Generator Principle

 

1. Generator Overview:

A generator is a mechanical device that converts other forms of energy into electrical energy. It is driven by a water turbine, a steam turbine, a diesel engine or other power machinery, and converts the energy generated by water flow, airflow, fuel combustion or nuclear fission into mechanical energy and transmits it to the generator. It is then converted into electrical energy by a generator. Generators are widely used in industrial and agricultural production, national defense, science and technology and daily life.
Diesel generator is a kind of power generation equipment, which refers to the power machinery that uses diesel oil as fuel and uses diesel engine as prime mover to drive the generator to generate electricity. The whole set is generally composed of diesel engine, generator, control box, fuel tank, battery for starting and control, protection device, emergency cabinet and other components. It can be used for daily power generation and emergency power generation in various households, offices, large, medium, and small enterprises.

2. The Classification of Generators Can be Summarized as Follows:

Diesel generator: DC generator and alternator
Alternator generator: synchronous generator and asynchronous generator (rarely used)
Alternators can also be divided into single-phase generators and three-phase generators

3. Working Principle:

The working principle of the diesel generator is that the diesel engine drives the generator to run.
In the cylinder, the clean air filtered by the air filter is thoroughly mixed with the high-pressure atomized diesel fuel injected by the fuel injector. Under the upward extrusion of the piston, the volume decreases and the temperature rises rapidly, reaching the ignition point of diesel.
The diesel is ignited, the mixture burns violently, and its volume expands rapidly, pushing the piston downward. Each cylinder works sequentially 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.
