A kind of electric capacity is containing soaking technology
Technical field
The present invention relates to capacitor manufacturing technology field, refer in particular to a kind of capacitor core containing soaking technology.
Background technology
The core of existing capacitor comprise soak be mostly directly core bag is put into be equipped with containing in the container of immersion fluid by soaking for a long time, make impregnation Liquid Penetrant in positive paper tinsel, negative paper tinsel, paper, the immersion production efficiency of this mode is low, and soak time is long, impregnation effect is undesirable, and production cost is high; And the liquid after drying can not reuse, environment is caused to certain pollution; Also having at present a kind of mode is to adopt some note, with special syringe, injects the electrolyte into fuse, and this mode production efficiency is low, and labour intensity is large.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide effective, the fireballing electric capacity of a kind of impregnation containing soaking technology.
For achieving the above object, technical scheme provided by the present invention is: a kind of electric capacity is containing soaking technology, and described technique comprises the following steps:
1), the capacitance core for the treatment of impregnation is put into impregnation cylinder in order, capacitance core after putting into seals impregnation cylinder;
2), impregnation cylinder is vacuumized, when vacuumizing, make moisture and air in capacitance core be drawn out of;
3), open communicating valve, make the electrolyte suction impregnation cylinder in liquid storing barrel, close communicating valve;
4), apply malleation to the impregnation cylinder after vacuumizing, malleation value is 1.2MPa ~ 1.5MPa, then pressurize carries out impregnation to capacitance core, the impregnation time is 40 ~ 120 minutes;
5), to discharge impregnation cylinder pressure be normality, keep 15 ~ 20 minutes;
6), again impregnation cylinder is vacuumized;
7), open communicating valve, make the electrolyte suction impregnation cylinder in liquid storing barrel, close communicating valve;
8), apply malleation to the impregnation cylinder after vacuumizing, malleation value is 1.2MPa ~ 1.5MPa, then pressurize carries out impregnation to capacitance core, the impregnation time is 40 ~ 120 minutes;
9), to discharge impregnation cylinder pressure be normality, keep 10 ~ 15 minutes;
10), again impregnation cylinder is vacuumized;
11), open communicating valve, make the electrolyte suction impregnation cylinder in liquid storing barrel, close communicating valve;
12), apply malleation to the impregnation cylinder after vacuumizing, malleation value is 1.2MPa ~ 1.5MPa, then pressurize carries out impregnation to capacitance core, the impregnation time is 40 ~ 120 minutes;
13), to discharge impregnation cylinder pressure be normality, make under the effect of pressure differential, to flow back to liquid storing barrel containing immersion liquid;
14), capacitance core after impregnation is taken out, dry.
The invention has the advantages that: simple, convenient, can make the impregnation time greatly shorten, and capacitor core impregnation is effective, conventional impregnation needs 15-20 hour, adopt this technique only to need 5-8 hour, greatly shorten the impregnation time, improved production efficiency, and product quality is improved significantly, electrolyte is also utilized.
Embodiment
Below the invention will be further described, preferred embodiment of the present invention is: the electric capacity described in the present embodiment comprises the following steps containing soaking technology:
1), the capacitance core for the treatment of impregnation is put into impregnation cylinder in order, capacitance core after putting into seals impregnation cylinder;
2), impregnation cylinder is vacuumized, when vacuumizing, make moisture and air in capacitance core be drawn out of;
3), open communicating valve, make the electrolyte suction impregnation cylinder in liquid storing barrel, close communicating valve;
4), apply malleation to the impregnation cylinder after vacuumizing, malleation value is 1.5MPa, then pressurize carries out impregnation to capacitance core, the impregnation time is 40 ~ 120 minutes;
5), to discharge impregnation cylinder pressure be normality, keep 15 ~ 20 minutes;
6), again impregnation cylinder is vacuumized;
7), open communicating valve, make the electrolyte suction impregnation cylinder in liquid storing barrel, close communicating valve;
8), apply malleation to the impregnation cylinder after vacuumizing, malleation value is 1.3MPa, then pressurize carries out impregnation to capacitance core, the impregnation time is 40 ~ 120 minutes;
9), to discharge impregnation cylinder pressure be normality, keep 10 ~ 15 minutes;
10), again impregnation cylinder is vacuumized;
11), open communicating valve, make the electrolyte suction impregnation cylinder in liquid storing barrel, close communicating valve;
12), apply malleation to the impregnation cylinder after vacuumizing, malleation value is 1.2MPa, then pressurize carries out impregnation to capacitance core, the impregnation time is 40 ~ 120 minutes;
13), to discharge impregnation cylinder pressure be normality, make under the effect of pressure differential, to flow back to liquid storing barrel containing immersion liquid;
14), capacitance core after impregnation is taken out, dry.
The embodiment of the above is only the present invention's preferred embodiment, not with this, limits practical range of the present invention, therefore the variation that all shapes according to the present invention, principle are done all should be encompassed in protection scope of the present invention.
