Abstract

The invention provides a starting valve control type lead acid storage battery with pure water chambers, which mainly comprises a battery jar and a battery cover, wherein the battery jar is divided into twelve unit cells by middle walls; the battery cover is matched with the battery jar; the unit cells are arranged in two lines; one line of the unit cells are plate group chambers, plate groups are placed in the plate group chambers, and electrolyte is poured into the plate group chambers; the other line of the unit cells are the pure water chambers, and pure water or the electrolyte is poured into the pure water chamber; and each plate group corresponds to one pure water chamber, and a communicating guide tube and a communicating pore are arranged between the plate group and the corresponding pure water chamber. The plate groups are compactly assembled with a plurality of pieces, a positive plate grid is made of lead antimony alloy, a negative plate grid is made of lead calcium alloy, the mesh density of the positive plate grid and the negative plate grid is high, and the lead acid storage battery is provided with the pure water chambers, the communicating guide tubes and the communicating pores to ensure that an absorbent glass mat (AGM) separator is automatically adjusted into an under-saturated optimum state, and even working under a 50 DEG C high temperature environment, the storage battery not only has a long cycle service life but also has minimal water loss, is not lack of water during years of service life, and achieves to be real maintenance-free.

Description

technical field

[0001] The invention relates to a lead-acid storage battery for starting, which is mainly used in the fields of automobiles, tractors, construction machinery, etc., and specifically refers to a valve-controlled lead-acid storage battery for starting with a pure water chamber. Background technique

[0002] The structure of lead-acid storage battery mainly contains positive (negative) pole plate, dividing plate, electrolyte, battery tank, connecting bar and positive and negative terminal etc. to form, and positive (negative) pole plate is that grid among the present invention is coated with lead paste constitute. A lead-acid battery is a device that converts chemical energy into electrical energy and belongs to the DC power supply.

[0003] At present, the manufacturing process of valve-regulated lead-acid batteries (abbreviated as VRLA) with ABS plastic battery tank covers is roughly as follows:

[0004] Alloy Configuration→Grid Manufacturing→Mechanical Coat...

Examples

Embodiment

[0038] Such as Figure 1-8 As shown, the valve-regulated lead-acid battery with the pure water chamber 5 is mainly composed of a battery tank 1 divided into twelve cells by an intermediate wall 3, and a battery cover 2 matching the battery tank 1. The battery tank 1, the middle wall 3 and the battery cover 2 are all made of PP plastic material.

[0039] Such as Figure 4 As shown, the single-cell battery tank 1 is distributed in two rows, one of which is the electrode group chamber 12, and the electrode group 4 is placed in the electrode group chamber 12 and filled with electrolyte, and the other row is the pure water chamber 5 Each pole group 4 corresponds to a pure water chamber 5, and a communication conduit 6 is provided between the pole group 4 and the corresponding pure water chamber 5, and the communication conduit 6 extends to the bottom of the pure water chamber 5. Such as Figure 8 As shown, in the lower section of the intermediate wall 3 between the pole group ch...
