Consequences of Overloading Diesel Generator Sets

It is extremely unsafe for a diesel generator set to operate under overload, and overloading is strictly prohibited. So, what are the consequences of overloading a diesel generator set? Dingbo Power, a generator manufacturer, believes that overloading a diesel generator not only leads to high fuel consumption but also more easily causes generator set malfunctions that require repair.

In general, when the load of a diesel generator set is 80% of the rated load, the fuel consumption is normally at its minimum. If the load increases, the fuel consumption will rise. The fuel consumption of a diesel generator set is directly proportional to the load. However, if the load is lower than 20%, it will have an impact on the diesel generator set. Not only will the fuel consumption of the unit increase significantly, but it may even damage the generator set.

Therefore, to reduce the fuel consumption of a diesel generator, the unit can be operated at around 80% of the rated load. Running at a low load for a long time will actually increase fuel consumption and may even damage the unit. Remember, overloading a diesel generator set not only results in high fuel consumption but also more easily causes malfunctions that require repair.

Overloading a diesel generator set can easily lead to the following malfunctions:

1.It is easy to damage the engine cylinder gasket.

2.It can easily increase the thermal and mechanical loads on the cylinder liner.

3.The turbocharger of the ultra - silent generator set will turn red. After being exposed to high temperatures for a long time, the turbocharger will be damaged.

4.Malfunctions such as cylinder scoring and bearing burnout are also likely to occur.

5.The generator will have difficulty dissipating heat due to overloading, and the coils may be punctured and burned out.

After a diesel generator set operates under overload, oil may overflow from the fuel tank opening, and the high - pressure oil pipe may wear and leak. When a diesel generator set is delivered and accepted, it is an essential item for the generator manufacturer to train users on the normal operating procedures of the diesel generator set. Users must study these procedures carefully and put them into practice. Many serious malfunctions often occur due to users' negligence and non - standard operations, which we must take as a warning.

Diesel Generator Power Ratings: Standby vs Prime vs Continuous

Diesel generator sets are commonly used in a variety of sectors due to their dependable performance and high efficiency. They can be used for emergency power supply in the event of a power cut or used in places without connection to a power grid. When selecting a diesel generator for your home or business, you need to consider many factors, such as generator’s ratings. In this article, we’ll explain the three basic rating types - standby, prime, and continuous in diesel generators. ISO-8528-1:2018 defines basic generator set rating categories based on four operational categories: Emergency Standby Power (ESP), Prime Power (PRP), Continuous Power (COP) and Limited-Time Running Prime (LTP). Read on and learn the application of power ratings for engines used in generating sets. Standby Power Rating Standby Power(ESP) is used to supply emergency power when the external power supply is interrupted, such as power outages. Standby power rated generators can supply reliable electricity as t...

How to Choose Efficient Diesel Generators for the Film and Television Industry?

In the film and television industry, the stability of the electricity supply during filming is crucial. Whether the equipment are the cameras or the lighting equipment on the filming site, or the post-production equipment, they all need stable and reliable power support. Unstable or interrupted power can result in interrupted filming, damage to equipment, and even affecting the progress and quality of the entire project. Therefore, investing in high-efficiency diesel generator sets has become an important measure for the film and television industry to ensure the reliable power supply for shooting. Determine the power requirements Before choosing a diesel generator set for the film and television industry, it’s necessary to figure out the total power needs, including the electricity demand of the shooting location, the total power of the electrical equipment and the time of using electricity. Also consider whether there are special needs for the generators such as low noise level and...
