Diesel generator is a small power generation equipment. diesel oil as fuel and engine generators for prime mover generating power machinery.complete unit is composed of diesel engine generator control box fuel tank starting and control with battery protection emergency tank etc parts.Diesel generators operation, will change diesel energy into electrical energy.In 1897 , the first diesel engine generator in the world was born in Germany's Augsburg (Augsburg).The founder of the MAN company is Rudolf Diesel,he invented the first engine generator.at present engine generators' English name is the name of the founder.
MAN company is the most professional diesel engine manufacturing company in the world today.the largest single capacity can reach 15000 KW.it is is the main power supplier of ocean shipping industry.China's large diesel power plant also depend on MAN company, such as Guangdong Huizhou Dongjiang Power Plant (100000 KW) .At present, this one of the world's earliest diesel engine generator is stored in the German national museum exhibition hall.The overall can be fixed on the basis, positioning use, can be installed in the trailer, for mobile use.
Diesel generator set of non continuous power generation equipment.if the Diesel generators continuous running more than 12 h, the output will be lower than rated power about 90%.Although diesel generator set of power is low, because of its small volume flexible portable necessary is complete, easy operation and maintenance.so it is widely used in mine railway, field site, road traffic maintenance, factory, enterprise and hospital departments.As standby power supply or temporary power supply.
Operating principle:In diesel generators cylinder inside, after air filter filtered clean air and nozzle jet out of the high pressure atomized diesel fully mix.in the piston upward pressure,volume begin smaller, temperature lifts quickly, achieve diesel engine generator 's flash point.diesel was lit, mixed gas intense burning, volume rapid expansion, promote the piston down.known as the work done.each cylinder works done in a certain sequence.The piston thrust through connecting rod became promote crank shaft power, thus promote crankshaft rotation.Brushless synchronous ac generator and diesel engine generator crankshaft coaxial installation.Can use the rotation of thediesel engine generator drive the rotor.Use of electromagnetic induction principle, generator will output induction electromotive force, the closure of the load circuit can produce current.To get astable power output, also need a series of diesel generators and generator control to protect devices and circuit.
