You may not know much about the diesel generator set used in the industry, so we will take you to understand the diesel generator set and its function. It is composed of an engine, generator, and control system, so it is called a generator set. The diesel generator set is a kind of power equipment that uses a diesel engine as a prime mover to drive a synchronous generator to generate electricity. It is a power generating device with quick start-up, convenient operation and maintenance, low investment, and strong adaptability to the environment.
What are the components of a diesel generator set?

Working principle of diesel generator set
The diesel generator set is a kind of power generation equipment with diesel as the main fuel. The diesel engine is used as the motive force to drive the generator (IE, electric ball) to generate electricity, and the kinetic energy is converted into electrical energy and thermal energy. The complete diesel generator set is mainly divided into three parts:
1. Diesel engine.
2. Generator
3. Controller.
In terms of subdivision: base, diesel engine, base fuel tank, generator set, controller (playing a control role and also protecting the set), radiator (air cooling: fan; water cooling: water tank ), silent box and other components. According to the different needs of different places, we divide the generators into fixed and movable trailers. To reduce the noise emitted by the generator sets and reduce the impact on people's work and life, we have prompted designers to design power generation with silent boxes. The unit is to install a metal box on the outside of the generator set with sound-absorbing material inside to protect the generator set. Doors are set on both sides of the box to facilitate people's maintenance and control of the generator set. The silent box not only reduces the noise generated by the generator set but also can be placed outdoors. The box is like a house, sun-proof and rain-proof, saving people the trouble of having no place to build a machine room. Diesel generators are composed of common generator sets and standby generator sets, and the power is divided into common power and standby power accordingly. The standard common power of each generator set is generally 80% of the standby power. According to different needs, usually use the national grid, if you need it due to power failure, please use the standby diesel generator set; if you need to run for a long time, please choose the commonly used diesel generator set, if frequent maintenance, the commonly used diesel generator set runs every year The time can be more than 300 days. The relationship between common power and standby power is: for example, the user needs a 100KW diesel generator set, and the common power of a 100KW standby diesel generator set is 100KW*80%=80KW. That is, the usual power of a spare 100KW diesel generator set is 80KW. If the diesel generator set is equipped with a silent box, the power of the generator set will decrease, generally by about 10%. Therefore, when the user chooses a diesel generator set, the power drop of the silent box should be considered.
The diesel generator set is a combination of a diesel engine and a synchronous alternator. The maximum power allowed by the diesel engine is limited by the mechanical load and thermal load of the parts, so it is necessary to specify the maximum power allowed for continuous operation as the rated power;
Diesel engines should not exceed the rated power, otherwise, their service life will be shortened and accidents may even be caused.
The diesel engine drives the generator to turn the energy of the diesel into electrical energy.
In the diesel engine cylinder, the clean air filtered by the air filter is fully mixed with the high-pressure atomized diesel sprayed from the fuel injector. Under the upward extrusion of the piston, the volume is reduced and the temperature rises rapidly, reaching the ignition point of diesel. The diesel is ignited, the mixed gas burns violently, and its volume expands rapidly, pushing the piston down, which is called work. Each cylinder performs work in a certain order, and the thrust acting on the piston becomes the force that pushes the crankshaft to rotate through the connecting rod, thereby driving the crankshaft to rotate.
Mecca Power's diesel generator sets do a lot of tests before they leave the factory to ensure that we produce high-quality products. Mecca Power provides customers with a variety of diesel generator sets to choose from, and we look forward to cooperating with you
