Diesel generator set battery maintenance

When the battery of a diesel generator set is not in use for a long time, appropriate charging must be given before use to ensure the normal capacity of the battery. (The actual capacity of the battery can be detected by a hydrometer) Normal operation and charging will cause some water in the battery to evaporate, which requires frequent rehydration of the battery. Before rehydration, first clean the dirt around the filling port to prevent it from falling into the battery grid. Then open the filling port and add an appropriate amount of distilled water or pure water. Do not add it too much (using the scale of the battery plate as the standard). Otherwise, when the battery is discharged/charged, the electrolyte inside the diesel engine will gush out from the overflow hole of the filling port, causing corrosion and damage to surrounding objects and the environment. Avoid starting the battery at low temperatures. The battery capacity will not be output normally under low temperature environments, and long-term discharge may cause battery failure (cracking or explosion). The battery of the backup generator set should be maintained and charged regularly and can be equipped with a floating charger. Tips for maintaining battery of diesel generators: 1. Use a wet cloth to wipe the outside of the battery and wipe the dust, oil, white powder, etc. on the panel and pile head (i.e. the positive and negative pole heads) clean. In this way, the battery will not accumulate white acid-etching powder on the pile head, and its service life will be longer. 2. Open the battery and add water cap to see if the water level is in the normal position. Generally, there are upper and lower limit markings on the side of the battery for your reference. If you find that the water level is lower than the lower mark, you must add distilled water. If you cannot get the distilled water at once, you can filter tap water for emergency response. Do not add too much water, the standard is to add it to the middle of the upper and lower marks. 3. Check whether the battery is charging normally. If you have a three-purpose meter, after starting the engine, measure the voltage at the poles of the battery, which must exceed 13V to be considered normal. If you find that the charging voltage is too low, you need to ask a professional to inspect the charging system. If there is no three-use meter, you can use visual inspection method: after the engine is started, open the battery and add water cap to see if there are any bubbles in each small grid. The normal situation is that bubbles keep coming out of the water, and the more you get, the more you will get; if you find that there is no bubble, it is likely that there is something wrong with the charging system. It is particularly important to note that hydrogen will be produced during this inspection, so do not smoke during inspection to avoid the risk of explosion and fire. 1. Daily maintenance: 1. Check the working daily report of the diesel generator. 2. Check the diesel generator: oil level, coolant level. 3. Daily check whether the diesel generator is damaged or leaky, and whether the belt is loose or worn. 2. Weekly maintenance: 1. Repeat the daily diesel generator inspection. 2. Check the air filter and clean or replace the air filter core. 3. Release water or sediment in the fuel tank and fuel filter. 4. Check the water filter. 5. Check the starting battery. 6. Start the diesel generator and check if there is any impact. 7. Use an air gun and clean water to wash the heat sink at the front and rear ends of the cooler. Air filter
