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
Its detection method.
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
Gas leak phenomenon is easily produced between explosion-proof plug and cover plate, and the main hot water by capacitor being directly placed into constant temperature of sealing
On horizontal plane, then having seen whether that bubble produces, this detection method can only detect the poor cover plate of sealing and serious
The bad product of sealing leak, and owing to being to detect in the hot water, being difficult to tell is that hot water itself produces on earth
Bubble, or the bubble produced due to product sealing blow-by, it is easy to produce misjudgment phenomenon, and concrete inspection not measure be bolt
And the poor sealing between cover plate, or the poor sealing of explosion-proof plug, or the sealing in the plate face of cover plate is not enough to
And the problem of the sealing between explosion-proof plug and cover plate, it is difficult to detect concrete Gas leak position, the most also cannot be for generation
Problem is further improved.It addition, the air-tightness of product to be detected must be decocting in water heat, when temperature reaches 100 DEG C,
In product placing container, observe after 5 minutes and have bubble-free to produce.Decocting in water heat in this process, needs the longest, and is difficult to protect
Hold constant temperature, when product is put in hot water, it is necessary to wait and just can test after being heated inside product aluminum hull, equal to efficiency and the energy
There is waste.Because must putting in hot water by whole product when doing airtight test, if there being the bad product of air-tightness, water is easily had to inhale
Entering in product and to immerse the critical defect for capacitor at, moisture, product can not reuse, and causes the waste of product
Summary of the invention
The present invention is in order to overcome the deficiencies in the prior art, it is provided that a kind of: simple in construction, easy to use, simple to operate, work
Electrolytic capacitor sealing device for detecting sealability that efficiency is high and detection method thereof.
The purpose of the present invention is achieved through the following technical solutions: a kind of electrolytic capacitor sealing device for detecting sealability,
Including sealer and matched upper cover, the upper surface contacted with upper cover at sealer is provided with sealing ring, covers upper
Connected by airway and have pulsometer, between sealer and pulsometer, be sequentially provided with pneumatic switch, air pressure valve, pressure-regulating valve
And pressure display table.
A kind of electrolytic capacitor sealing device for detecting sealability detection method, puts into sealer by electrolysis condenser to be measured
In, add ethylene glycol in electrolytic capacitor sealing surrounding and cover plate plane, cover upper cover, it is ensured that sealer seals, close after capping
Close pneumatic switch, then open air pressure valve, observe Pressure gauge, when negative pressure reaches-0.075 ± 0.005Mpa, close air pressure valve, then
Estimate, in one minute, observe whether ethylene glycol face has bubble to produce, observe whether bolt has bubble to produce with cover plate junction
Raw, whether the explosion-proof plug observed on cover plate has bubble to produce, and whether observation and explosion-proof plug has bubble to produce with the junction of cover plate, sees
Whether the plate face examining cover plate has bubble to produce, and produces if any bubble, for substandard product；Produce without bubble, for qualified
Product.Open pneumatic switch to be discharged by the gas in sealer, then the water on electrolysis condenser cover plate top is sopped up and uses and smear
Cloth is dried.
The present invention compared with prior art has the advantage that: simple in construction, easy to use, simple to operate, work efficiency is high,
Enhance product performance detection stability, improve product utilization rate.
Accompanying drawing illustrates:
Fig. 1 is the structural representation of the present invention；
Label in figure: 1-sealer, 2-upper cover, 3-sealing ring, 4-airway, 5-pulsometer, 6-pneumatic switch, 7-air pressure
Valve, 8-pressure-regulating valve, 9-pressure display table.
Detailed description of the invention:
In order to deepen the understanding of the present invention, below in conjunction with embodiment and accompanying drawing, the invention will be further described, should
Embodiment is only used for explaining the present invention, is not intended that limiting the scope of the present invention.
As Fig. 1 shows the detailed description of the invention of the present invention a kind of electrolytic capacitor sealing device for detecting sealability: include
Sealer 1 and matched upper cover 2, the upper surface contacted with upper cover 2 at sealer 1 is provided with sealing ring 3, at upper cover 2
On by airway 4 connect have pulsometer 5, be sequentially provided with between sealer 1 and pulsometer 5 pneumatic switch 6, air pressure valve 7, pressure
Force regulating valve 8 and pressure display table 9.
A kind of electrolytic capacitor sealing device for detecting sealability detection method, puts into sealer 1 by electrolysis condenser to be measured
In, add ethylene glycol in electrolytic capacitor sealing surrounding and cover plate plane, cover upper cover 2, it is ensured that sealer 1 seals, after capping
Close pneumatic switch 6, then open air pressure valve 7, observe Pressure gauge, when negative pressure reaches-0.075 ± 0.005Mpa, close air pressure valve
7, then estimate, in one minute, observe whether ethylene glycol face has bubble to produce, observe whether bolt has with cover plate junction
Bubble produces, and whether the explosion-proof plug observed on cover plate has bubble to produce, and whether observation and explosion-proof plug has bubble with the junction of cover plate
Producing, whether the plate face observing cover plate has bubble to produce, and produces if any bubble, for substandard product；Produce without bubble,
For certified products.Open pneumatic switch 6 to be discharged by the gas in sealer 1, then the water on electrolysis condenser cover plate top is inhaled
Fall and dry with rag.
Present configuration is simple, easy to use, simple to operate, work efficiency is high, the stability of detection of enhancing product performance,
Improving product utilization rate, in sealing surrounding, and cover plate plane adds ethylene glycol, if there being sealing bad, has ethylene glycol to suck,
Do not affect product endoplasm.
