Description

Large-sized storage tank immersed pump vibration absorber
Technical field
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 Field.
Background technology
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.
Invention content
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 It passs.
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.
