Abstract
The invention discloses a processing technique for a liner of a jacket of a solar water heater, which comprises the following steps: welding straight slits on an inner cylinder (1) after rolling the inner cylinder (1) to roundness; assembling end enclosures (4) on two sides of the inner cylinder (1), and welding circular seams between the inner cylinder (1) and the end enclosures (4); assembling hoops (3) on the end enclosures on the two sides, and welding circular seams between the hoops (3) and the end enclosures (4); performing air tightness tests; assembling an outer cylinder (2), and welding circular seams between the outer cylinder (2) and the hoops (3); performing borax film treatment on an interlayer between the inner cylinder (1) and the outer cylinder (2); and performing enamel sintering on the inner side of the inner cylinder (1). The processing technique can process a semi-finished product of the liner only from a weld line to an enamel line and reduce product transportation and reciprocating between workshop sections so as to improve the production efficiency.
Description
Technical field
The present invention relates to a kind of solar water heater's water tank, especially relate to a kind of processing technology that is used for liner of jacket of solar water heater.
Background technology
Along with popularizing of solar water heater, the user is more and more higher to the functional requirement of water heater.Solar water heater's water tank of prior art, its structure generally comprises shell, water inlet pipe and water outlet pipe, heat exchanger and inner bag.The water tank that has adopts liner of jacket to carry out heat exchange, comprises internal layer cylinder and outer layer barrel, also can sintering enamelled layer in the inboard of internal layer cylinder, and to prolong the service life of water tank.At present, existing technology all is to weld earlier internal layer cylinder, end socket, hoop on sealing wire, again behind the inboard sintering enamelled layer with internal layer cylinder on the enamel line, get back to welding assembling outer layer barrel on the sealing wire again, so that product is repeatedly carried, and causes workshop section reciprocal, has influenced the raising of production efficiency.In addition, the high temperature during the welding outer layer barrel also can damage the internal layer cylinder inboard enamel layer of sintering, influences product quality.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of product that can reduce and carries number of times, reduces the reciprocal processing technology that is used for liner of jacket of solar water heater of workshop section.
Technical problem to be solved by this invention is achieved by the following technical solution: processing step is as follows: after (1) rolls up circle with internal layer cylinder, and the vertical masonry joint on the welding internal layer cylinder; (2) end socket of assembling internal layer cylinder both sides, the circumferential weld between welding internal layer cylinder and end socket; (3) hoop on the end socket of assembling both sides, the circumferential weld between welding hoop and end socket; (4) carry out air tightness test; (5) assembling outer layer barrel, the circumferential weld between welding outer layer barrel and hoop; (6) interlayer between internal layer cylinder and the outer layer barrel being carried out the borax film handles; (7) the enamel sintering is carried out in the inboard of internal layer cylinder, form enamel layer; (8) carry out air tightness test.
The invention has the beneficial effects as follows:
1, the high-temperature damage internal layer cylinder inboard of original technology when the welding outer layer barrel enamel layer of sintering can be prevented, the quality of enamel layer can be guaranteed;
2, only need just the inner bag semi-finished product can be processed into, the product carrying can be reduced by sealing wire to the enamel line, reciprocal between minimizing workshop section, thus can enhance productivity;
3, before sintering enamelled, carry out interlayer borax film and handle, can prevent the oxide skin phenomenon that metal produces in the interlayer when high-temperature tubring.
Description of drawings
The present invention is described further below in conjunction with accompanying drawing:
Accompanying drawing is depicted as the structural representation of processes product of the present invention
The specific embodiment
Be appreciated that by accompanying drawing this is used for the processing technology of liner of jacket of solar water heater, processing step is as follows: after (1) rolls up circle with internal layer cylinder 1, and the vertical masonry joint on the welding internal layer cylinder 1; (2) end socket 4 of assembling internal layer cylinder 1 both sides, the circumferential weld that welding internal layer cylinder 1 and end socket are 4; (3) hoop 3 on the end socket of assembling both sides, the circumferential weld that welding hoop 3 and end socket are 4; (4) carry out air tightness test; (5) assembling outer layer barrel 2, the circumferential weld that welding outer layer barrel 2 and hoop are 3; (6) interlayer between internal layer cylinder 1 and the outer layer barrel 2 being carried out the borax film handles; (7) the enamel sintering is carried out in the inboard of internal layer cylinder 1, form enamel layer; (8) carry out air tightness test.The present invention is after outer layer barrel welding assembling, the interlayer between internal layer cylinder and the outer layer barrel is carried out the borax film handle, and is just sintering enamelled to the internal layer cylinder inboard at last.
Claims (1)
1, a kind of processing technology that is used for liner of jacket of solar water heater is characterized in that processing step is as follows:
(1) with behind the internal layer cylinder volume circle, the vertical masonry joint on the welding internal layer cylinder;
(2) end socket of assembling internal layer cylinder both sides, the circumferential weld between welding internal layer cylinder and end socket;
(3) hoop on the end socket of assembling both sides, the circumferential weld between welding hoop and end socket;
(4) carry out air tightness test;
(5) assembling outer layer barrel, the circumferential weld between welding outer layer barrel and hoop;
(6) interlayer between internal layer cylinder and the outer layer barrel being carried out the borax film handles;
(7) the enamel sintering is carried out in the inboard of internal layer cylinder, form enamel layer;
(8) carry out air tightness test.
