(1) If the positive and negative plates of the welding plate can not be used anymore, the plates must be rewelded: 1 Select the plates. According to the height of the battery case, the plates are selected and the oxides on the plate ears are eliminated with a wire brush or a small file. 2 Adjust the height of the weld (comb plate). Measure the distance from the bottom edge of the battery container to the lower edge of the terminal hole on the battery cover, adjust the height of the comb plate according to the measured distance, and determine the position of the terminal according to the distance between the inner edge of the electric column hole and the two ends of the battery cover. 3 Welding. Plates are usually welded with carbon rods, and 8 to 12 volt step-down transformers are used as the power supply (it is also possible to replace them with large-capacity batteries, but they cannot discharge the batteries too much). When welding, the temperature should be controlled so that even if the lead is melted, the lead does not flow down from the comb plate, resulting in excessive levels of flat and surface cinder. The tip of the charcoal rod should be deep into the lead, but it should not come into contact with the comb-shaped pole. Then slowly move the charcoal rod until it is well welded. Remove the plate assembly and remove the carbon residue and the flowing lead from the plate assembly welding. grain. Acetylene welding is best when conditions are available. It is not only efficient but also of good welding quality. Under difficult conditions, if there is no such equipment, a larger soldering iron can be used for soldering. Although this method is relatively backward, it can still solve problems under difficult conditions. (2) Insert a separator. Cross the positive and negative plate groups and insert the separator from the middle. If there is a groove, the grooved surface faces the positive electrode. Glass fiber separators are used in conjunction with other separators. Glass fiber separators are used in conjunction with other separators. Glass fiber separators should be placed on the positive electrode. (3) Put the plate group into the shell. The positive pile is located on the right side facing the factory sign. The plate group should not be loosened into the shell. Put a rubber ring around the terminals, cover the cover, and plug the asbestos rope or paper between the cover and the shell to prevent the asphalt seal from flowing into the shell. (4) Welding terminal and connecting plate Put the connecting plate on the terminal, and use the carbon rod to weld and melt the terminal head above the connecting plate to make the terminal and the connecting plate melt into one. (5) Sealing the bituminous sealing glue to heat the bituminous sealing glue. When bubbles and yellow smoke appear, use a steel spoon to pour the molten bitumen sealant into the groove between the shells. After cooling, remove the excess bitumen seal. Material, and use hot red iron or iron shovel to seal the asphalt sealant.
