Measures to prevent battery electrolyte from freezing

battery electrolyte used on loaders is generally prepared from sulfuric acid and distilled water. Among them, the quality of sulfuric acid must comply with the standard of battery sulfuric acid (hg/t), and the quality of distilled water shall comply with the standard of lead acid battery water (ZBK). The preparation of electrolyte and initial charging of storage battery shall be operated in strict accordance with the process specification. After the battery is charged, the density of electric shock fluid shall be adjusted to 1 in winter 30, which should be adjusted to 1.28 in summer

according to the relationship between battery discharge degree, relative density and freezing point, in cold areas (below -30 ℃), if the battery does not discharge excessively (not more than 25% in winter) or the sulfuric acid in the electrolyte does not lose excessively, the electrolyte will not freeze

1. Cause of electrolyte freezing of livestock battery

the battery selected by general loaders is easy to have large electricity. When the livestock battery leaves the factory, its electrolyte density is relatively large, so as to prevent the electrolyte from forming in cold areas when there are too many electrolytic oxide scales. 5 The graph curve scale automatically optimizes auto scale ice. At the same time, it can also prevent the electrolyte density from being too small and affecting the capacity of the battery when a small amount of sulfuric acid in the electrolyte is lost. It can be seen that the main reasons for the icing of the battery electrolyte of the loader are:

(1) the sulfuric acid in the electrolyte is excessively lost during the use of the livestock battery. If only distilled water is supplemented, the relative density of the electrolyte will not meet the local climate requirements, resulting in the icing of the electrolyte

(2) theoretically, the density of the electrolyte used meets the local climate requirements. However, if the battery is over discharged, the electrolyte may freeze due to the decrease of density and the increase of freezing point

(3) when supplementing distilled water, distilled water fails to mix with electrolyte in time, resulting in local low temperature of electrolyte, which is easy to freeze

2. Preventive measures

proper use and timely maintenance of the battery can keep the battery in good technical condition, prolong its service life, and ensure the reliability of the work. In order to prevent electrolyte from freezing with economic recovery in cold areas, the following measures can be taken for daily maintenance

(1) the relative density of electrolyte shall be measured regularly. If it is found that it does not meet the requirements of measuring the size and climate of the sample, it shall be adjusted in time

(2) keep the battery fully charged. If one of the following phenomena occurs, supplementary charging must be carried out:

① when the relative density of electrolyte drops below 1.20

② when the discharge exceeds 25% in winter and 50% in summer,

③ the light is dimmer than usual, indicating that the power is insufficient

④ when the engine fails to start (not mechanical failure)

(3) if the liquid level of electrolyte is too low and distilled water needs to be added, distilled water can only be added before charging, and the water and electrolyte shall be mixed as soon as possible to reduce the possibility of electrolyte icing

(4) it is not allowed to use sulfuric acid and non distilled water for general industrial use, because they contain impurities, which will cause the battery to discharge automatically, reduce the capacity of the battery, corrode the electrode plate and shorten the service life of the electrode plate. In addition, if the density of electrolyte is too low, it is easy to freeze in cold areas

(5) when the temperature is lower than -30 ℃, the battery can be removed and moved indoors to prevent the electrolyte from freezing
