The daily maintenance and repair of the battery is extremely important. Generally, corrosion and liquid leakage are easy to occur, and attention shall be paid to keep it clean. This article will explain the pile head and shell cover of storage battery in winter, for reference only.
The positive and negative electrode pile heads of the excavator's battery are prone to poor contact or power failure in case of loose line connection or electrochemical corrosion. Therefore, it is recommended to inspect and clean them on a quarterly basis. During battery maintenance, it is recommended to use standby battery for connection. The connection is to prevent power failure, so as not to affect the set value of electrical instruments on the excavator. When the pile head is found to be worn and uneven during inspection, it can be simply polished with sandpaper. In addition, yellow and white chemical corrosives may appear near the shell cover and pile head of the battery after each period of use. They are sulfuric acid compounds with strong corrosiveness and resistance, which will affect the charge and discharge of the battery and lead to poor conductivity of the battery. Based on the principle of acid-base neutralization, the corrosive substances on the shell cover can be wiped off with alkaline solution such as alkaline water or soda water with a dilution ratio of 1:10. If green corrosion is found at the connection of pile head, it can be washed away with boiled water, wiped with dry rag and dried with air duct. In order to prevent the reappearance of corrosive substances affecting the performance of the battery, special anti oxidant for the battery can be coated. Regular cleaning of the battery can reduce the impact of electrochemical corrosion on the battery, ensure the service life of the battery, and effectively avoid the failure of engine startup.
