The advantage: when firstly fundamentally has prevented the immersed pump operation, the produced violent vibration of its pump well casing way, the weak point of having avoided the background art to exist has gained unexpected technological effect, secondly, simple structure, practicality, long service life.
Description
Technical field
The utility model relate to a kind of can either the sump pump of the elimination type effectively well conduit high vibration of giving birth to when immersed pump runs, have again that structure is simple, practical, the large-sized storage tank immersed pump vibration damping equipment of long service life, belong to vibration damping equipment and manufacture field.
Background technique
In large-sized storage tank, the magna pump well casing of the immersed pump on urceolus top is led to from inner core top, when immersed pump runs, because this pump sump pipeline can produce high vibration, not only can not ensure that immersed pump normally runs for a long time in the absence of a vibration-reducing device, and likely cause the drawing crack of tank deck weld seam.
Model utility content
Purpose of design: avoid the deficiency in background technique, design a kind of can either the sump pump of the elimination type effectively well conduit high vibration of giving birth to when immersed pump runs, have again that structure is simple, practical, the large-sized storage tank immersed pump vibration damping equipment of long service life.
Design proposal: in order to realize above-mentioned purpose of design.1, the utility model adopts and adopts elastomeric vibration isolator to eliminate the design affected large-sized storage tank tank deck outward at large pump sump pipeline, is one of technical characteristics of the present utility model.The object of such design is: because six elastomeric vibration isolator are equidistantly contacted with the pump sump pipeline in storage tank by fastening piece by the utility model, when immersed pump runs, its pump sump pipeline produces high vibration by elastomeric vibration isolator, large-sized storage tank tank deck cannot be delivered to, avoid the destruction to large-sized storage tank tank deck weld seam.2, adopting wire rope to make the design of elastomeric vibration isolator, is technical characteristics two of the present utility model.The object of such design is: the ductility due to wire rope is greatly high other elastic material, thus its conductivity is significantly less than other elastic material, when with its vibration-absorbing material as elastomeric vibration isolator, it can meet rigid support front wire rope positioning plate and the requirement of rear wire rope positioning plate, thus make front wire rope positioning plate both keep relative with rear wire rope positioning plate, keep again apart, when immersed pump can be stoped again to run simultaneously, its pump sump pipeline produce the transmission of high vibration, thus beyond thought damping effect is played to the pump sump pipeline of immersed pump, prevent the high vibration of immersed pump pump sump pipeline, fundamentally avoid the deficiency that background technique exists.3, the design of elastomeric vibration isolator and pump sump pipe pad plate 13 Spielpassung is technical characteristics three of the present utility model.The object of such design is: six elastomeric vibration isolator are equivalent to six and promote and handrail, it can elastic rebound to make on pump sump pipeline pump sump pipe pad plate and its be Spielpassung, stop vibration passing, pump sump pipeline can be made again to keep standing opposite, prevent its to while lodging, thus reach gap vibration isolation and combine with wire rope vibration isolation, effectively prevent the transmission of pump sump pipe vibration.
Technological scheme: a kind of large-sized storage tank immersed pump vibration damping equipment, is made up of base plate, H profile steel I, H profile steel II, outer girth sheets, gusset II, interior girth sheets and elastomeric vibration isolator; The angle of H profile steel I, H profile steel II opposite end weld is greater than 90 degree and to be welded on the base plate of H profile steel I lower end surface vertical with H profile steel I end face, be welded on the outer girth sheets of H profile steel II end face, gusset II and interior girth sheets and be welded into annular brace ring and outer girth sheets in annular brace ring welds with H profile steel II end face, the interior girth sheets in annular brace ring is coordinated with pump sump pipe pad sheet separation by connecting plate, elastomeric vibration isolator.
The utility model is compared with background technique, and one is when fundamentally preventing immersed pump to run, its pump sump high vibration that pipeline produces, and avoids the deficiency that background technique exists, achieves beyond thought technique effect; Two is that structure is simple, practical, long service life.
