How to Strengthen The Daily Maintenance of Generator Sets?

Nov. 14, 2023

It should be noted that generator sets are service providers for emergency backup power supply after power failure. Most of the time, generator sets are in standby standby mode. If there is a power outage, the generator set must be "started in an emergency and powered on in an emergency". Otherwise, the backup generator set will have no practical significance. How can this significance be achieved? Practical experience has proven that further strengthening the daily maintenance and repair of generator sets is the most economical and reasonable way, because the generator set is at a standstill for a long time, and various raw materials of the generator set itself will undergo complex chemical and physical changes with engine oil, cooling water, diesel, air, etc., which will then "shut down" the generator set.


diesel generator maintenance


Problem with starting battery failure of the generator set: The battery has not been maintained for a long time, and cannot be replenished in a timely manner after the electrolyte moisture evaporates. There is no starting battery charger configured, and the battery consumption decreases after long-term natural discharge. Alternatively, the charger used must be manually scheduled for equalizing/floating charging switching, as neglecting the switching operation may result in the battery's power consumption not being reached, To completely solve this problem, in addition to configuring high-quality chargers, necessary testing and maintenance are necessary.


Water entering the diesel engine: Due to temperature changes, water vapor in the air condenses and forms droplets that hang on the inner wall of the fuel tank, causing the water content of the diesel to exceed the standard. As a result, diesel entering the high-pressure oil pump of the engine will rust the precision coupling component - the plunger, and in severe cases, it will damage the generator set. Regular maintenance is reasonable to avoid this phenomenon.


Oil retention period (2 years): The engine oil is a mechanical lubrication function, and the oil also has a corresponding retention period. Long term storage can cause changes in the physical and chemical properties of the oil, which can damage the lubrication condition of the generator set during operation and easily cause damage to the generator set components. Therefore, the lubricating oil should be replaced regularly.


The replacement cycle of the three filters (diesel filter, mechanical filter, air filter, water filter) The filter has the function of filtering diesel, engine oil, or water to prevent impurities from entering the body. We propose: firstly, replace the three filters every 500 hours for commonly used generator sets; Secondly, the backup generator unit should replace the three filters every two years.
