Why Is It Important To Regularly Maintain Diesel Generator Sets

Mar. 01, 2022

As a user, I believe that when you purchase a diesel generator set, the generator manufacturer must have emphasized to you that you need to maintain the diesel generator set regularly, so you know why it is very important to maintain the diesel generator set regularly. Is it important? In this article, Jiangsu Starlight Electricity Equipments Co.,Ltd. will tell you the reasons for this from the engine oil.


Most people don't know that engine oil can degrade over time even when the engine is not running at all. If the life expectancy is 1 year, it doesn't mean it can maintain 100% quality in a year. It started to degenerate from day one, but still reached acceptable tolerance levels after a year.


Now, if you extend your service interval to 18 months, that doesn't mean your oil is half as good as new, because you've exceeded the recommended 50% change. Oil does not degrade linearly, which means it may retain its usefulness and then suddenly lose 90% of its lubricating power and other properties.


Due to the nature of using a diesel generator, it rarely runs. Yes, it may run weekly, but that's not enough to burn pollutants in the oil. It is common to see a milky white and jelly-like consistency in the oil when diesel generator specialists carry out annual repairs on these units. This is caused by condensation in the crankcase, which is not uncommon in backup diesel generators.

In China's climate, we can see temperature changes from morning to night. Cold mornings and warm afternoons can cause condensation, and water can settle in the crankcase of the generator. The difference with a generator is that it runs very rarely, so it doesn't reach temperature and stay there long enough to burn water and other contaminants from the oil. If left for too long you should have a clean honey brown oil which is a white milky substance that doesn't work or protect the engine and is difficult to drain from the unit.


As you can see, diesel is a great reason to regularly maintain the health of your backup generators, but there's more.


During the annual maintenance, in addition to changing the oil and oil filter, the technician will also change the air filter and spark plugs as needed, which often happens during the annual maintenance. The technician will also update the onboard firmware and evaluate any work that may have been possible since the last service.


Additionally, the technician will lubricate the mixer components, hinges and locks and clean the equipment from the inside out. General inspections of equipment are included in annual maintenance and go a long way. A generator technician will also test your battery under load (the only proper way to test a battery) and make sure it's good for the coming year. If your unit is liquid cooled, in addition to all of the above, we will service the liquid cooling components and replenish the liquid.


Regular maintenance of the standby diesel generator set can ensure its stable performance, prolong the service life of the generator set and reduce the operating cost of customers.
