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...

What Should You Pay Attention to in Routine Maintenance of Diesel Generator Sets

In modern society, the stability of power supply is directly related to the operation efficiency of enterprises and people's quality of life. Diesel generators have become an indispensable backup power supply or main power source in various industries due to their high efficiency, durability and reliability. However, to ensure the smooth operation and optimal performance of the generator sets, regular maintenance is essential. Here is what you need to pay attention to in the routine maintenance of diesel generators. Keep your generator clean It’s important to keep the generator’s exterior and the generator room clean. Regularly remove any dirt, dust, or debris that may accumulate to on the generator’s surface. This is not only for the sake of beauty, but also for the smooth operation of the unit. Cleaning the generator’s exterior, air intake vents, exhaust outlets and generator room can effectively reduce the risk of generator overheating. In addition, check if the connection bol...
