What should you pay attention to when using and maintaining the starting battery of a 400kw diesel generator

For safety reasons, you should wear an acid-proof apron and a mask or protective goggles when maintaining the battery. Once the electrolyte accidentally splashes on your skin or clothing, rinse it immediately with plenty of water. The battery is dry when it is delivered to the user. Therefore, electrolyte with the correct specific gravity (1:1.28) that has been evenly mixed should be added before use. Unscrew the top cover of the battery compartment and slowly inject the electrolyte until it is between the two scale lines on the upper part of the metal piece and as close to the upper scale line as possible. After adding it, please do not use it immediately. Let the battery rest for about 15 minutes.

When charging the battery for the first time, it should be noted that the continuous charging time should not exceed 4 hours. Charging time too long will cause damage to the service life of the battery. When one of the following situations occurs, the charging time is allowed to be extended appropriately: the battery is stored for more than 3 months, the charging time can be 8 hours, the ambient temperature continues to exceed 30°C (86°F) or the relative humidity continues to be higher than 80%, the charging time is 8 hours. If the battery is stored for more than 1 year, the charging time can be 12 hours.

At the end of charging, check whether the electrolyte level is sufficient. If necessary, add standard electrolyte with the correct specific gravity (1:1.28).

The generator set direct sales center website reminds: When charging the battery, you should first open the battery filter cap or vent cover, check the electrolyte level, and adjust it with distilled water if necessary. In addition, in order to prevent long-term closure of the battery compartment, the dirty gas in the battery compartment cannot be released. Drain in time and avoid condensation of water droplets on the inner top wall of the unit. Pay attention to opening special ventilation holes to facilitate proper air circulation.

Tips on maintenance of diesel generator battery

Diesel generator set is a power supply equipment that uses a diesel engine as the prime mover to drive a synchronous generator to generate electricity. This is a power generation device that starts quickly, is easy to operate and maintain, has low investment, and has strong adaptability to the environment.

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. 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 compartment, and then remove the filling port. Open it and add an appropriate amount of distilled or purified water. Do not overfill. 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 corrosion to surrounding objects and the environment. destroy.

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. 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:

, 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 someone 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.

Second, open the battery water 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 it is found that the water level is 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.

Third, use a damp cloth to scrub the outside of the battery, and wipe away dust, oil, white powder and other contaminants that may easily cause leakage on the panel and pile heads. 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.
