Abstract
The quick assembling method of built-in double tube plate heat exchanger cylinder.Tube sheet is the structure for being built in enclosure interior, and due to the gap very little of tube sheet and housing, the presence of housing ovality and angularity makes suit relatively difficult.The step of present invention built-in double tube plate heat exchanger cylinder suit housing is：Step 1, processing tube sheet diameter of part is smaller 1 ~ 2mm than drawing size, makes its gap between housing；Step 2, left side tube sheet, partition board, right side tube sheet are found successively, forms encasement tube module, then wear heat exchanger tube and tack-weld, it is after spot welding positioning, heat exchanger tube, left side tube sheet, partition board, right side Tube-sheet Welding is secured, and clear up welding bead；Step 3, encasement tube module and housing, bottom argon arc welding welding ensure one side welding with back formation, and welding electrode is completely filled and cover welding.The present invention is used to implement built-in double tube plate heat exchanger cylinder suit.
Description
Technical field：
The present invention relates to an installation processes in the heat exchanger of built-in two-tube harden structure, and in particular to a kind of built-in
The quick assembling method of double tube plate heat exchanger cylinder.
Background technology：
The tube sheet of usual heat exchanger and the form that housing is butt weld, during manufacture, successively standpipe plate, partition board, wear heat exchanger tube, group
Dress up piping, then cover casing, the technological process of this set of maturation enable product efficiently production into；Also a kind of heat exchanger, pipe
Plate is the structure for being built in enclosure interior, and due to the gap very little of tube sheet and housing, the presence of housing ovality and angularity makes
Suit can not be realized.
At this moment Normal practice is to will be close to the both sides cylinder of tube sheet to block respectively in industry, dresses up pipe with tube sheet part respectively
Plate component after one end tube sheet component wears heat exchanger tube, then closes up other end tube sheet component, and this assembly method has been significantly greatly increased another
End pipe plate will ensure the difficulty that the concentric fits in each hole are closed up, and need to make tooling and lengthen any special measures reality such as positioning heat exchanger tube
In place, the even blind risk worn heat exchanger tube, while can not also realize tube-tube plate whole automatic welding of some of existing tube sheet.
Invention content：
The object of the present invention is to provide a kind of quick assembling methods of built-in double tube plate heat exchanger cylinder, can make this built-in
The cumbersome manufacture of formula tubular sheet heat exchanger can become simple and convenient as the conventional structure of heat exchanger, greatly improve efficiency.
Above-mentioned purpose is realized by following technical scheme：
A kind of quick assembling method of built-in double tube plate heat exchanger cylinder, step are as follows：
Step 1, processing left side tube sheet, the diameter of part of right side tube sheet are smaller 1 ~ 2mm than drawing basic size, make it between housing
Gap is unilateral to reach 3 ~ 4mm；
Step 2, left side tube sheet, partition board, right side tube sheet are found successively, forms encasement tube module, then wear heat exchanger tube and anchor point
Weldering, it is after spot welding positioning, heat exchanger tube, left side tube sheet, partition board, right side Tube-sheet Welding is secured, and clear up welding bead；
Step 3, encasement tube module and housing, bottom argon arc welding welding, ensure one side welding with back formation, and welding electrode is completely filled simultaneously
Cover welding carries out carrying out flaw detection；Subsequent step is identical with conventional structure heat exchanger.
The quick assembling method of the built-in double tube plate heat exchanger cylinder, the housing is tubular construction, described
Housing both ends pressed respectively equipped with left side tube sheet, right side tube sheet, position is welded with heat exchanger tube among the housing both sides, described
Heat exchanger tube and one group of partition board weld, the partition board parallel arrangement described in one group.
Advantageous effect：
It is used to manufacture built-in tube sheet 1. the present invention is one kind（Especially two-tube harden structure）During heat exchanger, enable piping and housing
A kind of convenient method being smoothly set with, this method of use can make the cumbersome manufacture of this built-in type tube sheet heat exchanger can be with
Become simple and convenient as the conventional structure of heat exchanger, greatly improve working efficiency.
The present invention is according to the practical specification of cylinder, when processing tube sheet part, and by left and right side tube sheet diameter processing dimension ratio
Small 1 ~ the 2mm of basic size of detail of design increases the fit-up gap of left and right side tube sheet and housing, built-in double convenient for being set with
Tubular sheet heat exchanger cylinder, the both sides for avoiding Normal practice are cut into pipe nipple respectively close to the cylinder of tube sheet, form 1 He of tube sheet component
Tube sheet component 2 after one end tube sheet component wears heat exchanger tube, then closes up other end tube sheet component, which has been significantly greatly increased separately
One end tube sheet will ensure the difficulty that the concentric fits in each hole are closed up, and wearing heat exchanger tube needs fabricating tools and lengthen positioning heat exchanger tube etc.
Any special measures, therefore say that the application reduces manufacture difficulty, production efficiency is improved, ensure that heat exchanger tube is smoothly set with housing.
The structure type that the present invention uses can realize that housing is smoothly set with piping, avoid it is blind wear heat exchanger tube, cause to pacify
Time-consuming disadvantage during dress, at the same also be able to realize tube-tube plate whole automatic welding, have it is easy for installation, greatly reduce system
Difficulty is made, production is improved into efficiency, saves the advantages that tooling more saves a large amount of working hours simultaneously.
Description of the drawings：
Attached drawing 1 is the structure diagram of the present invention.
Attached drawing 2 is conventional internal formula double tube plate heat exchanger cylinder sleeve structure.
