Will It Be Harmful If You Don't Use Diesel Generators for a Long Time

Mar. 11, 2019

Speaking of standby diesel generators, it is to "Maintain an army for a thousand days to use it for an hour." Therefore, most of the spare diesel generator sets are spared after being purchased. If the mains supply is normal, the diesel-diesel generator set is basically unused and is in a long-term idle state.

Doing so will reduce the useful life. The standby diesel generator set has been stopped, mostly because the diesel generator set is static for a long time, and various materials of the unit itself will undergo complicated chemical and physical changes with oil, cooling water, diesel oil and air. The first is the filtration system in the diesel generator set. The filtration system mainly filters organic oil and air. If it is parked for a long time, impurities in the air, oil stains, etc. will precipitate or adhere to the filter material. Unobstructed, when the generator set is operated in such an environment, black smoke will occur, mainly due to insufficient combustion and insufficient oxygen.


Followed by the water tank, the principle is the same as the filter material. What problems will occur when there are too many impurities in the water tank? It will directly cause the diesel generator set to stop running, mainly because the temperature of the water tank is too high, the temperature cannot be cooled down, and there is the northeastern region of China. The temperature in winter is too low and it is easy to freeze the pipeline. Daily maintenance of the diesel generator set is necessary, which can extend the life of the machine for a long time, and finally bring the user a saving effect.


1. The backup diesel generator filter has a reduced filtration capacity.


The diesel generator filter filters the diesel, oil or water to prevent impurities from entering the body, so the filter plays an important role in the operation of the unit. However, these oils or impurities will slowly deposit on the wall of the filter, resulting in a decrease in the filter capacity of the filter, and a serious oil passage. In this case, the diesel generator set will be shocked by the inability of the oil to supply (like human hypoxia). Therefore, in order to ensure the normal operation of the diesel generator set, Huaquan diesel generator set is recommended to customers, the common unit replaces the three filters every 500 hours, and the standby unit replaces the three filters every two years.


2. The cooling system of the backup diesel generator set has a poor water circulation.


The water pump, water tank and water pipeline have not been cleaned for a long time, resulting in poor water circulation and reduced cooling effect. If the cooling system is faulty, it will lead to the following consequences: 1. The cooling effect of the diesel generator set is poor, and the water temperature in the unit is too high, resulting in shutdown; 2. The water tank of the diesel generator set will leak, the water level in the water tank will drop, and the unit will not work normally.


So, what is the significance of the normal maintenance and maintenance of diesel generator sets?


1. The diesel generator set is used as a backup power source, a self-supplied power source, and an emergency power source. It needs to be able to provide power in time when people need it. If it cannot be started, it will lose its meaning, even if the price of the diesel generator set. It is also a waste. Practice has proved that strengthening maintenance is an effective way to ensure that the generator set can be powered in time.


2. The genset is not in use or in use for a long period of time. The components, diesel, engine oil and cooling water of the unit will undergo certain qualitative changes or wear. This is also the need to restore the normal state of each component and consumables through maintenance.


3. Generator sets that have been put on hold for a long time, even if the price of the generator set is high, it needs to be maintained. For example, if the battery is turned on for a long time without maintenance, the electrolyte is not replenished in time, or the floating charger needs manual operation, and the operator neglects the regular operation, which will cause the battery to fail to meet the requirements.


When the diesel generator set is not used for a long time, the air inlet should be sealed in advance to prevent dust from polluting the air filter element, causing blockage for a long time, the power switch is in an open state, and the antifreeze is added as much as possible to prevent rust or freezing. The battery is disconnected from the circuit, and the battery is periodically charged to prevent the battery from losing power. Finally, the oil is stored. The oil is parked for too long, and it is necessary to see if it is sticky or deteriorated.
