叉车电动电力短缺应该注意什么?

来源:/ 日期:2021-07-30 发布人:hangong

1.电动叉车电池不在安装时间,导致长期储存。

1. The battery of electric forklift is not installed for a long time, resulting in long-term storage.
长期存放会导致电池自放电,导致容量不足。如果电池存放时间较长,应定期充电。
Long term storage will lead to battery self discharge and insufficient capacity. If the battery is stored for a long time, it should be charged regularly.
2.电池正极板腐蚀变形导致容量不足
2. The battery positive plate is corroded and deformed, resulting in insufficient capacity
影响电池寿命的主要因素是叉车电池的正极板。电动叉车,电池充放电循环容量,特别是深循环容量的下降与正极板质量密切相关。
The main factor affecting battery life is the positive plate of forklift battery. For electric forklift, the decrease of battery charge discharge cycle capacity, especially deep cycle capacity, is closely related to the quality of positive plate.
微活性物质中有大孔和微孔,大孔尺寸大于0.5厘米,许多微孔呈组成状,随着放电循环,活性物质表面收缩,形成核心,呈现珊瑚的结构。多次放电会导致小孔堆积,大孔增多,破坏正结构,导致活性物质脱落。
There are macropores and micropores in the micro active material. The size of macropores is greater than 0.5cm, and many micropores are composed. With the discharge cycle, the surface of the active material shrinks to form a core and presents the structure of coral. Multiple discharges will lead to the accumulation of small holes, the increase of large holes, the destruction of positive structure and the falling off of active substances.
这些情况主要是由叉车电池的大电流充放电造成的。因此,在使用电池时,应确保充放电电流,以避免过充电或过放电。

These conditions are mainly caused by high current charging and discharging of forklift battery. Therefore, when using the battery, ensure the charge and discharge current to avoid overcharge or over discharge.
格栅的腐蚀速率取决于格栅合金的成分。储存温度越高,腐蚀速度越快,放电深度越深,腐蚀越严重。
The corrosion rate of the grid depends on the composition of the grid alloy. The higher the storage temperature, the faster the corrosion rate, the deeper the discharge depth, and the more serious the corrosion.
3.电动叉车,电池负极板的硫化
3. Vulcanization of battery negative plate of electric forklift
正常运行时,负极板上PbSO4 _ 4粒径小,放电容易回收成蓬松的铅,会变成硫酸盐。不能及时充电,电池长期使用会导致自放电严重,电解液浓度过高,长期充电不足,高温长期放电会导致负极盐化。这种硫酸铅很难用常规方法还原,因此活性物质的还原必然会影响叉车电池的容量。
During normal operation, PbSO4 on the negative plate_ 4. The particle size is small, and the discharge is easy to recover into fluffy lead, which will turn into sulfate. If the battery cannot be charged in time, the long-term use of the battery will lead to serious self discharge, high electrolyte concentration, insufficient charging for a long time, and long-term discharge at high temperature will lead to negative salinization. This lead sulfate is difficult to be reduced by conventional methods, so the reduction of active substances will inevitably affect the capacity of forklift battery.
只需轻轻击碎电池的小盖,看看电池盖是否干燥,或者水量是否达到警戒线,就可以判断电池是否需要水。此外,电池板用白色玻璃纤维棉包裹,正常情况下应该是湿的。
Just gently break the small cover of the battery and see whether the battery cover is dry or whether the water volume reaches the warning line, you can judge whether the battery needs water. In addition, the battery board is wrapped with white glass fiber cotton, which should be wet under normal circumstances.
