In the daily operation of diesel generator sets, the importance of starting the battery as the pacemaker of the entire system is self-evident.A healthy and efficient starting battery can ensure that the generator set responds quickly at critical moments, providing a solid guarantee for all kinds of emergency or conventional power needs.However, many users often ignore the maintenance and maintenance of the starter battery, which leads to reduced battery performance, shortened life, and even affects the overall operating efficiency of the generator set.Talk to you in depth about the maintenance secrets of the starting battery of the diesel generator set, to help you start from scratch and gradually master the maintenance skills of this key link.
The starter battery, as the name suggests, is the source of energy during the start-up of a diesel generator set.When the generator set receives the start-up signal, the start-up battery releases the stored electrical energy to drive the starter to rotate, and then drives the engine crankshaft to rotate to realize the start-up of the unit.Therefore, the performance of the starting battery directly determines whether the generator set can start smoothly and the speed of the starting speed.Once the starting battery fails or the performance drops, it will directly affect the reliability and stability of the generator set.
The starting batteries commonly used in diesel generator sets mainly include two categories: lead-acid batteries and lithium batteries.Among them, lead-acid batteries occupy a dominant position in the market because of their low cost, mature technology, and easy maintenance.Lithium batteries, on the other hand, with their high energy density, long life, low self-discharge rate and other characteristics, have gradually become the new favorite of the high-end market.
No matter what type of starter battery it is, it needs regular maintenance and maintenance to ensure its stable performance and extended life.
1. Check the appearance of the battery regularly
Observe the battery housing: Check the battery housing for cracks, deformation or leakage.If found, the battery should be replaced immediately to prevent the electrolyte from corroding the surrounding parts.
Clean the surface of the battery: Use a clean cloth or sponge to gently wipe the surface of the battery to remove dust, oil and corrosion.Be careful not to use corrosive cleaners or sharp tools to avoid damaging the surface of the battery.
2. Monitor battery voltage and electrolyte
Voltage check: Use a multimeter to regularly check the voltage value of the battery.Under normal circumstances, the voltage of the starting battery should be kept near the nominal value (for example, the voltage of the 12V battery should be around 12V).If the voltage is too low, it may be caused by battery loss or internal failure, and the battery needs to be charged or replaced in time.
Electrolyte inspection: For lead-acid batteries, the liquid level height and color of the electrolyte need to be checked regularly.The liquid level should be kept between the upper and lower tick marks, and an appropriate amount of distilled water should be added when insufficient (do not add tap water or electrolyte).At the same time, observe the color of the electrolyte. If it becomes cloudy or dark, it may be corrosion or aging inside the battery, which needs to be dealt with in time.
3. Keep the battery connected well
Check the battery cable: Regularly check whether the battery cable is loose, corroded or damaged.If found, the connection cable should be fastened or replaced in time to ensure that the electrical connection between the battery and the generator set is good.
4. Regular charging and maintenance
Regular charging: Even if the generator is not in use for a long time, the start-up battery should be charged regularly to keep the battery active.When charging, a dedicated charger should be used and operated in accordance with the requirements of the manual.
Avoid overcharge and over discharge: overcharge and over discharge will cause damage to the battery.Therefore, during the charging and discharging process, the range of voltage and current should be strictly controlled to avoid exceeding the rated value of the battery.
5. Storage and transportation precautions
Storage environment: The starting battery should be stored in a dry, ventilated and non-corrosive gas environment.Avoid direct sunlight and high temperature environments to avoid performance degradation or damage caused by excessive internal temperature of the battery.
Transportation safety: When transporting and starting the battery, make sure that the battery is firmly fixed to avoid severe vibration and collision.At the same time, pay attention to the polarity direction of the battery to prevent short circuit or reverse connection.
6. Emergency response and troubleshooting
Emergency response: If you encounter an emergency situation such as battery leakage or fire, you should immediately cut off the power supply, use a dry powder fire extinguisher to extinguish the fire, and quickly evacuate the surrounding personnel.
Troubleshooting: When the generator set cannot be started, first check whether the starting battery is normal.If the battery voltage is normal but the unit cannot be started, it may be caused by internal battery failure or connection line problems.At this time, tools such as multimeters should be used for troubleshooting and handling according to specific circumstances.
As an important part of a diesel generator set, the starter battery cannot be ignored in its maintenance and maintenance work.Through regular inspection, monitoring of voltage and electrolyte, maintaining a good connection, regular charging and maintenance, and paying attention to storage and transportation safety and other measures, we can effectively extend the service life of the starter battery and improve its performance stability and reliability.
