柴油发电机组结构分析 Structural analysis of diesel generator set

     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，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。传感器起接收和反馈各种信息的作用，真正显示这些数据和执行保护功能的是柴油发电机组的控制系统，控制屏一般安装在发电机上，称为背包式控制屏，也有部分是独立一个屏放置在操作室内，称为分体式控制屏，控制屏通过电缆和发电机以及传感器连接，分别显示电参数和柴油机运行参数。此外，发电机组还有底盘、联轴器、散热器、燃油箱，有的还装设有消声器和外罩。

A regular diesel generator set is mainly composed of three parts: a diesel engine, a generator, and a control system. There are two connection methods for the diesel engine and the generator. One is a flexible connection, which uses a coupling to connect the two parts, and the other is a rigid connection, which uses high-strength bolts to connect the generator's steel connection plate to the diesel engine flywheel disk. There are more diesel generator sets on the market that use rigid connections. After the diesel engine and the generator are connected, they are installed on a common chassis and equipped with various protective sensors, such as water temperature sensors. Through these sensors, the operating status of the diesel engine is intuitively displayed to the operator. With these sensors, an upper limit can be set, and when the limit value is reached or exceeded, it can be set. The control system will issue an alarm in advance, If the operator does not take measures at this time, the control system will automatically shut down the unit, and diesel generator sets use this method to protect themselves. Sensors play a role in receiving and providing feedback on various information. The control system of the diesel generator set is the one that truly displays this data and performs protection functions. The control screen is generally installed on the generator, called a backpack type control screen, or a separate screen placed in the operating room, called a split type control screen. The control screen is connected to the generator and sensors through cables, and displays electrical parameters and diesel engine operating parameters respectively. In addition, the generator set also has a chassis, coupling, radiator, fuel tank, and some are equipped with mufflers and covers.
