Abstract
The utility model discloses a leakage testing device for a roll-bond evaporator. The leakage testing device comprises a rack, and is provided with a leakage testing air hole at the central position, wherein the lower end of the leakage testing air hole is in abutment joint with a seal joint, the other end of the leakage testing air hole is connected with an air source outlet on an air cylinder, the top end of the air cylinder is connected with a pressure gauge, and a seal ring is fixed below the seal joint. The leakage testing device is fixed on a panel, and one end of the panel is provided with a fixing column so as to be fixed with the rack. The leakage testing device disclosed by the utility model presents a leakage testing method of the roll-bond evaporator through data, the leakage testing precision is improved, the product quality is ensured, and problems of follow-up part abandonment caused by leakage are minimized. The leakage testing device disclosed by the utility model realizes dry type air leakage testing which is away from water, thereby solving the problem that leakage testing is carried out after bulging of the roll-bond evaporator without a muffler being welded.
Description
Technical field:
The utility model relates to a kind of leakage testing device, is specially adapted to use on roll-bond evaporator.
Background technology:
Cause evaporator to reveal because the pipeline spalling appears in the roll-bond evaporator product in Bulging Process, directly can cause refrigerator integral body not freeze if evaporator is revealed, cause refrigerator to scrap.Roll-bond evaporator must carry out leak test to product after the bulging operation is completed, every profession and trade all adopts carrying out leak test after bulging and after having welded muffler the roll-bond evaporator leak test again at present, this leak test is fairly simple can be used leak test rifle head-clamp to hold muffler to carry out leak test, if but the inflation sheet leaks muffler also along with scrapping, some client does not need to weld muffler in addition, and this will carry out leak test to workpiece after bulging.roll-bond evaporator after bulging is because pipeline blows afloat, higher than roll-bond evaporator aluminium sheet plane, out-of-flatness around inflatable mouth, if leak test just need to seal inflatable mouth, and can not carry out leak test, poorly sealed or misoperation meeting causes the water inlet of evaporation pipeline, for the roll-bond evaporator that only has a gas hole, water inlet can't be removed internal moisture, the leak test that adopts for this phenomenon at present is rubber blanket is installed on locking pliers and is established air intake opening, inflatable mouth is covered, in the evaporator both sides placement two sagging plastic ties of row, when occurring leaking, plastic ties can be blown afloat, thereby detecting workpiece leaks.Its shortcoming is: this detection can only detect the larger product of leakage, and is provided with the leak test precision, detects not the many shortcomings of storage such as science.
Summary of the invention:
Task of the present utility model is to propose a kind of raising leak test precision, has stopped the production line that causes because of leakage each procedure after the welding because of the product rejection that leakage causes, and has guaranteed a kind of roll-bond evaporator leakage testing device of product quality.
Task of the present utility model is completed like this, a kind of roll-bond evaporator leakage testing device, it comprises frame, it is characterized in that: the leakage testing device centre bit is equipped with a leak test pore, the lower end of leak test pore is to being connected to sealing adaptor, source of the gas outlet on its other end and cylinder is connected, and the cylinder top is connected with tensimeter, is fixed with O-ring seal below described sealing adaptor.Described leakage testing device is fixed on panel, and an end of panel has altered fixed leg and described frame is fixed.
The utlity model has following effect: with roll-bond evaporator leak test mode by Data Representation out, the leak test precision is improved, guaranteed product quality, and reduced to greatest extent because leakage causes follow-up accessory and scrapped problem, this kind leakage device has been realized the dry type gas leak test away from water, thereby has solved a leak test difficult problem of not welding muffler after the roll-bond evaporator bulging.
Description of drawings:
Fig. 1 is structural representation of the present utility model; Fig. 2 is welding muffler front evaporator chip architecture schematic diagram after bulging.
Drawing explanation: 1, frame, 2, roll-bond evaporator, 3, O-ring seal, 4, the leak test pore, 5, sealing adaptor, 6, cylinder, 7, tensimeter, 8, panel, 9, air admission hole.
Embodiment:
describe embodiment in detail in conjunction with above accompanying drawing, leakage testing device is fixing by bolt and panel 8, altering a fixed leg on panel is connected with frame 1, the centre bit of leakage testing device is equipped with a leak test pore 4, the lower end of leak test pore is to being connected to sealing adaptor 5, source of the gas outlet on its upper end and cylinder 6 is connected, cylinder is fixed on panel upper cylinder top and tensimeter 7 is connected, tensimeter is fixed on bearing, described sealing adaptor below is fixed with O-ring seal 3, (as shown in Figure 1), aim at sealing adaptors 5 with treating the air admission hole 9 on the roll-bond evaporator 2 of leak test, guarantee that O-ring seal 3 can seal up the air admission hole of roll-bond evaporator 2 fully, adjusting cylinder 6 presses down cylinder, at this moment to guarantee that O-ring seal flattens pipeline around the air admission hole of roll-bond evaporator but pipeline is provided with and is crushed to death, the energy air inlet, the air admission hole that O-ring seal 3 will blow on evaporator seals air tight fully, then by the leak test pore, gas is rushed in the roll-bond evaporator pipeline by the air admission hole 9 on roll-bond evaporator 2 through sealing adaptor 5, after tensimeter 7 shows that pressure reaches 0.4MPA, cut-out passes into the admission pressure of leak test pore 4 and carries out 5 seconds of pressurize, whether the pointer of observing in tensimeter in pressure maintaining period descends, descend as pointer and represent not reveal, complete the detection of leak test.
Claims (2)
1. roll-bond evaporator leakage testing device, it comprises frame, it is characterized in that: the leakage testing device centre bit is equipped with an air admission hole, the lower end of air admission hole is to being connected to sealing adaptor, source of the gas outlet on its other end and cylinder is connected, cylinder top and rain glass are connected, and are fixed with O-ring seal below described sealing adaptor.
2. a kind of roll-bond evaporator leakage testing device according to claim 1, it is characterized in that: described leakage testing device is fixed on panel, and an end of panel has altered fixed leg and described frame is fixed.
