叉车铅酸蓄电池DA-500

叉车铅酸蓄电池DA-500，是80V500Ah的叉车电瓶，铭牌型号多数标记：40-5DB500、40-5PZB500、40-D-500、DA-500、40-5PBS500；可适用合力叉车、杭州叉车、宝骊叉车、江淮叉车、台励福叉车、美科斯叉车、柳工叉车、诺力叉车、大连叉车、无锡开普叉车等3吨～3.5吨的电瓶叉车，具备深循环1000次以上的能力，大电流输出平稳。 叉车蓄电池的充电，由于条件的限制，一般都采用常规充电法。常规充电一般有以下3种：（一）恒流充电法。在充电过程中充电电流始终保持不变，叫做恒定电流充电法，恒流充电法是用调整充电装置输出电压或改变与蓄电池串联电阻的方法，保持充电电流强度不变的充电方法；（二）阶段充电法。此方法包括二阶段充电法和三阶段充电法：1.二阶段法。采用恒电流和恒电压相结合的快速充电方法，如图2所示。首先，以恒电流充电至预定的电压值，然后，改为恒电压完成剩余的充电。一般两阶段之间的转换电压就是第二阶段的恒电压；2.三阶段充电法。在充电开始和结束时采用恒电流充电，中间用恒电压充电。当电流衰减到预定值时，由第二阶段转换到第三阶段；（三）恒压充电法。充电电源的电压在全部充电时间里保持恒定的数值，随着蓄电池端电压的逐渐升高，电流逐渐减少。由于充电初期蓄电池电动势较低，充电电流很大，随着充电的进行，电流将逐渐减少，因此，只需简易控制系统。这种充电方法电解水很少，避免了蓄电池过充。但在充电初期电流过大，对蓄电池寿命有一定的影响。 随着经济大时代的到来，各种工业兴旺发达，对搬运设备要求越来越高，早期燃油叉车的诞生便为工业的发展节省了大量人力，一直延续至今，随着环境日益恶劣，国家对仓储、生产规范化，蓄电池叉车应知而生，作为车辆核心的叉车蓄电池，替换了排放量、污染大的柴油叉车，带动了新兴能源产业的发展，各种配套附件及材料厂迅速崛起，现在使用的电动叉车蓄电池基本上都是铅酸电池，那么这种电池具有什么样的特点呢？这才是人们*为关注的，毕竟如果没有很不错的电池，就没有办法保证电动叉车长期运转，更没有办法保证工作的顺利进行。所以说就电动叉车蓄电池来说，应当比较省电，长期使用，这才是*关键的。其实铅酸电池就具有这样的优势。 一方面是铅酸电池的价格相对来说比较低，一次性的投资非常少，也可以受到大多数人的接受，毕竟对于大多数使用电动叉车的人来说，使用昂贵的电动叉车蓄电池，根本就没有那种必要。另外一方面就是充放电的时间比较短，在停止工作的时候，*好将蓄电池中的电量全部放空，这样才能更好的保障蓄电池的使用寿命，其充电过程也比较短，根本就不会耽误工作的进度。 蓄电池由厂家发出直至安装，时间跨度一般都很大。之前虽然对蓄电池均有初始充电措施，但由于蓄电池有自放电效应，以时间来算，存储8个月就可以耗费蓄电池容量的一半，显然不能满足现场运行需要。我们在对蓄电池安装以后，需进行必要的维护，这就需要对蓄电池进行初充电。 通常的做法就是“两充一放”，即初充电，放电，补充电。在补充电完成之后，蓄电池就可以以浮充电的方式投入运行。补充电；基本的充电方法是，先用恒压充电法对蓄电池进行补充电，初次充电应根据产品技术规定进行，充电电流限在不大于10h放电率电流为准。当蓄电池单瓶电压升至2.25V以上，电流维持在0.5―1A、并维持3小时不变时视为充足电；蓄电池进行大容量放电后应及时再充电，间隔时间不应超过24h。放电的过程以10h放电率电流计算，以110V、420Ah容量蓄电池组为例，即以42A电流进行放电，放电过程需严密监控蓄电池单体电压，当其中有任一节蓄电池单节电压降至1.80V时，或整组电压不低于93.6V时，即应终止放电，核算蓄电池容量。放电过程中，不宜采用临界标准，厂家保护装置一般设置整组电压标准为不低于94V，这就需要我们对单体电压的测量更加精确，特别在放电的后2个小时，测量人员需每隔半个小时测量一次单体及整组电压，在放电临近10h的*后半小时，更应该重点监控电压*低的3～5节单体电压值，防止蓄电池电压陡降而损坏电池；工程实践中，我们通常采用大电流法，即恒流法对蓄电池组进行补充电。充电时间仍按10h计算，充电电流基本以此值为佳，绝不能大于0.3c，过大或过小电流充电都会影响蓄电池的使用寿命。在巡查过程中，单节电池电压不超过2.6V，整组电压不大于135.2V为准，当蓄电池充电满10h，每节电池电压为2.25V左右，为电池饱和状态。切换为浮充方式即可投入运行。4.均恒充电。当蓄电池完成“两充一放”之后，我们可以认为蓄电池施工过程中一个维护周期的结束，但蓄电池长期稳定运行的任务远远没有结束。下面的任务就落到了电厂变电的维护人员身上。 DA-500 is the lead-acid battery forklift, forklift battery 80V500Ah, nameplate model most Tags: 40-5DB500, 40-5PZB500, 40-D-500, DA-500, 40-5PBS500; applicable Heli forklift, Hangzhou forklift, Baoli forklift, forklift, forklift, JAC Tai Lifu Coase forklift, Liugong forklift, forklift, forklift, Dalian Connaught Wuxi Cape forklift 3 tons to 3.5 tons of forklift, have deep circulation ability more than 1000 times, large output current is stable. Forklift battery charging, due to the limitations of the conditions, the general use of conventional charging method. Conventional charging generally has the following 3: (a) constant current charging method. The charging current remains constant during the charging process, called the constant current charging, constant current charging method is used to adjust the charging device output voltage or change resistors in series with the battery charging method, keep the current constant; (two) phase charging method. This method consists of two stages and three stages of charge: the 1 phase of the two method. Constant current and constant voltage combination of fast charging method, as shown in figure 2. First, a constant current is charged to a predetermined voltage value, and then a constant voltage is used to complete the remaining charge. The conversion voltage between the two stages is the constant voltage of the second stage; the 2 stage of the three phase charging method. At the beginning and the end of the charging using constant current, constant voltage charging. When the current is attenuated to a predetermined value, the second phase is converted to the third stage; (three) the constant voltage charging method. The voltage of the charging power supply keeps a constant value in the whole charging time, and the current decreases gradually with the increase of the terminal voltage of the battery. Due to the low cost of the battery, the charging current is very large, with the charge, the current will be gradually reduced, therefore, only a simple control system. This kind of charging method is very little, so it can avoid overcharge. But in the initial charging current is too large, the battery life has a certain impact.
With the arrival of the era of economy, industrial prosperity, the higher the handling equipment requirements and save a lot of manpower and fuel for the early birth of forklift industry, continues today, with the increasingly harsh environment, the state of storage, standardized production, storage battery forklift should know. And as a forklift battery vehicle the core of the replacement of emissions, pollution of diesel forklift, led to the development of new energy industry, all kinds of accessories and materials factory to rise rapidly, now use electric forklift batteries are basically lead-acid batteries, the battery has the characteristics of what? This is the most concerned about, after all, if there is no very good battery, there is no way to ensure long-term operation of electric forklifts, there is no way to ensure the smooth progress of the work. So on the electric forklift battery, it should be more power, long-term use, this is the most critical. In fact, lead-acid batteries have such advantages. On the one hand is the lead-acid battery price is relatively low, the one-time investment is very small, can also be accepted by most people, after all, for most people who use electric forklift, electric forklift battery expensive, there is no kind of necessary. On the other hand is the charge and discharge time is short, in time to stop work, will be the best battery in the battery all empty, so as to better guarantee the service life of the battery, the charging process is relatively short, do not delay the progress of the work. Battery issued by the manufacturers until the installation, the time span is generally large. Although before charging the battery with the initial measures, but due to the battery self discharge effect, in terms of time, half of the storage 8 months can save battery capacity, obviously can not meet the needs of field operation. After the installation of the battery, we need to carry out the necessary maintenance, which requires the initial charge of the battery.
The usual practice is the "two charging and discharging", that is, the initial charge, discharge, add electricity. After the completion of the supplementary power, the battery can be put into operation in the form of floating charge. The basic charging method is to use a constant voltage charging method for the battery to recharge, the initial charge should be based on the technical requirements of the product, the current limit is not greater than the discharge rate of 10h. When the battery voltage rises above 2.25V single bottle, the current is maintained at 0.5 - 1A, and maintain a constant power of 3 hours as sufficient electricity; battery discharge should be recharged after a large capacity, the interval should not exceed 24h. The discharge process with 10h discharge rate current calculation, with 110V, 420Ah capacity battery as an example, the 42A current discharge, the discharge process need to closely monitor the battery voltage when the battery, which have either single voltage to 1.80V voltage, or the whole group is not less than 93.6V, shall terminate discharge. Check the battery capacity. In the discharge process, not the critical standard, manufacturers generally set the entire set of voltage protection device is not less than the standard 94V, which we need to measure the voltage of single is more accurate, especially in the discharge after 2 hours, measurement personnel need to measure once every single cell and whole group in the discharge voltage for half an hour. Near 10h the last half hour, should focus on monitoring the minimum voltage of 3 ~ 5 single voltage value, the battery voltage drop to prevent damage to the battery; in practice, we usually adopt large current method, namely the constant current method to supplement the power of the battery group. Charging time is still calculated according to 10h, the charging current based on this value is good, must not be greater than 0.3C, too large or too small current charge will affect the storage
