If the battery capacity decreases, there may be several reasons: 1. The electrolyte of the entire battery generally has a low density. Use a hydrometer to test and verify that you can drain the electrolyte from the battery, wash it twice; with distilled water, then add a specific gravity of 1.28. The standard solution (electrolyte, not distilled water) can be used after eight to ten hours of charging; 2. The battery plates are severely vulcanized. 3. The battery is in a state of power loss; for a long time; 4. Overfilling of distilled water overflow and loss of sulfuric acid causes low density, the electrolyte height exceeds the plate by 10-12mm and cannot be overfilled. During loading, the metal components will be filled. corroded and sulfuric acid will be lost, reducing the density; 5. The car's generator breaks down, resulting inhas a low load capacity.
How to maintain emergency generators?
Diesel generator battery maintenance methods:
1. Diesel generator batteries that have been stored for a long time should be properly charged before use to ensure normal diesel operation. generator battery capacity.
2. Normal operation and charging will cause some of the water in the diesel generator battery to evaporate, requiring frequent refilling of the diesel generator battery. Before filling, the dirt around the filling port must first be cleaned. prevent it from falling into the battery compartment of the diesel generator, then open the filling port and add an appropriate amount of distilled or purified water. Do not overfill the scale on the battery plate of the diesel generator, otherwise the battery willA diesel generator will discharge. . /During charging, the internal electrolyte will spurt out from the overflow hole of the filling port, causing corrosion and damage to surrounding objects and the environment. The actual battery capacity of the diesel generator can be detected through a hydrometer.
3. Avoid using the diesel generator battery to start the unit at low temperatures. The capacity of the diesel generator battery will not be able to work normally in low temperature environments, and long-term discharge may cause the diesel generator battery to deteriorate. failure.
4. The emergency generator diesel generator battery should be maintained and charged regularly and may be equipped with a floating charger.
5. Use a damp cloth to scrub the exterior of the diesel generator battery and wipe off dust, oil, white powder and other dirt that can easilyly cause leaks on the panel and pile heads (i.e. the positive). and negative poles). In this way, if the diesel generator battery is cleaned frequently, the acid-etched white powder will not accumulate on the pile head and its service life will be longer.
6. Open the diesel generator battery water filler cover and check whether the water level is at the normal position. Generally, there are upper and lower limit marks on the battery side of the diesel generator for reference. If the water level is found to be lower than the lower mark, distilled water should be added. If distilled water cannot be obtained immediately, filtered tap water can be used in an emergency. Don't add too much water, the standard is to add some in the middle of the top and bottom markings.
7. Check if the battery charges normally. If you have an ammeter at trois usages, measure the voltage at both poles of the diesel generator battery after starting the engine. It must exceed 13 V to be considered normal. If you find that the charging voltage is too low, you should ask a professional to check the charging system. If there is no three-function ammeter, you can carry out a visual inspection: after starting the engine, open the water filler cover of the diesel generator battery and see if there is bubbles in each small grid. The normal situation is that bubbles are constantly coming out of the water.And the more the oil bubbles, the more it will bubble; If you see no bubbles, there is probably a problem with the charging system. Particular attention should be paid to the fact that hydrogen will be generated during this inspection, so do not smoke during the inspection to avoid danger.
Based on maintenanceon a daily basis, maintenance can be carried out every six months or a year
1. Perform a complete inspection of water, electricity, oil and gas. , etc. generator set Check to confirm if the unit is normal;
2. Test the unit without load for 5-10 minutes to judge the working condition of the unit by listening; , see, feel, etc. ;
3. Replace the air filter, diesel filter, engine oil, engine oil filter, water filter, oil-water separator filter element and other consumables;
4. Replace the radiator reservoir coolant and water tank treasure;
< p>5. Add battery fluid or distilled water;6. After completing maintenance, check the generator again and clean it. ;
7. Dry test. It takes 5-10 minutes to record the unit's performance parameters, offer reasonable suggestions and acceptter customer acceptance.
