叉车启动用蓄电池的工作原理

叉车蓄电池分为电动叉车及内燃叉车两种,我们现在说的是内燃叉车启动用蓄电池,这种与汽车电瓶--样,只是辅助发电机启动马达,但也是一个

不可忽视的叉车配件,其工作原理:叉车电池的充放电过程就是电池内部电能和化学能相互转化的过程。充电时,正、负极由硫酸铅转化二氧化

铅、海绵状铅后将电能转化为化学能储存在正极、负板中;在放电时,正、负极由二氧化铅、海绵状铅转化为硫酸铅而将化学能转化成电能向负载

供电,上述的化学反应过程由公式来表示。可分为加水及免维护型蓄电池,目前国内处于环保高热期,基本以免维护叉车电池形式出现了，称

为免维护电池,但只是指在使用过程中不需加酸、加水、测比重等工作,免维护不等于不维护,而维护的好坏则直接决定电池的使用寿命。下面就

其可能出现的故障进行分析:

漏酸:在使用初期(2年以内)有明显的电解液流出或溢出。主要有壳体漏和安全阀漏。造成原因:有可能是电池的外壳漏了(有沙眼或有裂纹)或

安全阀漏了(电池内多酸,在充电时内部产生气体，使电解液上浮,导致酸从安全阀溢出)。这种情况-般与电池制造商的工艺设计及质量有关。

危害:这不仅会影响电池的容量,流出或溢出的酸对电池及电池柜造成腐蚀,并对周围的环境造成污染。

The working principle of aforklift starting battery

Forklift batteries are dividedinto two types: electric forklifts and internal combustionforklifts. What we are talking about now is the starting batteryfor internal combustion forklifts. This type of battery, similar toautomotive batteries, is only an auxiliary generator startingmotor, but it is also a

The working principle offorklift accessories that cannot be ignored is that the chargingand discharging process of forklift batteries is the process ofconverting internal electrical and chemical energy into each other.During charging, the positive and negative electrodes are convertedfrom lead sulfate to dioxide

Lead, sponge like lead,converts electrical energy into chemical energy and stores it inthe positive and negative plates; During discharge, the positiveand negative electrodes are converted from lead dioxide and spongelike lead to lead sulfate, converting chemical energy intoelectrical energy and transferring it to the load

Power supply, the abovechemical reaction process is represented by a formula. It can bedivided into water added and maintenance free batteries. Currently,China is in a period of high environmental protection, whichbasically avoids the appearance of maintenance forkliftbatteries

To avoid maintenance of thebattery, it simply means that there is no need to add acid, water,or measure the specific gravity during use. Maintenance free doesnot mean no maintenance, and the quality of maintenance directlydetermines the service life of the battery. Below is the

Analyze the possiblefaults:

Acid leakage: There is obviouselectrolyte leakage or overflow in the early stage of use (within 2years). There are mainly shell leakage and safety valve leakage.Cause: It is possible that the battery casing is leaking (with sandholes or cracks) or

The safety valve is leaking(there is too much acid in the battery, which generates gasinternally during charging, causing the electrolyte to float andcausing the acid to overflow from the safety valve). This situationis generally related to the process design and quality of batterymanufacturers.

Hazard: This not only affectsthe capacity of the battery, but also the acid flowing out oroverflowing causes corrosion to the battery and battery cabinet,and pollutes the surrounding environment.
