Impeller heads on protecgulum and rotated all the time, therefore, under working condition, and protecgulum is also by from the huge active force of impeller, especially
In abnormal cases, such as mixed flow or cavitation, impeller can tempestuously hit protecgulum for pumping, not only produce much noise, influence pump
Performance, meanwhile, can badly damaged impeller and protecgulum.
Existing pump protecgulum adds the mechanical loss of pumping work, reduces the work of pumping without any shock-damping structure
Efficiency.Meanwhile, noise and the vibrations of pumping entrance are considerably increased, are had a greatly reduced quality using pumping life-span and usage experience.
The content of the invention
The purpose of this utility model is that there is provided a kind of simple in construction, easy to use for the drawbacks described above of prior art
Pump protecgulum shock-damping structure.The shock-damping structure of this case can effectively alleviate after tested pumping work when protecgulum suffered by axle thrust,
Hard hit power of the impeller to the it when unbalanced force and cavitation of impeller during mixed flow.The service life of pump is substantially increased, is reduced
Noise and vibrations during pump work, improve the task performance of pumping.
To solve the drawbacks described above of prior art, the technical scheme that the utility model is provided is：A kind of pump protecgulum damping knot
Structure, including pump protecgulum annulus seat, the upper surface of the pump protecgulum annulus seat are provided with an annulus, the edge of the pump protecgulum annulus seat
It is bent up folding the fold shock-damping structure of a U-shaped profile, the lower surface of the pump protecgulum annulus seat is interval with multigroup
Support component for connecting pump protecgulum.
Improved as one kind of the utility model pump protecgulum shock-damping structure, what the support component was correspondingly arranged including two
There is certain gap between support column, two support columns.
Improved as one kind of the utility model pump protecgulum shock-damping structure, the lower end edge correspondence direction of two support columns
90-degree bent, forms a vertical kink, the inside edge extension of pump protecgulum annulus seat described in the upper end edge of the support column,
Formed between an arc extension for playing shock absorbing effect, two arc extensions and be provided with a groove.
Improved as one kind of the utility model pump protecgulum shock-damping structure, the width of the annulus is justified less than the pump protecgulum
The upper plane width of ring seat.
Improved as one kind of the utility model pump protecgulum shock-damping structure, the marginating compartment of the annulus lacks provided with multiple
Mouthful.
Improved as one kind of the utility model pump protecgulum shock-damping structure, the upper level of the fold shock-damping structure is low
In the upper level of pump protecgulum annulus seat.
Compared with prior art, the utility model has the advantages that：The utility model, should in the shock-damping structure of pump front design one
Shock-damping structure upper end sets and sets a pleated structure on the outside of an annulus, annulus, and this pleated structure is fixed on pump protecgulum entrance, can produce and subtract
Shake is acted on.Meanwhile, in three groups of circular arc support columns of annulus bottom design, each group support intercolumniation leaves space, before being secured to
Lid, anti-structure here is performed relative motion with protecgulum or impeller.When can effectively alleviate pumping work after tested using shock-damping structure
When axle thrust suffered by protecgulum, mixed flow when the unbalanced force and cavitation of impeller impeller to its hard hit power.Greatly improve
The service life of pump, noise and vibrations when reducing pump work, improves the task performance of pumping.

Fig. 2 is the utility model reverse side dimensional structure diagram.
Fig. 3 is the utility model front view.
Reference title：1st, pump protecgulum annulus seat 2, annulus 3, fold shock-damping structure 4, support component 5, breach
41st, support column 42, gap 43, kink 44, arc extension 45, groove.
Embodiment
Just the utility model is further described with specific embodiment with reference to the accompanying drawings below, but implementation of the present utility model
Mode is not limited to this.
As shown in Figure 1, Figure 2 and Figure 3, a kind of pump protecgulum shock-damping structure, including pump protecgulum annulus seat 1, pump protecgulum annulus seat 1
Upper surface be provided with an annulus 2, the edge of pump protecgulum annulus seat 1 is bent up folding the fold damping knot of a U-shaped profile
Structure 3, the lower surface of pump protecgulum annulus seat 1 is interval with multigroup support component 4 for being used to connect pump protecgulum.
It is preferred that, support component 4 includes having necessarily between two support columns 41 being correspondingly arranged, two support columns 41
Gap 42.Two support columns 41 for being correspondingly arranged, with certain elasticity, can be connected to before pump when installing connection pump protecgulum
Cover, anti-structure here is performed relative motion with protecgulum or impeller, is connected firmly.Support component 4 uses the good material of elasticity series,
Gap 42 can ensure the deformation space at kink 43, and this ring can be fixed by also having.
It is preferred that, the lower end edge correspondence direction 90-degree bent of two support columns 41, forming one has hanging down for directed force effect
