Excavator battery is a device for storing electric energy. Once the external load is connected or the charging circuit is connected, it starts the energy conversion process. During the discharge process, the chemical energy in the battery is converted into electrical energy. During charging, electrical energy is converted into chemical energy. According to the function of the diesel engine starting control system and the basic working principle of the circuit, the reason why the starter cannot start may be caused by battery failure, starter failure and diesel engine electronic control system failure. The power supply system of the excavator uses the battery as the power supply and has a charging system. The alternator is driven by the engine to generate power. The charging system supplies power to all electrical equipment and charges the battery. The daily maintenance of excavator is very important to improve the working efficiency and prolong the service life of excavator. During daily maintenance of excavator, special attention shall be paid to the replacement of engine oil, diesel filter element, oil filter element, air filter element and hydraulic oil return filter element. However, one point that may be easily overlooked is the maintenance of excavator battery.
In addition to checking and replenishing the battery replenishment fluid, there are also many aspects that need attention during the daily use of the excavator.
Some excavators install the battery in the tool box. If there are too many tools in the toolbox, it is likely that the positive electrode of the battery will be grounded due to the movement of the tools. Therefore, it is better to have protective devices for the battery. The upper part of the battery is covered with insulating materials such as plastic covers, which can not only discharge water, but also prevent metal objects from colliding with the positive electrode and causing grounding.
When the excavator is idling, the generator output voltage is low. At this time, the battery is not charged or charged too slowly. If the excavator is idling for a long time, turn on the air conditioner, listen to songs or turn on the work lights. Almost all the electricity stored in the battery is used, and it is easy to cause battery loss. These behaviors should be avoided as much as possible.
Some excavators may be difficult to start. However, due to the large current of the engine starting motor, long-time starting will greatly reduce the service life of the battery. Therefore, the ignition time of each time shall not exceed 5 seconds. If the ignition is not successful, the ignition shall be conducted at an interval of more than 15 seconds. In addition, when the excavator is parked for a long time, it is best to remove the negative terminal pile head of the battery. Because the battery is self discharging when the excavator is not working. Although the speed of power consumption is very slow, long-term parking may lead to battery loss, and it is difficult to ignite when used again.
Although lead-acid batteries are not as convenient as maintenance free batteries. However, due to its stable voltage and low price, it is still used by many users. In fact, like the three important parts of the excavator, the battery also needs daily maintenance. Therefore, we hope to pay more attention to the daily maintenance of the battery.
