柴油機驅動發電機運轉,將柴油的能量轉化為電能,根據其用途的不同,可分為陸用柴油發電機組及船用柴油發電機組;如果按的不同,可分為國產柴油發電機組和進口柴油發電機組;按轉速不同,可分為低速發電機組和高速發電機組。

Diesel engine driven generator, diesel energy into electricity, according to the different purposes, can be divided into land use diesel generators and diesel generator sets; if the brand is different, can be divided into domestic and imported diesel generator diesel generator; according to different rotating speed, can be divided into low high speed turbine and generator.

基本原理

Basic principle

D88尊龙柴油機驅動發電機運轉,將柴油的能量轉化為電能。在柴油機汽缸內,經過空氣濾清器過濾后的潔凈空氣與噴油嘴噴射出的高壓霧化柴油充分混合,在活塞上行的擠壓下,體積縮小,溫度迅速升高,達到柴油的燃點。柴油被點燃,混合氣體劇烈燃燒,體積迅速膨脹,推動活塞下行,稱為‘作功’。

The diesel engine drives the generator to turn the energy of the diesel into electrical energy. In the diesel engine cylinder, the clean air filtered by the air filter is mixed with the high-pressure atomized diesel ejected from the fuel injector, and the volume is reduced and the temperature rises rapidly when the piston goes upward, so as to achieve the ignition point of diesel fuel. The diesel fuel is ignited, the mixture of gas burns sharply, the volume expands rapidly, pushing the piston down, which is called work.

D88尊龙各汽缸按一定順序依次作功,作用在活塞上的推力經過連桿變成了推動曲軸轉動的力量,從而帶動曲軸旋轉。將無刷同步交流發電機與柴油機曲軸同軸安裝,就可以利用柴油機的旋轉帶動發電機的轉子,利用‘電磁感應’原理,發電機就會輸出感應電動勢,經閉合的負載回路就能產生電流。這里只描述發電機組基本的工作原理。要想得到可使用的、穩定的電力輸出,還需要一系列的柴油機和發電機控制、保護器件和回路。

Each cylinder is done in sequence in a certain order, and the thrust on the piston passes through the connecting rod into the force that drives the crankshaft to rotate, thus driving the crankshaft to rotate. The coaxial brushless synchronous alternator and the diesel engine crankshaft are installed in a coaxial way, so that the rotor of the generator can be driven by the rotation of the diesel engine. By using the principle of electromagnetic induction, the generator will output the induced electromotive force and generate the current through the closed load loop. The basic principle of the generator set is described here only. To get the available and stable power output, a series of diesel and generator control, protective devices and circuits are needed.

一臺普通型柴油發電機組主要由柴油機、發電機以及控制系統三部分組成,柴油機和發電機有兩種連接方式,一為柔性連接,即用連軸器把兩部分對接起來,二為剛性連接,用高強度螺栓將發電機鋼性連接片和柴油機飛輪盤連接而成,目前市場上的柴油發電機組使用剛性連接的比較多一些,柴油機和發電機連接好之后安裝在公共底架上,然后配上各種起保護作用的傳感器,如水溫傳感器,通過這些傳感器,直觀地把柴油機的運行狀態顯示給操作員,而且有了這些傳感器,就可以設定一個上限,當達到或超過這個限定值的時候控制系統會預先報警,這個時候如果操作員沒有采取措施,控制系統會自動將機組停掉,柴油發電機組就是采取這種方式起自我保護作用的。

A common type of main diesel generator by the diesel engine, generator and control system composed of three parts, diesel engine and generator has two connections, a flexible connection, by coupling the two parts are jointed together, the rigid connection of power machine steel connecting piece and is connected to the diesel engine flywheel with high strength bolts, the diesel generator set market using rigid connection some more, after a diesel engine and a generator connected are mounted on a common chassis with a variety of sensors, and then play a protective role, such as the temperature sensor, through the sensors, directly to the operation state of the diesel engine is displayed to the operator, but with these sensors, you can set a limit, when reach or exceed this limit when the control system will alarm in advance, this time if The operator did not take measures, and the control system would automatically stop the unit, and the diesel generator set this way to protect itself.
