Tell you how diesel generators work
Working principle of diesel generator:
Diesel engines drive generators to convert diesel energy into electricity.
In the diesel engine cylinder, the clean air filtered by the air filter is fully mixed with the high-pressure atomized diesel injected by the fuel injection nozzle. Under the squeeze of the piston upward, the volume is reduced, and the temperature is rapidly increased to reach the ignition point of the diesel. Diesel is ignited, the mixed gas burns violently, and the volume expands rapidly, pushing the piston downward, which is called 'work'. Each cylinder performs work in order, and the thrust on the piston passes through the connecting rod and becomes the force that drives the crankshaft to rotate, thereby driving the crankshaft to rotate.
By installing the brushless synchronous alternator coaxially with the crankshaft of the diesel engine, 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 the induced electromotive force, and the current can be generated through the closed load circuit. .
Diesel generator set is a type of AC power supply equipment of self-provided power station. It is a small-scale power generation equipment that uses an internal combustion engine as the power to drive a synchronous AC generator to generate electricity.
Modern diesel generator sets are composed of a diesel engine, a three-phase AC brushless synchronous generator, a control box (screen), a cooling water tank, a coupling, a fuel tank, a muffler and a public base. The axial direction of the flywheel housing of the diesel engine and the front end cover of the generator is directly connected by a shoulder to form a single body, and a cylindrical elastic coupling is used to directly drive the rotation of the generator by the flywheel. The connection method is fixed by screws, so that the two This is connected into a steel body to ensure that the concentricity of the crankshaft of the diesel engine and the rotor of the generator is within the specified range.
In order to reduce the vibration of the unit, the joints of the main components such as diesel engines, generators, water tanks and electrical control boxes with the common base are usually equipped with shock absorbers or rubber damping pads.
