The basic structure of diesel generator is composed of diesel engine and generator.
The basic structure of diesel engine is composed of cylinder, piston, cylinder cover, inlet valve, exhaust valve, piston pin, connecting rod, crankshaft, bearing and flywheel. Diesel generators are generally single-cylinder or multi-cylinder four-stroke diesel engines, I will only talk about the basic principle of single-cylinder four-stroke diesel engines: diesel engine starting through human or other power to turn the engine crankshaft to make the piston in the top closed cylinder reciprocating. The piston in motion completes four stroke: intake stroke, compression stroke, combustion and work (expansion) stroke and exhaust stroke. When the piston moves from top to bottom, the intake valve opens and fresh air filtered by the air filter enters the cylinder to complete the intake stroke. The piston moves from the bottom up, the inlet and exhaust doors are closed, the air is compressed, the temperature and pressure are increased, and the compression process is completed. When the piston is about to reach the top, the injector sprays the filtered fuel into the combustor in a mist form and mixes it with high-temperature and high-pressure air, and immediately catches fire by itself. The high-pressure pressure pushes the piston to work downward and drives the crankshaft to rotate, completing the work stroke. After the power stroke is completed, the piston moves upward from the bottom, and the exhaust door opens to complete the exhaust stroke. Each stroke crankshaft rotates by half a turn. After a number of working cycles, the diesel engine in the flywheel inertia under gradual acceleration into the work.
The crankshaft of the diesel engine drives the generator to turn and generate electricity.
Dc generator is mainly composed of generator housing, magnetic pole core, magnetic coil, armature and brush. Working principle of power generation: when the diesel engine drives the armature of the generator to rotate, because the magnetic pole core of the generator has remanence, the armature coil cuts the magnetic force line in the magnetic field. According to the principle of electromagnetic induction, the current is generated by magnetic induction and the current is output through the carbon brush.
The alternator consists mainly of magnetic materials, which produce a plurality of permanent magnets (called rotors) arranged alternately between the north and south poles, and silicon cast iron, which are wound around an armature coil (called a stator) with multiple series of coils. Power generation principle of work: rotor axial cutting lines of magnetic force driven by diesel engine, the stator pole arranged alternately in iron core formed in the alternating magnetic field in coil and rotor rotation, the direction of the magnetic flux and size transform many times, due to the effect of transformation of the magnetic field, will result in a change to size and direction are in coil conveying the current induced current and the stator winding.
In order to protect the electrical equipment and maintain its normal operation, the current generated by the generator also needs to be adjusted and controlled by the regulator.
