reaches the effect of sealing.
Claims (2)
1. a pump comprises axle bed with a chain of multiaspect centrifugal seal device, is provided with axis hole in the axle bed, and axle bed is provided with one group of blade of symmetry, it is characterized in that described blade is the curved vane of flow channel type, one group of blade-shaped curl.
2. a kind of pump according to claim 1 is characterized in that with a chain of multiaspect centrifugal seal device above-mentioned blade is the 6-10 sheet.
