Shengyang battery perfusion sulfuric acid solution
Shengyang battery in use (test) before, are subject to various kinds of different models of the standard and the manufacturer's instructions and requirements, perfusion the required density and temperature of sulfuric acid solution, and then after standing for a long time and the initial charge (except for dry charged battery). Therefore, it is reasonable to pour sulfuric acid solution, to ensure the normal use and maintenance of battery and battery test data is correct. It has important significance. At the same time, it also plays an important role in the intrinsic performance and life of the battery.
The use and maintenance of the filling solution of sulfuric acid
In sulfuric acid solution to appliances, mainly plastic barrels, sales of plastic water scoop, sulfuric acid solution into the funnel and the density measuring meter, thermometer etc..
Can carry a plastic bucket with a lid with sales in the process of using sulfuric acid solution with sulfuric acid solution, the acid tank with plastic bucket sales mentioned battery to reduce the labor intensity of perfusion, and the handling of the battery.
In sulfuric acid solution also need plastic shuiyaozi (volume between 1 ~ 2L is appropriate) and plastic funnel, the funnel mouth should be matched with the battery liquid injection port.
Infusion of sulfuric acid solution need to breathe in density meter and thermometer, to go through the measurement part of the check.
Two, adjust the density of sulfuric acid solution before perfusion
Before the battery sacredsun sulfuric acid solution perfusion. The density and the temperature of the sulfuric acid solution which is needed to be measured should be measured first, and the technical requirements of the test standard and the product specification shall be determined by the measurement and examination, and the confirmation of the sulfuric acid solution of the battery.
If the test value is higher than the density of sulfuric acid solution and check the requirements, should add less water, to be mixed uniformly after measuring the density and temperature values, and then reference the solution temperature coefficient is calculated, so repeated adjustment, until the deployment in accordance with the technical requirements of the sulfuric acid solution.
If the test confirms that the density of sulfuric acid solution is lower than the specified requirement. Sulfuric acid solution should be added to some of the density of 1.40g / cm3 adjustment of sulfuric acid solution, to be mixed after the measurement of the density and temperature values, and then calculated with reference to the temperature coefficient. This repeated adjustment until the deployment of technical requirements in accordance with the sulfuric acid solution.
Three, the operation method of pouring sulfuric acid solution
(a) preparation before perfusion
(1) the battery check for perfusion sulfuric acid solution appearance, pole, lid, pot, to see whether there is damage or cracks. And the surface of the battery dust, debris clean, and then the battery on the mouth of the liquid injection to unscrew the work, clear the mouth of the seal.
(2) to grasp the need to pour sulfuric acid solution battery test items, and in accordance with the test test number sequence, the battery will be used to paint the number.
(3) wear good labor protection products.
(two) operation method of pouring sulfuric acid solution
Will have been adjusted and achieve the sulfuric acid solution density and temperature values with plastic barrels sales, transported to the storage battery needs to sulfuric acid solution by perfusion (or the battery directly transported to the acid tank with side), the plastic funnel perfusion inserted into the injection port, and then use a hand held plastic funnel on the other hand, a hand to scoop water will be poured into the sulfuric acid solution slowly poured into the funnel and the battery, in the perfusion process, from the side of the battery began to gradually move to the other side. In the process of filling, please do not fill the electrolyte at once, to check whether the solution of the sulfuric acid solution at the prescribed height. In the whole cell battery perfusion after re for each single proper supplement, the sulfur solution perfusion until the battery cells within each height to meet the requirements so far. In the process of pouring sulfuric acid solution, attention should be paid to the gap between the funnel mouth and the injection hole, so that the gas in the battery can be discharged smoothly during the filling process.
Perfusion sulfuric acid solution should pay attention to the topic:
(1) adequate sulfuric acid solution shall be prepared in advance according to specifications and models.
(2) Shengyang battery perfusion to sulfuric acid solution, sulfuric acid solution surface cleaning.
(3) Shengyang battery perfusion sulfuric acid solution, using sodium carbonate and alkaline substances drip off the sulfuric acid solution on the ground, and then rinse with water.
(4) in the process of perfusion, manipulation should be careful and prudent to prevent the sulfuric acid solution from splashing onto the skin and clothing.
(three) the method of adjusting the height and temperature control of the surface of the battery pouring sulfuric acid solution
The liquid level of Shandong sacredsun battery sulfuric acid solution after reperfusion. Should comply with all kinds of product standards and product specifications. In general, the solution level in each single battery pole group protection plate 10 ~ 15mm is appropriate. For the transparent stationary battery, the liquid height should be ensured in the high and low range of the specified liquid level line. While the level of battery battery opaque height, must comply with the provisions, the lower level to the same density perfusion sulfuric acid solution to be added, to ensure the battery every single level in the same.
On the battery into the sulfuric acid solution, adjust the height of the liquid level, and placed 1 to 6h static, the temperature of the liquid should be measured, when the temperature of less than 30 degrees, before charging. If measured, the electrolyte temperature is higher than 35 DEG C, should be used to cool or cooling measures, when the electrolyte temperature dropped to the specified value, before the battery can be charged.
