Follow each development department active development energy conservation and environmental protection product. In the industrial shopping malls and industrial equipment vehicles, electric forklifts occupy certain shopping malls by virtue of their quick control, simple maintenance, quiet, pollution-free and other characteristics. Electric forklift truck is suitable for indoor operation. Most of the electric forklifts currently on the market use batteries, which are intended to be cheap. Some users asked to make up, forklift battery capacity decline quickly is what reason?
1. After leaving the factory, the external energy and timely device of the forklift battery will be applied, which will constitute a long time of storage, which will inevitably constitute a lack of capacity due to self-discharge. Since the battery is incorrect for long time storage, it should be charged at intervals.
2. The positive plate corrosion of the forklift battery caused the lack of capacity due to deformation.
The positive plate of a forklift battery is the primary factor affecting the working life of the battery. The capacity of the charging and discharging cycle of the forklift battery, especially the capacity decrease of the deep cycle, is closely related to the quality error of the positive plate.
2.1 active substances soften and fall on positive plate grid
On microscopic active substances in the holes and there is a big, big hole size beyond 0.5 cm, it is composed of many small holes through them, along with the discharge cycle, shorten the active matter appearance, constitute the center coral structure, repeated cycles using holes aggregation, make big hole keep adding, destroyed the anode structure, lead to fall of active matter.
The primary cause of these conditions is the high current charging and discharging of the forklift battery. To prevent the occurrence of charge and discharge should ensure that the current and prevent the phenomenon of over-charge or over-discharge.
2.2 corrosion deformation of positive plate grid
The corrosion speed of the grid depends on the composition of the grid alloy, but the higher the storage temperature, the faster the corrosion speed, the deeper the discharge, the more serious the corrosion.
3. Sulfuric acid of negative plate of electric forklift battery
In normal operation, PbSO4 particles on the negative plate are small, discharge is easy to recover into fluffy lead, but some time the battery produced an irretrievable lead sulfate, known as sulfuric acid salination.
The causes of negative salinization many, such as not charging in time after discharge, battery placed for long, cause severe self-discharge, electrolyte concentration is too high, the lack of charging for a long time, high temperature for a long time discharge, this kind of lead sulfate in practice it is difficult to recover, such active material cutting is bound to affect the forklift battery capacity.
