Abstract
The invention discloses a cooler tube plate and cooling tube welding method. A cooler comprises a tube plate provided with a plurality of cooling tube installation holes and cooling tubes inserted in the cooling tube installation holes in the tube plate. The method includes the operation step A that an annular groove is formed around the cooling tube installation holes of the tube plate; the step B that the cooling tubes are installed in the cooling tube installation holes of the tube plate in an expansion joint mode, and ends of the cooling tubes extend out of the end faces of the cooling tube installation holes of the tube plate by 2mm-3mm; the step C that the cooling tubes and the tube plate are connected through argon arc welding without filler metal. Compared with the prior art, the cooler tube plate and cooling tube welding method can solve the problem that as a single welding or expansion joint mode is adopted in connection of a stainless steel tube plate and cooling tubes, a cooler is prone to water leakage.
Description
Technical field
The present invention relates to welding technology field, especially a kind of for the tube sheet of stainless steel and the welding method of cooling tube.
Background technology
Tube sheet and cooling tube are the important partses of cooler, tube sheet generally has expanded joint with the connected mode of cooling tube, weld and expanded and welded tube joint several forms such as use, but for the cooler with vinyl chloride gas compressor, because vinyl chloride gas is corrosive, therefore tube sheet and cooling tube need select tube sheet and the cooling tube of stainless steel.The expanded joint of stainless steel and weldability are all slightly poor, if the tube sheet of stainless steel and cooling tube are selected to be welded to connect, commissure easily cracks and causes water leakage of cooler; Tube sheet and cooling tube and adopt expanded joint mode to be connected, expanded joint is in running easily to be shaken to loosen and leaks, and these all directly have influence on the performance of cooler and even the safe operation of unit.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of tube sheet of cooler and the welding method of cooling tube, use single welding or expanded joint connected mode with the connection of the tube sheet with cooling tube that solve existing stainless steel, easily make the problem of cooler generation drainage.
The technical scheme that technical solution problem of the present invention adopts is: the tube sheet of this cooler and the welding method of cooling tube, cooler comprises the tube sheet being provided with multiple cooling tube installing hole and the cooling tube be inserted in the multiple cooling tube installing hole of described tube sheet, comprises following operating procedure:
A, around the cooling tube installing hole of described tube sheet, open an annular groove, for subsequent use;
B, by expanded joint, described cooling tube to be contained in the cooling tube installing hole of described tube sheet, and to make described cooling tube termination stretch out the cooling tube installing hole end face 2 millimeters ~ 3 millimeters of described tube sheet;
Described cooling tube is connected with described Tube-sheet Welding by C, the argon arc welding using nothing to fill metal.
In the tube sheet of above-mentioned cooler and the welding method technical scheme of cooling tube, technical scheme can also be more specifically: described annular groove width and the degree of depth are 1.5 millimeters, and the distance of the cooling tube installing hole outer wall of described annular groove and described tube sheet is 1.5 millimeters.
Owing to have employed technique scheme, the present invention compared with prior art, the beneficial effect had is: 1, owing to being first connected with tube plate expanded-connecting by cooling tube, again by welding without filling on the argon arc welding of the metal annular groove around tube sheet cooling tube installing hole, make the stainless steel mother liquor of fusing will cool tube hydroforming connection; 2, use groove welding effectively can reduce welding residual stress, make its coverage be contracted within the scope of groove, prevent tube sheet from deforming after welding, increase the service life of cooler.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described:

A, by drilling processing around the cooling tube installing hole of tube sheet 1, open an annular groove, this annular groove width b and degree of depth h is 1.5 millimeters, and the distance of the cooling tube installing hole outer wall of annular groove and tube sheet 1 is 1.5 millimeters; For subsequent use;
B, by expanded joint, cooling tube 2 to be contained in the cooling tube installing hole of described tube sheet, and to make cooling tube 2 termination stretch out the cooling tube installing hole end face 2 millimeters of tube sheet 1;
Cooling tube 2 and tube sheet 1 are welded to connect by C, the argon arc welding using nothing to fill metal.
Embodiment 2:
It comprises following operating procedure:
The cooling tube installing hole end face 3 millimeters of tube sheet 1 is stretched out in cooling tube 2 termination; Other features are identical with embodiment 1.
