Diesel generator battery maintenance

When the battery of the diesel generator set has not been used for a long time, it must be properly charged before use to ensure the normal capacity of the battery. (The actual capacity of the battery can be detected through a hydrometer) Normal operation and charging will cause some water in the battery to evaporate, which requires frequent refilling of the battery. Before refilling, clean the dirt around the filling port to prevent it from falling into the battery compartment, and then remove the filling port. Open and add appropriate amount Do not overfill distilled or purified water (based on the scale on the battery plate). Otherwise, when the battery is discharging/charging, the electrolyte inside the diesel engine will gush out from the overflow hole of the filling port, causing damage to surrounding objects. , Environmental corrosion damage. Avoid using the battery to start the unit at low temperatures. The battery capacity will not be output normally in low temperature environments, and long-term discharge may cause battery failure (cracking or explosion). The batteries of the standby generator set should be maintained and charged regularly and can be equipped with a float charger. Tips for diesel generator battery maintenance: 1. Use a damp cloth to scrub the outside of the battery, and wipe clean the dust, oil, white powder and other dirt that can easily cause leakage on the panel and pile heads (i.e. the positive and negative poles) . If the battery is scrubbed frequently in this way, white acid-etched powder will not accumulate on the pile head of the battery, and its service life will be longer. 2. Open the battery water filling cap and check whether the water level is at the normal position. Generally there will be upper and lower limit markings on the side of the battery for your reference. If the water level is found to be lower than the lower mark, distilled water must be added. If distilled water cannot be obtained at once, filtered tap water can be used as an emergency. Do not add too much water, the standard is to add it to the middle of the upper and lower markings. 3. Check whether the battery is charging normally. If you have an ammeter, after starting the engine, measure the voltage on both poles of the battery. It must exceed 13V to be considered normal. If you find that the charging voltage is too low, you need to ask a professional to check the charging system. If there is no three-purpose ammeter, you can use visual inspection: after starting the engine, open the battery water filling cap and see if there are bubbles in each small cell. The normal situation is that bubbles will continue to bubble out of the water, and the more oil will bubble out, the more oil will bubble up; if you find that there is no bubble, there is probably something wrong with the charging system. Special attention should be paid to the fact that hydrogen will be generated during this inspection, so do not smoke during the inspection to avoid the risk of explosion and fire. 1. Daily maintenance: 1. Check the diesel generator daily work report. 2. Check the diesel generator: oil level and coolant level. 3. Check the diesel generator daily for damage, leakage, and whether the belt is loose or worn. 2. Weekly maintenance: 1. Repeat daily diesel generator inspection. 2. Check the air filter, clean or replace the air filter element. 3. Drain the 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 whether there is any influence. 7. Use an air gun and clean water to clean the heat sinks at the front and rear ends of the cooler.
