Why should diesel generator set be maintained at intervals?


The diesel generator set is in static standby for a long time. Various materials of generator set will have complex chemical and physical changes with engine oil, cooling water, diesel oil, air, etc. The following faults may occur to the unit.

1. Deterioration of lubricating oil

The lubricating oil of the engine has the function of mechanical lubrication. And lubricants also have a certain shelf life. The physical and chemical properties of lubricating oil will change after long time storage. It will lead to the deterioration of lubrication condition when the unit is working. Easy to cause damage to parts of the unit. Therefore, the lubricating oil should be replaced regularly.

2. Water enters the diesel engine

Because the water vapor in the air changes in temperature, condensation occurs. Water droplets hang on the inner wall of oil tank and flow into diesel oil. The water content of diesel oil exceeded the standard. Such diesel into the engine high-pressure oil pump, will rust the precision coupling plunger. Serious damage to the unit, regular maintenance is effective and can be avoided.

3. Filter replacement cycle

The filter can filter diesel oil, lubricating oil or water. To prevent impurities from entering the machine body. In diesel oil, oil and impurities are inevitable. Oil or impurities will be deposited on the wall of the filter screen, which will reduce the filtration capacity of the filter. If there is too much deposition, the oil path will not be smooth. In this way, when the diesel engine runs with load, it will be shocked because of the lack of oil supply.

The above is why diesel generator sets need maintenance at intervals. I hope I can help you.
