If the diesel generator set is not used for a long time, it is necessary to prevent 'stop damage'

Most of the diesel generator set failures are caused by the unit being in a static state for a long time. The various materials of the unit itself will undergo complex chemical and physical changes with the oil, cooling water, diesel, air, etc. This is mainly manifested in two aspects, which are summarized as follows : The filtration capacity of the filter decreases. The filter plays a role in filtering diesel, engine oil or water to prevent impurities from entering the body. Oil dirt and impurities are also inevitable in diesel, so during the operation of the unit, the filter plays a role. important role, but at the same time these oils or impurities are also deposited in On the filter wall, the filtration capacity of the filter will be reduced, and there will be too much sedimentation, and the oil circuit will not be smooth. In this way, when the oil engine is running under load, it will go into shock due to the inability to supply oil (like a person lacking oxygen). Therefore, during normal use of the generator set Among them, the editor of the diesel generator public platform recommends: 1. Every 500 for commonly used units Replace the third filter every hour; secondly, replace the third filter of the backup unit every two years. The water circulation in the cooling system water pipeline is not smooth. 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. Whether the water pipe joints are in good condition, whether there are leaks in the water tank and water channels, etc. If the cooling system is faulty, it will cause The consequences are: 1. The cooling effect is not good, causing the water temperature in the unit to be too high and shutting down; 2. The water tank leaks, causing the water level in the water tank to drop, and the unit will not work properly (in order to prevent the water pipes from freezing when using the generator in winter, it is recommended to cool down as much as possible. water heater installed in the system). As a backup power source, many diesel generator sets cannot avoid being in a standby state most of the time. Therefore, in order to prevent the above phenomena in the unit, routine maintenance methods must be strengthened.
