柴油机驱动发电机运转,将柴油的能量转化为电能,根据其用途的不同,可分为陆用柴油发电机组及船用柴油发电机组;如果按的不同,可分为国产柴油发电机组和进口柴油发电机组;按转速不同,可分为低速发电机组和高速发电机组。

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

柴油机驱动发电机运转,将柴油的能量转化为电能。在柴油机汽缸内,经过空气滤清器过滤后的洁净空气与喷油嘴喷射出的高压雾化柴油充分混合,在活塞上行的挤压下,体积缩小,温度迅速升高,达到柴油的燃点。柴油被点燃,混合气体剧烈燃烧,体积迅速膨胀,推动活塞下行,称为‘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.

各汽缸按一定顺序依次作功,作用在活塞上的推力经过连杆变成了推动曲轴转动的力量,从而带动曲轴旋转。将无刷同步交流发电机与柴油机曲轴同轴安装,就可以利用柴油机的旋转带动发电机的转子,利用‘电磁感应’原理,发电机就会输出感应电动势,经闭合的负载回路就能产生电流。这里只描述发电机组基本的工作原理。要想得到可使用的、稳定的电力输出,还需要一系列的柴油机和发电机控制、保护器件和回路。

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.

一台普通型柴油发电机组主要由柴油机、发电机以及控制系统三部分组成,柴油机和发电机有两种连接方式,一为柔性连接,即用连轴器把两部分对接起来,二为刚性连接,用高强度螺栓将发电机钢性连接片和柴油机飞轮盘连接而成,目前市场上的柴油发电机组使用刚性连接的比较多一些,柴油机和发电机连接好之后安装在公共底架上,然后配上各种起保护作用的传感器,如水温传感器,通过这些传感器,直观地把柴油机的运行状态显示给操作员,而且有了这些传感器,就可以设定一个上限,当达到或超过这个限定值的时候控制系统会预先报警,这个时候如果操作员没有采取措施,控制系统会自动将机组停掉,柴油发电机组就是采取这种方式起自我保护作用的。

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.
