Diesel generator battery is the power supply equipment for starting electrical
machinery operation. When the diesel engine is started, it is required that the
battery can supply low voltage and high current (200~600A) for starting
electrical machinery in a short time. When the diesel engine is in low
speed or parking, the voltage output by generator is insufficient or stops
working, the storage battery can supply the electric current for the electrical
equipment of the diesel engine.
What is
the function of the Battery?
The Battery is the storage
device for the energy supplied by the battery chargers. It stores this energy
by converting the electrical energy to chemical energy and then to electrical
energy. It supplies power to the cranking motor to start the engine. It supplies
the extra power necessary when the engine's electrical load exceeds the supply
from the charging system. It also acts as a voltage stabilizer in the
electrical system, where it evens out voltage spikes and prevents them from
damaging other components in the electrical system.
It
can be seen that the storage battery plays an important role in diesel generator. For the battery
maintenance, how much do you know?
1. When the storage battery is
in use, it must be installed firmly. Make sure the wiring clip keeps a good
contact with the battery terminal. To avoid oxidation of the wiring terminal,
its surface should be covered with a thin layer of butter.
2. In general, the wiring
terminal of the storage battery is marked with “+” or “-“ symbol. If there is
no marking, you can use the multi-meter to measure the polarity of the battery.
3. The starting time of diesel
engine is not allowed to exceed 10 seconds. Besides, the interval time must be
controlled more than 2 minutes when booting second time. Avoid the battery
continuous discharge time is too long that will make the pole plate out of
shape due to overheating, which will result in short circuit or active material
shedding and reduce the capacity of the storage battery.
4. Inspect the exhaust hole on
the sealing cover which must be kept unblocked at any time to prevent blocking
to cause the battery burst.
5. Regularly inspect the
battery electrolyte level, generally, it is higher than the pole plate top
surface 10-15mm. If you find it is abnormal, you should adjust to use dilute
sulphuric acid or distilled water. (River water, well water and concentrated
sulfuric acid are not allowed to use.)
6. Keep the battery surface
clean. If there is dust or acid liquor, you should timely clean it with
distilled water or pure water.
7. When the battery is used for
a long time, the internal electrolyte is missing, you should timely add
distilled water inside the battery to prevent pole plate oxidation, otherwise,
it will influence battery capacity.
8. When the diesel engine is
not working for a long time, you should periodically start the engine to charge
the battery or charge the battery with a special charger.
9.
When the battery is charged, the sealing cover should be screwed off. The
positive and negative electrodes of the charger should be respectively
connected with the positive and negative electrodes of the battery. Generally,
the charging method of the battery is divided into two types: constant current
charging and constant voltage charging.
10.
When using the battery in cold area, you should pay attention to thermal
insulation. In addition, you should properly increase electrolyte specific
gravity to prevent freezing. When the ambient temperature is below -40°C, the
electrolyte density should be increased to 1.30-1.32 (The measured value at 20°C).
11.
When the battery is used in low temperature environment, the discharge
performance of the battery is poor and the torque of the starting electrical
machinery is increased, if the discharge capacity of a pair of battery is
insufficient, it can be connected in parallel with two batteries. Also, keep
24V voltage constant so as to increase battery capacity.
12.
If you find the battery separator and battery cover are damaged, it shall be
repaired or replaced by a professional unit.
