Abstract
The utility model provides a kind of sealing structure of stator, is provided with impeller in pump the tip of the axis, impeller is located at the end water inlet of the pump housing, and the end water inlet of the pump housing is provided with protecgulum, and the stator of impeller is between protecgulum and the pump housing, it is characterised in that：Annular groove is offered on stator bottom surface of the stator towards the pump housing, O-ring seal is embedded in groove, O-ring seal contact is on the pump housing.The utility model is simple in construction, easy to use；The leakage face of stator bottom surface is sealed under the mutual fastening effect of the pump housing and protecgulum by O-ring seal, makes the stress equalization of stator, pump discharge is stable, and it is stable to pump out fluid pressure.
Description
Technical field
The utility model belongs to a kind of structure of fluid pump, more particularly to a kind of sealing structure of stator.
Background technology
As shown in Figure 1 and Figure 2, fluid pump is provided with impeller 2 in the end of pump shaft 100, and the end that impeller 2 is located at the pump housing 5 is entered
At the mouth of a river, the end water inlet of the pump housing 5 is installed with protecgulum 3, and the stator 4 of impeller 2 is between protecgulum 3 and the pump housing 5.
Impeller 2 produces centrifugal force after Electric-motor driven pumps axle 100 rotates, by guiding gutter 1 of the liquid through stator 4 from pump
Interior A is sent to pump discharge B directions.
But seepage may occur towards the position of stator bottom surface 7 of the pump housing 5, liquid in stator 4, seepage can cause stator 4
Force unbalance, pump discharge are unstable, pump out fluid pressure decline etc. adverse consequences.
Utility model content
The utility model provides a kind of sealing structure of stator, the purpose is to solve the shortcomings that prior art is present, reduces
The harmful effect that liquid leakage is brought.
Technical scheme is used by the utility model solves its technical problem：
A kind of sealing structure of stator, impeller being installed in pump the tip of the axis, impeller is located at the end water inlet of the pump housing,
The end water inlet of the pump housing is provided with protecgulum, and the stator of impeller is between protecgulum and the pump housing, it is characterised in that：In stator court
Annular groove is offered on to the stator bottom surface of the pump housing, O-ring seal is embedded in groove, O-ring seal contact is on the pump housing.
It is of the present utility model to be beneficial in that：
The utility model is simple in construction, easy to use；By O-ring seal under the mutual fastening effect of the pump housing and protecgulum
The leakage face of stator bottom surface is sealed, makes the stress equalization of stator, pump discharge is stable, and it is stable to pump out fluid pressure.
Brief description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is the utility model blade wheel structure figure；
Fig. 2 is the C-C sectional views of Fig. 1 under prior art；
Fig. 3 is the utility model guide vane section sectional view；
Fig. 4 is the C-C sectional views of Fig. 1 under the utility model.
Embodiment
In order to illustrate more clearly of the technical solution of the utility model, the required accompanying drawing used in description will be made below
Simply introduce, it should be apparent that, drawings in the following description are only some embodiments of the utility model, for this area
For those of ordinary skill, on the premise of not paying creative work, other implement can also be obtained according to these accompanying drawings
Example.
As shown in Fig. 1, Fig. 3, Fig. 4, the utility model fluid pump is provided with impeller 2,2, impeller in the end of pump shaft 100
In the end water inlet of the pump housing 5, the end water inlet of the pump housing 5 is installed with protecgulum 3, and the stator 4 of impeller 2 is located at protecgulum
Between 3 and the pump housing 5.
Improvement of the present utility model is, annular groove 9 is offered on stator bottom surface 7 of the stator 4 towards the pump housing 5, recessed
O-ring seal 8 is embedded in groove 9, after installation, due to the pump housing 5 and the mutual fastening effect of protecgulum 3, O-ring seal contact is in the pump housing
On 5.
So, the pump liquid leached surface of the stator bottom surface 7 in pump between A to pump discharge B is sealed.
So as to liquid, only from the guiding gutter 1 of stator 4, A is sent to pump discharge B directions out of pump, will not reveal, the stress of stator
Equilibrium, pump discharge is stable, and it is stable to pump out fluid pressure.
Each embodiment is described by the way of progressive in this specification, what each embodiment stressed be and other
The difference of embodiment, between each embodiment identical similar portion mutually referring to.To the upper of the disclosed embodiments
State bright, professional and technical personnel in the field is realized or using the utility model.A variety of modifications pair to these embodiments
It will be apparent for those skilled in the art, generic principles defined herein can not depart from this reality
In the case of with new spirit or scope, realize in other embodiments.Therefore, the utility model is not intended to be limited to this
These embodiments shown in text, and it is to fit to the most wide scope consistent with principles disclosed herein and features of novelty.
