How often should a diesel generator be maintained?

The battery is not maintained for a long time, and the electrolyte water is not replenished in time after evaporation, and there is no starter battery charger. After the battery is naturally discharged for a long time, the battery capacity will decrease, or the charger used needs to be manually switched between equalization charging and float charging at regular intervals. If the switching operation is neglected, the battery capacity will not meet the requirements. In addition to configuring a high-quality charger, necessary testing and maintenance are necessary to solve this problem.

Due to the condensation of water vapor in the air caused by temperature changes, Water droplets form and hang on the inner wall of the fuel tank, flow into the diesel, causing the water content of the diesel to exceed the standard. Such diesel enters the high-pressure oil pump of the engine, which will rust the precision coupling parts of the plunger. In severe cases, it will damage the unit. Regular maintenance can effectively avoid this.

Due to the chemical properties of lubricating oil and the iron shavings produced by mechanical wear, these not only reduce its lubricating effect, but also accelerate the damage of parts. At the same time, due to the corrosive effect of lubricating oil on rubber sealing rings, the oil seal itself also deteriorates over time, resulting in a decrease in its sealing effect.

The output of engine power is mainly the combustion of fuel in the cylinder, and the fuel is sprayed out through the fuel injector, which makes the carbon deposit after combustion deposit in the fuel injector, and the amount of fuel sprayed by the fuel injector will be affected with the increase of the deposit amount. As a result, the ignition timing of the fuel injector is inaccurate, the amount of fuel sprayed by each cylinder of the engine is uneven, and the working condition is unstable. Therefore, it is necessary to regularly clean the fuel system and replace the filtering components to ensure smooth fuel supply, and adjust the air supply system to ensure even ignition.

The control part of the machine is also an important part of the maintenance and maintenance of the unit. If the unit is used for a long time, the line joints are loose, and whether the AVR module works normally.

The monthly inspection requires the switching of the generator set with the city power, the starting and load test of the generator set, all of which need to be inspected in depth.

During the quarterly inspection, the generator set needs to be in a load of more than 70% to operate for one hour to burn up the mixture of diesel and oil in the cylinder.

Annual inspection is an important part of the maintenance cycle of backup diesel generators, which not only requires quarterly and monthly inspections, but also requires more maintenance projects.

The engine oil is for mechanical lubrication, and the oil also has a certain shelf life. If it is stored for a long time, the physical and chemical properties of the oil will change, causing the lubrication condition of the unit to deteriorate and easily causing damage to the unit parts. Therefore, it needs to be replaced once a year.

A filter refers to the fuel filter, engine filter, air filter, and water filter, which are used to filter diesel, engine oil, or water. In order to prevent impurities from entering the body, oil stains and impurities in diesel are inevitable, so in the operation of the unit, the filter plays an important role, but at the same time, these oil stains or impurities are deposited on the filter wall, which reduces the filter's filtering ability. If there is too much deposition, the oil route will not be smooth, and the oil engine will shock (like a person with lack of oxygen) when running with load because the oil cannot be supplied, so in the normal operation of the generator set, we suggest: the three filters should be replaced every 500 hours for the common generator set; The spare unit's three filters are replaced every year.

Antifreeze is an indispensable heat dissipation medium for the normal operation of diesel generator sets. One is to prevent the water tank of the generator set from freezing, so that it will not freeze and burst in winter; The second is to cool the engine. When the engine is running, using antifreeze as the circulating cooling liquid is very effective. Antifreeze that has not been used for a long time is easy to come into contact with air and undergo oxidation, which affects the antifreeze performance, so it needs to be replaced once a year.
