Diesel generator birth background
MAN is now the world's more specialized diesel engine manufacturing company, single machine capacity can reach 15,000KW. is the main power supplier for the marine shipping industry. China's large diesel power plants also rely on MAN, such as Guangdong Huizhou Dongjiang Power Plant (100,000KW). Foshan Power Plant (80,000KW) are MAN units.
Currently, the world's oldest diesel engine is stored in the exhibition hall of the German National Museum.
Main uses:
Diesel generator set is a small power generation equipment, refers to the diesel fuel, such as diesel, diesel engine as the prime mover to drive the generator to generate power machinery. The whole set is generally composed of diesel engine, generator, control box, fuel tank, starting and control battery, protection devices, emergency cabinet and other components. The whole can be fixed on the foundation, positioning use, can also be mounted on a trailer for mobile use. Diesel generator sets are non-continuous operation of power generation equipment, if continuous operation for more than 12h, its output power will be lower than the rated power of about 90%. Although the power of the diesel generator set is low, but because of its small size, flexible, lightweight, complete supporting, easy to operate and maintain, so it is widely used in mines, field construction sites, road traffic maintenance, as well as factories, enterprises, hospitals and other departments, as a standby power supply or temporary power supply.
Working Principle:
In the diesel engine cylinder, clean air filtered through the air filter and injector nozzles injected high-pressure atomized diesel fuel is fully mixed, in the piston upward pressure, volume reduction, the temperature rises rapidly, reaching the ignition point of diesel fuel. Diesel fuel is ignited, the mixture of gas combustion, the volume of rapid expansion, pushing the piston downward, known as 'work'. Each cylinder in a certain order in turn work, the thrust acting on the piston through the connecting rod into a force that pushes the crankshaft to rotate, thus driving the crankshaft rotation.
Brushless synchronous alternator and diesel engine crankshaft coaxial installation, you can use the rotation of the diesel engine to drive the rotor of the generator, the use of 'electromagnetic induction' principle, the generator will output induced electromotive force, through the closed load circuit can produce current.
Only the more basic principles of generator set operation are described here. A range of diesel engine and generator control and protection devices and circuits are also required to obtain a usable, stable power output.
