Causes of Overspeed in a Diesel Generator


The reason why generators overspeed is generally because the oil pump or electronic actuator is stuck, which causes the throttle to reach the maximum position.

1. Diesel generators are small power generation equipment, which refers to the use of diesel oil as fuel. A power machine that uses a diesel engine as the prime mover to drive a generator to generate electricity. The whole unit is generally composed of diesel engine, generator, control tank, fuel tank, storage battery for starting and control, protective device, emergency cabinet, etc.

2, in the cylinder of diesel engine, The clean air filtered by the air filter is fully mixed with the high pressure atomized diesel fuel injected by the injector. Under the extrusion of the piston upward the volume shrinks and the temperature rises rapidly to reach the ignition point of the diesel fuel. Diesel fuel is ignited, the mixture gas burns violently, the volume expands rapidly, pushing the piston downward, called'do the work '. Each cylinder works in a certain order, and the thrust acting on the piston changes into a force to drive the crankshaft to rotate through the connecting rod, thus driving the crankshaft to rotate.

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 a Household Mini Generator

With the improvement of people's living standards, there are more and more household appliances, such as rice cookers, microwaves, kettles, refrigerators, air - conditioners, washing machines, etc. It can be said that every household has them. But what if there is a power outage? These appliances won't work properly, and our lives will be greatly disrupted. How can we avoid this? We can use household mini - generators to provide convenience in power consumption. So, how to choose a good household mini - generator? Consider the noise level Since it is for household use, when choosing a household mini - generator, we need to check whether the noise will affect the neighbors. Generally, the seller will demonstrate the performance of the generator in advance. A good household generator can reduce noise by about 80%. Choose a generator with a moderate price Due to different brands, there are significant differences in power, and consequently, the price differences of househ...

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...
