If your commercial building loses power during a storm or a power grid failure, you immediately want to know when power can be restored. At this point, if an industrial diesel generator set is configured, you can immediately provide reliable, continuous and stable power for commercial buildings.

        Research shows that the diesel generator market is expected to grow several times over from 2023 to 2030. The increasing demand for diesel generators stems from economic growth, industrialization and intelligence. Companies particularly seek backup power sources during power outages to ensure uninterrupted operation.

        Replacing parts is a common part of the maintenance of industrial diesel generators. Let’s explore the seven most common components that need to be replaced during the maintenance of industrial diesel generators.

        The oil filter of an industrial diesel generator can clean the machine’s oil and prevent it from becoming rough and thickened, which may damage the engine. The frequency of changing the oil filter depends on multiple factors. These factors include the following:

        The condition of diesel generators

        The usage of diesel generators

        Diesel generator type

        Owners of industrial diesel generators should usually replace the oil filter when changing the machine oil. This is usually done once a year or after hundreds of hours of use.

        Please follow the instructions of the diesel generator manufacturer regarding the oil change frequency of the machine and regularly check whether the filter is damaged or worn. Regular replacement of the oil filter may help prevent potential costly engine problems and extend the service life of diesel generators.

        Diesel generator set heater

        As part of the maintenance plan for diesel generators, another component that needs to be replaced on industrial diesel generators is the body heater. The body heater can heat the engine set of the industrial diesel generator, especially when the diesel generator is not in use. They help the generator perform the following operations:

        It starts smoothly when the weather is cold

        Reduce engine emissions and wear

        Save fuel

        The heater of the industrial diesel generator set heats the hydraulic oil or coolant circulating around the engine set. Your coolant can cool the diesel generator and help reduce corrosion (wear).

        The heater of the industrial diesel generator set can also prevent water accumulation in the oil pan of the machine. This is very important because water condensation may clog the oil or fuel filter, causing engine failure.

        Replace your heater after three years or when it malfunctions. This may cause your diesel generator to have difficulty starting or malfunction. One sign that the heater is malfunctioning is that the coolant is too cold. Check the heater once a week and flush it every few years to further ensure the optimal performance of the diesel generator components.

        Diesel generator battery

        The battery is another common component that needs to be replaced on industrial diesel generators. Your industrial diesel generator battery stores electricity and supplies power to your machine when needed.

        Regularly check the battery for cracks, leaks and corrosion. Replace it every 2 to 3 years, or if there are signs of damage, wear, leaks or corrosion. Regular battery replacement may help prevent unexpected malfunctions of industrial diesel generators.

        A diesel generator without a battery cannot start reliably and quickly during a power outage, resulting in the system connected to it lacking the necessary backup power supply.

        Diesel generator fuel filter

        The fuel filter is one of the important components that need to be replaced in industrial diesel generators. This filter can prevent foreign substances such as dust from entering the diesel generator engine, thereby reducing its performance.

        Replace the fuel filter of the diesel generator after 500 hours of use or continuous use for 20 days. Regularly replacing the fuel filter will ensure that your engine receives the best and cleanest fuel, thereby extending the service life of your diesel generator.

        Please remember that there are many benefits to using a diesel generator, including a fast start-up time.

        Diesel generator belt

        The belt of an industrial diesel generator is a flexible material that connects multiple machine components called the rotating shaft in the diesel generator to effectively transmit electricity. Check the belt for cracks every week and make appropriate adjustments. Replace it in accordance with the belt manufacturer’s guidelines. Belts should generally be replaced every three years to ensure their quality and performance.

        Diesel generator voltage regulator

        The voltage regulator of the industrial diesel generator maintains a stable output voltage of the diesel generator. This part detects voltage fluctuations and adjusts the excitation current to stabilize the voltage. This is very important because it ensures that diesel generators receive a reliable and stable power supply.

        Voltage regulators should usually be replaced every few years or every 2,000 hours, whichever comes first. If the voltage regulator fails to adjust the voltage correctly, please replace it as soon as possible. This may cause power surges or fluctuations.

        Signs of a faulty voltage regulator include unstable readings, dimming and flickering lights. A faulty regulator may damage the diesel generator and any equipment connected to it. A normally operating voltage regulator helps diesel generators run efficiently and smoothly.

        The most common replacement parts on industrial diesel generators include the oil filter, fuel filter and heater. Other parts added to the maintenance and repair list of industrial diesel generators include batteries, belts and voltage regulators.
