The device comprises a sealer and an upper cover matched with the sealer, a sealing ring is arranged on the upper end face, making contact with the upper cover, of the sealer, the upper cover is connected with a pneumatic pump through an air duct, and a pneumatic switch, a pressure valve, a pressure adjusting valve and a pressure display gauge are sequentially arranged between the sealer and the pneumatic pump. The device has the advantages of being simple in structure, convenient to use, easy to operate, high in working efficiency and capable of improving stability of detection of product performance and the usage rate of products.
Description
Technical field
The present invention relates to a kind of device for detecting sealability, particularly a kind of electrolytic capacitor sealing device for detecting sealability and detection method thereof.
Background technology
At present, in screw bolt-type electrolytic capacitor sealing manufacture process, between aluminum hull and cover plate, the plate face of cover plate and explosion-proof plug and cover plate between easily produce gas leak phenomenon, and sealing is main by capacitor directly being put on the hot water surface level of constant temperature, then observe and whether have Bubble formation, this detection method can only detect the poor cover plate of sealing and the serious bad product of sealing leak, and owing to being to detect in hot water, being difficult to tell is the bubble that hot water itself produces on earth, or due to the bubble of product sealing blow-by generation, be easy to produce misjudgment phenomenon, and it is the poor sealing between bolt and cover plate that concrete inspection does not measure, or the poor sealing of explosion-proof plug, or the problem of sealing between sealing deficiency and explosion-proof plug and the cover plate of the plate face of cover plate, be difficult to detect concrete Gas leak position, therefore also cannot be further improved for the problem producing.In addition, the impermeability of testing product poach heat, in the time that temperature reaches 100 DEG C, in product placing container, after 5 minutes, to observe and to have or not Bubble formation.Poach heat in this process, needs consuming time longlyer, and is difficult for keeping constant temperature, when product is put into hot water, must just can test after being heated product aluminum hull inside such as grade, and efficiency and the energy are all had to waste.When cause is done airtight test, must put into hot water by whole product, if there is the bad product of impermeability, easily have water to suck product inherence, the critical defect that the immersion of moisture is capacitor, product can not reuse, and has caused the waste of product
Summary of the invention
The present invention, in order to overcome the deficiencies in the prior art, provides a kind of: electrolytic capacitor sealing device for detecting sealability and detection method thereof simple in structure, easy to use, simple to operate, work efficiency is high.
Object of the present invention is achieved through the following technical solutions: a kind of electrolytic capacitor sealing device for detecting sealability, comprise sealer and the upper cover matching with it, the upper surface contacting with upper cover at sealer is provided with O-ring seal, be connected with air lift pump upper covering by wireway, between sealer and air lift pump, be provided with successively pneumatic switch, air pressure valve, pressure-regulating valve and pressure display table.
A kind of electrolytic capacitor sealing device for detecting sealability detection method, electrolytic condenser to be measured is put into sealer, add ethylene glycol in electrolytic capacitor sealing surrounding and cover plate plane, cover upper cover, guarantee sealer sealing, after capping, close pneumatic switch, open again air pressure valve, observe tensimeter, as reach-0.075 ± 0.005Mpa of negative pressure, close air pressure valve, then estimate, in one minute, observe ethylene glycol face and whether have Bubble formation, observe bolt and cover plate junction and whether have Bubble formation, whether the explosion-proof plug of observing on cover plate has Bubble formation, whether the junction of observation and explosion-proof plug and cover plate has Bubble formation, whether the plate face of observing cover plate has Bubble formation, if any Bubble formation, for substandard product, if there is no Bubble formation, be certified products.Open pneumatic switch the air release in sealer is gone out, then the water on electrolytic condenser cover plate top is sopped up and dry with rag.
The present invention compared with prior art has advantages of: simple in structure, easy to use, simple to operate, work efficiency is high, the stability of enhancing product performance and detecting, improves product utilization rate.
brief description of the drawings:
Fig. 1 is structural representation of the present invention;
Number in the figure: 1-sealer, 2-upper cover, 3-O-ring seal, 4-wireway, 5-air lift pump, 6-pneumatic switch, 7-air pressure valve, 8-pressure-regulating valve, 9-pressure display table.
embodiment:
In order to deepen the understanding of the present invention, below in conjunction with embodiment and accompanying drawing, the invention will be further described, and this embodiment only, for explaining the present invention, does not form limiting the scope of the present invention.
As Fig. 1 shows the embodiment of a kind of electrolytic capacitor sealing device for detecting sealability of the present invention: the upper cover 2 that comprises sealer 1 and match with it, the upper surface contacting with upper cover 2 at sealer 1 is provided with O-ring seal 3, on upper cover 2, be connected with air lift pump 5 by wireway 4, between sealer 1 and air lift pump 5, be provided with successively pneumatic switch 6, air pressure valve 7, pressure-regulating valve 8 and pressure display table 9.
A kind of electrolytic capacitor sealing device for detecting sealability detection method, electrolytic condenser to be measured is put into sealer 1, add ethylene glycol in electrolytic capacitor sealing surrounding and cover plate plane, cover upper cover 2, guarantee that sealer 1 seals, after capping, close pneumatic switch 6, open again air pressure valve 7, observe tensimeter, as reach-0.075 ± 0.005Mpa of negative pressure, close air pressure valve 7, then estimate, in one minute, observe ethylene glycol face and whether have Bubble formation, observe bolt and cover plate junction and whether have Bubble formation, whether the explosion-proof plug of observing on cover plate has Bubble formation, whether the junction of observation and explosion-proof plug and cover plate has Bubble formation, whether the plate face of observing cover plate has Bubble formation, if any Bubble formation, for substandard product, if there is no Bubble formation, be certified products.Open pneumatic switch 6 air release in sealer 1 is gone out, then the water on electrolytic condenser cover plate top is sopped up and dry with rag.
The present invention is simple in structure, easy to use, simple to operate, work efficiency is high, and the stability of enhancing product performance and detecting improves product utilization rate, in sealing surrounding, and cover plate plane adds ethylene glycol, if there is sealing bad, there is ethylene glycol to suck, do not affect product endoplasm.
