​How To Ensure The Reliability Of Diesel Generators

Nov. 09, 2021

Diesel generators used by conventional power sources or backup power sources must be maintained in a timely manner to ensure that they can effectively provide high-quality power throughout their lifespan. A factory with a large model needs diesel generators to drive its plant equipment, and may require internal engineers to maintain its diesel generators. Small companies or owners who only use diesel generators during power outages need regular repairs. In any case, diesel generators need to be inspected to ensure their reliability.


Through the long-term use of diesel generators, it is possible to predict when its components need to be repaired and when they will fail. Developing and following a timely maintenance plan will ensure that your diesel generators operate efficiently and have a longer service life. If you want to know how to maintain diesel generators on a regular basis, then you have come to the right place. Today, Top Power will tell you some tips, you should follow these tips to regularly maintain diesel generators.


Perform regular inspections.

When a diesel generator is running, it is necessary to pay close attention to its exhaust, power and fuel systems in order to find any leakage that may cause dangerous accidents or endanger the lives of operators. The diesel generator is equipped with an internal combustion engine, so correct maintenance is the key to ensuring the smooth and efficient operation of the diesel generator.


If your generator runs for more than 500 hours, you need to repair it, such as changing the oil. For places where the generator runs for a long time, such as a construction site, the maintenance time is shorter because the generator runs on the construction equipment. If your diesel generator is not working well, you should check it to see what is wrong with it. If your generator cannot be repaired, you can consider buying a new one, such as the diesel generator from Dingbo Power, in order to invest wisely and prolong the service life of the equipment.

Lubrication Service

To make diesel generators run as efficiently as possible, the oil must be checked frequently. Turn off the generator and check the oil level of the generator with a dipstick. After stopping, wait a while to allow the oil to return from the upper end of the generator engine to the crankcase. Use a dipstick to measure the oil level. Insert it into the oil inlet and see if the oil level is close to the maximum mark on the dipstick. Be sure to use the same brand of engine oil, because if you change the engine oil brand, it will be different.


When changing the oil of the generator, don't forget to clean the oil filter or replace it when it cannot be repaired. If you don’t know how to inspect oil, please refer to the inspection manual and follow the above steps. You must use high-quality internal combustion engine oil to ensure that your generator runs effectively without any problems.


Fuel system

After a diesel generator has been left for more than a year, it will be contaminated. Therefore, during this period, you must run out of fuel. In addition, the fuel filter should be discharged regularly to ensure that no water vapor is deposited. If you put fuel in a diesel generator, your generator may need to polish the oil. There are many products on the market that can be used to clean the fuel system of generators. However, it is a good idea to empty the fuel tank and replace it with fresh diesel. Precautions include inspection of coolant level, oil, fuel and starting system.


Test battery

Not charging or insufficient battery power are common reasons why diesel generators refuse to start. You should charge the generator to ensure it can be started when needed. In addition, clean them regularly to check their specific gravity and electrolyte levels. Checking the battery output is not the only way to check the battery status. Due to the aging of the generator battery after continuous use, its internal resistance will increase. Only when the battery is under load, can the performance of the battery be checked. It is best to use a battery tester. With the help of resistors, you can check the battery pack condition of the generator. The resistive load meter checks whether the battery is working properly by applying a 5% load to the battery.


To clean the battery, please wipe off the dust and dust on the battery with a damp cloth. At the same time, do not put the solution into the battery unit, otherwise the battery may be damaged. After cleaning the terminal, grease the terminal box to prevent corrosion.


Make sure the generator is clean

As far as diesel generators are concerned, oil droplets are a problem. If your generating set is new, it is easy to find and drip oil. But as you grow older, you have to look around for the source of dripping water. Visual inspection is the best way to find drips and leaking tape. Check your diesel generator frequently to find these problems so that you can correct them and avoid damage over time. The more you use diesel generators, the more services you will need.


Cooling system

After turning off the diesel generator, take out the cover of the radiator and check that the coolant is in the best position. If the coolant level is low, fill it with coolant. Don't forget to check for obstacles or other damages on the outside of the diesel generator radiator. If there is too much dirt or dust, clean it with compressed air.



Take precautions to ensure that your equipment has continuous power supply to meet all your needs, and proper maintenance work can also allow it to provide rated power. Today, Top Power will share with you some daily maintenance tips for diesel generators. Therefore, it is a good idea to follow these suggestions to ensure the long-term use of the generator.
