Principle and Performance Analysis of Perkins Diesel Generator Set

Perkins diesel generator set has the advantages of excellent shock absorption performance, advanced control system, compact structure and excellent performance. Therefore, after entering the Chinese market, the Perkins diesel generator set was quickly accepted and recognized by the majority of customers, occupied a certain market share, and achieved good results. Therefore, today, Starlight Power Generation Equipment will take you to understand the working principle and performance analysis of Perkins diesel generator sets.

1. Working principle of Perkins diesel generator set

Perkins diesel generator set is a diesel engine that drives the generator to run and converts the energy of diesel into electricity.

In the cylinder of the diesel engine, the clean air filtered by the air filter and the high-pressure atomized diesel fuel injected by the fuel injector are fully mixed. Under the upward extrusion of the piston, the volume shrinks and the temperature rises rapidly, reaching the ignition point of the diesel. The diesel fuel is ignited, the mixed gas burns violently, the volume expands rapidly, and the piston is pushed 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. By installing the brushless synchronous alternator and the crankshaft of the diesel engine coaxially, the rotor of the generator can be driven by the rotation of the diesel engine. Using the principle of 'electromagnetic induction', the generator will output an induced electromotive force, and a current can be generated through a closed load loop. .
