Piping is connected between pressurization mouth and the liquid outlet of liquid storing barrel of impregnation cylinder such that it is able to apply electrolyte
Pressurization.It is understood that may also take on other modes to apply malleation, such as by fluid pressurization
Mode realizes.
In the present embodiment, after making impregnation cylinder be released to normal pressure by vacuum state and be applied malleation, electrolyte is subject to
Pressure between 4 kilograms～5 kilograms, such as 4.3 kilograms, improve impregnation pressure, and then can carry
The efficiency of high impregnation.Wherein, kilogram it is the China's a kind of describing mode to gas pressure unit.
Step S250, control core bag to be impregnated with and be kept in motion in the electrolytic solution.
Wherein it is possible to make core bag to be impregnated be in motion in the electrolytic solution by the way of vibration wave or rotation
State, so that electrolyte enters in core bag to be impregnated with within a short period of time, to improve impregnation effect.Example
As, core bag to be impregnated with can be controlled by ultrasonic unit and be kept in motion.
It is understood that the executive mode of impregnation operation is not limited to above-mentioned a kind of situation, as long as can improve
The speed of impregnation, such as step S250 can also perform between step S230 and step S240.
Further, in nail volume operation, before being wound, as it is shown on figure 3, first add on negative paper tinsel 110
Liner 120, and liner 120 is identical with the material of negative paper tinsel 110.Such as liner 120 and the material of negative paper tinsel 110
Paper tinsel is born in the pressurization being F3-3.0VF.Liner 120 can be avoided inside this aluminium electrolutic capacitor because electric current is excessive
