Analysing valve control type lead-acid accumulator battery and assembly technology
Technical field
The present invention relates to a kind of lead-acid accumulator, more specifically, it relates to which a kind of bus-bar is uncorruptible valve-regulated
Lead-acid accumulator and assembly technology.
Background technology
Lead-acid accumulator in use for some time, engenders white acidic materials on its positive and negative terminals, connecting line,
Severe patient pole position occurs being commonly referred to as climbing acid or seepage in leakage, pole root scaling loss or corrode phenomenon, industry(It is referred to as in text
To climb acid).By dissecting climbing acid accumulator, it is found that the pole set surface of terminal is corroded in various degree, sulfuric acid is along corrosion
Under the passage effect such as air pressure or liquid fluctuating internally, leaked out from internal storage battery, in terminal surfaces or battery cap
One layer of sulfuric acid liquid film is formed, that is, climbs sour phenomenon.
The bus-bar of lead-acid accumulator is permanently connected to electrolyte, and oxygen is produced in charging process, and bus-bar is gradually rotten
Erosion, if component of bus-bar alloy itself is uneven, can cause bus-bar alloy crystal boundary and the difference of the chemical composition in crystal grain,
Corrosion galvanic cell is formd in sulfuric acid electrolyte, crystal boundary corrodes first, the intercrystalline corrosion of large area causes bus-bar to close
Adhesion is lost between Jin Jing's grain, metal strength declines, the destruction of bus-bar premature corrosion ultimately results in battery failure.
Chinese patent notification number CN202550016U, is disclosed outside a kind of lead-acid batteries, including battery case, battery
Include multiple monomer lead acid storage batteries independent of each other in shell, each monomer lead acid storage battery includes a cell group, each list
Body lead-acid accumulator is one another in series, positioned at the idle positive pole of two monomer lead acid storage batteries at head and the tail edge and idle negative pole point
Not Cheng Wei lead-acid batteries positive terminal and negative terminal.Easily there is pole in the lead-acid accumulator of this structure
Post climbs sour phenomenon, and bus-bar corrosion phenomenon, so as to reduce the service life of battery.
The content of the invention
Easily there is pole instant invention overcomes existing lead-acid accumulator and climb sour phenomenon and bus-bar corrosion phenomenon, from
And reduce service life not enough of battery there is provided a kind of analysing valve control type lead-acid accumulator battery and assembly technology, battery assembling
After the completion of be less prone to pole and climb sour phenomenon and bus-bar corrosion phenomenon, it is ensured that the service life of battery.
In order to solve the above-mentioned technical problem, the present invention uses following technical scheme:A kind of analysing valve control type lead-acid accumulator battery, including
