How much do you know about diesel generator sets?

Diesel generator sets are small power generation equipment powered by internal combustion engines. When there is a shortage of electricity, diesel generator sets are particularly important. As a self-contained power station AC emergency power supply equipment, it has been used more and more in various fields.

1. The purpose of diesel generator sets

Diesel generator sets are small power generation equipment, mainly using diesel as fuel, and using diesel engines as prime movers to drive generators to generate power. Although the power of diesel generator sets is low, they are very easy to operate and maintain due to their small size and flexibility. When purchasing, we must pay attention to the performance and quality of the selected diesel generator sets must meet the relevant standard requirements, and we must also choose according to the purpose of the unit, the use of the environment conditions and other factors. Since diesel generator sets can be used in three situations: common, standby and emergency, the requirements for diesel generator sets for different purposes are different.

2. The power generation principle of diesel generator sets

Diesel generator sets are mainly driven by diesel engines to convert the energy of 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 injected from the injector. Under the pressure of the piston moving upward, the volume is reduced and the temperature rises rapidly, reaching the ignition point of the diesel. The diesel is ignited, the mixed gas burns violently, the volume expands rapidly, and the piston is pushed downward, which is called "work". Each cylinder works in a certain order, and the thrust acting on the piston is transformed into a force that drives the crankshaft to rotate through the connecting rod, thereby driving the crankshaft to rotate. If the AC generator is installed coaxially with the diesel engine crankshaft, the rotation of the diesel engine can be used to drive the rotor of the generator. Using the principle of "electromagnetic induction", the generator will output an induced electromotive force, and current can be generated through a closed load circuit. In order to obtain usable and stable power output, a series of diesel engine and generator control, protection devices and circuits are also required.

We will use diesel generator sets in many fields. We must correctly understand it in order to use it more efficiently. If you have any questions, please feel free to consult Ningbo Megawatt Machinery Equipment Co., Ltd.!
