Large-sized storage tank immersed pump vibration absorber
The present invention relates to it is a kind of can either effectively elimination type sump pump well conduit given birth to when immersed pump is run it is violent
Vibration, and there is large-sized storage tank immersed pump vibration absorber simple in structure, practical, with long service life, belong to vibration absorber manufacture
In large-sized storage tank, the mammoth pump well casing of the immersed pump on outer barrel top is led to from inner cylinder top, when immersed pump is run,
Since the pump sump pipeline will produce high vibration, in the absence of a vibration-reducing device not only it cannot be guaranteed that immersed pump is normal for a long time
Operation, and it is also possible to lead to tank deck weld seam drawing crack.
Purpose of design：Avoid the shortcoming in background technology, design one kind can either effectively elimination type storage tank pump sump
The high vibration that pipeline is given birth to when immersed pump is run, and with the latent liquid of large-sized storage tank simple in structure, practical, with long service life
Pump vibration absorber.
Design scheme：In order to realize above-mentioned purpose of design.1, the present invention is used uses elastomeric isolation outside big pump sump pipeline
Device eliminates the design influenced on large-sized storage tank tank deck, is one of the technical characteristic of the present invention.The purpose designed in this way is：Due to
Six elastomeric vibration isolators are equidistantly in contact with the pump sump pipeline in storage tank by the present invention by fastener, when immersed pump is run
When, pump sump pipeline generates high vibration by elastomeric vibration isolator, can not be transmitted to large-sized storage tank tank deck, avoid to large-sized storage tank
The destruction of tank deck weld seam.2, the design that elastomeric vibration isolator is made of steel wire rope is the two of the technical characteristic of the present invention.It sets in this way
The purpose of meter is：Due to the significantly high other elastic materials of the flexibility of steel wire rope, thus its conductibility be significantly less than it is other
Elastic material, when using its vibration-absorbing material as elastomeric vibration isolator, it can meet before rigid support steel wire rope positioning plate and
Steel wire rope positioning plate requirement afterwards to make preceding steel wire rope positioning plate and rear steel wire rope positioning plate not only keep opposite, but also is kept apart,
When immersed pump can be prevented to run again simultaneously, the transmission of high vibration produced by pump sump pipeline, to the pump sump pipe to immersed pump
Play unexpected damping effect in road, it is therefore prevented that the high vibration of immersed pump pump sump pipeline fundamentally avoids background technology
Existing shortcoming.3, the design of 13 clearance fit of elastomeric vibration isolator and pump sump pipe pad plate, be the present invention technical characteristic it
Three.The purpose designed in this way is：Six elastomeric vibration isolators be equivalent to six push and handrail, it can elastic rebound make pump
Pump sump pipe pad plate transmits in clearance fit, prevention vibration with it, and pump sump pipeline can be made to keep standing opposite on well conduit, prevents
It lodges to one side, is combined with steel wire rope vibration isolation to reach gap vibration isolation, effectively prevents the biography of pump sump pipe vibration
Technical solution：A kind of large-sized storage tank immersed pump vibration absorber, by bottom plate, H profile steel I, H profile steel II, outer girth sheets, muscle
Plate II, interior girth sheets and elastomeric vibration isolator are constituted；H profile steel I, H profile steel II opposite end welds angle be more than 90 degree and welding
Bottom plate in the lower faces H profile steel I is vertical with the end faces H profile steel I, is welded on the outer girth sheets, gusset II and interior girth sheets of the end faces H profile steel II
The outer girth sheets being welded into annular brace ring and annular brace ring is welded with the end faces H profile steel II, the interior girth sheets in annular brace ring
Coordinated by connecting plate, elastomeric vibration isolator and pump sump pipe pad sheet separation.
Compared with the background technology, the present invention, first, when fundamentally immersed pump being prevented to run, produced by pump sump pipeline
High vibration avoids shortcoming existing for background technology, achieves unexpected technique effect；Second is that simple in structure,
Practicality, service life are long.

Specific implementation mode
Embodiment 1：With reference to attached drawing 1-3.A kind of large-sized storage tank immersed pump vibration absorber, by bottom plate 1, H profile steel I 2, H
Shaped steel II 3, outer girth sheets 5, gusset II 6, interior girth sheets 7 and elastomeric vibration isolator are constituted；H profile steel I 2,3 opposite ends of H profile steel II
The angle of weld be more than 90 degree and be welded on 2 lower faces H profile steel I bottom plate 1 it is vertical with 2 end faces H profile steel I, be welded on H-type
Outer girth sheets 5, gusset II6 and the interior girth sheets 7 of 3 end faces steel II be welded into outer girth sheets 5 in annular brace ring and annular brace ring with
3 end faces H profile steel II are welded, and the interior girth sheets 7 in annular brace ring passes through between connecting plate 8, elastomeric vibration isolator and pump sump pipe pad plate 13
Gap coordinates, and connecting plate 8 is connect by bolt 9, nut 10, washer 11 with interior girth sheets 7.The elastomeric vibration isolator 12 is by preceding steel wire rope
Positioning plate 121, steel wire rope 122 and rear steel wire rope positioning plate 123 are constituted, and steel wire rope 122 from bottom to top or from top to bottom wear by spiral
Cross preceding steel wire rope positioning plate 121 and steel wire location hole in rear steel wire rope positioning plate 123 and with preceding steel wire rope positioning plate 121 and after
The elastomeric isolation that steel wire rope positioning plate 123 constitutes preceding steel wire rope positioning plate 121 and the compression of rear 123 spacing of steel wire rope positioning plate can be changed
Device.The preceding steel wire rope positioning plate 121 and rear steel wire rope positioning plate 123 are for split structure and by positioning groove plate and pressing plate structure
At pressing plate is pressed on frid and constitutes steel wire location hole.The connecting plate is linked into an integrated entity with isolator by fastener.It is described
Isolator 12 is six and equidistant annular spread, and the technique system processed prior art is not described herein herein.
Embodiment 2：On the basis of embodiment 1, there is gusset I 4 in the annular brace ring.
It is to be understood that：Although above-described embodiment contrasts detailed verbal description to the present invention, these
Verbal description only describes the simple text of mentality of designing of the present invention, rather than to the limitation of invention mentality of designing, it is any not
Combination, increase or modification beyond mentality of designing of the present invention, each falls in protection scope of the present invention.
