Diesel engines drive generators to operate and convert diesel energy into electrical energy. According to their different uses, they can be divided into land diesel generator sets and marine diesel generator sets; according to different brands, they can be divided into domestic diesel generator sets and imported diesel Generator sets: According to different speeds, it can be divided into low-speed generator sets and high-speed generator sets.
1、Fundamental
The diesel engine drives the generator to operate, converting the energy of the diesel into electrical energy. In the cylinder of the diesel engine, the clean air filtered by the air Fleetguard filter is fully mixed with the high-pressure atomized diesel injected from the fuel injector. Under the upward extrusion of the piston, the volume is reduced and the temperature rises rapidly, reaching the diesel The burning point. 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. Install the brushless synchronous alternator coaxially with the crankshaft of the diesel engine, and then the rotation of the diesel engine can drive the rotor of the generator. Using the principle of’electromagnetic induction’, the generator will output induced electromotive force, and current can be generated through the closed load circuit. . Only the most basic working principle of the generator set is described here. To obtain usable and stable power output, a series of diesel engine and generator control, protection devices and circuits are also needed.
