The main driving force of the electric forklift is derived from the battery pack. Since the forklift battery is a water battery, it is necessary to make hydrating, density, etc. , The heterogeneous electrolyte liquid level height of the forklift battery should be higher than the polar plate 10-15mm. Keeping the altimeter of each monobiic electrolyte liquid in the battery is the most basic requirement for extending battery life. The method of examination of the electrolyte liquid level is: Unscrew the hemata cover, inserted into the plug in the glass tube with a glass tube of about 7mm inner diameter. The index finger and unnamed the glass tube, gently propose, the height of the electrolyte in the glass tube is the height of the electrolyte plane of the battery, should be 10-15mm. After the examination, finally put the electrolyte in the original single battery. If the battery electrolyte liquid is too low, it should be supplemented with the battery supplementation liquid sold in the distilled water or the market. It is not allowed to add water such as tap water, river water, well water, etc., so as to avoid mixing impurities, causing self-discharge failure. Do not add a standard electrolyte, otherwise, the concentration of the electrolyte will increase, shorten the battery life of the battery. Since the density of the forklift battery electrolyte, the lower the solidification point, the driver in winter can choose the appropriate electrolyte density according to the local minimum temperature. When the lowest temperature is 0 ¡ã C, an electrolyte having a density of 1.26 g / cm3 is selected; if the ambient temperature in the northern region is 10 ¡ã C, the selected electrolyte shall be increased by 0.01 g / cm3. After the car is strictly prohibited, the distilled water is added, and the distilled water added in the upper portion of the lower portion cannot be mixed with sulfuric acid.
In the forklift battery, the internal burner occupies a small portion of the start battery, periodically measured the density of the battery electrolyte, normal should be 1.23g / cm3 (except for maintenance battery). The method of measuring the electrolyte density is: unscrew each of the plug-in ports of the battery, and use a densitometer to absorb the electrolyte to the densitometer float. When the density is subjected to a position of the eye, the reading is observed, ensuring the accuracy of the reading. The high low of the electrolyte density of the battery is varied as the extent of the battery, the degree of decrease in the electrolyte density is a manifestation of the degree of discharge of the battery. Measure the electrolyte density in each single-single, you can understand the degree of discharge of the battery. When the electrolytic solution density is less than 1.23 g / cm3 (15 ¡ã C), the battery should be charged. The electrolyte density is specified to be measured at 15 ¡ã C, if the temperature is below 15 ¡ã C or higher than 15 ¡ã C, the actual temperature of the electrolyte should be measured using the thermometer to calculate the correction value of the electrolyte density. In addition, according to the temperature regulation of the electrolyte density, the battery electrolyte density should be determined according to the region and season conditions. Density is too high, affecting battery life; too low, easy to cause electrolyte winter icing. The difference between the different battery of the same battery should not be greater than 0.01. If a single-single battery electrolyte density is too large, the internal battery may have faults, and the reason should be identified, and it is repaired.
Forklift battery charging process
1. Check before charging: Whether the battery is intact, whether the wiring is intact, and open the air cover.
Do not open or dial out the liquid plug on the battery;
Do not add liquid before charging or charging;
Smoking is strictly prohibited in the batteries, spark or open fire;
The battery cannot be discharged at the time of charging;
Do not put the metal tool on the battery when charging;
Do not repair the battery when charging;
The electrolytic solution temperature is lower than 55 ¡ã C during charging.
2, if the new battery is cooled to the electrolyte of 1.26 to 30 ¡ã C, the battery is injected into the battery, and the injection amount is higher than the protective plate 10 to 20 mm, waiting for 6 hours, the liquid temperature dropped below 35 ¡ã C. Start charging. The electrolyte specific gravity is 10 ¡ã C, and the different temperature should be converted according to the following formula: D30 ¡ã C = DT + 0.007 (T-30 ¡ã C)
4, when the battery is charged to saturation, the voltage and electrolyte is basically not rising within 2 to 3 hours, and a large amount of air bubbles, the electrolyte is more than 1.26, and the single voltage is 2.4V.
5. When the single voltage dropped to 1.7V, the voltage meter voltage 41V (driving load), the electrolysis specific gravity decreases to 1.18, should be charged in time.
6. When charging battery charging, the electrolyte specific gravity is 1.26 with distilled water or a specific gravity of 1.4, and the electrolyte specific gravity is 1.26 and maintains a sufficient height. Battery charging start ends should be recorded for voltage electrolyte. Record will help the maintenance and protection analysis of the battery.
7. Do not near the fire and heat sources. After the charging is completed, the gas cover is covered, and the electrolyte is wiped out, keep the joint clean and dry, and apply Vaseline. Battery flushing must be carried out outside the car.
8. The battery charging environment must be well ventilated. Especially with the car is charged around the air. The battery charger has a good ventilation device, and the temperature is not higher than 40 ¡ã C, and the air flow can be calculated to avoid the accumulation of hydrogen-oxygen mixed gas during battery charging. The following formula can be calculated: q = 0.05 ¡Á I ¡Á n (where Q : Air flow, I: Charging the final charging current, N: Battery monomer), should ensure that the air flow between the charging is greater than the amount of air flow in the calculation formula.
9, the beginning of the battery, often charged data can be refer to the table below, (such as the battery belt manual, please follow the instructions)
Forklift battery safety instructions
First, daily inspection
1, liquid plane
Lower than rated liquid, will shorten the battery life of the battery, and the electrolyte is too small to cause heat storage, so it must be noted that the electrolyte is sufficient.
2, terminal column, wire, cover
The battery terminal joint must be often checked, and the connection caused by oxidation due to oxidation, while checking whether the lid is deformed due to oxidation.
The battery surface is dirty will cause leakage, which should make the battery surface clean and dry.
1, add water
Add distilled water at a specified liquid surface, do not add excessive distilled water to extend the water space interval, and the water is overproduced, resulting in leakage.
During the charging process, the battery will generate a gas, and should keep the charging site well, there is no open flame around the charging, and the oxygen generated during the charging process will affect the surroundings.
Exploring the charging plug during charging will generate an arc, and the plug can be unplugged after the charger is closed.
After charging, many hydrogen are left around the battery, and there is no open flame, which should open the cover on the battery for charging.
3, wiring column, wire, cover repair
The professional technicians specified by the manufacturer can be performed.
If it is not too dirty, it can be wiped with wet cloth. If it is very dirty, it is necessary to remove the battery from the car and clean it naturally.
