What Aspects of Diesel Generator Sets Need to Be Maintained?

Dec. 13, 2021

What do you think the diesel generator set needs to be maintained? Check and maintain the starting battery of the set: If the battery is left unmaintained for a long time, the electrolyte cannot be replenished in time after volatilization, and there is no starting battery charger, and the battery will be discharged after a long time. Reduced, or the used charger requires manual equalization and floating charge switching on a regular basis. The battery power cannot meet the requirements due to negligence and failure to perform the switching operation. In addition to configuring high-quality chargers, necessary inspection and maintenance are necessary to solve this problem. . Prevent water ingress. Due to the condensation of water vapor in the air due to temperature changes, it forms water droplets that hang on the inner wall of the fuel tank and flow into the diesel fuel, causing the water content of the diesel fuel to exceed the standard. When such diesel enters the high-pressure oil pump of the engine, it will corrode the plunger of the precision coupling part, and seriously damage the diesel generator set. Regular maintenance can be effectively avoided.

Engine oil is mechanical lubrication, and the oil also has a certain retention period, generally within two years, long-term storage, the physical and chemical properties of the oil will change, causing the deterioration of the lubrication condition of the diesel generator set when it is working, and it is easy to cause damage to the unit parts. Therefore, the engine oil should be changed regularly. In addition, the filter plays a role in filtering diesel, oil or water to prevent impurities from entering the body. In the diesel oil, oil and impurities are also inevitable. Therefore, the filter plays an important role in the operation of the diesel generator set. At the same time, these oil stains or impurities are deposited on the filter screen wall to reduce the filtering capacity of the filter. If the deposit is too much, the oil circuit will not be unblocked, so that the oil machine will be shocked due to the lack of oil supply when running on load. Therefore, in the normal generator set in use, the three filters are replaced every 500 hours for the common diesel generator sets; the three filters are replaced every two years for the standby diesel generator sets.


The water pump, water tank and water pipeline have not been cleaned for a long time, which makes the water circulation difficult and the cooling effect decreases. If the cooling system fails, the result is that the cooling effect is not good and the water temperature in the unit is too high and the unit shuts down; the water tank leaks If the water level in the water tank drops, the diesel generator set will not work properly. Due to the chemical properties of lubricating oil or oil ester and the iron filings produced after mechanical wear, these not only reduce its lubricating effect, but also accelerate the damage of parts. At the same time, the lubricating oil has a certain corrosive effect on the rubber seal ring. In addition, the oil seal It also deteriorates due to its aging at any time.


The output of the engine power is mainly the fuel burned in the cylinder to do work and the fuel is sprayed through the fuel injector, which makes the burnt carbon deposit deposited on the fuel injector. With the increase of the deposit, the fuel injection amount of the fuel injector will be affected to a certain extent. As a result, the ignition advance angle of the fuel injector is not accurate, and the fuel injection volume of each cylinder of the engine is also uneven, and the working state is also unstable. Therefore, the fuel system is regularly cleaned, and the fuel supply is unblocked when the filter components are replaced. The gas system is adjusted to make it evenly ignite. The control part of the diesel generator is also an important part of the maintenance of the diesel generator set. The unit is used for a long time, the line connector is loose, and the AVR module is working properly.
