It is that example is elaborated that this specific embodiment twines the location poling in conjunction with the heat exchanger tube that with the diameter is the 19mm specification.
As shown in Figure 1, a kind of winding tube bank positioner comprises left tube sheet assembly 1, right tube sheet assembly 2 and central tube, and central tube is divided into outer central tube 3 and interior central tube 4, one end of outer central tube 3 links to each other with left tube sheet assembly 1, and an end of interior central tube 4 links to each other with right tube sheet assembly 2; The outer diameter of interior central tube 4 is less than the inner diameter of outer central tube 3, and interior central tube 4 is nested in the outer central tube 3.
The interim dress is welded with moment of torsion transmission tube at the back side of left tube sheet assembly 1, the removal after winding tube bank coiling finishes of this moment of torsion transmission tube.Tube sheet and central tube are welded to connect.
The external diameter of interior central tube 4 is slightly less than the internal diameter of outer central tube 3, and central tube 4 is nested in to constitute in the outer central tube 3 and is slidingly connected in making, thereby makes that the relative position between the tube sheet of central tube two ends is unfixing, and right tube sheet assembly 2 can be along central tube axis direction move left and right.
Also comprise dividing plate 5, as shown in Figure 2, described dividing plate 5 is the metallic plate of annular, endwisely slips on the central tube 4 in being enclosed within; Described dividing plate 5 has in layer circular port at annulus around the center of circle.
Dividing plate 5 can slide at interior central tube 4, also can move under the drive of interior central tube 4.
Also comprise floral disc assembly 6, as shown in Figure 3, formed by several floral discs, be used for suit and be fixed on outer central tube 3; Floral disc has semi-circular recesses, and its shape is with identical along the come multi-layer annular dish that forms of dividing plate 5 each layer open circles heartcut by the identical part of dividing plate 5.
Described floral disc assembly 6 each layer floral disc are split into two halves along its center line.
Described floral disc assembly 6 is split into two halves except all the other each layer floral discs of innermost layer floral disc along its center line.
Floral disc assembly 6 (among Fig. 3 from left to right) from inside to outside is that ground floor floral disc 6-1, second layer floral disc 6-2, the 3rd layer of floral disc 6-3, the 4th layer of floral disc 6-4, layer 5 floral disc 6-5, layer 6 floral disc 6-6, layer 7 floral disc 6-7, the 8th layer of floral disc 6-8 form.The right-hand member of central tube 3 dress is welded with ground floor floral disc 6-1 outside.
Make in the tube bank process, after having twined every layer of heat exchanger tube, elder generation is the poling plate not.When carrying out every heat exchanger tube ending, can utilize each layer floral disc (6-1,6-2 ...) and dividing plate 5 fix heat exchanger tube, all each layer heat exchanger tubes after all coiling finishes again integral body cover the right-hand member tube sheet.Its specific operation process is as follows.
As shown in Figure 4 and Figure 5, the positioning action method is twined in a kind of installation of twining the tube bank positioner:
A, the ground floor floral disc 6-1 of floral disc assembly 6 is installed in the other end of outer central tube 3;
B, the interior central tube 4 that will be with dividing plate 5 and outer central tube 3 suits form and flexibly connect, and be placed on and twine beginning coiling ground floor heat exchanger tube and location on the frock, every heat exchanger tube of this layer snapped in the corresponding recesses on the ground floor floral disc 6-1, pass the corresponding aperture on the dividing plate 5 again, realize the heat exchanger tube location;
Behind the ground floor heat exchanger tube on the intact tube sheet of c, coiling, the two halves of second layer floral disc 6-2 merged be stuck on the ground floor heat exchanger tube, and two parts are welded beginning coiling second layer heat exchanger tube and location;
D, repeating step c finish the coiling of each layer heat exchanger tube;
E, with right tube sheet assembly 2 left tube sheet assembly 1 direction move, from the internal layer to the skin, allow each layer heat exchanger tube cover be through in the pore of each layer correspondence on the right tube sheet assembly 2 successively, and continue left that tube sheet assembly 1 direction moves, make dividing plate 5 pass right tube sheet assembly 2 near floral disc assemblies 6 to guarantee heat exchanger tube;
F, the unnecessary length of stretching out the heat exchanger tube of right tube sheet assembly 2 with pipe end Slicking apparatus excision.
Owing to after heat exchanger tube passes right tube sheet assembly 2, the design requirement that welds with right tube sheet assembly 2 is arranged, so heat exchanger tube should stretch out right tube sheet assembly 2 certain-lengths (as 1 to 2 centimetre length) to satisfy the welding demand.
Ground floor floral disc (6-1) is welded outside on the central tube 3 among the wherein said step a.
The concrete grammar step of wherein said each layer of coiling heat exchanger tube and location is: every coiling finishes a heat exchanger tube, after the heat exchanger tube ending, be stuck in earlier in the half slot of floral disc, penetrate the ending location of finishing the heat exchanger tube afterbody in the corresponding aperture of dividing plate 5 again, so repeatedly, finish the location of each layer heat exchanger tube afterbody.
With third and fourth ... layer floral disc (6-3,6-4 ...) two halves merge be stuck in second and third ... on the layer heat exchanger tube, and two parts of each layer floral disc are welded.Be stuck in the half slot of each layer floral disc after each root heat exchanger tube ending with each layer, penetrate again in the corresponding aperture of dividing plate 5 each layers, finish the ending location of each root heat exchanger tube afterbody of each layer.
Each layer of heat exchanger tube tail end length in reserve progressively increases from the skin to the internal layer, increases length and is not less than one times dividing plate 5 thickness.
When covering dividing plate 5, around pipe, dividing plate 5 advances left gradually, allows heat exchanger tube successively overlap and is through in the dividing plate 5 corresponding pores along with successively.When covering tube sheet, also be successively to cover from inside to outside, encounter problems convenient the processing when covering.
