We all know that water addition maintenance is a maintenance process written in the operation manual of electric forklifts, and water addition training will not be missed during employee training. During the use of the battery, it will appear: the battery is short of water, the battery will become hot, and during the charging process can get very hot. Some batteries even swell. In this case, the battery is severely dehydrated and is basically on the verge of being scrapped.
Let’s take a look at what factors affect the water loss of lead-acid batteries
1.Moisture volatilizes naturally, which is affected by the temperature of the working environment and the working intensity of the forklift. The battery will become hot during high-intensity work, which leads to constant changes in the ambient temperature;
2.During the charging reaction, water is electrolyzed into hydrogen and oxygen is lost. If the battery is overcharged, this reaction will be exacerbated;
3.If the match between the charger and the battery is poor, we don’t even know if the battery is overcharged;
4.If the characteristics of the battery are not balanced, there will be partial overcharge, that is, some battery cells will consume water faster
5.These are not bad. Most of the time, lead-acid electric forklifts are equipped with spare batteries. When the workload increases, several batteries go back and forth. You don’t know if the piece under your butt has been filled with water recently. It’s the same as the one you just finished adding water Did the battery go to someone else?
How about it, don’t you get dizzy just thinking about it? Someone said: Then let the forklift master check whether the battery is short of water every day?
In fact, in the face of a huge forklift battery pack, it is not only troublesome to add water, but also a lot of effort to check it once.
So how to judge whether the lead-acid battery is short of water?
Of course, we still have methods in the face of this situation, just as the Hubei Lham battery liquid level indicator, what in my hand is a professional forklift water shortage alarm, as long as it is installed on the forklift when the time comes Whether the forklift is short of water, you can tell at a glance, and there is also a buzzer reminder, so that the forklift can call itself when it is thirsty!
This product has the warning function of the water shortage state of the rich liquid lead-acid battery, which can help the user to know the water shortage information of the battery in time, and remind the user to add water to the battery in time for maintenance (only distilled water or deionized water can be added), so as to ensure the normal use of the battery and prolong the battery life. life.
Working principle of battery liquid level indicator
The device is directly connected to the positive and negative poles of the battery as the operating power of the device. When the electrolyte is below the sensing rod, the device judges that the battery is in a state of water through the electrical signal, the indicator light is off, and the buzzer does not sound. When the electrolyte is lower than the sensing rod , the device determines that the battery is in a state of water shortage, the warning light (red light flashes), and the buzzer warns (normal mode).
Normal mode: Water shortage warning light and buzzer warning work together
Silent mode: only the water shortage warning light works, use the buzzer switch to switch modes
The battery liquid level indicator is mainly used for the water filling reminder of the electric forklift. At present, the main driving force of the electric forklift in the world comes from the lead-acid battery. This kind of open-mouth rechargeable battery must be maintained and hydrated in order to continue to produce organic Chemical electromagnetic energy, adding water is an indispensable stage.
As forklift accessories, the purchase cost of forklift batteries accounts for a relatively high proportion. Good maintenance habits are conducive to the continuation of the service life of forklift batteries. Remind the forklift driver to add water. In the case of lack of pure water, the liquid level indicator can flash the light effect to prompt, which greatly solves the “blind spot” of the time for moisturizing.
