Abstract
The utility model provides a spiral stave cooler's structure for transformer, includes the cooler body, and two even helical coiled passage's spirochaeta is made including rolling up the coiled sheet to the cooler body, and helical coiled passage's upper and lower welding has the wire rod, and foretell wire rod is the square steel. The utility model discloses a square steel replaces original round steel, has reduced the welding seam, and the consumption of welding rod significantly reduces, has reduced the quality hidden danger of welding seepage, the cost is reduced, and improved production efficiency and the appearance is beautifully spent.
Description
Technical field
The utility model belongs to heat-exchange apparatus, relates to a kind of for the oil cooled strong oil-water refrigerating mechanism of transformer.
Background technology
Spiral plate type cooler is a kind of novel application heat-exchange apparatus quite widely, the series of advantages such as heat transfer effect is high, drag losses is little, stable operation is reliable, compact conformation, low price that it has.China begins one's study from the later stage sixties and manufactures and worked out corresponding technical standard, manufacture and use many experiences have been have accumulated, the industrial departments such as petrochemical industry refrigeration, organic chemical industry's food, the pharmacy of dyestuff alkaline, machinery, metallurgy are widely used at present, that domestic initiation has recent two decades history as transformer cooler, effect is excellent, and the extremely strong oil-water cooler of spiral is the helicoid being rolled into two uniform helical ducts by roll bending.Respectively burn-on in head and the tail two of two helical ducts and spirochetal upper and lower and outer rim tangential direction and take over and flange, in two passages, have one to have carrier fluid body (You Heshui) to carry out exchange heat in full reverse flow state respectively.Its film-cooled heat is that the expansion length of two steel plates is multiplied by the wide sum of steel plate.In order to strengthen steel plate rigidity, improve spirochetal critical pressure, on two steel plates same is practised physiognomy, be welded with the spacing column of certain density, so also can increase the disturbance of fluid, increase Reynolds number, improve heat transfer efficiency.
The spiral plate type cooler of transformer of prior art generally includes cooler body, cooler body comprises the helicoid that roll bending rolls into two uniform helical ducts, helical duct be welded with round steel up and down, round steel up and down and roll bending tangent, when round steel welds with roll bending, usually the gap weldering between round steel and roll bending is full, its welding wire consumption is large, and weld time is long, is easily out of shape, easy burn-through roll bending, causes the hidden danger of quality of seepage.In addition due to point cantact between round steel and roll bending, during welding, more difficult location, the roll bending active force instability that round steel is upper and lower, the consumption of welding rod is large, and the roll bending of cooler and round steel are generally stainless steel material in addition, and its weld horizontal requires higher, easily occur welding deformation and welding Seepage, therefore round steel welds the difficulty that the increase that can cause weld seam and welding quality control with roll bending.
Utility model content
The purpose of this utility model is to solve above-mentioned the deficiencies in the prior art, and provide a kind of spiral plate type cooler of transformer structure, its weld seam is little, and welding material expenditure is little, is not easy distortion and occurs Seepage, to improve product quality and production efficiency is low.
The technical scheme that the technical problem that the utility model solves adopts is:
A structure for spiral plate type cooler of transformer, comprises cooler body, and cooler body comprises the helicoid that roll bending rolls into two uniform helical ducts, helical duct be welded with wire rod up and down, it is characterized in that above-mentioned wire rod is square steel.
The utility model adopts square steel to substitute original round steel, and roll bending is close in square steel top and bottom, and square steel side is vertical with roll bending, and when square steel side is welded with roll bending, its weld seam is considerably less, and welding wire consumption is little, is very easy to welding, when welding, is not easy to penetrate roll bending.In addition, because roll bending is close in square steel top and bottom, therefore the passage of roll bending is more even up and down, and the active force being close to the roll bending up and down of square steel is stablized, its consistency is good, and the steel plate both sides of helical duct there will not be metaboly, improve welding quality, improve good looking appearance degree simultaneously.Technical solutions of the utility model weld seam is little, and the consumption of welding rod greatly reduces, and the difficulty that welding quality controls reduces, and improves production efficiency.
During concrete enforcement, above-mentioned coiled sheet is stainless-steel sheet, and above-mentioned square steel is stainless steel square steel.
During concrete enforcement, head and the tail two of above-mentioned two helical ducts, is be located at spirochetal upper and lower and outer rim tangential direction respectively, head and the tail two of two helical ducts is respectively connected with pipeline and flange, is provided with cover plate above cooler.Usual spirochetal upper and lower pipeline is turnover oil pipe, and spirochetal outer rim tangential direction pipeline is water inlet pipe and water outlet pipe.
The beneficial effects of the utility model are: the utility model adopts square steel to substitute original round steel, and decrease weld seam, the consumption of welding rod greatly reduces, and decreases the hidden danger of quality of welding seepage, reduces cost, improve production efficiency and good looking appearance degree.
Embodiment
In fig. 1 and 2, with YSLB0.6-160 spiral plate type cooler of transformer for example.A kind of spiral plate type cooler of transformer of the utility model embodiment, comprise the helicoid that roll bending 1 rolls into two uniform helical ducts, head and the tail two of two helical ducts and spirochetal upper and lower and outer rim tangential direction are respectively connected with pipeline 2 and flange 3, spirochetal upper and lower pipeline 2 is turnover oil pipe, spirochetal outer rim tangential direction pipeline 2 is water inlet pipe and water outlet pipe, cover plate 4 is provided with above cooler, helical duct be welded with stainless steel square steel 5 up and down, coiled sheet 1 is stainless-steel sheet, in order to strengthen the rigidity of steel plate, improve spirochetal critical pressure, roll bending 1 is welded with the spacing column of certain density, so also can increase the disturbance of fluid, increase Reynolds number, improve heat transfer efficiency.
The utility model adopts square steel 5 to substitute original round steel, and roll bending 1 is close in square steel 5 top and bottom, and square steel 5 side is vertical with roll bending 1, when square steel 5 side is welded with roll bending, its weld seam is considerably less, and welding wire consumption is little, be very easy to welding, when welding, be not easy to penetrate roll bending.In addition, because roll bending 1 is close in square steel 5 top and bottom, therefore the passage of roll bending 1 is more even up and down, and the active force being close to the roll bending up and down of square steel 5 is stablized, its consistency is good, and the steel plate both sides of helical duct there will not be metaboly, improve welding quality, improve good looking appearance degree simultaneously.Technical solutions of the utility model weld seam is little, and the consumption of welding rod greatly reduces, and the difficulty that welding quality controls reduces, and improves production efficiency.
Finally, it is also to be noted that what enumerate above is only specific embodiment of the utility model.Obviously, the utility model is not limited to above embodiment, can also have many distortion.All distortion that those of ordinary skill in the art can directly derive from disclosed content of the present utility model or associate, all should think protection range of the present utility model.
