Problems solved by technology
As the number of battery cycles increases, the battery will lose water continuously, and the electrolyte needs to be replenished in time, otherwise the service life of the battery will be affected
Therefore, the control of the amount of acid in the battery has become a crucial factor. If there is too much acid, the acid will leak, and if the acid is too little, it will easily cause a series of problems, reduce the cycle life, and have the hidden danger of thermal runaway.

Embodiment Construction
[0013] The present invention is further described in conjunction with accompanying drawings.
[0014] Such as figure 1 As shown, the auxiliary acid pumping pipe is composed of a flat main pipe 1 and an arc-shaped outlet pipe 4, all of which are acid-resistant plastic pipes. The thickness of the inner cavity of the main pipe (that is, the internal gap) is 3mm, and there are multiple rows of circular through holes 2 in the middle and lower parts, the hole diameter is 5mm, and the hole spacing is 8mm, and the square plastic pillars 3 are evenly distributed inside the main pipe; The body is led out, and the width decreases from bottom to top. The outlet 5 is circular with a diameter of 8mm, matching the acid pumping device. When the battery is assembled, the auxiliary acid pumping tube is close to both sides of the pole group, clamping the pole group to facilitate battery assembly; at the same time, the square plastic pillar inside the acid pumping tube plays a supporting role to...

Abstract
The invention relates to an auxiliary acid suction pipe for formation of high-pole group lead-acid batteries, composed of a flat plastic main pipe body and an arc plastic guide-out pipe; the main pipe body is 2-4 mm in cavity thickness and is provided with multiple rows of circular through holes in the lower middle, and plastic pillars are distributed evenly in the main pipe body; the guide-out pipe is led out the main pipe body, has gradually decreasing width, and a guide-out port of the guide-out pipe is circular and mates with an acid suction apparatus. The auxiliary acid suction pipe is fitted tightly to two sides of a pole group and is simple and handy, acid suction effect for formation of high-pole group lead-acid batteries is ensured, electrolyte is supplied in time when a battery loses water inside, and cycle life of the battery is prolonged.
Description
technical field [0001] The invention relates to an auxiliary acid pumping tube for the formation of high-electrode group lead-acid storage batteries, which belongs to the field of lead-acid storage batteries. Background technique [0002] At present, the internal formation of lead-acid batteries is carried out in the form of quantitative rich liquid. In the final charging stage of formation, the excess free acid needs to be extracted. For high-electrode lead-acid batteries, due to the high battery, the formation of acid It is difficult to extract free acid during the process. Valve-regulated sealed lead-acid batteries are used in a state of poor liquid, and excessive free acid may easily cause acid leakage, especially for lead-acid batteries that are installed horizontally. As the number of battery cycles increases, the interior of the battery continues to lose water, and the electrolyte needs to be replenished in time, otherwise the service life of the battery will be affe...
